The heat pump system supplies leaving water to heat emitters in one or more
rooms.
Because the system offers a wide flexibility to control the temperature in each
room, you need to answer the following questions first:
▪ How many rooms are heated or cooled by the heat pump system?
▪ Which heat emitter types are used in each room and what is their design leaving
water temperature?
Once the space heating/cooling requirements are clear, we recommend to follow
the setup guidelines below.
NOTICE
If an external room thermostat is used, the external room thermostat will control the
room frost protection. However, the room frost protection is only possible if [C.2]
Space heating/cooling=On.
INFORMATION
In case an external room thermostat is used and room frost protection needs to be
guaranteed in all conditions, then you have to set Emergency [9.5] to Automatic.
NOTICE
An overpressure bypass valve can be integrated in the system. Keep in mind that this
valve might not be shown on the illustrations.
