This menu enables real-time access to:
- the status of the appliances responding to a demand
(ON / OFF)
- the reading the different information available from the
appliances (temperature, pressure, flow,)
- the register of last 5 faults recorded for each appliance
(date, time, code and description of faults).
- resetting the fault report.

About
This function is used to display the versions of the
various electronic components attached to the
management box.
(*) On entry into the menus installation modification and options
modification, the management box warns that “the system is
shutting down”. “the system is currently stopped" No further
heating control operations are effected. ... Setting will restart
after leaving these menus.
(**) Refer to the system fault codes section to find the description
of the fault code displayed on the screen.
(***) In an installation equipped with a room thermostat, the date
and time are set from the room thermostat.

Cause
Solution
The boiler is not connected to the control unit.
The cable polarity is reversed.
The boiler is off.
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.
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 shorted.
The sensor is defective or not properly connected
to the control unit.
The sensor is shorted.
Pressure sensor failure
The sensor is defective or not properly
connected to the hydraulic module.
021
Pressure too low <0.5 bar
There is a leak in the heating circuit.The venting
was not carried out correctly.
030

thermostat.
031
Failure in communication with the zone 2 room
thermostat.
032
Failure in communication with the zone 3 room
thermostat.
Failure in communication with the wireless
outdoor sensor
Check the sensor’s connections.
Verify that the position and the operation
of the sensor are correct.
Check the sensor’s resistance.
The sensor is defective or not properly
connected to the control unit.
020
036
Check the sensor’s connections.
Verify that the position and the operation
of the sensor are correct.
Check the sensor’s resistance.
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.
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.
