Start-up delay time
Set the delay before the unit starts up.
After the freezer is powered up, the first stage
compressor will start only after this delay has passed.
Note:
This parameter can also be set on the Essential model. This operation must be performed by a qualified technician. It
entails opening the rack and setting switches on the Artic board.
The switches marked “SW1” should be set to allow at least 5 seconds between each start-up. The number set in
binary corresponds to a delay of 30 seconds + the number of seconds encoded in binary.
