FAULTS
6 720 803 687 (2012/11) 63
EC Time limit exceeded for start of
operation
The system has not initialised
correctly after 4 minutes have
elapsed since start of operation. The
fault display “EC” is shown.
Poor connection/contacts or terminal loose at the
control cable connections or wiring error.
▶ Check and repair contacts, cables and control cable
connections for all appliances.
Control cables incorrectly sized. ▶ Check and correct control cable cross-section and cable
lengths: max. length 30 m (internal unit - external unit) or
max. 30 m (internal unit - internal unit).
▶ Check and correct polarity of control cables S1, S2 and S3.
Noise in the control cables. ▶ Check the control cables and eliminate cause of noise.
U1 High pressure too high (63H
tripped)
The high pressure switch 63H
tripped because the high pressure
rose above 4.14 MPa during
compressor operation.
Faulty ball valve (not completely open). ▶ Check if all ball valves are completely open.
Clogged or broken refrigerant line. ▶ Check pipe work and eliminate fault.
Blocked fan motor on external unit. ▶ Check external unit and replace or repair faulty
components.
Faulty functioning of external unit fan motor.
Air short circuit on external unit.
Contamination on the external unit's heat
exchanger.
Reduced air flow rate due to faulty temperature
measurement on outside temperature sensor
(measurement too low).
▶ Check outside temperature sensor including connections
and cable, and replace if required.
Faulty contact on plug 63H on the PCB of the
external unit.
▶ Switch the supply voltage off and on again.
▶ Check whether fault code “F5” is then displayed.
If yes, see “Possible solution / check” for “F5”.
Faulty connection of 63H.
Faulty external unit PCB
Faulty linear expansion valve (LEV). ▶ Check linear expansion valve (LEV).
Faulty fan operation. ▶ Replace faulty external unit PCB.
