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.
In the event of a power failure, all working conditions (operating mode, setpoint, fan
stage, all control parameter settings) are stored without time limitation.
When power returns, the thermostat reloads this data and continues to work in the
same conditions as before.
For thermostats with auto timer refer to section 4.10.
