· To use humidity-control, a humidity sensor must be connected to Optional Sensor1. Is this
humidity sensor a RH95/2 sensor, than connect as follows;
+12V to pin3 (dc+) of RH95/2 (V+ Supply humidity sensor),
Signal to pin2 (rh+) of RH95/2 (Signal 0-1Vdc = 0-100%RH) and
GND to pin1 (dc-) of RH95/2 (Common 0V)
Also set the Optional sensor1 input selection jumper J30 to volt, see connections
