Cause
➩ Sensor short circuit or open circuit
after sensor recognition by
parameter 215 to sensor B10.
➩ Parameter 210 “Flue gas sensor”
set to terminal B10/B7.
➩ Sensor short circuit or open circuit
after sensor recognition by
parameter 215 to “Sensor B10
+B11”
➩ Parameter 210 “Flue gas sensor”
set to “Terminal B9/B7”.
Rectification
➩ Connect calorifier sensor B10.
➩ Call up Top calorifiers in the Info level.
If “❏❏❏“ is displayed, the sensor has a short
circuit. If the display shows “_ _ _”, the sensor is
open circuit. The heating circuits continue to
operate.
➩ Connect sensor to its plug slot 11/12.
➩ Set parameter 210 to “none” or to “terminal
B9/B7”.
➩ Connect calorifier sensor B11.
➩ Call up the Bottom calorifiers in the Info level.
If “❏❏❏“ is displayed, the sensor has a
short circuit. If the display shows “_ _ _”, the
sensor is open circuit. The heating circuits
continue to operate, the sensor B10 is used
as a control value, replace sensor.
➩ Connect sensor to its plug slot 10/12.
➩ Set parameter 210 to “none”.
*The boiler sensor is used as a control value, replace sensor.
