Defrost stop temperature
Interval between defrost starts
Max. defrost duration
Displacement of time on cutin of defrost at start-up
Drip off time
Delay for fan start after defrost
Fan start temperature

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)
