4.4 Space heating/cooling control
4.4.1 About space heating/cooling control
Controlling space heating/cooling typically consists of the following stages:
1Setting the space operation mode
2Controlling 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
4.4.2 Setting the space operation mode
About space operation modes
Your unit can be a heating or a heating/cooling model:
▪If your unit is a heating model, it can heat up a space.
▪If your unit is a heating/cooling model, it can both heat up and cool down a
space. You have to tell the system which operation mode to use.
To determine if a heating/cooling heat pump model is installed
1Go to [4]: Space heating/cooling.
2Check if [4.1] Operation mode is listed and editable. If so, a
heating/cooling heat pump model is installed.
