Store reference sensor
Ref. sensor store
Reference sensor store loading
Selection: S2, S3
Factory setting: S2
The adjustment channel reference sensor store is used for selecting the sensor to
be used as the reference sensor for store loading.
Maximum store temperature
Tmax store
Maximum store temperature
Adjustment range: 30 ... 95 °C
Factory setting: 90 °C
If the temperature measured at the lower store sensor exceeds the adjusted maxi-
mum store temperature, the controller switches off the SFB / boiler. The store will
no longer be loaded, in order to reduce the risk of scalding and system damage. A
hysteresis for the maximum store temperature can be adjusted in the Installer menu.
Max. sensor
Reference sensor store maximum temperature
Selection: S2, S3
Factory setting: S3
The adjustment channel Max. sensor is used for selecting the sensor to be used as
the reference sensor for the maximum store temperature.
Boiler maximum limitation
Temerg SFB / boiler
Adjustment range: 80 ... 105 °C
Factory setting: 95 °C
∆ Tmax SFB / boiler
Hysteresis SFB / boiler maximum limitation
Adjustment range: 1.0 ... 25.0 K
Factory setting: 5.0 K
In order to limit the fl ow temperature of the SFB / boiler to a maximum value, a
maximum SFB / boiler temperature Temerg SFB / boiler can be adjusted in addition
to the discharge safety device.
If this temperature is reached at sensor S1, the controller switches off the circu-
lating pump.
If the fl ow temperature has exceeded the SFB / boiler maximum temperature and
if the temperature has fallen by the hysteresis ∆Tmax SFB / boiler (adjustable in
the Installer menu) below Temerg / SFB / boiler measured at sensor 1, the
circulating pump switches on again.
