Gebwell Qi Installation, operation, and maintenance manual
Sensor Description
The controller cannot detect the
extra module 2 from the
channel.
The battery on the controller's
operating monitor is running
out.
A maintenance notice is
programmed on the controller.
The incoming temperature from
the collector is lower than set in
the menu. The controller will
restore the situation
automatically in 4 hours.
Alarm goes off, when hot gas
sensor shows 130°C. 3 alarms
per 8 hours are allowed with
automatic restoring.
The heat pump has not been able
to maintain the requested
temperature in the legionella
function. The controller will
retry charging after minimum
idle time.
The electrical resistor's
overheating protector has
tripped.
High pressure switch has
E10
tripped.
High pressure switch has tripped
E10 in connection with the start-up
of heating.
