reset by the service engineer, the control unit limits the
functions 14 days after the scheduled date.

When connecting a weather-compensated control unit,
no adjustment to the appliance is required. The system
control unit optimises this setting. This service function
activates a simple, weather-compensated controller with
a linear heating curve. Depending on the on/off input, the
heating is switched on or off.
Htg. curve base • 20…90 °C This is only displayed if the controller was activated. This
can be used to set the base point of the heating curve,
which corresponds to a outside temperature of +20 °C.
Htg. curve end • 20...90 °C This is only displayed if the controller was activated. This
can be used to set the end point of the heating curve,
which corresponds to a outside temperature of -10 °C.
Summer mode • 0...16...30 °C This is only displayed if the controller was activated. This
can be used to set the temperature threshold at which
outside temperature the heating system is to switch to
summer mode.
Frost prot. • Off
•On
Frost temp. limit • 0...5…10 °C Temperature value for the system frost protection.
This service function is only available if the frost
protection function was activated. If the outside
temperature does not exceed the frost threshold
temperature, then the heating pump in the heating circuit
switches on.
1) Only available if optional integral diverter valve kit is fitted.
