ACCURATE AX* - AW*
See the controller manual.
The parameter settings on the
microprocessor controller are not correct.
Check that the heater thermal cutout is armed.
Check the power supply to the electric heaters.
If the heater safety thermostat is activated,
resolve the causes and reset the alarm.
The power of the heaters is not sufficient or
the heaters aren't working.
Check the flow-rate and the temperature of
the water hot.
Check the operation of the control valve
and the servomotor.
The hot water coil isn't working correctly.
Check the operation of the hot gas three-way
valve;
Check the operation of the compressor used
for post-heating: in this case, see “THE
COMPRESSOR/COMPRESSORS DON'T
START”.
The hot gas post-heating system isn't working
during the dehumidification plus post-heating
phase
Close the valve using the manual control knob
and replace the servomotor. The three-way valve in the chilled water
circuit is stuck in the open position.
ROOM TEMPERATURE
TOO LOW
FAULT CAUSE SOLUTION
See the controller manual.
The parameter settings on the
microprocessor controller are not correct.
Check and calculate the latent load; check the
flow-rate and the conditions of the outside air;
check the inflow of outside air.
Latent load higher than expected
See “THE COMPRESSOR/COMPRESSORS
DON'T START”. The compressor isn't working during the
dehumidification phase.
Check the operation of the solenoid valve that
controls the dehumidification circuit.
The dehumidification valve doesn't close.
See the controller manual; check the
operation of the panel and/or the probe.
The control system isn't working.
Lower the chilled water temperature until
there is condensation on the surface of the
coil
The chilled water is not cold enough to
dehumidify (energy saving and twin cool units)
AMBIENT HUMIDITY
TOO HIGH
