5.8.1 Adjustable Parameters
Adjustable Parameters - Boiler Temperature (visible for service purposes
only)
Parameter Description
Boiler temperature setpoint 80°C Major set point for Boiler Control System. The boiler temperature is
continuously controlled to reach and hold this temperature
Shutdown if current boiler
temperature is higher than
boiler se 5°C
If the boiler temperature exceeds the target value by this parameter
value, the Boiler Control System switches to “Slumber” mode (on-off
control). The combustion will restart if boiler temperature drops
below the target temperature again.
Always switch off at
maximum boiler se 3°C
If the boiler temperature exceeds the maximum target value of 90°C
(194°F) by this parameter, the Boiler Control System switches to
“Slumber” mode (on-off control). To prevent overheat the Thermal
Storage System circulator will be forced to cool the boiler. The
combustion will restart if boiler temperature drops below the target
temperature.
Minimum boiler temperature to
release all pumps 65°C
The circulator is released above this boiler temperature.
(Hysteresis 2°C)
