Protection and safety systems

Warning.Danger of burns and electric shocks. Access to the HIU should be by suitably qualified and authorised personnel only.

It is important that the access to the HIU is made only by suitably qualified and authorised personnel: the cabinets are provided with key locking.

Controls and maintenanceWarning.The installation should be undertaken by suitably qualified and authorised personnel only.Observe the EU norms and regulations concerning the use (installation, fixing, etc.), the operation, the recalibration and the replacement the meters. Please refer to the assembly instructions supplied with any meter.

Warning.Before connecting the template to the HIU, remove the lock nuts from the threaded connections.

Heating circuit pressurePeriodically inspect the pressure of the heating circuit by using the manometer (Components - Ref. 22): the pressure value must be maintained over 1 bar (pressure values under 1 bar can damage the circulator by cavitation). A pressure switch with 0,8 bar settings is provide to protect the circulator.

Warning.Circulator stops if the pressure is below 0,8 bar due to the pressure switch device. Please, refill the system to restart the circulator.

Provide a filling system for the heating, that is a connection from the sanitary side to the heating with a backflow preventer. during filling be aware that the safety valve will activate at 3 bar (Components - Ref. 23). Warning: danger of burns. In order to eliminate the air in the heating circuit, use the air vent (Components - Ref. 1 and Ref. 17).

Safety valvePeriodically operate the manual handwheel of the safety valve (Components - Ref. 23). Be careful the discharge of water may be hot.Warning: danger of burns.

AdjustmentsHeatingAdjust the heating temperature using the thermostatic head (Components - Ref. 8):

Position 1 2 3 4 5

Temperature [°C] 23 34 45 56 67

Warning.Provide a safety thermostat for the low temperature heating applications.

If you notice that the rating temperature of the heating is higher than the set value, the flow of the primary may be too high and the thermostatic head is not able to close.To balance the heating production functions, you can adjust the dynamic balancing valve (Components - Ref. 2). Finally, it is possible to change the heating power by modifying the circulator speed using the red knob (Components - Ref. 21).

Electrical connectionsOn the top left of the HIU there is an electrical box IP55 (Componenti - Ref. 24).

Primary: inlet (D) and outlet (C).The primary circuit consists of an air vent valve, a dynamic balancing valve, a motorized two-way zone valve, a brass spacer and an housing for installing the temperature energy meter probe.Instead of the brass spacer, a thermal energy meter (Components - Ref. 4) can be mounted, by installing its own temperature probe in the special housing (Components - Ref. 5).The zone valve manages the cooling by means of a chronothermostat (to be ordered separately).

Cooling: delivery (F) and return (G).The Cooling circuit consists of a heat exchanger, a circulator, a ball valve for circulator maintenance, a pressure switch, an air vent valve, an expansion vessel, a safety valve and a pressure gauge.It is necessary to provide a filling system for cooling, i.e . a connection from the domestic water side to the cooling side with an appropriate backflow preventer.

Protection and safety systems

Warning.Danger of burns and electric shocks. Access to the HIU should be by suitably qualified and authorised personnel only.

It is important that the access to the HIU is made only by suitably qualified and authorised personnel: the cabinets are provided with key locking.

Controls and maintenanceWarning.The installation should be undertaken by suitably qualified and authorised personnel only.Observe the EU norms and regulations concerning the use (installation, fixing, etc.), the operation, the recalibration and the replacement the meters. Please refer to the assembly instructions supplied with any meter.

Warning.Before connecting the template to the HIU, remove the lock nuts from the threaded connections.

Cooling circuit pressurePeriodically inspect the pressure of the cooling circuit by using the pressure gauge (Components - Ref. 12): the pressure value must be maintained over 1 bar (pressure values under 1 bar can damage the circulator by cavitation). A pressure switch with 0,8 bar settings is provided to protect the circulator (Components -Ref. 8).

Warning.Circulator stops if the pressure is below 0,8 bar due to the pressure switch device. Please, refill the system before restarting the circulator.

For the refilling of the cooling system, provide a filling loop with a backflow preventer between the Domestic Water System and the cooling system.During filling be aware that the safety valve will activate at 3 bar (Components - Ref. 13). Warning: danger of burns. In order to eliminate the air in the heating circuit, use the air vent (Components - Ref. 1 and Ref. 7).

Safet valvePeriodically maneuver the safety valve handwheel (Components - Ref. 13). Pay attention to the leakage of liquid from the drain.

AdjustmentsIf the nominal temperature of the cooling is higher than the set value, the flow rate of the primary could be too high.To balance the cooling function, the dynamic balancing valve (Components - Ref. 2) can be adjusted.Finally, it is possible to change the cooling power by changing the speed of the circulator using the red knob (Components - Ref. 11).

Electrical connectionsAt the top left of the HIU is an IP55 electrical box (Components - Ref. 14).

A TMV2+TMV3 thermostatic mixing valve regulates the temperature of domestic hot water (DHW).

HEATING: delivery (F) and return (G).The heating circuit is composed of the heat exchanger, a circulator, a ball valve, a pressure switch, an air vent valve, an expansion vessel, a safety valve and a manometer.For the heating provide for a filing system, that is a connection from the domestic to the heating, with an appropriate backflow preventer.

PRIMARY: inlet (D) and outlet (C).The primary circuit is divided into two sides: one is for the heating handling, the other is for the production of DHW. It is composed of an air vent valve, a dynamic balancing valve, a 2-way zone valve motorised, a brass spacer, an housing for installing the temperature probe of the energy meter, a by-pass valve, a static balancing valve, a thermostatic head to control the temperature, a priority valve for DHW function and a check valve.In place of the brass spacer (Components - Ref. 4) a thermal energy meter can be mounted, by installing the temperature probe in the appropriate housing (Components - Ref. 5). If the flow switch is activated (by a domestic hot water request), the priority valve closes the heating side and gives power to the DHW production side.

Protection and safety systemsWarning.Danger of burns and electric shocks.Access to the satellite should be by suitably qualified and authorised personnel only.

It is important that the access to the satellite is made only by suitably qualified and authorised personnel: the cabinets are provided with key locking.

Controls and maintenanceWarning.The installation should be undertaken by suitably qualified and authorised personnel only.Observe the EU norms and regulations concerning the use (installation, fixing, etc.), the operation, the recalibration and the replacement the meters. Please refer to the assembly instructions supplied with any meter.

Warning.Before connecting the template to the HIU, remove the lock nuts from the threaded connections.

Heating circuit pressurePeriodically inspect the pressure of the heating circuit by using the manometer (Components - Ref. 23): the pressure value must be maintained over 1 bar (pressure values under 1 bar can damage the circulator by cavitation). A pressure switch with 0,8 bar settings is provide to protect the circulator.

Warning.Circulator stops if the pressure is below 0,8 bar due to the pressure switch device. Please, refill the system to restart the circulator.

Provide a filling system for the heating, that is a connection from the domestic side to the heating with a backflow preventer. during filling be aware that the safety valve will activate at 3 bar (Components - Ref. 24). Warning: danger of burns. In order to eliminate the air in the heating circuit, use the air vent (Components - Ref. 1 and Ref. 18).

Safety valvePeriodically operate the manual handwheel of the safety valve (Components - Ref. 24). Be careful the discharge of water may be hot.Warning: danger of burns.

AdjustmentsDomestic hot water temperatureAdjust the temperature of the domestic hot water using the thermostatic mixing valve (Components - Ref. 13). The adjustment has to be made by means of a digital thermometer to put in contact with the outlet water, in this way (factory default 40 °C):• Remove the cap and release the locking nut form the stem.• Using an 8 mm allen key rotate the temperature adjustment stem anticlockwise to increase the mixed water temperature or clockwise to reduce the mixed water temperature.• Once the desired outlet temperature is reached, re-fit the locking nut to the stem to prevent unauthorised adjustment of the valve and replace the cap on the valve body.

HeatingAdjust the heating temperature using the thermostatic head (Components - Ref. 8):

Position 1 2 3 4 5

Temperature [°C] 23 34 45 56 67

Warning.Provide a safety thermostat for the low temperature heating applications.

If you notice that the rating temperature of the heating is higher than the set value, the flow of the primary may be too high and the thermostatic head is not able to close.To balance the heating production functions, you can adjust the static balancing valve (Components - Ref. 7). Finally, it is possible to change the heating power by modifying the circulator speed using the red knob (Components - Ref. 22).

Electrical connections On the top left of the satellite there is an electrical box IP55 (Componenti - Ref. 25) containing a relay for the priority valve controlled by means of the flow switch and the control and supply of the circulator (Components - Ref. 22).
