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)
