The boiler is off.
The heat pump is not connected to the
control unit.
The heat pump is off.
The hydraulic module is not connected to
the control unit.
The hydraulic module 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 hydraulic module.
There is a leak in the heating circuit.The
degassing was not carried out correctly.
The room thermostat is too far from the
control unit.
There is a problem with the batteries in
room thermostat.

from the control unit.
MAINTENANCE
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.
Make sure the heat pump is connected to
the control unit.
Ensure that there is no interruption to the
electricity network and that the heat pump
is properly connected and turned on.
Make sure that the hydraulic module is
connected to the control unit.
Ensure that there is no interruption to the
electricity network and that the hydraulic
module 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.
Check the RF signal quality via the
Climapro RF installer menu.
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
Check the location of the outdoor sensor.
Check that the sensor's power supply is
correctly provided by a photovoltaic cell.
