Outdoor unit error display (control board

flashing code of the outdoor module)

In the event that the red control lamp lights up on

the indoor module, then the fault is on the outdoor

module. Two LEDs are visible after removing the

enclosure panel which light up in green and red

during normal operation (see adjacent figure). If

the LEDs flash, then there is a fault. Causes and

measures for their remedy can be taken from the

following table. (

= flashing)

Fig. 64: 1: Green and red LEDs

Green

Red LED

Meaning

Remedial measures

Phase error: The supply cable to the

outdoor module or the connection

between the indoor and outdoor mod-

ules is not correct.

Check the electrical connection

(swapped phases), check connection

cable

One of the connectors has been

removed from the PCB or has intermit-

tent contact

Check all connectors on the PCB,

check high and low pressure sensors

ZZZ

Fault on PCB

Exchange PCB

Wiring error between indoor and out-

door modules

Check connection cable for correct

polarity and proper contact

Data transfer error between indoor and

outdoor modules

Check if the connection cable has

been improperly extended or incor-

rectly connected

ZZZ

Hot gas temperature in refrigerant cir-

cuit too high or hot gas heating too low

Check refrigerant; check hot gas tem-

perature sensor; check expansion

valve

High pressure valve has tripped

Open any closed ball valves, check for

excess refrigerant

Low pressure cut-off switch has tripped Open any closed ball valves, check for

excess refrigerant

No voltage on condenser

Check power supply to the condenser

ZZZ

Overheating protection tripped, exces-

sive liquid temperature in refrigerant cir-

cuit

Clean dirty heat exchanger on outdoor

module, rectify possible pneumatic

short circuit on the outdoor device

ZZZZ

Circuit breaker on condenser (overload)

has tripped, or no operating voltage at

the condenser

Open any closed spherical valves,

check supply voltage, exchange faulty

control panel

ZZZZZ

Fault in hot gas temperature sensor or

fin temperature sensor (cable breakage

or short circuit)

Check PCB connector for firm connec-

tion, check functionality of the sensor

ZZZZZZ

Temperature fault on inverter cooling

block

Rectify obstruction to flow in outdoor

module

ZZZZZZZ

Fault in power supply

Check and repair power supply

ZZZZ

Fault on liquid line sensor (cable

breakage or short circuit)

Check PCB connector for firm connec-

tion, check functionality of the sensor

ZZZZ

Temperature of liquid line too high / too

low

Check refrigerant line. Lack of refrig-

erant
