Landlord:
This menu item allows a date to be set for annual service/
maintenance (End date). The service display appears as a
reminder 30 days before the scheduled date. A contact
telephone number (Installer tel. no.) is shown together
with service display. The tenant should call this number to
arrange a suitable maintenance date. A second reminder
appears at the scheduled date. If the service display is not
reset by the service engineer, the control unit limits the
functions 14 days after the scheduled date.
Reduced functions are set at Maint. reminder:

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.
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.
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.
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.
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.
