ECO 6 – User and installation manual
Release 5.1 9
Install the NTC thermostat probe in a position not subjected to airflows in order to be able to
measure the actual temperature of the refrigerated compartment. The NTC probe is enabled by
IS1 parameter; to connect the NTC probe to the board use a 6-pin male connector, 3.81 step. OF1
parameter is dedicated to the calibration of the S1 thermostat probe.
Position the defrost-end evaporator probe between the lamellar pack fins in order to obtain a
sufficient temperature detection sensitivity. For refrigerating units with electric defrosting, the
probe must be positioned at the beginning of the circuit and locked in contact with the evaporator
pack tube by bending the aluminum slats around the probe bulb. For the groups with hot gas
defrost the probe must be positioned at the outlet of the circuit and locked in contact with the
evaporator pack pipe. To connect the NTC probe to the board use a 6-pin male connector, 3.81
step. OF2 parameter is dedicated to the calibration of the S2 evaporator probe.
Fix the condenser probe with a clamp on the condenser outlet tube. To connect the NTC probe to
the board use a 6-pin male connector, 3.81 step. OF3 parameter is dedicated to the calibration of
the S3 condenser probe.
The digital input D1 is dedicated to the micro-switch door, observing the configurable contact n.o.
or n.c.. To connect the micro-switch cables to the board, use a 2-pin or 4-pin male connector, 3.81
step.
The digital input D2 is dedicated to the high pressure switch, observing the configurable contact
n.o. or n.c... To connect the pressure switch cables to the board, use a 2-pin or 4-pin male
connector, 3.81 step.
