POSSIBLE CAUSES CORRECTIVE ACTION
The temperature setting is not
correct.
Check the controller setpoint.
The flowstart timer is still running. The unit will start after approx. 15
seconds. Make sure that water is
flowing through the evaporator.
Neither one of the circuits can start
up.
Refer to Symptom 4: One of the
circuits does not start up.
Unit is in manual mode (all
compressors at 0%).
Check on the controller.
Power supply failure. Check the voltage on the supply
panel.
Blown fuse or interrupted protection
device.
Inspect fuses and protection
devices. Replace by fuses of the
same size and type (refer to
"Electrical specifications" on
page 2).
Loose connections. Inspect connections of the field
wiring and the internal wiring of the
unit. Tighten all loose connections.
Shorted or broken wires. Test circuits using a tester and repair
if necessary.
POSSIBLE CAUSES CORRECTIVE ACTION
The remote ON/OFF input is present
and the remote switch is off.
Put the remote switch on or disable
the remote ON/OFF input.
POSSIBLE CAUSES CORRECTIVE ACTION
All circuits are in failure mode. Refer to Symptom 5: One of the
following safety devices is activated.
One of the following safety devices is
activated:
•flowswitch (S8L,S9L)
• Emergency stop
Refer to Symptom 5: One of the
following safety devices is activated.
The ON LED is broken. Contact your local dealer.
POSSIBLE CAUSES CORRECTIVE ACTION
One of the following safety devices is
activated:
• Compressor thermal protector (Q*M)
•Overcurrent relay (K*S)
• Discharge thermal protector (S*T)
•Low pressure
• High pressure switch (S*PH)
•Reverse phase protector (R*P)
•Freeze-up
Check on the controller and refer to
Symptom 5: One of the following
safety devices is activated.
The anti-recycling timer is still active. The circuit can only start up after
approximately 10 minutes.
The guard timer is still active. The circuit can only start up after
approximately 1 minute.
The circuit is limited to 0%. Check the "enable/disable capacity
limitation" remote contact.
Symptom 5.1: Overcurrent relay of compressor
POSSIBLE CAUSES CORRECTIVE ACTION
Failure of one of the phases. Check fuses on the supply panel or
measure the supply voltage.
Voltage too low. Measure the supply voltage.
Overload of motor. Reset. If the failure persists, call your
local dealer.
RESET Push the blue button on the over-
current relay inside the switch box
and reset the controller.
Symptom 5.2: Low pressure
POSSIBLE CAUSES CORRECTIVE ACTION
Water flow to water heat exchanger
too low.
Increase the water flow.
Shortage of refrigerant. Check for leaks and refill refrigerant,
if necessary.
Unit is working out of its operation
range.
Check the operation conditions of
the unit.
Inlet temperature to the water heat
exchanger is too low.
Increase the inlet water temperature.
Dirty evaporator. Clean the evaporator, or call your
local dealer
Low pressure safety setting too high. Refer to the installation manual
“Customization in the service menu”,
paragraph “Setting of the minimum
outlet water temperature” for correct
values.
flowswitch is not working or no water
flow.
Check the flowswitch and the water
pump.
RESET After pressure rise, this safety resets
automatically, but the controller still
needs to be reset.
Symptom 5.3: High-pressure switch
POSSIBLE CAUSES CORRECTIVE ACTION
Water flow to condenser is too low. Increase the water flow and/or check
the strainer for clogging.
RESET After finding the cause, push the
button on the high-pressure switch
housing and reset the controller.
Symptom 5.4: Reverse phase protector is activated
POSSIBLE CAUSES CORRECTIVE ACTION
Two phases of the power supply are
connected in the wrong phase
position.
Invert two phases of the power
supply (by licensed electrician).
One phase is not connected
properly.
Check the connection of all phases.
RESET After inverting two phases or fixing
the power supply cables properly,
the protector is reset automatically,
but the controller still needs to be
reset.
Symptom 5.5: Discharge thermal protector is activated
POSSIBLE CAUSES CORRECTIVE ACTION
Unit is working outside the operation
range.
Check the operation condition of the
unit.
RESET After temperature decrease, the
thermal protector resets
automatically but the controller still
needs to be reset.
Symptom 5.6: Flowswitch is activated
POSSIBLE CAUSES CORRECTIVE ACTION
No water flow. Check the water pump.
RESET After finding the cause, the
flowswitch is reset automatically, but
the controller still needs to be reset.
Symptom 5.7: Freeze-up protection is activated
POSSIBLE CAUSES CORRECTIVE ACTION
Water flow too low. Increase the water flow.
Inlet temperature to the evaporator is
too low.
Increase the inlet water temperature.
flowswitch is not working or no water
flow.
Check the flowswitch and the water
pump.
RESET After temperature increase the
freeze-up is reset automatically, but
the circuit controller needs to be
reset.

- Description 4
- Escription 4
- As the refrigerant circulates through the unit changes in its state or condition occur these changes are caused by the following main components 5
- Compressor the compressor m c acts as a pump and circulates the refrigerant in the refrigeration circuit it compresses the refri gerant vapour coming from the evaporator at the pressure at which it can easily be liquefied in the condenser 5
- Condenser the function of the condenser is to change the state of the refrigerant from gaseous to liquid the heat gained by the gas in the evaporator is discharged through the condenser to the ambient air and the vapour condenses to liquid 5
- Evaporator the main function of the evaporator is to take heat from the water that flows through it this is done by turning the liquid refrigerant coming from the condenser into gaseous refrigerant 5
- Expansion valve the liquid refrigerant coming from the condenser enters the evaporator via an expansion valve the expansion valve brings the liquid refrigerant to a pressure at which it can easily be evaporated in the evaporator 5
- Figure 5
- Filter drier the filter installed behind the condenser removes small particles from the refrigerant to prevent blockage of the tubes the drier takes water out of the system 5
- Flowswitch the flowswitch protects the evaporator of the unit against freezing when there is no waterflow or when the waterflow is too low 5
- Function of the main components 5
- Functional diagram 5
