Error code:

EC

Reason:

The evaporator probe T2 measures the actual value with the compressor start and takes

this as the reference value T

Start

. If, 5 minutes after the compressor start, the value T

Start

has not dropped by 2 °C for at least 4 seconds then the system assumes that the refrig-

erant is low. The measurement is performed a total of 3 times before the display shows the

error code "EC".

Cause:

n

Refrigerant low or cooling circuit blocked

n

Evaporator probe T2 defective

n

Indoor unit control board defective

Switch off voltage, switch on again 2 minutes

later. Is the error still present?

 

YES

Check whether the indoor unit blows out cold

air.

YES

Check the position and function of the evapo-

rator probe T2. Is it correctly seated and with

the correct resistance?

NO

 

YES

Check the cooling circuit for leaks. Leaks

found?

 

Exchange the control boards of the indoor unit.

 

YES

Remedy leaks and put the unit back into opera-

tion.

NO

 

Check the cooling circuit for any blockages. Are

the shut-off valves on the outdoor unit open?
