Installation

The detailed system schematics for mounting the hydraulic
assemblies and the associated control devices can be found in

Installation location

This user interface is intended only for wall-
mounted installation. Do not install in the heat
source.
The room in your home where the controller is installed is the
reference room. If room temperature-dependent control is
active, the room temperature in this room serves as the
reference variable for the entire system. If the outdoor reset
control is enabled to factor in the room temperature, the room
temperature functions as an additional reference variable.
The control quality depends on the installation location.
