below “working setpoint+ r0”, at most “working setpoint + r0”; if to the defrost

(1) the unit of measure depends on parameter P2
(2) set the parameters related to the regulators appropriately after themodification of the parameter P2
(5) the modification of parameter d0 has effect since the end of the previous defrost interval or since the activation of a defrost by hand
(6) the display restores the normal operation as soon as the defrost ends and the cabinet temperature falls below the one that has locked the display (or if a
temperature alarm arises)

How to set the working setpoint
If you have to modify the working setpoint value:
• press
and or *
* you can set the working setpoint between the limits you have set with the parameters r1 and r2.
* unless the parameter r5 has value 0, you can not modify the working setpoint..
