TROUBLESHOOTING
In case of abnormal operation of the equipment, alphanumeric codes
(ex. Er01) are displayed on the control panel, alternating with the
system return water temperature.
Some alarms are automatically reset, whereas others can only be
manually reset by pressing the UP and DOWN keys (see pages
15 and 36).
AUTOMATIC FAULT RESET
When the alarm cause has been removed, the control panel
automatically returns to normal operating mode..
MANUAL FAULT RESET
When the cause which generated the fault has been removed,
restore operation by simultaneously pressing the “UP” and
“DOWN” keys
FAULT CAUSE SOLUTION
The compressor does
not
start
Supply voltage too low.
Circulating pump faulty or clogged.
Electrical connections not well tightened.
Check
Remote switch coil fault.
Electronic board failure.
Start capacitor failure (single-phase version)
Compressor failure.
Replace the compressor
Phase monitor LED off (three-phase version) Invert two phases
The compressor stops
due to protection device
trip
Excessive delivery pressure (Er01).
Low suction pressure (Er05).
Low flow rate (Er020).
Circulating pump faulty or clogged (Er020).
Check
.
Abnormal flow switch operation.
Compressor motor failure
Replace the component
Insufficient efficiency
High discharge pressure.
Low suction pressure.
Wrong thermostat calibration.
Inappropriate sizing of appliance.
Check
The compressor is noisy
Return of liquid to the compressor.
Inadequate fixation.
