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
Six start times for defrost.

Miscellaneous
Delay of output signals after start-up o01 0 s 600 s 5 s
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. o02 0 11 0
