4.11 Error handling
When the room temperature is outside the measuring range, i.e. above 49 °C or
below 0 °C, the limiting temperatures flash, e.g. “0 °C” or “49 °C”.
Output Y11 is energized if the current setpoint is not set to “OFF”, the controller is
in heating mode and the temperature is below 0 °C. For all other cases, output Y11
is de-energized. The controller resumes Comfort mode after the temperature
returns to within the measuring range.

receiver. The following operations can be carried out remotely:
