CODE
POSSIBLE CAUSE CORRECTIVE ACTION
ACTION FOR CANCELLING FAULT
CODE AFTER CORRECTION
High pressure 100000000
Hot water loop temperature too high, above
50°C.
Test the water temperature at the level of the main loop.
Cut the mains power supply for
5 seconds, and then reconnect.
Insufficient water flow or no water flow at the
level of the appliance.
Test the flow from the pump on the main loop.
Faulty pressure differential
Check electrical connections.
Pressure sensor defective, broken wire or
short circuit.
Check the proper connection of the HP sensor.
Low pressure 110000000
Insufficient airflow.
Check proper fan operation. The fault code is automatically cancelled
after correction (***).
The LED stops flashing and the green
light remains on.
Refrigerant leak. Find and repair any leaks on the pipe circuits.
Clogged filters. Clean or replace the filters
Pressure sensor defective, broken wire or
short circuit.
Check the proper connection of the LP sensor and/or
conduct a continuity test.
Too high hydraulic pressure loss due to an
obstruction in the intake duct.
Check the aeraulic network.
Fan thermal
overload
protection
111000000
Clogged filters. Clean the filters. The fault code is automatically cancelled
after correction (***).
The LED stops flashing and the green
light remains on.
Lack of airflow.
Check the pressure losses on the air intake duct.
Broken wire at the level of the adapter board
or bad contact.
Rewire correctly (c.f. appliance wiring diagram)
Defective contact at the level of the phase
controller board.
Check the connections at the level of the phase controller.
Replace if defective.
Intake air temperature outside operating
limits.
Seized or damaged motor. Check current draw. Replace motor if defective.
Low water
temperature
limit
111110000
Hot water loop temperature < 15°C Test the temperature at the level of the main loop. The fault code is automatically cancelled
after correction (***).
The LED stops flashing and the green
light remains on.
Bad connection of sensor to PCB or defective
sensor.
Test the connections.
Insufficient water flow. Test the water flow at the level of the main loop.
High water
temperature
limit
111111000
Hot water loop temperature > 50°C. Test the temperature at the level of the loop. The fault code is automatically cancelled
after correction (***).
Insufficient water flow. Test the water flow at the level of the main loop.
The LED stops flashing and the green
light remains on.
Anti-freeze
protection
111111100
Insufficient airflow. Test fan operation and pressure losses on the air intake
duct network.
The fault code is automatically cancelled
after correction.
Clogged filters. Clean or replace. The LED stops flashing and the green
light remains on.
Refrigerant leak. Find and repair any leaks on the pipe circuits.
Return air temperature too low
Outside operating limits.
Condensate
tray overflow
protection
111111110
Condensate drainage system blocked Clean the condensates tray. The fault code is automatically cancelled
after correction.
Too high aeraulic pressure loss due to an
obstruction in the intake duct.
Test the aeraulic network pressure losses.
Completely clogged filters. Clean or replace the filters. The LED stops flashing and the green
light remains on
The float is not properly connected to the
PCB, broken wire.
Check the connections.
Other Alarms 111111111
ICT, LWT, RT sensor connection problem, tray
overflowing, broken wire or short circuit.
Check the connections at the level of the PCB and/or
check for broken wires.
The fault code is automatically cancelled
after correction.
The LED stops flashing and the green
light remains on.
Cycle inversion valve electrical fault. Check the electrical connections
No alarm - unit
ON
ON
No alarm - unit
OFF
or on STAND-BY
OFF
(**) This case only concerns installations where the valve is fitted on the water loop upstream of the machine.
(***) Lockout if 3 faults within 1 hour. Cut the mains power supply for 5 seconds, and then reconnect.
Note: More than 2 alarm codes can be activated at the same time. Only the last code detected will be visible on
the RCL control module or on the adapter board. After the source of the first alarm code is resolved, the second
code will appear, and so on until all the faults are cancelled and until the LED stops flashing.
