Important: connect the yellow-green cable to the earth point
(GND).
4.3 Temperature probe connection (M2.1-
M2.8)
the humidi er can be connected to up to two probes for measuring
and controlling the temperature inside the steam bath. The connection
with two probes allows an “average” temperature reading (with the
possibility to attribute a di erent “weight” to each probe, see par. “7.3
Temperature probes”, page 21);
active probes (voltage or current signal, CAREL code: ASET030001) or
NTC probes (variable resistance) can be connected.
For connection, use the “eight pin” connection kit (supplied in the
packaging) and run the cables out of the humidi er through the “cable
opening” (Figs. 4.a or 4.b).
