Miscellaneous
Delay of output signals after start-up
Input signal on DI1. Function:
0=not used. 1=status on DI1. 2=door function with alarm when open. 3=door alarm
when open. 4=defrost start (pulse-pressure). 5=ext.main switch. 6=night operation
7=change reference (r40 will be activated) 8=alarm function when closed. 9=alarm func-
tion when open. 10=case cleaning (pulse pressure). 11=Inject off when open.
Network address
On/Off switch (Service Pin message)
Access code 1 (all settings)
Used sensor type (Pt /PTC/NTC)
Display step = 0.5 (normal 0.1 at Pt sensor)
Max hold time after coordinated defrost
Configuration of light function (relay 4)
1=ON during day operation. 2=ON / OFF via data communication. 3=ON follows the DI-
function, when DI is selected to door function or to door alarm
Activation of light relay (only if o38=2)
Case cleaning. 0=no case cleaning. 1=Fans only. 2=All output Off.
Access code 2 (partly access)
Replace the controllers factory settings with the present settings
Re alternative application for the S5 sensor (maintain the setting at 0 if it is used as
defrost sensor, otherwise 1 = product sensor and 2 = condenser sensor with alarm)
Select application for relay 4: 1=defrost, 2= alarm
Service
Temperature measured with S5 sensor
Status on DI1 input. on/1=closed
Status on night operation (on or off ) 1=closed
Read the present regulation reference
Status on relay for cooling (Can be controlled manually, but only when r12=-1)
Status on relay for fans (Can be controlled manually, but only when r12=-1)
Status on relay for defrost. (Can be controlled manually, but only when r12=-1)
Temperature measured with Sair sensor
Status on relay 4 (alarm, defrost, light). (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 recon nect the supply voltage
