devices function correctly.

• Calibrate the motor circuit breaker for the

compressor (if present) correctly as shown on the

following pages.

• After powering up the control, please check

the correct current absorption on the loads,

and after it has been running for a few hours

check that the screws on the terminal blocks

are suﬃciently tight (including power supply
