1. GRAMMER TWINSOLAR – TOPSOLAR

Heating and ventilation by means of solar energy GRAMMER TWINSOLAR is a mains-independent air collector system for heating and ventilating by means of solar energy.

Because air is the heat transfer medium, TWINSOLAR is safe in operation and almost maintenance-free.

GRAMMER TOPSOLAR the mains-operated alternative – a collector system similar to TWINSOLAR but without a photo-voltaic module.

The photo-voltaic panel integrated in the collector ensures mains-independent operation of the system.

With TWINSOLAR you will receive tried-and-tested collector technology based on 30 years of experience in the production of air collectors.

1.1. What is the performance of a Grammer TwinSolar and

TopSolar panels

Even when the solar radiation is low – i.e. when the sky is cloudy – GRAMMER TWINSOLAR starts working and conveys fresh, warm air into the building. During maximum solar radiation the temperature increase can be up to 40 degrees with a power output of 700 W/m². The maximum radiation intensity from the sun is – regardless of the time of year – 1000 Watt per m² collector surface. This peak power is observed particularly during cold and clear winter days . 70 % of this received solar energy is transformed into thermal energy by TWINSOLAR and delivered to the building. The collector capacities and increase in temperature provided also apply to TOPSOLAR. .

TWINSOLAR MANUAL 5

S O L A R

Dimensioning – optimum collector size

The required size of TWINSOLAR and TopSolar systems depends principally on the room area to be heated.

For the dimensioning of the collector size, the diagram below provides reference values.

Collector dimensioning – reference value for a building with medium insulation standard

10 – 20 m² living area <-> 1 m² air collector

Notes:

- In the case of buildings with a good insulation standard or for installations in southern Europe 1 m² of collector area can heat and ventilate a living area of up to 20 m².

- The reference values refer to an average room height of 2.5 m.

- For permanently used buildings (e.g. dwelling houses) the simulation program Luftikuss can carry out a dimensioning computation providing information about the achievable energy saving. A Luftikuss demo-version is available at www.grammer-solar.de in the Login-area.

1.4.2 Reirculating air version

As standard, TWINSOLAR and TOPSOLAR arrangements are provided for so-called "fresh-air operation". This means that fresh outside air is sucked in via an air filter integrated into the collector.

Optional recirculating air operation As an alternative to the fresh-air operation, the collector can also be fed with room air from the building or with fresh air via an external filter box (always plan it). This can be sensible in the case of the following applications:

1) Pure heating operation, no ventilation necessary. Room air from the building is warmed in the collector can then returned to the room.

2) Comfortable filter replacement in the loft. Instead of the more difficult filter

replacement on top of the roof, the filter maintenance of an external filter box could be carried out easily in the loft.

1.4.3 Air distribution system – planning information

Use spiral tubes made from galvanised steel plate of dimensions 125 mm and 160 mm

Plastic tubes should not be used (evaporation, odour problems)

A non-return valve must always be installed in the tube between the collector and the room.

With TWINSOLAR 1.3 and 2.0 the fan is integrated in the collector. An external radial fan from

TWINSOLAR 4.0 is delivered with the collector package.

In the fresh air tube sound absorbers are to be built-in downstream of the fan (from TWN 4.0).

If two neighbouring rooms are connected by the ventilation system, telephony sound absorbers

are to be installed between them.

All tubes carrying warm air are to be insulated.

Tubes carrying cold air through warm rooms are to be insulated – prevention of condensation!

Keep the tube connection short in order to limit pressure drops and heat loss!

Observe the permissible pressure losses (table chapter 1.2 "Technical data" and the following

1.5 Installation and maintenance information

1.5.1 Important information TWINSOLAR – TOPSOLAR

PV modules of the TWINSOLAR collector must be installed at a location which is never shaded. Even minor shading of the solar modules will result in a massive loss in performance.

The air filter must be replaced at least once or twice a year Air-intake: Do not install the filter collector or air-intake close to a chimney, an exhaust air duct

or near other dangerous or toxic gases. Adequate space is to be provided to allow the air filter to be removed from the collector from the

narrow side Install the fans (external starting with TWINSOLAR 4.0) with insulation against transmission of

vibrations Provide a sound absorber downstream of the fan (see diagram below)

All electrical installations are to be carried out by an electrician in accordance with the VDE guidelines.

All the screw connections on the collector installation kits are to be checked annually for tightness

and, if necessary, tightened up. Integration into the building envelope: The space between the collector and the building envelope

is to back-ventilate, while the masonry is to protect against intruding moisture. Maintenance and repair or replacement of a defective collector pane are only possible if there is about 4 cm surrounding area at the sides of the collector to dismantle the glazing profiles.

Collector orientation

For optimum performance in the northern hemisphere, the collector should always be directed to the south, in the southern hemisphere to the north. However, deviations from the optimal direction of up to 45° only result in a minor reduction in the energy gain.

Because a warm air collector system is mainly used to provide energy during the winter, spring and autumn, and as during these seasons the solar angle is relatively low, the collector should ideally be installed onto frames at a 45° to 60° angle from the horizontal.

In areas where high snowfalls are to be expected, wall-mounting is recommended! 1.5.2 Fan

Commissioning: Only when the air-duct system is connected!

Vibration insulation from the duct system: flexible connection tubes (contained in the scope of

delivery) are to be mounted on the inlet side and the pressure side. See fig. 3

Vibration insulation from the building: Install a hard foam support between the fan support and

the sub–structure as well as rubber washers on the screws!

Noise from the air flow: Always install a muffler downstream of the fans!

Fan installation: Always on the suction side!

Never insulate fans and protect against heat accumulation: Danger of overheating!

Fans are not weather-proof or water-proof!

With TWINSOLAR 1.3 and 2.0 the fan is integrated in the collector (ready for operation).

1.6 Control TWINSOLAR

For the maximum utilisation of solar energy, the operator should note the following:

The solar control automatically controls the operation of the TWINSOLAR systems as a function of

radiation or collector temperature and room temperature.

The desired maximum room temperature is to be set 2 to 3 °C higher at the solar controller than

that set for the conventional heating system. (Preferential setting for solar energy)

Fig. 2: TWINSOLAR 4.0 – 12.5 TWINSOLAR Control PV-operated differential temperature controller (included in the delivery)

POWERUNIT- APW (matching transformer)

The POWERUNIT-APW provides optimal usage of the photo-voltaic modules at different radiation

conditions and guarantees maximum solar gain. From TWINSOLAR 4.0 onwards these electronic

parts are integrated into the socket of the ventilator in standard form.

Fig. 3: PV system with maximum power unit (APW)

Warranty: Never attempt to interfere with the collector technology or electronics yourself, because otherwise the warranty will become void. Should the collector develop a fault during the warranty period, we will repair the collector or deliver a replacement.

1.6.2. Temperature Control TWINSOLAR 1.3 und TWINSOLAR 2.0 – integrated start up switch

The temperature control of all TWINSOLAR Compact collectors consists of the components Start up switch and thermostat control.

Start up switch (pre-essembled in the collector): The thermostat starts the ventilator running, when the collector has reached a temperature of ca. 22°C; if the temperatur is

lower than 17°C, the ventilator turns off.

Thermostat control (included in the delivery): When achiving the adjusted maximum room temperature, the ventilator turns off

TWINSOLAR 2.0 (1.3 from 2011) Compact

TWINSOLAR 4.0, 4.5, 6.0 Compact

Start up switch is accessible by the air outlet

Start up switch is accessible when the collector connection is open

Important informations: • Since September 2010, our TWINSOLAR 2.0-collectors are equipped with an

additional start up switch.

• From midyear 2011, the start up switch will be standard also in the TWIN 1.3 series.

• Optionally, the start up switch can be briged respectively deactivated. In this case, the ventilator runs only depending on the irradiation and also with a collector temperature lower than 22°C. This alternative operating can make sens, if the focus is on the ventilation.

1.6.2. Control TWINSOLAR Modular 4.0 – 12.5

In opposition to the simplified control of TWINSOLAR Compact, the TWINSOLAR Control with integrated differential temperatur control is used.

Function:

TWINSOLAR Control controls and monitors the operation of TWINSOLAR systems. The controller is provided with current by the collector integrated PV-module and works only on sufficient solar radiation. With too weak radiation or at night there will be no signal. The simple control compares the room and collector temperatures and switches the fan on or off depending on the temperature (differential temperature control). Once the desired room temperature has been reached the system will switch off.

Fig. 2 TWINSOLAR Control

Manual operation

With the left-hand button the "manual operation" menu (hand symbol) can be activated or terminated. By means of the right-hand button the fan (only whenthe PV module supplies sufficient power!) can be started up manually. After approx. 8 hours, the next day or on leaving the menu item “manual operation” the control changes again into the automatic modus.

Line operation:

If the ventilator pictogram moves, the system is in operation!

Disable the system: Set max. room temperature to 5°C.

DISPLAY MEASURED VALUES–information menu

In the information menu the following measured values can be displayed by means of the "up" and "down" buttons:

• Current collector temperature • Min. and max collector temperature (current • value) • Storage temperature = room temperature • Min. and max room temperature (current

value)

SETTING – programming

With the left-hand button the "programming" menu can be activated or terminated. With the "Up" and "Down" buttons the following values to be set can be retrieved :

• max (max. room temperature) approx. 23°C • dT max. (switching on difference) 6 K • dT max. (switching on difference) 3 K

The modified values are to be confirmed and saved by pressing the right-hand button. Switching off: set maximum value to the smallest value(5°C) *) Additional remark dT max.: The unit switches on if the collector temperature is 6°C (dTmax=6K) higher than room temperature and runs as long as it is still 3°C (dTmin=3K) higher resp. achieve the max. temperature. For long stretches of pipe (cooling off), the values must be set higher (e.g. 12 or 8K).

Important information: The delivery contains a "Quick info" about the controller in 5 languages. This "Quick info" in the appropriate language should be inserted in the slot provided for this on the back of the controller.

1.8 Collector installation

1.8.1 Installation on inclined roofs

For installation on an inclined roof, individual compact collectors (e.g. TWINSOLAR 2.0) or several SLK-collectors elements are connected by means of roof hooks or supports to the rafters or to the roof structure. The roof structure experiences an additional load from the weight of the collectors. Whether or not a static calculation is required must be decided case by case. The SLK-collectors have a static weight of approx. 22. kg/m². In snowy regions more mounting rails and roof hooks are to be scheduled than included in the standard package! You will obtain information and prices on request.

Installation steps – short overview 1. Measure/determine the collector field on the roof (for collector diagrams see appendix)

2. Measure the location of the roof lead-through (consider location of rafters!) Install the roof lead-through – cut a hole in the roof boarding and fit the lead sheet so that it is rain-proof. Pipe connections at the air connection from the collector to save about sheet metal screws or blind rivets

3. Install the roof hooks. Screw the roof hooks to the rafters. If necessary match heights by the

means of inserted wood boards.

4. Install the installation rails to the roof hooks.

5. Lay the collector sensor cable / PV connection cable and prepare connection.

6. Glue the sealing profile to the collector connections

7. Mount the collectors.

8. Connect the collectors by means of the quick-action clamps.

9. Assemble collector sensor, affiliate PV-connecting cable and check all the screws for secure

attachment. This has to be repeated annually.

Tool list: Open- end wrench M 15, M 17, screwdriver set, measuring tape, marker, hammer, boring machine with screw-element (Torx T40 Bit), electrical handsaw, angle grinder with stone disc (for bricks). Installation steps – comprehensive description 1st step – measure the roof CAD collector diagrams see chapter 3. Do not arrange the air inlet near flues and vents and for filter collectors plan enough room for the change of the filter. 2nd step – roof lead-through and collector connection

The roof lead-through for the collector installation consists of a lead

sheet with a flange collar with sealing profile as well as a tube

connection piece (125 or 160 mm).

The lead sheet is flexible and can be moulded to a wide range of tile shapes.

Important information:

The collectors are to be placed on top of the support triangles and are to be screwed on with the

attachment clamps

In the case of installation on top of flat roofs the system may need to be protected against wind

loads (screw tight, weigh down, clamp down). Under favourable conditions the weight of the

installation will be adequate. For this a wind load calculation has to be carried out

All screw or dowel connections are to be made carefully. Safety in the wind! In the case of a sensible roof cladding (e. g. membrane roof), support feet with underlayed

building-protection mats must be used.

Please also observe the safety information in chapter 1.10 !

1.9 General maintenance information

1.9.1. GRAMMER air collector

The GRAMMER air-base collector does not include any mechanically moving parts and is therefore maintenance free and intrinsically safe.

1.9.2. Checking the fixing of collectors and mounting frames

The collector system on the roof will be properly secured by the installation company. However, it is exposed to movements from wind and gales. A regular checking routine should ensure that all screw connections are tight, in particularly after heavy gales.

1.9.3. Cleaning

According to our experience the cleaning effect of strong rainfall is adequate. In areas with strong environmental contamination or when large amounts of pollen have been released or dry periods last a long time, it may be useful to clean the glass surface with tap water and a sponge or car washing brush.

1.9.4. Air filter

The collectors are protected by the intake air filter in the system of quality class EU 4 against internal contamination. The filters should be replaced after the period customarily used by the company or at the location as described in the general installation instructions, or every 6 months for collectors run on out-of-doors air or mixed air or, in the case of a pure circulating air system, every year before the beginning of the heating period (September)

FILTER REPLACEMENT

1 to 2 x annually 1. Release the tension locks on

the filter cover and take off the cover.

2. Pull out the filter cartridge and replace the filter mat with a new one.

3. Push the filter cartridge back into the collector.

4. Attach the cover using the tension locks.

Hint: During intake of surrounding air the filter in the external filter box must be replaced.

1.9.5. Air as heat transfer medium

Air does not experience phase changes (freezing or boiling) so all safety measures in this respect are not necessary.

However, it cannot be excluded that after a longer period of standstill occasionally condensation will form on the inside of the cover, depending on the air humidity and low outside temperatures. After the system has been restarted this condensation will disappear by itself 1.10. Safety information

1.10.1. Weather

Carry out the installation only when the weather is fair. Particularly for installations integrated into the

roof, it should be observed that no precipitation is falling in order to prevent humidity from entering the

building. If the wind freshens up, you should interrupt the installation in the interests of your own

safety. Also remember that on very hot days with strong solar radiation, there is a risk of burns from

hot metal parts. Under unfavourable conditions temperatures up to 150°C can occur (particularly at the

absorber).

1.10.2. Ladders

Ladders should be leaned at an angle of 65 – 75° to a secure support and they must

reach at least 1 m above the highest point used to step off it. In addition, they

should be secured against sliding, falling over, slipping off and sinking into the

ground. Finally, ladders are only to be used to access points up to a height

difference of 5 m.

1.10.3. Protection from falling objects

Traffic areas and workplaces below have to be protected against objects dropping,

falling, sliding or rolling off. The areas where people are endangered are to be

marked and blocked off.

1.10.4. Protection against falling

From a height of 3 m for work on an inclined roof of more than 20° to 60°,

protection against falling is required (VBG, 37, § 8).

TWINSOLAR MANUAL 33

S O L A R

One option is roof safety scaffolding. The vertical distance

between workplace and safety installation may be no

greater than 5 m. Alternatively, the top scaffolding support

can also be designed as a safety platform.

For roof steeper than 45° inclination special workplaces

must be created (e.g. roofer chairs, roof ladders, wooden

safety structures)

A further option for fall protection for work on inclined roofs

up to 60° are roof safety walls. They are also required from a fall height of 3 m

and the vertical distance between workplace and safety installation may be no

larger than 5 m. Safety walls must be at least 2 m higher than the workplaces

to be protected by them.

If roof safety scaffolding or roof safety walls are inappropriate, safety

harnesses can also be used as fall protection. The safety roof hook should be

preferably attached above the user to load bearing components. Do not use

ladder hooks!

1.10.5. Rules of technology

The installations should correspond to the conditions on site, the local regulations

and, not at least, to the rules of technology. In this context, the following are to be

mentioned in particular:

Installation on roofs

DIN 18338 Roofing,

DIN 18339 Plumbing

Solar air supply system (Standard system)

The solar air supply system is a simple and effective solution to heat and ventilate existing or new buildings with solar energy.

Solar heated fresh or ambient air from the collector flows through a simple pipe system and air outlets into the rooms. In the case of dense building envelopes ventilation openings (e.g. ventilation in toilets, kitchen exhaust hood) are planned.

Solar hot water generation through the solar box with integrated air and water heat exchanger is practical for additional use in summer.

Further system variations:

Domestic solar ventilation

Solar air supply systems can be easily integrated into new or existing domestic ventilation systems. Solar heat flows into the rooms through the air distribution system of the ventilating units. If no solar heat is required for heating the rooms, the solar box produces hot water.

Under floor solar heating

Using the solar energy products offered, air is heated in

a closed system through the collector and then led through walls. The heat energy is emitted to these structural parts in the process, stored in them and emitted to the rooms as a pleasant radiant warmth later on.

Use of the hypocaust is possible without solar radiation using additional heating.

If no solar heat is required for room heating, the solar box produces hot water.

2.3.4. Control TOPSOLAR – Under floor system

Function:

The regulator DeltaSol BS Plus compares the collector temperature TKL with the reference temperature TSP in the hypocaust wall and controls the unit dependant on the set temperatures. When a maximum wall temperature has been reached (adjustable using the room thermostat) the unit switches off. An additional temperature value can be displayed using the temperature sensor TTH (e.g. outside temperature).

Displayed and set values: Please note: Go to “SPR” and change language to “En” for English codes!

Electrical connection:

Please observe the instructions enclosed with the regulator for installation of electrical parts!

If the collector temperature (S1) is higher than the wall temperature(S2) by the difference in temperature set in the regulator, the unit switches to EIN (ON) and the fan conveys heated air to the connected hypocaust till the desired room temperature has been reached. An additional probe can be attached to position (S3) (e.g. for measuring outside temperature).

The fan is operated through an external room thermostat. Once the desired room temperature has been reached, the fan switches off.

2.3.5. Temperature sensors – arrangement/installation

When placing the room temperature probe (Fig.1), the following criteria should be observed:

Do not place in the vicinity of air supply elements

Avoid direct radiation from the sun

Avoid influence of heat from other sources

Fitting the collector probe (Fig.2): The probe (moisten it slightly) must be pushed in at the intended opening at the end collector till it impacts (approx.20 cm). The cable should be attached to the solar regulator.

Probe cable – extension with 2 x 0.75 mm² up to 50 m cable length, otherwise 1,5 mm²

Functional control standard probe type Pt 1000: The resistance value at 20 °C is approx. 1077.

2.4. CHECK LIST –TopSolar ERROR CORRECTION

Problem Possible cause – solution

Solar control is in manual operation set to AUS (OFF) – set to “automatic operation” , see 2.3.2.

Check connecting clamps for contact – fix tightly if necessary Fan does not work

Check ventilation pipes for free cross section

Check probes for contact and appropriate placement

Set temperature difference – could be too large Unit does not run automatically

Check maximum temperature setting – it could be that the value set is too small so that no heating is possible .

Unit runs continuously and in an unregulated manner

Unit is set to ON in operating menu – set to automatic operation, see chapter 2.3.2

Install sound absorber

Install fan with vibration dampening Fan is too loud

Air supply valves could be to intensely throttled – whistling sounds

1 wire control! Terminal connections N, L1 and L2 on the motor and the regulator should be observed. Motor valve is not functioning Check adjustable mechanical impact on the motor .

Fluctuating temperature display

If the probe lines are very long and have been laid next to lines leading to voltage, there can be disturbances. Suggestion: use insulated cables or other cable layouts.

Check filters for dirt. Change filters at least once or twice a year. !!!

Return valve is stuck. Check whether screw fittings are hindering the valve function. Not performing well enough

Pipe system is blocked . Check for free cross section
