4.10 Handling of faults
When the room temperature is outside the measuring range, i.e. above
49 °C (120 °F) or below 0 °C (32 °F), the limiting temperatures blink,
e.g. "0 °C (32 °F)" or "49 °C (120 °F)".
The heating output is activated if the current setpoint is not set to "OFF", the
thermostat is in heating mode and the temperature is below 0 °C (32 °F).
For all other cases, no output is activated.
The thermostat resumes Comfort mode after the temperature returns to within the
measuring range.
4.11 DIP switches
Use the DIP switches at the rear 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, refer to Mounting Instructions M3182 [3].
During startup, the thermostat reloads the control parameter factory settings after
each change of DIP switch setting.
