▪ For more information about connecting the electrical wiring to the unit, see:
- "9.2Connections to the outdoor unit"[4105]
- "9.3Connections to the indoor unit"[4108]
▪ For the main zone:
- The room temperature is controlled by the dedicated Human Comfort
Interface (BRC1HHDA used as room thermostat).
- In cooling mode, you can allow the underfloor heating (main zone) to provide
refreshment (no real cooling), or NOT allow it.
If allowed:
Do NOT install a shut-off valve.
Set [F-0C]=0 to activate the setpoint screen of [2] Main zone and [1] Room.
Set the leaving water temperature of the main zone NOT too low (typically:
20°C)
If NOT allowed:
Install a shut-off valve (field supply) and connect it to:
- X2M/21+28 for a normally open valve, OR
- X2M/21+29 for a normally closed valve
In this case, the main zone cooling setpoint will NOT be adjustable. The cooling
setpoint for the heat pump convectors can be adjusted via the additional zone
setpoint screen.
