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).

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
