Fan Coil Unit Wall Mounted Type
Phenomenon Troubleshooting
Cracking noise:
• This is the sound of friction caused by expansion and/
or contraction of panel or other parts due to the change
of temperature.
The unit can not be started up:
Breaking off
• Is the power cut off?
• Is the power plug loose? (If applicable )
• Is the circuit protection device tripped off?
• Is voltage higher or lower?(Tested by professionals)
• Is the TIMER correctly used?
Cooling/Heating effect is poor:
• Is temperature setting appropriate?
• Is the inlet or outlet blocked?
• Is the lter dirty?
• Is the window or the door open?
• Is low fan speed set?
• Are there heat sources in the room?
Remote controller is not available:
• Check if there is magnetic or electrical interference
near the unit that may affecting operation of the
controller. In this case, pull the plug out and reinsert it.
• Is the remote controller within its operating range or
obstructed? Check the condition of the batteries and
replace them if necessary.
• Check if the remote controller is damaged.
Water leakage of FCU.
• The humidity is high.
• Condensate overows.
• Drain hose is loose.
Noise from FCU. The noise emitted when the fan is switching on or off.
FCU can not blow air:
• In HEAT mode, when the temperature of FCU heat
exchanger is very low, air flow is stopped in order to
prevent cold air.
• In COOL mode, when the temperature of FCU heat
exchanger is very high, air flow is stopped in order to
prevent hot air.
Moisture on air outlet :
If the unit operates at high humidity for a long time,
moisture will be generated onthe air outlet grill and then
drip off.
C5:Malfunction of connector jumper:
Check if the connector jumper contacts properly. If the
PCB is to be replaced, please take off the old for the
new PCB.
