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:
-
"8.2 Connections to the outdoor
-
"8.3 Connections to the indoor
▪
For the main zone:
-
A mixing valve station is installed before the underfloor heating.
-
The pump of the mixing valve station is controlled by the ON/OFF signal on the
indoor unit (X2M/29 and X2M/21; normally closed shut-off valve output).
-
The room temperature is controlled by the user interface, which is used as
room thermostat (EKRUDAL1).
▪
For the additional zone:
-
The heat pump convectors are directly connected to the indoor unit.
-
The desired room temperature is set via the remote controller of the
heat pump convectors for each room.
-
The heating or cooling demand signals of each heat pump convector are
connected in parallel to the digital input on the indoor unit (X2M/35 and
X2M/30). The indoor unit will only supply the desired additional leaving water
temperature when there is an actual demand.
▪
The user interface connected to 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.
