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.
