Cooling with a separate cooling circuit

If a separate cooling circuit (e.g. for cooling a wine cellar) has been installed in your
system, you can adjust the room temperature and the cooling characteristics. The
cooling circuit is regulated via a room temperature sensor. We recommend the use
of an NC or AC-Box (accessories).
