Copy from the programming key

This function downloads a set of settings earlier saved in

the controller. Select the relevant number.

When copying has started the display returns to o66.

After two seconds you can move back into the mennu

again and check whether the copying was satisfactory.

Showing of a negative ﬁgure spells problems. See the

signiﬁcance in the Fault Message section.

Fault message

In an error situation the LED’s on the front will ﬂash and the

alarm relay will be activated. If you push the top button in this

situation you can see the alarm report in the display. If there are

several, you can continue pushing to see them.

There are two kinds of error reports - it can either be an alarm

occurring during the daily operation, or there may be a defect in

the installation.

A-alarms will not become visible until the set time delay has

expired.

E-alarms, on the other hand, will become visible the moment the

error occurs.

(An A alarm will not be visible as long as there is an active E

alarm).

Here are the messages that may appear:

A1: High temperature alarm

A2: Low temperature alarm

A4: Door alarm

AA45: Standby position (stopped refrigeration via r12 or DI

input)

A61: Condenser temperature alarm

E1: Faults in the controller

E27: Sensor error on S5

E29: Sensor error on Sair

E30: Sensor error on Saux

When copying settings to or from a copying key with functions

o65 or o66, the following information may appear:

0: Copying concluded and OK

4: Copying key not correctly mounted

5: Copying was not correct. Repeat copying

6: Copying to EKC incorrect. Repeat copying

7: Copying to copying key incorrect. Repeat copying

8: Copying not possible. Order number or SW version do not

match

9: Communication error and timeout

10: Copying still going on

(The information can be found in o65 or o66 a couple of seconds

after copying has been started).

Operating status

The controller goes through some regulating situations where it

is just waiting for the next point of the regulation. To make these

“why is nothing happening” situations visible, you can see an

operating status on the display. Push brieﬂy (1s) the upper but

ton. If there is a status code, it will be shown on the display. The

individual status codes have the following meanings:

S0: Regulating

S2: When the compressor is operating it must run for at least x

minutes.

S3: When the compressor is stopped, it must remain stopped for at

least x minutes.

S10: Refrigeration stopped by main switch. Either with r12 or a

DI-input

S11: Refrigeration stopped by thermostat

S14: Defrost sequence. Defrost in progress

S17: Door is open. DI input is open

S20: Emergency cooling

S25: Manual control of outputs

S32: Delay on outputs during start-up

Other displays:

non: The defrost temperature cannot be displayed. There is no

sensor

-d-: Defrost in progress. /First cooling after defrost
