0020148679_00 - 11/12 - Glow-worm
Cause
The boiler is not connected to the control unit.
The cable polarity is reversed.
The boiler is off .
The sensor is defective or not properly
connected to the control unit management or
hydraulic module.
The sensor is shorted.
The sensor is defective or not properly
connected to the control unit.
The sensor is shorted.
The sensor is defective or not properly
connected to the control unit.
The sensor is shorted.
The sensor is defective or not properly connected
to the control unit.
The sensor is shorted.
The sensor is defective or not properly
connected to the hydraulic module.
There is a leak in the heating circuit.The venting
was not carried out correctly.
Wireless room thermostat:
The room thermostat is too far from the control
unit.
There is a problem with the batteries in room
thermostat.
Wired room thermostat :
The room thermostat is not properly connected
to the control unit.
The wireless outdoor sensor is too far from the
control unit.
INSTALLATION AND SERVICING
Solution
Check that the boiler is connected to the
control unit.
Check the connection's + / - polarity.
Ensure that there is no interruption to the
electricity network and that the boiler is
properly connected and turned on.
Check the sensor's connections.
Verify that the position and the operation
of the sensor are correct.
Check the sensor's resistance.
Check the sensor's connections.
Verify that the position and the operation
of the sensor are correct.
Check the sensor's resistance.
Check the sensor's connections.
Verify that the position and the operation
of the sensor are correct.
Check the sensor's resistance.
Check that there are no leaks.
Drain the heating circuit. Remove air.
Fill the installation.
Wireless room thermostat:
Check the location of the thermostat.
Check that the thermostat's batteries are
installed in their compartment.
Make sure the battery polarity is not
reversed.
Make sure the batteries are not dead.
If so, replace them with new batteries
Wired room thermostat :
Check room thermostat's connections.
Check the location of the outdoor sensor.
Check that the sensor's power supply is
correctly provided by a photovoltaic cell.
The outside sensor has no battery to be
replaced.
