4.10 Handling of faults
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”.
The heating output is energized if the current setpoint is not set to “OFF”, the
thermostat is in heating mode and the temperature is below 0 °C.
For all other cases, no output is energized.
The thermostat resumes Comfort mode after the temperature returns to within the
measuring range.
4.11 DIP switches
Use the DIP switches on the rear side of the thermostat to commission the
thermostat's basic application prior to snapping it to the base.
– The application is set via DIP switches 1 … 3.
– The function of the control outputs (2-position or 3-position, DC 0 … 10 V) is set
via DIP switches 4 and 5.
For details concerning connection of peripheral devices and setting of the DIP
switches please refer to the mounting instructions, document M3182 [3].
During startup, the thermostat reloads the control parameter factory settings after
each change of DIP switch setting.
