9. HEATING
Thermal mode
The allocated demand relay switches on when the temperature at the allocated sensor 1 falls
below the adjusted switch-on temperature. If the temperature at the allocated sensor 1 exceeds
the adjusted switch-off temperature, the relay switches off.
Zone mode
In this mode, a further sensor can be selected. The switch-on, or the switch-off conditions
respectively, then have to be fulfilled at both sensors in order for the output to be switched on
or off.
When the Timer option is activated, a timer is indicated in which time frames for the function
can be adjusted.
NOTE:
For information on timer adjustment see page 105.
With the Man. heating option, DHW heating can be activated outside the adjusted time frame
once by means of a switch, if the temperature has fallen below the switch-off value.
With the DHW holid. off option, DHW heating can be deactivated for a phase of absence.
Î In order to adjust the days of absence, press and hold down button ➆ for 5 s.
With the BAS off option, DHW heating can be switched from automatic mode to Off by means
of the operating mode switch.
If Solar off is activated, DHW heating heating is suppressed when an adjusted store is being
loaded.
If the Stset option is activated, DHW heating heating is only suppressed when the store temper-
ature exceeds the set store temperature.
If SFB off is activated, DHW heating is suppressed when a selected solid fuel boiler is active.

This function uses heat from a buffer store to heat the cold water inlet of the DHW store.
The controller monitors the flow rate at the selected flow rate sensor. If a flow rate is detected,
the pump switches on with the starting speed.
