INFORMATION
A pressure regulating valve should be implemented before the mixing valve station.
This is to guarantee the correct water flow balance between the main leaving water
temperature zone and the additional leaving water temperature zone in relation to
the required capacity of both water temperature zones.
▪
A bypass valve must be installed to make water recirculation possible when all
shut-off valves are closed. To guarantee reliable operation, provide a minimum
water flow as described in table "To check the water volume and flow rate" in
71].
▪
For the additional zone:
-
The heat pump convectors are directly connected to the outdoor unit – or to
the backup heater, if there is one
-
The desired room temperature is set via the controller of the heat pump
convectors. There are different controllers and setups possible for the heat
pump convectors. For more information, see:
The installation manual of the heat pump convectors
The installation manual of the heat pump convector options
The addendum book for optional equipment
-
The heating or cooling demand signals of each heat pump convector are
connected in parallel to the digital input on the outdoor unit (X2M/35a and
X2M/30). The outdoor unit will only supply the desired additional leaving water
temperature when there is an actual demand.
