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 unit"
-
"8.3 Connections to the indoor unit"
▪
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 dedicated Human Comfort
Interface (BRC1HHDA used as room thermostat).
