FAULT
LED LARM CODE POSSIBLE CAUSE
CORRECTIVE ACTION
ACTION FOR CANCELLING FAULT CODE
AFTER CORRECTION
High pressure or
water flow fault
100000000
1 flashe
Insufficient airflow
Check proper fan operation.
Cut the mains power supply for
5 seconds, and then reconnect.
Clogged filters.
Clean or replace the filters.
Too high aeraulic pressure loss due to an
obstruction in the intake duct.
Test the aeraulic network.
Insufficient water flow or no water flow at
the level of the appliance.
Test the flow from the pump on the main loop.
Stop cock or water inlet valve shut (**)
Test the valve electrical supply. Test the direction of
flow. Open the valve.
Faulty pressure differential
Check electrical connections.
Pressostat defective, broken wire or short
circuit.
Check the proper connection of the HP pressostat and/or
conduct a continuity test.
Low pressure
110000000
2 flashes
Insufficient water flow in the appliance.
Test the pump flow 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.
Pressostat sensor defective, broken wire
or short circuit.
Check the proper connection of the LP pressostat and/or
conduct a continuity test.
Refrigerant leak.
Find and repair any leaks on the pipe circuits.
Water inlet valve closed (**)
Test the valve electrical supply. Test the direction of
flow.
Low water
temperature limit
111110000
5 flashes
Hot water loop temperature < 13°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.
Insufficient water flow.
Test the water flow at the level of the main loop.
High water
temperature limit
111111000
6 flashes
Hot water loop temperature > 35°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.
Insufficient water flow.
Test the water flow at the level of the main loop.
(**)
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 STORM2 circuit 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.
Example:
111 000 000
²
1 corresponds to one flash of the LED situated on the STORM2 circuit board or on the RCL.
²
0 indicates that there is no flash.
In this precise case, there will be 3 flashes, then the flashing will stop for a while (a few seconds), then there
will be 3 further flashes and so on until the fault is cancelled. Then the LED is off in OFF mode, and fixed on
in ON mode.
