▶ Do not install the user interface in wet areas.
▶ Install and commission the heat source and other
accessories in accordance with the relevant instructions.
▶ Never connect the user interface to the 230 V mains.
▶ Before installing the user interface: electrically isolate the
heat source and all other BUS units from the power supply
and secure against unintentional reconnection, making
sure that the power supply is completely disconnected.

Function as room temperature-dependent

controller

The Comfort+ I RF/Stat RF controls the heat source via the
room temperature. The control unit is not suitable for
controlling heat sources from other manufacturers.
Output control
The heat output of the heat source changes according to the
discrepancy between the current and desired room
temperature. This method of control is suitable for a uniform
temperature level, e.g. open-plan house. There are fewer
burner starts and shorter pump runtimes. This control mode
may not be available depending on the connected heat source.
