Description Solution
Water inlet sensor fault P01
The sensor is open or has short-circuited.
Check the AI/DI06 connections on the
card or replace the sensor
Water outlet sensor fault P02
Check the AI/DI07 connections on the
card or replace the sensor
Outside temperature sensor fault P04
Check the AI/DI09 connections on the
card or replace the sensor
De-icing sensor fault P05
Check the AI/DI08 connections on the
card or replace the sensor
Compressor aspiration sensor defect P07
Check the AI/DI05 connections on the
card or replace the sensor
6.8 kΩ resistance fault P09
Check the AI/DI11 connections on the
card or replace the sensor
Compressor discharge sensor fault P081
Check the AI/DI12 connections on the
card or replace the sensor
High pressure protection E01 The sensor is open or has short-circuited.
Check the AI/DI04 connections on the
card or replace the sensor
Check the water flow
Check the water flow detector
Check the valve opening
Check the by-pass
Check the evaporator is not clogged
Water temperature too hot
Incondensable problem after
maintenance, empty and evacuate the
cooling circuit
Fluid load too high, remove fluid into a
liquid bottle
Low pressure protection E02 The sensor is open or has short-circuited.
Check the AI/DI03 connections on the
card or replace the sensor
Large coolant leak, search for the leak
with the detector
Air flow too low, check the ventilator
rotation speed
Check the evaporator is not clogged,
clean its surface
Flow sensor fault E03 The sensor is open or has short-circuited.
Check the AI/DI02 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
Input/Output temperature difference
> 13°C
E06 Applicable in Cold mode only
Lack of water, check the filtration pump
operation
Check the stop valve opening
Check the by-pass adjustment
Antifreeze protection Cold mode
E07
Water output temperature < 4°C
Stop the heat pump, empty the
condenser risk of freezing
Communication problem E08
No communication between the parent
electronic card and the Inverter card
Check the connections (see electrical
diagram)
Level 1 antifreeze protection E19
2°< Water temperature < 4°
and Air temperature < 0°
Stop heat pump operation, empty the
condenser to avoid freezing, by default
the heat pump starts the filtration pump
to avoid icing over
Level 2 antifreeze protection E29
Water temperature < 2°
and Air temperature < 0°
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.
Pressure sensor fault PP The sensor is open or short-circuiting
Check the connections see electrical
diagram
