The central setpoint lead monitors the heat generator setpoint to the re­
quired central flow temperature. With the setting the maximum corrector is
restricted, even if a larger adaptation should be required.
The heating circuit pump is activated without heat request subject to out­
side temperature. If the outside temperature reaches the lower limit value
of -4°C, the heating circuit pump is activated. The pump is activated every
6 hours for 10 minutes when the outside temperature is between -5°C and
+1.5°C. When the upper limit value of 1.5°C is reached, the pump
switches off.
Sensor modes can be saved under prog. no. 6200. This is done automati­
cally; however, after change of the heating system (removal of a sensor)
the state must be saved again to the sensor terminals.
The factory setting of the regulator is written to the regulator.
