Max. defrost duration
Displacement of time on cutin of defrost at start-up
Defrost sensor 0=time, (B:1=Sair.) (C: 1=S5, 2=Sair)
Defrost at start-up
Max. aggregate refrigeration time between two defrosts
Defrost on demand - S5 temperature's permitted variation
during frost build-up. On central plant choose 20 K (=off )
Miscellaneous
Delay of output signals after start-up
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)
(Can only be set when regulation is stopped (r12=0)
Replace the controllers factory settings with the present
settings
Select application for Saux sensor (0=not used, 1=product
sensor, 2=condenser sensor)
Select application for S5 sensor (0=defrost sensor, 1=
product sensor)
Select application for relay 2: 1=compressor-2 / defrost, 2=
alarm relay
Service
Temperature measured with Saux sensor
Temperature measured with S5 sensor
Status on DI1 input. on/1=closed
Status on relay for cooling
Can be controlled manually, but only when r12=-1
Status on relay 2
Can be controlled manually, but only when r12=-1
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 reconnect the supply voltage
