40 for buildings with thick walls or outer insulation.
20 for buildings of normal building design.
10 for buildings of light building design.
Central setp compensation (6117)
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.
System frost protection (6120)
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.
Save sensors (6200)
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.
Reset to default parameters (6205)
The factory setting of the regulator is written to the regulator.
Caution
The regulator parameters are overwritten. The factory settings are
stored in the regulator.
Activation of prog. no. 6205:
The regulator is reset to factory setting.
