7.1 Electrical fuse (if available)
To find out whether your temperature control unit is equipped with fuses, refer to the “Wiring
diagram”. → From page 46, section »Annex« .
The overcurrent circuit breakers for all pole breaking (L and N) are located at the back of the tem-
perature control unit. In case of a fault (no function and no display on the temperature control unit)
please first check if the overcurrent circuit breaker has tripped. If the overcurrent circuit breakers
immediately trip again after the reset: Unplug the power cord and immediately contact Customer
Support. → Page 45, section »Contact data« .
