1. SAFETY INSTRUCTIONS

A. Keep this instruction booklet where it can always be easily consulted by the operator or by maintenance personnel.

B. Warning: hot components may be inside the plastic housing of the controller.

C. No user-serviceable parts are inside the plastic housing of the controller. D. The controller and any device connected to it must be installed in compliance

with the Safety Regulations in force. If these regulations are not respected during installation, and if our product is not installed in compliance with the indications given in this instruction booklet, then this may cause a reduction in the safety level of the controller. In particular, the ambient operating conditions for the controller given in our technical data must be complied by; absolutely avoid: water condensation or excessive humidity, exposure to steam, corrosive - or toxic gases, contact with any type of liquid, and exposure to shocks or to extreme vibrations. Not respecting the above indications could cause malfunctions and entail unpredictable consequences, e.g., in the worst cases, dangerous electrical discharges on probes or other parts of the instrument.

E. This controller is guaranteed by Honeywell to have a specific immunity level,

in compliance with CE regulations, against irradiated and conducted electromagnetic disturbances. By irradiated electromagnetic disturbances we recommend to screen the controller with a metal screen connected to ground. To eliminate, or at least reduce conducted disturbances, which not only could propagate through the mains but also through the probes or the connected loads, carry out the electrical wiring according to the indications given in this instruction booklet. If necessary, use filters with suitable characteristics for specific applications and for the detected type of disturbance.

F. If the type of probe to be used will directly touch foodstuffs, make sure that it

is in compliance with the local sanitary and health regulations. G. The controller has no type of protection for the connected loads, so these

must be protected against short circuits, over-current or over-voltage, excessive temperature, etc., by suitable protective means (such as fuses, suitable thermo-magnetic circuit breakers, thermal protections, etc.). At any rate, the electrical power lines that supply both the controller and any other device connected to it, either directly or through a transformer, must be manufactured in compliance with the regulations in force.

H. When the controller is used in appliances where any malfunction of said

controller could cause a form of risk to persons, animals or things, it is ABSOLUTELY MANDATORY to provide a suitable protective/safety device, in addition to the controller, which independently starts to operate in case of a failure.

I. The controller cannot be used as a critical component in life-support devices

or systems without a written approval expressly issued by the legal representative of Honeywell.

CAUTION Disconnect the power supply before you begin installing the Icon controller. Do not reconnect the power supply until you have completed installation.

2. GENERAL DESCRIPTION

The microprocessor-based electronic Honeywell Icon 100 Series Refrigeration Controllers are designed to measure, display, and control the temperature of refrigeration cases and coldrooms. The Icon 100 Series are powered by AC 230 V, 50/60 Hz, and can read from two thermistor probes (thermostat and / or defrost probes), and has up to three relay outputs (compressor, defrost and fan). All of the controllers operating parameters are configurable using a four button keypad on the front of the temperature display. Access to the configuration parameters menu is achieved through the front panel keyboard by following a very simple security procedure, after which the required parameter values can be set quickly and easily. A Honeywell NTC 2k Ohm probe is supplied as standard with Icon and has a measuring range of –50 to +90oC. (-58 to +194 oF), that can be installed up to 10 meters (30ft) from the controller without requiring instrument recalibration. Icon can also use the PT1000 thermistor probe with a measuring range of –50 to +90oC. (-58 to +194 oF). Please note: you cannot have a combination of NTC or PT1000 probes on a single controller. All programming data is stored in a non-volatile memory (EEPROM), where it also remains during a power failure. The Icon 100 Series have the following features.

• display the measured case temperature as well as the alarm messages that refer to faulty cooling/refrigeration plant functions.

• control the measured temperature through the thermostat probe in order to maintain it under a set limit value (main set point + differential), by activating the compressor to lower said temperature every time it exceeds the main set point + differential value.

• control the defrost cycles of the cooling/refrigeration plant manually or through the programmed mode; in the latter mode it is possible to set the times of up to four daily defrost cycles (112SR & 132SR models only)

• control the defrost cycle time as well as the successive startup of the cooling/refrigeration plant fan through the defrost probe. (112SR & 132SR models only)

• Honeywell Genus® Network compatible. • Optional Genus® comms. Module.

4. INSTALLATION

4.1. Introduction The controller must be installed in a place where it is protected from extreme vibrations, impacts, water, corrosive gases, steam etc. and where temperature and humidity do not exceed the values given in the technical specification table (see page 6). The same instructions are also valid for the probes.

4.2. Thermistor Probe The thermistor probe must be installed in a place where it is protected from direct airflow (i.e., away from fans or doors), so that the average temperature can be measured.

4.3. Defrost Termination Probe The defrost termination probe must be installed in the coldest area between the evaporator fins, i.e., where the most ice will form, and not near the defrost heater or near the area that warms up first during defrosting, in order to avoid early termination of the defrost cycle.

4.4. Electrical Wiring We would recommend protecting the controller power supply from electromagnetic disturbances, voltage peaks, etc. This can be easily done while wiring by following the instructions below:

a) separate the power supply cables of the compressor, motors, etc. from those of the controller;

b) keep the probe cables, the controller power supply cables, and the load power supply cables separate and sufficiently far away from each other, so they do not cross or form spirals.

4.5. Applications in Critical Environments When used in particularly critical industrial environments the following precautions can also be useful:

a) use mains network filters to reduce disturbances at the controller power supply, as well as filters for the loads in order to attenuate disturbances at the controller relay outputs;

b) use screened probe cables connected to the grounding system, if the previous indications are not sufficient;

c) in the event of strong radio disturbances screen the entire device with a metallic screen and connect it the grounding system.


EN2B-0002UK07 R0404 8

4.6. Fitting

lcon is supplied in a panel-mount enclosure. While fitting the controller we recommend to leave enough room at the back in order to avoid compressing or excessively bending the cables. Overall instrument size and panel cut-out dimensions are given in the Fig. 1. below.

Fig. 1. Fitting Icon

4.7. Connections We recommend the use of wire gauges adequate for the given load power ratings in order to avoid damage to the screw connector. ICON-111S/SR Models

5. CONTROLLER SET-UP

5.1. Front Panel The front panel, as shown in the figures below, includes 4 keys, i.e., the UP key (increase), the DOWN key (decrease), the SET key (setting), the MANUAL DEFROST key, and a three-digit display with three signal LEDs: DP1, DP2, and DP3.

Fig. 5. Icon Front Panel

5.2. Keys Functions

Up Key: When depressed, while programming either the main setpoint or any parameter configurations, will increase the displayed value. Down Key: When depressed, while programming either the main setpoint or any parameter configurations, will decrease the displayed value. Set Key: When depressed and then released, during normal controller functioning, will display the main setpoint Set Key: Depressing this key for 5 seconds will allow you to enter the configuration menu, through which one can change the parameters listed in the Table of Configuration Parameters (see page 14). Manual Defrost Key: Depressing this key for 3 seconds during normal controller state will start the manual defrost cycle. Note: It is not possible to initiate a defrost if controller is in an alarm state. Up and Down Keys: Depressing these keys simultaneously for 5 seconds will lock or unlock access to the parameter configuration menu.

5.3. Display Functions As well as the temperature value display during normal functioning, the display also shows the value of the main setpoint and the configuration parameter values, as well as the codes of the latter and possible error messages.

5.1 LED Indications DP1 blinking: indicates that the controller is in either the parameter programming mode or that the main setpoint is being set.

• DP1 ON: indicates that the compressor output is activated (all models). • DP2 ON: indicates that the defrost output is activated (Icon 132S & SR). • DP3 ON: indicates that the fan output is activated (Icon 132S & SR).

5.4. Display of Main Setpoint When SET key is depressed once, the display will show the main setpoint for 15 seconds.

5.5. Display of the Defrost Termination Probe Temperature When keeping the UP key depressed, the defrost termination temperature, detected by the defrost termination probe, will be shown on the display.

5.6. Changing the Main Setpoint 1. Depress the SET key (the display will show the current main setpoint value;

DP1 – compressor LED – will start to blink). 2. Change the main setpoint value shown on the display by either using the UP

or the DOWN key (the change must be made within 15 seconds after the SET key was depressed otherwise the controller will switch back to the normal operating mode and shows the running temperature). The main setpoint cannot be programmed outside the limit values fixed through parameters d3 and d4. (see Table 2 in Section 6 for d3, d4 parameters)

3. Confirm the newly set value by depressing the SET key (the key must be depressed within 10 seconds from completion of the previous operation, otherwise the controller will switch back to the normal operating mode and show the running temperature without modifying the main setpoint. When the newly fixed main set point value blinks for 2 seconds, this means that the acceptance and storage of this new data is confirmed).

5.7. Changing The Configuration Parameters 1. Depress the SET key for 10 seconds, (the display will show the code of the

first parameter and, after two seconds, its value; DP 1 will start to blink); 2. Modify the displayed value of the first parameter using the UP or DOWN keys

the modification must be made within 15 seconds after the SET key was released otherwise the controller will switch back to the normal operating mode and show the running temperature).

3. Confirm the newly set value by depressing the SET key (the key must be depressed within 10 seconds from completion of the previous operation, otherwise the controller will switch back to the normal operating mode and show the running temperature without modifying the parameter; when the newly set value blinks for 2 seconds this means that the acceptance and storage of this new data is confirmed. After the new value is stored the controller will display the second parameter code and after 2 seconds the related value).

4. Modify the displayed value of the second parameter and store the new data by repeating the procedure described in the two previous points. Proceed in this manner with all the other parameters (once the last parameter value has been stored, the display will again show the code of the first parameter and after 2 seconds its related value. After 15 seconds the controller will switch back to the normal operating mode and show the running temperature).


EN2B-0002UK07 R0404 12

Note: In order to leave a configuration parameter unaltered during the modification procedure, depress the SET key, after having stored the modified value of the previous parameter, the controller displays the code of the parameter to be left unaltered. In this manner the controller proceeds and shows the code and then the value of the parameter following the unaltered one. The changes made relating to time values are only effective after the currently running timed cycles end, while changes to the set points are effective immediately.

5.8. Locking / Unlocking the Keypad Keeping the UP and DOWN keys simultaneously depressed for 10 seconds makes it possible to lock/unlock access to the configuration parameters menu. The controller will signal this by either showing the blinking message "PoF” (push-button OFF = keypad locked) or "Pon" (push-button ON = keypad unlocked). It is very useful to lock the keyboard in order to avoid tampering with the configuration parameter values by non-authorised personnel. Note: The controller will default to “PoF” (keypad locked) if power is interrupted or switched off.

5.9. Setting and Displaying the Real Time Clock The Real-Time Clock (RTC) operates on a 24 hour cycle (00:00…23:50) on Icon models: ICON-111SR, ICON-112SR & ICON-132SR. 1. The current time set in the RTC can be displayed by simultaneously depressing

and releasing the DEFROST and SET keys.

The display will show either two or three numbers. The first one or two numbers represents the hours, the last number always represents the minutes (displayed in multiples of 10). Example: 24 = 02 hours and 40 minutes. 173 = 17 hours and 30 minutes.

2. By depressing the DOWN key it is possible to display the current hours of the clock. If you continue to press the key, the setting of the hours is modified and the value increases in a progressively faster mode.

3. By depressing the UP key it is possible to display the current minutes of the

clock. If you continue to press the key, the setting of the minutes is modified and the value increases in a progressively faster mode.

Ten seconds after the last activation of the key, the displayed time disappears and the display case / cold-room temperature re-appears again.


EN2B-0002UK07 R0404 13

5.10. Setting the Daily Defrost Cycles on the Real Time Clock It is possible to set-up 4 defrost cycles per day on Icon models: ICON-111SR, ICON-112SR & ICON-132SR. The time parameters regarding this function are d30, d31, d32 & d33 (See Section 6, Table 2). Notes:

1. In order to activate a defrost cycle it is necessary to set the defrost cycle starting time in at least one of the parameters (d30…d33)

2. To be recognized as valid, the time must between the values of 001 and 235 (00:10…23:50 hrs) where first two numbers are the hour (00…23) and last number is minutes in multiples of 10 (0...50).

3. Any other value will not be accepted, and will be interpreted by Icon as being a non-valid setting and therefore not associated to any defrost cycle.

4. If you input the value 000 (00:00) midnight to parameters d30, d31, d32 & d33, this DISABLES the defrosting real-time clock.

Procedure:

1. Depress SET key for 10 seconds to activate parameter menu. 2. Scroll to parameter d30 and enter time value 3. Press SET key, the time value will blink for 5 secs. Icon will then

automatically go to parameter d31, (2nd defrost time parameter) 4. Continue to set time parameters d31, d32 and d33, as required. 5. Wait for Icon to time-out of parameter setting mode (20 secs.).

Important: With regard to parameter d8, (time interval between defrost cycles), please remember that the value set in said parameter (d8) must be greater than the maximum set interval between two defrost cycles start times set in parameters d30…d33. (Not applicable to Icon ‘S’ models.) Example: d30 = 050 (05:00) d31 = 113 (11:30);

d32 = 153 (15:30) d33 = 235 (23:50) Therefore: d8 > 18 hours 50 mins.

EN2B-0002UK07 R0404 15

7. PARAMETER DESCRIPTION

d1 Main setpoint: The controller Temperature at which the compressor is switched on. This must be fixed within the limits set in parameters d3 and d4. d2 Differential (hysteresis): The differential is the temperature added to the set point at which the compressor is switched off. A very small differential range determines a very accurate control of the temperature, but also causes the compressor to turn ON and OFF too often. d3, d4 Lower and upper limit of main setpoint: These parameters respectively fix the minimum (d3) and maximum (d4) limits of the main setpoint. The main setpoint cannot be programmed outside these limit values. d5 Minimum time interval between the deactivation and successive activation of the compressor: d5 fixes the time interval which starts when the compressor is turned OFF and during which it is not possible to reactivate it, in order to allow the internal refrigeration circuit pressures to stabilize and save excessive switching of compressors. d6 Maximum temperature alarm differential: This parameter fixes the increase of the control temperature with respect to the main setpoint, which, when exceeded, causes the controller to activate the alarm output. After the Temperature alarm delay period (d7) the display will alternate between "HtA" and the actual temperature reading. d7 Maximum or minimum temperature alarm delay: The time interval in minutes between the alarm set point being reached and the controller going into alarm mode. d8 Intervals between defrost cycles: This parameter fixes the time interval between the end of a defrost cycle and the beginning of the following one. When starting a manual defrost cycle, time interval counting restarts from zero. The beginning of the first defrost cycle is regulated by parameter d34. d9 Maximum defrost cycle time: By time-controlled defrosting, this parameter fixes the maximum duration of a defrost cycle; d10 Target Defrost temperature: This parameter fixes the defrost termination temperature, which, when reached, ends the defrost cycle for safety purposes, defrosting ends after the time set in d9 ends regardless of temperature. (only on Icon SR range) d11 Time period for supplementary defrost: After the defrost termination temperature is reached the defrost heater is de-activated. If the defrost maximum time period d9 has not been reached then the defrost heater can be cycled on and off around the termination temperature (with a differential of 2 below the termination set point). d12 Defrost recovery time: This is the time interval between the end of defrost and the display showing actual control temperature. During this period the display will show the control temperature before defrost started. d13 Compressor function during the defrost cycle: This parameter indicates the compressor function mode during a defrost cycle, i.e. always OFF when d13=0, always ON when d13=1. d14 Drain down : This parameter sets the time interval that starting at the end of a defrost cycle and during which the compressor remains OFF to allow optimum drying of the evaporator. d15 Fan function mode during normal controller operations: This parameter indicates the fan function mode during normal controller operations, i.e., synchronised with the compressor when d15=0, always ON when d15=1 (only for model ICON-132S & ICON-132SR). In both cases the fan remains OFF during defrosting and then for the time set in parameter d16.


EN2B-0002UK07 R0404 16

d16 Fan activation delay at controller start-up and defrost-end: This parameter sets the time interval that starts at controller start-up or at the end of a defrost cycle, during which the fan must remain off in order to not introduce warm and humid air into the case or coldroom (only for model ICON-132S & ICON-132SR). At the end of this time interval the fan will be activated when the defrost termination temperature drops and reaches the value set in parameter d17. d17 Fan activation temperature at controller startup and defrost-end: This parameter sets the defrost termination temperature value, detected by the defrost-termination temperature probe, and below which the fan will be activated when the time set in parameter d16 ends (only for model ICON-132S & ICON-132SR). d19 Display Offset: This parameter fixes the positive or negative correction applied to the value detected by the temperature probe and the value shown in the display. d20 Probe Type Selection: 2k NTC and PT1000 probe selection. Where 0= PT1000 and 1= 2k NTC. d22 Unit of measure: This parameter fixes the unit of measure regarding the temperature, i.e., oC if d22=0 or oF if d22=1. d23 Compressor function during a probe failure: This parameter fixes the compressor operating mode during a temperature probe failure. If d23=0, the compressor is deactivated and remains that way until the failure is repaired. If d23=1, the compressor is activated and remains that way until the failure is repaired. Whenever a failure occurs, if d23=2, the compressor alternates a time interval set in parameter d25, during which it remains deactivated, with a time interval set in parameter d24, during which it remains activated and so on. d24 Compressor ON-time during a probe failure: This parameter sets the time interval. That alternates with the time interval set in parameter d25, during which the compressor must remain activated during a probe failure and if parameter d23=2. d25 Compressor OFF-time during a probe failure: This parameter sets the time interval, that alternates with the time interval set in parameter d24. During which the compressor must remain deactivated during a probe failure and if parameter d23=2. d26 Defrost control via real-time clock or Genus® network: local defrost control for stand-alone controller via real-time clock or remote defrost control for networked controller when connected to Genus®. d27 Stub number: number given to identify refrigeration stub from 0…99 when connected to, and viewed from, a Genus® network. d28 Case number: number given to identify refrigeration case from 0…9…A…U when connected to, and viewed from, Genus® network. d29 Connect to Genus® Network: Command which starts / stops network connection to a Genus® front end. d30 Defrost cycle 1 start time: This parameter sets the time for the first defrost cycle within a 24 hour period. d31 Defrost cycle 2 start time: This parameter sets the time for the second defrost cycle within a 24 hour period. d32 Defrost cycle 3 start time: This parameter sets the time for the third defrost cycle within a 24 hour period. d33 Defrost cycle 4 start time: This parameter sets the time for the fourth defrost cycle within a 24 hour period. d34 First defrost cycle after controller startup: This parameter fixes the time interval, starting at controller startup, after which the first defrost cycle is activated. If d34=0, the first defrost cycle starts 10 minutes after controller startup. If d34=1, the first defrost cycle starts after the hours set in d8. d38 Minimum temperature alarm differential: This parameter sets the temperature below the set point (d1) which activates an under-temperature alarm, subject to the alarm delay d7.

8. CONNECTING TO HONEYWELL GENUS® NETWORK The Icon controller has an optional Genus® communication module (Part Number: ICON-COMMS) which allows logging onto a Genus® network for remote alarm monitoring and defrost control.

8.1. Icon Controller Identification on Genus® Network Icon has to be given a name (alias) in order to log onto the network. The following naming convention is required for Genus® network identification and defrost capabilities. The Icon controller name is displayed as ‘ICXX-Y’ on Genus® network. Where ‘XX’ is the STUB number and ‘Y’ is the CASE number.

Fig. 6. Icon identification on Genus® Network

8.2. Network Logging-On Procedure 1. Power down controller. 2. Connect network cable to Genus® comms module. 3. Insert Genus® comms module into the Genus® comms socket at the rear of

the Icon controller. 4. Power up controller. 5. After controller power up procedure (5 secs.) enter parameter configuration

setting mode (see section 5.8). Note: Key pad may need to be unlocked (Depress UP and DOWN keys for 10 seconds until you see ‘Pon’ displayed).

6. Scroll to parameter d27 and enter stub number ‘XX’ e.g. 13 7. Press SET key, the stub number will blink for 5 secs. Icon will then

automatically go to parameter d28 - (case parameter). 8. Enter case number ‘Y’ e.g. 4 9. Press SET key, the case number will blink for 5 secs. Icon will then

automatically go to d29 – (Genus® enable / disable parameter). 10. Scroll value to 1 and press SET key which will blink for 5 secs. (Note that if

Value=0 then Icon controller is not linked to Genus® system). 11. Wait for Icon to time-out of parameter setting mode (20 secs) 12. Icon will now automatically log-on to Genus® front end (PCVisor /

Supervisor) 13. Controller alias will be visible on front-end within 2 minutes. 14. Refer to your front-end literature for further information regarding accessing

Icon via Genus® network. *1: A stub number (XX) represents the refrigeration section where the Icon controller is

situated within the supermarket. *2: A case number (Y) represents the case within the stub. Also note that the case

representing “K” is displayed as ‘ :- ‘ on the Icon display

Example of Stub number (0…99) Parameter 27 *1

Example of Case Number (0…9, A…U) Parameter 28 *2

9. PROGRAMMABLE HOTKEY The Icon controller has an optional programmable HotKey (Part Number: ICON-KEY1). When the controller is switched ON, it is possible to upload the parameter configurations of the controller to the HotKey, or vice-versa to download parameter configurations from the HotKey to the controller.

9.1. HotKey Uploading Procedure To upload the parameter configuration from the controller to the HotKey, proceed in the following manner.

1. Connect the HotKey to the HotKey connector on the rear of the controller 2. Briefly press the UP + DOWN keys simultaneously. The “MEM” message

will appear on the display.

3. Press the UP key for 5 seconds until the “uPL” message appears on the display.

4. If the procedure was carried out correctly, then the initial ambient temperature will appear on the display again.

5. If the procedure was not carried out correctly then the “Err” message will appear on the display. In this case check that the HotKey is inserted correctly and try the procedure once more.

9.2. HotKey Downloading Procedure To download the parameter configuration from the HotKey to the controller, proceed in the following manner.

1. Connect the HotKey to the HotKey connector on the rear of the controller. 2. Press and release the UP + DOWN keys simultaneously. The “MEM”

message will appear on the display.

3. Press the DOWN key for 5 seconds until the “doL” message appears on the display.

4. If the procedure was carried out correctly, then the initial ambient temperature will appear on the display again.

5. If the procedure was not carried out correctly then the “Err” message will appear on the display. In this case check that the HotKey is inserted correctly and try the procedure once more.

6. If connected to Genus® network, manually re-configure controller parameters d27, d28 and d29 to reflect new address and logging status of controller. (see note below).

Note: Parameters d27 (stub number), d28 (case number) & d29 (Genus® network

logging status) are automatically set to ‘0’ (default) when Hotkey download to new controller is complete. This ensures that there is no conflict with two or more controllers having the same network address.

Reconfigure these parameters to create new address for controller as well as network logging status. E.g. stub = 14, case = 5, Genus logging = 1 (on).
