Solution
Check the CN21/RES1 connections on the PCB or replace the sensor
Check the N22/RES2 connections on the PCB or replace the sensor
Check the CN12/PH connections on the PCB or replace the sensor
Check the CN8/OPT connections on the PCB or replace the sensor
Check the CN7I/OAT connections on the PCB or replace the sensor
Check the CN9/OHT connections on the PCB or replace the sensor
Check the CN30/HP connections on the card or replace the sensor
Check the water flow
Check the water flow switch
Check the valve opening
Check the by-pass
Check the finned coil is not clogged
Water temperature too hot
Incondensable problem after maintenance, empty and evacuate the
cooling circuit
Refridgerant load too high, remove fluid into a liquid bottle
Check the AI/DI03 connections on the card or replace the sensor
Large gas leak, search for the leak with the detector
Air flow too low, check the ventilator rotation speed
Check the Finned Coil is not clogged, clean its surface
Check the AI/DI0 connections on the card or replace the sensor
Lack of water, check the filtration pump operation
Check the stop valve opening
Check the by-pass adjustment
Lack of water, check the filtration pump operation
Check the stop valve opening
Check the by-pass adjustment
Stop the heat pump, empty the condenser risk of freezing
Check the connections (see electrical diagram)
Stop heat pump operation, empty the condenser to avoid freezing,
by default the heat pump starts the filtration pump to avoid icing
over
Stop heat pump operation, empty the condenser to avoid freezing,
by default the heat pump starts the filtration pump and the heat
pump to avoid icing over.
Check free rotation; check CN97/DC connectors; replace the motor
Check the DCFAN/CN97 connector; replace the motor
Stop the heat pump
