6.5.9.2. - Min. solid fuel boiler temperature (SF Tmin)
Minimum temperature in the solid fuel boiler to switch on the pump. If the tem-
perature at the boiler sensor is below this temperature, the relay is disabled.
6.5.9.3. - Temper. difference for solid fuel boiler (Δ T Solid fuel)
Switch on and Switch off condition for the temperature difference between boiler
and storage. Switch on difference Δ T SF. Switch off temperature difference
Δ T SFoff.
6.5.9.4. - Max. storage temperature (SF Tmax)
Maximum temperature in the storage. If this is exceeded, the relay is switched
off.
This determines the sensor used as boiler sensor.
6.5.9.5. - Boiler sensor
This determines the sensor that is used as storage sensor.
6.5.9.6. - Storage sensor
6.5.10. - Error message
The relay is switched on when one or more protective functions are active. This
function can be inverted, so that the relay is always on and switches off when a
protective function is shown.
Collector protection, System protection, Frost protection, Recooling,
Anti-legionella protection, Messages, Collector alarm
6.5.11. - Booster pump
6.5.11.2. - Filling time
Additional pump that fills the system at the start of every solar charge.
Time the pump is switched on
This setting determines the length of time the pump is switched on at the start
of a solar charge.
