Note: in industrial environments (IEC EN61000-6-2) the signal cables
leaving the unit must not exceed 30 m (98') in length: steam production
signal cable (terminals M2.1, M2.2), digital remote on/off input (terminals
M2.7, M2.8) and shielded cable for RS485 communication.

4.6 Control with humidity probes

The main control board, connected to a room humidity probe, manages
steam production based on the humidity measured. A second outlet
humidity limit probe can also be connected: with this confi guration,
typical of air handling units, the main control board continues managing
steam production according to the humidity requirement, however
production is limited according to the relative humidity measured in the
outlet duct.

CONTROL WITH ONE HUMIDITY PROBE
•
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);
