FAULT CODES
CHILLED WATER TEMPERATURE, OUT OF RANGE
Fault Code: 012, 013, 022, 023
Description
Water Inlet or Outlet Temperature measured by the temperature sensor is outside the authorised range, this
range can vary depending on the presence or not of glycol with the chilled water (factory setting)
TE < set point 3341 (chilled water min set point) or TE > set point 3342 (Hot water max set point)
TS < set point 3341 (chilled water min set point) or TS > set point 3342 (Hot water max set point)
Where
:
TE % Water inlet Temperature (°C)
TS % Water outlet Temperature (°C)
3341 % Minimum chilled water Temperature at evaporator (°C)
3342 % Maximum chilled water Temperature at evaporator (°C)
Action
$ Compressor immediate shutdown
$ A fault signal is shown on the display.
• 012, Outlet water T° too high
• 013, Intlet water T° too low
• 022, Outlet water T° too low
• 023, Intlet water T° too high
$ The remote fault signal is delayed by 6 minutes
Reset
Automatic reset of the fault signal as soon as the chilled water temperatures comes back in the authorized
operating range with a safety offset of 2°C on the chilled water and 5°C on the hot water.
Water
Set point 3341+2°C < TE < set point 3342 -5°C
Set point 3341+2°C < TS < set point 3342 -5°C
Possible causes Solving the problem
Faulty Chilled water inlet or outlet temperature
probes
Replace the probe.
Wiring problem with the probes, disconnect the
sensor.
Check the probe connections.
