CONTROL WITH ONE HUMIDITY PROBE
• short-circuit terminals 7U and 8U (jumper) to enable production; alternatively connect terminals 7U – 8U to a remote contact
(e.g.: switch, timer,...);
• connect the main active room probe to terminals 1U, 2U (GND) and 3U (+12Vdc);
• to enable control, set:
Notice: when using 0-10 V probes, connect the probe power (G) to terminal “14” on the terminal block “T” inside
the electrical panel, rather than terminal 3U.
