Solution
Verify the CN21/RES1 connectors on
the board and the extension connector
or replace the sensor
Verify the N22/RES2 connectors on the
board and the extension connector or
replace the sensor
Verify the CN12/PH connectors on the
board and the extension connector or
replace the sensor
Verify the CN8/OPT connectors on the
board and the extension connector or
replace the sensor
Verify the CN7/OAT connectors on the
board and the extension connector or
replace the sensor
Verify the CN9/OHT connectors on the
board and the extension connector or
replace the sensor
Verify the CN30/HP connectors 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
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
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
