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 the control’s requirements. Separate the probe cables
from the power supply cables, 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’s.
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 at the warmest loacation of return 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.
