ELECTRICAL CONNECTIONS

The controller is provided with a screw terminal block to connect cables with a cross section up to 2,5 mm

2

. Before

connecting cables make sure the power supply complies with th

e control’s requirements. Separate the probe cables

from the power supply cables, and the outputs and the power connections. Do not exceed the maximum current
allowed on each relay. In case of heavier loads use a suitable external relay or contactor.


PROBE CONNECTIONS

The probes shall be mounted with the bulb upwards to prevent damage due to casual liquid infiltration. It is
recommended to place the thermostat probe away from air streams to correctly measure the average room
temperature. Place the defrost termination probe among the evaporator fins in the coldest place, where most ice is
formed, far from heaters or from the warmest place during defrost to prevent premature defrost termination.
