9. HEATING
When the Timer option is activated, a timer is indicated in which time frames for the function
can be adjusted. Outside these time frames, the adjusted room temperature is decreased by the
Correction value.
If the heating circuit is in cooling mode, the set room temperature is increased by the Correc-
tion value.
NOTE:
For information on timer adjustment see page 105.
To each room thermostat, an additional output can be allocated. The output switches on when
the temperature falls below the adjusted room temperature. This way, the room in question
can be excluded from the heating circuit via a valve as long as the desired room temperature is
reached.
Backup heating
For the backup heating of the heating circuit, 3 modes are available:
Therm.: In this mode, the set flow temperature is compared to a store reference sensor.
Zone: In this mode, the set flow temperature is compared to 2 store reference sensors. The
switching conditions have to be fulfilled at both reference sensors.
On/Off: In this mode, the backup heating is activated when the heating circuit pump is
switched on for heating.
In the Output submenu, the modes Standard and Demand are available. If Standard is
selected, the output can be adjusted
If Demand is selected, a demand has to be activated and adjusted in the Heating / Shared
rel. menu first. If Adj. values is selected, the Heating / Shared rel. / Demand will open.
In the correction mode Day/Off (see page 154) the heating circuit and the backup heating will
be completely switched off during the night operation. The starting optimisation can be used for
activating the backup heating before the day operation in order to heat the store to a sufficiently
high temperature. The stopping optimisation can be used for deactivating the backup heating
before the start of the night operation.
If Solar off is activated, backup heating is suppressed when an adjusted store is being loaded.
If the Stset option is activated, the backup heating will only be suppressed when the store
temperature exceeds the set store temperature.
If SFB off is activated, backup heating is suppressed when a selected solid fuel boiler is active.
DHW priority
If the parameter DHW priority is activated, the heating circuit will be switched off and the
backup heating be suppressed as long as DHW heating takes place which has previously been
activated in the Heating / Opt. functions menu.
