temperature sensor is not connected, the board
temperature of the core modules is displayed.
Flue gas setpoint
Display of the calculated flue gas setpoint.
Boiler control variable
Display of the signal for the combustion controller.
ID fan control

ID fan speed
Display of the current ID fan speed.
Position of the air flap
Display of the current position of the air flap.
Residual oxygen content
Display of the current residual oxygen content.
Calculated boiler setpoint
Display of the current boiler temperature setpoint
depending on the specified hydraulic system.
Calculated return setpoint
Prerequisite: Maintaining outfeed through return feed
mixer
Specifies the calculated setpoint temperature for the
return temperature control.
Return sensor
Prerequisite: Return temperature control with mixing
valve or bypass pump
Display of the current temperature at the boiler return.
Stoker temperature
Display of the current temperature at the stoker sensor.
Boiler sensor 2

Remote switching using a room console
Specifies whether the boiler can be switched on and
switched off using a room console.
Boiler status
Reports the current status of the boiler.
4.5.2 Boiler - Temperatures
Boiler temperature setpoint
The boiler temperature is regulated to this temperature.
T4e setting range: 70 – 90°C
Shutdown if current boiler temperature is higher
than boiler setpoint +
If the boiler temperature setpoint is exceeded by this
value, the boiler follows the shutdown procedure. The
boiler starts up again below the boiler temperature
setpoint.
