CONTROL WITH TWO ACTIVE TEMPERATURE PROBES
•
short-circuit terminals M2.7 – M2.8 (jumper) to enable production;
alternatively connect terminals M2.7 – M2.8 to a remote contact (e.g.:
switch, timer,...);
•
connect the main active room probe to terminals M2.1, M2.2 (GND)
and M2.3 (+12Vdc);
•
connect the second active probe to terminals M2.5, M2.3 (+12Vdc) and
M2.6 (GND);
•
to enable control, set:
Screen ind. Screen desc.
Ea01 Control type
Ea02 Control with 2 probes Set the weight of the two probes (0-100%)
Ea05 Modulating control
Ec01 Main probe type
Ec02 Second probe type
The controller will calculate the weighted average between the two
probes. The weight of the two probes can also be set.

4.8 Alarm contact

The humidifi er controller is fi tted with a relay contact for remote signalling
of one or more faults or alarms. The alarm contact (250 Vac; max capacity: 2
A resistive - 2 A inductive) is connected to terminals M6.1, M6.2 and M6.3.
