5.6 Space heating/cooling control
5.6.1 About space heating/cooling control
Controlling space heating/cooling typically consists of the following stages:
1 Setting the space operation mode
2 Controlling the temperature
Depending on the system layout and installer configuration, you use a different
temperature control:
▪ Room thermostat control
▪ Leaving water temperature control
▪ External room thermostat control
5.6.2 Setting the space operation mode
About space operation modes
Your unit is a heating only model. The system can heat up a space, but NOT cool
down a space.
However, if the kit EKHVCONV* is installed, the system can cool down a space, and
you have to tell the system which space operation mode to use: heating or cooling.
To determine if a heating/cooling heat pump model is installed
1 Go to [4]: Space heating/cooling.
2 Check if [4.1] Operation mode is listed and editable. If so, a
heating/cooling heat pump model is installed.
