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

Warning ! Direct start of compressors **
To prevent compressor breakdown parameter
c01 and c02 should be set according to
suppliers requirements or in general :
Hermetic Compressors c02 min. 5 minutes
Semihermetic Compressors c02 min. 8
minutes and c01 min. 2 to 5 minutes ( Motor
from 5 to 15 KW ).
** ) Direct activating of solenoid valves does
not require settings different from factory (0)
