Glossary of used terms and conceptions

- ALTERNATIVE SOURCE: The heat source is used for systems with solar collectors, masonry

heaters and wood stoves when we either do not have a heat source on hand at any moment or an automatic switch through the signal from the controller of the device (i.e. in a wood stove) is not possible.

- AUXILIARY EXTERNAL SOURCE: The heat source (i.e. oil/gas/pellet/external heater furnace) that

can be used with the device alternately-for example, for the controller of the device, the signal is alternately transmitted by the automatic switch. In case of device malfunctioning(in the anti-freeze programme), the alternative source can take over the task of heating for a short time.

- ADDITIONAL SOURCE or Backup source: The electric flow heater installed in the device and turns

on in the case of device malfunctioning (in the antifreeze program). This ensures temporary operation for bridging the time until an authorized person from the service company arrives to correct the error. The additional source can also be used for bivalent heating operation. This means that in case the heat pump no longer has the heating capacity that could cover the heat losses of the building (very low ambient temperatures), the electrical heater turns on to provide additional heat. Both heat sources work in bivalent parallel operation.

- HEATING WATER: The liquid which flows inside the heating system (pipelines, floor, wall and

radiator heating).

- DHW: The water intended for sanitary use (cleaning, showering, washing ...).

- HEAT PUMP (HP): The device which takes energy from the environment and supplied mechanical

work and adds warmth to heating and DHW. In the text below the term ‘device’ will be used for the heat pump.

- AW: The device takes heat from the air.

- Parameter NORMAL: The desired temperature of heating in the Normal mode of operation.

- Parameter ECO: Lowering the desired temperature in the Eco mode of operation.

- Parameter COMFORT: Raising the desired temperature in the Comfort mode of operation.

Quick settings

NOTE

The parameters of the TERMOTRONIC controller were set according to project documentation of the heating/cooling system, recommendations of the manufacturer for the device and your requests by the authorized contractor. At handover, the contractor practically demonstrates operation of the product and the important setting modes for each of the parameters.

The basic function of the device is switching ON the heating and DHW. The controller of the device calculates the optimal required temperature of the hot water to achieve the desired air temperature of the room by using information about the winter/summer operating mode, the chosen heating/cooling and according to the external temperature.

Setting the temperature of heating/cooling

The temperature in the heated/cooled room is controlled in two stages, by setting the temperature:

1. of the room with the spatial corrector or thermostat and

2. the heating/cooling water in the accumulator and heating/cooling circuits on the controller TERMOTRONIC.

NOTE

In a scenario where the heating/cooling circuit has been operated for a lengthy period of time (For example, floor heating has been operated for 4 days at a stretch); but the desired temperature has not yet been achieved, check the temperature settings of the water that is heated. This could occur in spite of the change in setting of the temperature via a spatial corrector or thermostat.

16 Air-to-Water Heat Pump

Quick settings

NOTE

- The space corrector influences the whole heating circuit and not the temperature of the individual

room. The desired room temperature where the spatial corrector is located in the reference temperature for all other rooms of the heating circuit controlled by this spatial corrector. This is why it must be located in a room where the desired temperature is as close to the desired average temperature of the other rooms (halls, living room). It must not be located close to heat sources (fireplace, TV, direct sunlight, etc.). Before raising the temperature of heated water or the desired room temperature on the spatial corrector make sure the valves on the heat sources in the room where it is too cold for you, are completely or sufficiently opened. If the temperature of other rooms is too high or too low it is necessary to sufficiently open or close the heat sources in the rooms where the deviations from the desired temperature take place.

- For maintaining the correct operation of the heating system you have to choose a suitable

operating mode - winter (heating and DHW) or summer (DHW and cooling - only in certain models).

ENGLISH

Owner’s Manual 17

Quick settings

• Setting the room temperature with a room thermostat

For setting the room temperature with a room thermostat, read the manual that comes with the product or consult the installer.

NOTE

- In case the thermostat is turned on all this time and the heating system does not heat/cool the space to the desired temperature, check the settings of temperatures of the heating system on the device.

- For choosing the function of heating or cooling an appropriate thermostat has to be installed which allows both the functions.

- For maintaining the correct operation of the heating system, you have to choose a suitable operating mode - winter (heating and DHW) or summer (DHW and cooling - only in certain models).

Setting the temperature of heated water

Upon start-up, the control of the hot water temperature was set to Heating mode which ensures the most energy efficient operation for the device. In case, the automatically calculated temperature of the heated water (in accordance with the external temperature) is inadequately heated, the temperature of the heated water can quickly be raised or lowered by changing the parameter of cooler/hotter (C/W).

The values of the parameter C/W are customisable. 1. Circuit 2. Circuit 3. Circuit or 4. Circuit depending on which temperature you want to change.

Quick settings

For advanced changing the temperature of the heated water control mode of the heating system refer to the Chapter(Heating setting).

NOTE

- The temperature of heated water can be raised or lowered for no more than four temperature steps.

- The heating and individual circuits settings are separated from the cooling, this is why all settings for heating remain unchanged with the change of the mode into cooling. The same is true for parameter settings in the menu Cooling, 1. Circuit, 2. Circuit, 3. Circuit, 4. Circuit and Heating, which are separated so as to maintain all settings when changing the heating Mode (winter/summer).

- For heating curve you can choose various temperature modes of operation with setting daily and weekly schedules.

- In case of radiator heating for a significant change, change the parameter C/W for 2 or 3 temperature steps at once but only for 1 temperature step in case of floor heating. Please note that the responsiveness of the heating system in the case of radiator heating is quicker than in the case of floor heating. By changing the parameter C/W several hours can pass (in the case of floor heating) before the heating system responds properly and you can feel the change of the adjustment.

Changing the operational mode - winter/summer mode

The mode of operation - winter or summer, is chosen according to season. When you prefer to have cool air indoors, switch to the summer operating mode. When you prefer warm air indoors, switch to the winter mode. The choice can be automatic or manual.

NOTE

- If you do not operate the summer mode during summer season, this can result in higher energy consumption. The operational costs will be increased for two reasons:

▶ The main circulation pump will switch on from time to time to check whether the need for

heating has arisen.

▶ The additional source could also be turned on (for the protection of the heating system) if the

temperature falls below a certain point (18 °C depending on the start-up settings).

Switching on the additional heat source

In case the heating capacity of the device is not sufficient for covering thermal losses of the building under given weather conditions, you can increase the capacity by switching on the Additional source.

The device has a Backup source, a flow electric water heater fitted as standard which can function as an additional heat source by activating the parameter Additional source. Basically, the controller is set to activate the additional source which operates parallel to the device if the external air temperature falls below -5 °C. This setting is set according to the building at commissioning and can be changed later. Before setting the parameter, we advise consulting the contractor for commissioning.

NOTE

In case you would like to use an oil/gas/pellet furnace or external electric heater as auxiliary heat source, you have to ask the contractor for commissions to perform the setting.

Heating settings

NOTE

While setting, or changing the desired temperature of the heated water ensure that in case when the contractor for commissioning, set the parameter (371) Buff.tank to constant (noted in chapter

11) the values set as Normal and Correction in the menus Heating have to be higher than the

setting of desired values in the mixing circuits (1. Circuit, 2. Circuit, 3. Circuit, and 4. Circuit) if they are active.

• Heating water control mode

The controller of the device enables two ways of controlling the temperature of heated water at the exit of the device or the entry into individual heating circuits:

a) Heating Curve: Setting the desired temperature of heated water according to the external

temperature.

b) Constant: The temperature of heating water is kept constant regardless of the external

temperature.

ENGLISH

The control mode of the heating water suitable for individual buildings depends on various factors such as the type of building, its size, make of the heater ...; this is why the control mode for heating water temperature is set by a Commissioning Engineer. Nevertheless, you can change the setting later. For a comfortable environment, it is recommended to set the default control mode as Heating Curve the setting set at commission. Heating curve means a more effective operation of the heating system because by raising external temperature the desired temperature of heated water is lowered.

• Weather controlled heating

ENGLISH

Weather controlled heating means water temperature in the heater is adjusted to the current air temperature. The lower the external temperature, the higher the heat loss and as a result a higher temperature of water is required for the heating bodies (floor, wall or radiator heating...) to compensate for the loss in heat. The opposite is true in case of higher external temperatures. In this case the heat losses are lower and a low temperature is required to compensate for the losses. The weather controlled heating curve shows that the value for 'Return' depends on the temperature of air outside the building. The lower the external air temperature, the higher the calculated needed value for 'Return'.

In weather controlled heating you can set two parameters:

- Normal: With this parameter, you set the desired value for the parameter 'Return' while the external temperature is -18 ℃

- Correction: With this parameter you can set the heating curve temperature while the external temperature is 15 ℃. It is mainly important for transitional periods because the weather controlled heating curve temperature can be too low at this time, depending on the building and desired comfort.

The parameters Normal, Standby and Correction can be changed to the desired values using the keys or .

Operating mode

The controller of the device enables heating of the heating water/ cooling of the cooling water, heating/cooling of the circuits and DHW in four different operational modes:

► Normal applies to heating/cooling. ► DHW applies to the heating of DHW. ► ECO. ► COMFORT.

These different ways of operation can later be used for setting timetables. The parameter ECO is used for the economic feasibility which implies lowering/raising the desired temperature as set for the heating/cooling mode respectively. The parameter COMFORT is used for the operation which means greater comfort by raising/lowering the temperature of water that has been set for the heating/cooling mode respectively. In case you want to change the entire system to ECO or COMFORT, you can intend to change the mode of operation from AUTO to Operation ECO or Operation COMFORT.

Setting the cooling system

You turn on the cooling mode by entering the menu mode and changing the parameter mode Winter to mode Summer.

- To turn on the cooling according to schedule you have to set the operating schedule for cooling in the menu Cooling. The display and settings of the Cooling menu are enabled only if the conditions of the mode’s operation listed in the Section(Changing the operational mode-winter/summer mode) are met (chosen mode + reversible heat pump).

• Active cooling

Cooling can be set for every parameter described in the table below separately.

In case of active cooling we recommend the following cooling settings:

Schedules

• Operating mode

Every function (heating, cooling, 1. Circuit, 2. Circuit, 3. Circuit, 4. Circuit, DHW, pool, silent operation and circulation) can operate in several ways. Setting the operation mode for individual functions are performed in the schedule for this function. In heating, cooling, mixing circuits, heating of DHW and swimming pool heating there can be 4 different types of operation:

- OFF: Heating/cooling is disabled.

- HEA of COL: Operation in the heating or cooling mode (parameter Normal).

- ECO: In this mode the controller maintains the temperature which is lower by the value of the ECO parameter than the set temperature in the parameter Normal. In case of cooling the temperature set in this mode is higher by the value of the ECO parameter than the set temperature in the parameter Normal. In this mode operation is more economical.

- COM: In this mode the controller maintains the temperature which is higher by the value of the COM parameter than the set temperature in the parameter Normal. In case of cooling the temperature set in this mode is lower by the value of the COM parameter than the set temperature in the parameter Normal. In this mode operation is less economical, depending on the setting it can also be more comfortable.

In circulation of DHW two operation settings are possible:

- OFF: Circulation pump is disabled.

- CIR: Circulation pump is truned on.

These units enable two additional operation modes set in the menu Mode with the parameter Silent mode

- NRM: Normal operation in the heating or cooling mode.

Alternative source

NOTE

For this function and to display the menu Alternative source on the TERMOTRONIC controller you need the extension regulation with the input-output module TT3003.

The alternative source function uses the heat from the solar collectors (SSE) or for using heat from the biomass DHWs. Settings related to this function can be set in the Alternative Source menu. Heating the DHW initiates when temperature of the alternative source reaches the value for parameter Dif.Min. Heating the DHW continues until the SetTemp. value is reached. When heating initiates, the setting of the parameter Prior.DHW is enabled. When the Set.Temp has been reached, the buffer tank starts heating. After the water attains the maximum temperature in the buffer tank, the heating of the DHW resumes until it reaches the Set.Temp. However, if the temperature of the alternative source is higher than that of the buffer tank, the heating continues until it reaches the Max.Temp. When the buffer tank and DHW reach the maximal temperature, heating with the alternative source stops. In case the temperature of the alternative source reaches the temperature of protection (parameter protection), a signal turns on which can control the users to lower the temperature of the alternative source.

Programme for drying screeds

The controller has a built in function of gradual drying of screeds which is especially important for new buildings and before installing flooring. Before using the programme for drying screeds you have to consult the contractor for screeds. According to his requirements you can use the standard programme or adjust it. The programme for drying screeds is located in the menu mode.

• Standard programme

This programme consists of 8 steps and is normally adjusted for all systems of floor heating. Before activating this programme you have to set the maximal allowed temperature of the return water, i.e. 30 °C.

Steps 1-4: Heating Step 5: Maintaining the reached temperature Steps 6-8: Cooling

Steps 1 to 4 perform the heating operation which last 24 hours each (parameter 'Step') totaling up to 96 hours. The value that has been set for the parameter ‘Maximal’ can be attained in 4 steps provided the initial temperature for each step is set at 20 °C (parameter ‘Initial’). If the temperature of each step reaches the Maximal value before the time limit of 24 hours, the device maintains this temperature for the remaining time. In Step 5, the value for the parameter 'Maximal' is maintained for additional 264 hours (parameter Duration). After this time, the remaining steps can be performed. Steps 6 to 8 perform the cooling operation exactly in the reverse direction of the Heating operation. Each step lasts 24 hours totaling up to 72 hours. During this time, the temperature of the return water decreases from the set Max.Temp of 20 °C (parameter Final).

Example:

The maximal temperature of return water is 30 °C. Steps 1 to 4: 20/23,3/26,6/30 °C – in 96 hours Step 5: 30 °C - constant temperature for 264 hours Steps 6 to 8: 26,6/23,3/20 °C – in 96 hours

PV signal

The PV signal can be turned on in the menu mode with the parameter D8-PV. It allows factory and user settings:

- The factory control setting enables the control of the temperature operating mode. This means that in the case of the winter mode (heating) you can turn on cooling. The parameter is set to D8-PV Cooling. It is most often used in combination with photovoltaic systems.

- The user control setting with parameters D8-PV Rise 1, 2, 3 ... enables the parameters listed below to raise various operating modes and with it to change the temperature of the mode:

a) Rise 1: Comfort mode for the buffer tank. b) Rise 2: Comfort mode for the DHW. c) Rise 3: Comfort mode for the circuits. d) Rise 4: Comfort mode for the buffer tank and circuits. e) Rise 5: Comfort mode for the DHW and circuits. f) Rise 6: Comfort mode for the buffer tank and DHW. g) Rise 7: Comfort mode for the buffer tank, DHW and circuits.

Silent operation mode

Devices enable two additional operation modes set in the menu Mode with the parameter Silent mode: The setting NRM switches the mode of operation into normal heating or cooling mode. The setting LOW lowers the parameters of power and noise of the device in the heating or cooling mode. The time and day of operation for these two parameters can be adjusted in a similar manner as the schedule. The lowered frequency of operation of the device means that the compressor and ventilators will operate with a lower power .Consequently, this results in operating the device with a low noise and less power consumption.

In the menu mode use the key to choose

the parameter Silent mode. When the symbols > < appear next to the parameter Silent mode, press the key (ENTER).
