6. TROUBLESHOOTING

6.1. Troubleshooting of failures without error code

Problems encountered
HMI off with heat pump powered
up
Error 495 on Ecomod Heat Control
or ECOMOD does not follow the
Ecomod Heat Control instruction
HMI blocked, cannot operate the
ECOMOD in backup mode

6.2. Error codes and diagnostic assistance

When the ECOMOD is at fault, it displays OFF and the alarm light is on. To see the error code, you must use PRG2
twice.
If an automatic reset fault appears, the heat pump restarts at the latest 6 minutes after the error code disappears.
In the event of a manual reset fault, the fault is cleared by powering down the ECOMOD.
Code Description
E x t e r n a l
E000 safety element
triggered
High pressure
E001
alarm
52 / 78
Cause
Power supply phase reversal
No bus dialogue between heat pump
and Controller regulations
ECOMOD in Controller slave mode
Cause
Remote activation of
the ON/OFF input, input
open
The pressure sensor
detects a pressure that
is higher than the "high
pressure setpoint" (46
bar).
It is reset when the
pressure drops back
down below 36 bar.
If the alarm occurs more
than 3 times in an hour,
it needs to be reset
manually.
Solution
Reverse the cabling between 2 power
supply phases
Power up the heat pump.
Pair Ecomod
ECOMOD: leave the Ecomod Heat
Control
ECOMOD power supply on / off for a few
seconds.
Cancel the Ecomod Heat Control and
ECOMOD pairing: power down the Ecomod
Heat Control or disconnect the communication
bus between the 2 then switch the ECOMOD
on / off for a few seconds.
Solution
• Close the digital input XC1.1/XC1.2
• Check if an alarm occurs even when the mode is
changed, by checking the operation of the 4 way
valve.
• Check that the position of the unit respects the
minimum distances.
• Check the electronic expansion valve EEV is
operating and attached correctly.
• Check the correct operation of the fan; if it is not
working, check for the presence of the three-phase
supply terminals L1F1, L2F1 and L3F1 and of the
fuses included in the terminal blocks. Check the correct
connection and polarity between the E1-GND fan
terminals and XC-13.1 / XC-13.2.
• Check for the presence of the D1-DCOut shunt
