8 Operation
8.1 Setting temperature
The supply air temperature is set manually in 6 steps in the main menu display by choosing the
temperature symbol.
If an electrical or water re-heater is installed the temperature setpoints are:
12.0, 14.5, 17.0, 19.5 and 22.0 °C. Default value: 12.0 °C.
If the re-heater is deactivated, the temperature steps are:
15.0, 16.0, 17.0, 18.0 or 19.0 °C. Default value: 15.0 °C.
Each temperature step is illustrated by increasing the filling of the temperature symbol.
An unfilled temperature symbol is the 6th setpoint and will activate manual summer mode. See chapter 8.3
8.2 Manual setting of fan speed
It is possible, at any time, to manually set the fan speed in the main menu display. By choosing the fan
symbol and confirming it is possible to increase or decrease the fan speed in the 4 steps: Off, Low,
Nom and High.
By doing so, you override the programmed week schedule for the unit until the end of the present time
period in the week program (chapter 6.6).
Note:
The fan can be set to OFF by activating MAN fan stop. See service menu description under functions.
8.3 Manual and automatic summer mode
Manual summer mode occurs if one temperature step lower than the 12 °C step is selected. The
temperature symbol on the main menu is then completely empty.
