Description
Declaration of conformity
This device corresponds to the requirements of the
relevant guidelines and standards, if the corresponding
installation regulations and the manufacturer’s instructions
are complied with
Function
The controller enables setting and measuring values to be
entered and displayed for the heating system in the user's
living room. This means that the heating system can be
monitored and optimized constantly. Use of this controller
also enables the room temperature to be regulated and
displayed directly.
!The following information only applies when the
boiler type connected can send and receive the
necessary data on the BUS. Dotted lines, for
example, appear in the display for data which is not
available.

Modifying the set room temperature
In Normal mode, the heating system operates according to
the set room temperature (default, 20°C / 68°F).
Display in normal mode
!Due to inertia of the room temperature, deviations of
+/- 1°C / 2°F to the required room temperature are
normal. During transition from reduced operation
and heating operation, greater deviations are
possible at times.
Use the rotary knob to adjust the set room temperature by
±5°C / 9 °F. The nighttime temperature (economy
temperature) set on the controller is not affected.
Turn clockwise => Warmer (~1°C / 2°F per dot)
Turn counterclockwise => Colder (~1°C / 2°F per dot)
