Door open for too long

close door

High-pressure fault

Check: Condenser fan and check for dirt accumulation

Low-pressure fault

Plant leaking, to little coolant

EP0

Internal error in control unit

Repair control unit

EP1

Error in parameter memory

Check all parameters

EP2

Error in data memory

Repair control unit

rtc

Error of internal clock

Set clock again. If error occurs again, the controller must
be repaired

The

EP0

and

EP1

errors disable the controller. The controller is not enabled until the error has been eliminated.

The error

EP0

(and

EP2

) can only be removed by repair.

The errors are displayed alternately with the currently measured temperature.
