Real time clock error:
In case of a real time clock error the exact cause is indicated by the last figure of the display with a
hexadecimal code (“0”-“F”). This code is formed by the sum of the error values of the following
table:

Hardware error

In practice the error “Ur4” will occur most frequently. In this case the user has to reset the clock.
The error indication is active even in standby mode. However the error message can only be
cancelled if the controller is switched on.

Occurring errors are indicated with a flashing display and the buzzer sounds.

* If the display indicates a “EP” error the controller has located undesirable change of the
parameter settings in the EEprom. This indication can not be cancelled. The controller has to be
exchanged immediately! In this case the compressor and the ventilator switch to emergency
operation (15 min. on/15 min. off).

Common problems:

Setting of the ventilator setpoint with F7 is not possible

In case of an automatic day/night operation the night time reduction is activated as soon as the
light is switched off (depending on parameter H21). Therefore setpoint F8 becomes effective
instead of setpoint F7. If the light is switched on setpoint F7 is active again. If no night time
reduction is desired both F7 and F8 should be set to the same value.

As soon as the light is switched off the compressor is switched off too.

In case of automatic night time reduction the value of P6 will be added up to the setpoint. If the
light is switched off the new setpoint is active.
Remedy: set H6 back to “0”.

A change of the defrost interval d0 shows no effect.

The change is not effective until the next defrost period has started (or after mains on).
