Description
Compressor return temperature probe
(Th)
Fan thermal
Compressor thermal
Inverter protection (IPDU and IR341)
Communication failure of secondary
management board
Return temperature probe of secondary
C1
Thermal pump of secondary C1
Possible cause
The Th sensor connector is loosening. Reconnect it.
The Th sensor connector is wet or there is water in. remove
the water, make the connector dry. Add waterproof
adhesive.
The Th sensor failure, change a new sensor.
Strong wind or typhoon below toward to the fan, to make
the fan running in the opposite direction. Change the unit
direction or make shelter to avoid typhoon below to the fan.
Fan motor is broken, change a new fan motor.
The same reason to F1/P1.
Power supply voltage of the unit is low, increase the power
voltage to the required range
Power supply voltage of the unit is low, increase the power
voltage to the required range.
The space between the units is too narrow for heat
exchange. Increase the space between the units.
Heat exchanger is dirty or something is block on the
surface. Clean the heat exchanger or remove the
obstruction.
Fan is not running. Fan motor or fan is broken, Change a
new fan or fan motor.
Insufficient coolant load. Recharge the refrigerant in right
volume.
Water flow rate is low, there is air in system, or pump head
is not enough. Release the air and reselect the pump.
Water outlet temp sensor is loosening or broken, reconnect
it or change a new one.
Water tank heat exchanger is smaller than the required
2 2
1.7m (10-16kW unit)or 1.4m (5-7kW unit)
Module wires or screws are loosening. Reconnect wires
and screws.
The Thermal Conductive Adhesive is dry or drop. Add
some thermal conductive adhesive.
The wire connection is loosening or drop. Reconnect the
wire.
Drive board is defective, replace a new one.
If already confirm the control system has no problem, then
compressor is defective, replace a new compressor.
ANOMALY ON CAN CONNECTION
disconnected wiring, DIP1 frame not correctly configured,
lack of power supply to the I/O card (check T1 outlet and
wiring), fuse 5F1
faulty or disconnected sensor
pump high absorption - air in the installation - defective
wirings - faulty pump
