Space heating/cooling
About space operation modes
Depending on your heat pump model, you have to tell the system
which space operation mode to use: heating or cooling.
If a … heat pump
model is installed
Then…
Heating/cooling
The system can heat up and cool down a
space. You have to tell the system which
space operation mode to use.
Heating only
The system can heat up a space, but
NOT cool down a space. You do NOT
have to tell the system which space
operation mode to use.
