Tab.4.h
Note: when using Carel 0-10V probes, connect the probe power supply +(G) to terminal “G” on the
board rather than terminal 3U.

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 1U, 2U), digital remote on/off
input (terminals 7U, 8U) and shielded cable for RS485 communication.

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 configuration,
typical of air handling units, the controller continues managing steam production according to the
humidity requirement, however production is limited according to the relative humidity measured in
the outlet duct.
