Input signal on DI1. Function:

(0=not used. , 1= door alarm when open. 2=defrost start

(pulse-pressure). 3=ext.main switch. 4=night operation

Access code 1 (all settings)

Used sensor type (Pt /PTC/NTC)

Display step = 0.5 (normal 0.1 at Pt sensor)

Access code 2 (partly access)

Save the controllers present settings to the programming

key. Select your own number.

Load a set of settings from the programming key (previ-

ously saved via o65 function)

Replace the controllers factory settings with the present

settings

Select application for S5 sensor (0=defrost sensor, 1=

product sensor)

Select application for relay 2: 1=defrost, 2= alarm relay

Service

Factory setting

If you need to return to the factory-set values, it can be done in this way:

- Cut out the supply voltage to the controller

- Keep upper and lower button depressed at the same time as you recon nect the supply voltage

Warning ! Direct start of compressors **

To prevent compressor breakdown parameter

c01 and c02 should be set according to

suppliers requirements or in general :

Hermetic Compressors c02 min. 5 minutes

Semihermetic Compressors c02 min. 8

minutes and c01 min. 2 to 5 minutes ( Motor

from 5 to 15 KW ).

** ) Direct activating of solenoid valves does

not require settings different from factory (0)
