With system parameters ROOM TEMP 1 and ROOM TEMP 2 you can select the room temperature
for day and setback mode for heating circuits 1 and 2. The lowest temperature that can be set
is 15 °C. You can change the room temperature, if you feel rooms are either too hot or too cold.
The display ROOM TEMP 2 will only be displayed, if the mixer flow sensor is connected. The given
value is useful for calculating the heating circuit flow temperature.
The actual room temperature can also be scanned, as soon as the FE 7 remote control has been
connected and allocated to heating circuit 1.
With parameter VENTILATION, you can adjust the operating modes for ventilation operation.
With parameter DHW TEMP you can allocate a set day and night temperature to the temperature
inside the DHW cylinder.
With parameter TIME/DATE, you can adjust the time and the summer time.
At the factory, summer time is set to begin on the 25 March and to end on the 25 October.
When parameter HOLIDAY PROG is selected, the heat pump system operates in setback mode.
Frost protection is activated for the DHW cylinder.
In parameter PARTY PROG, you can extend the day mode by a few hours.
In parameter INFO TEMP, you can scan the sensor temperatures of the ventilation and heat pump
system, comparing set with actual temperatures.
In parameter HTG CURVE, you can adjust one heating curve respectively for heating circuit 1 and
2. The room temperature will only remain constant, irrespective of the outside temperature, if the
correct heating curve has been selected for the relevant type of building. Selecting the correct
heating curve is therefore vitally important.
In parameter HTG PROG, you can adjust the heating programs for heating circuit 1 and 2.
In parameter DHW and VENTILATION PROG, you can adjust the times for the day and setback
temperatures for DHW heating.
During COMMISSIONING, you need to determine the settings of control level 2 and the system-
specific parameters. These parameters are adjusted at control level 3 by your heating contractor,
access to which is protected by code.
Your contractor needs to check all parameters in sequence, and enter all selected values into the
column (system value) provided in the commissioning report.
