activates a simple, weather-compensated controller with
a linear heating curve. Depending on the on/off input, the
heating is switched on or off.
This is only displayed if the control unit was activated.
This can be used to set the base point of the heating
curve, which corresponds to an outside temperature of
+20 °C.
This is only displayed if the control unit was activated.
This can be used to set the base point of the heating
