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.
▪ For more information about connecting the electrical wiring to the unit, see:
- "9.2 Connections to the outdoor
- "9.3 Connections to the indoor
▪ For the main zone: the room temperature is controlled by the dedicated Human
Comfort Interface (BRC1HHDA used as room thermostat).
▪ For the additional zone:
- The external thermostat is directly connected to the indoor unit.
- The desired room temperature is set via the external thermostat and the
thermostatic valves of the radiators in each room.
- The heating demand signal from the external thermostat is connected to the
digital input on the indoor unit (X2M/35a and X2M/30). The indoor unit will
only supply the desired additional leaving water temperature when there is an
actual demand.
▪ The user interface integrated in the indoor unit decides the space operation
mode. Mind that the operation mode on each remote controller of the
heat pump convectors must be set to match the indoor unit.
