5.11.3.3 On/Off Humidistat Signal
If an On/Off humidistat is used, connect the signal cable to terminal pins "4" and "6" in the low voltage
terminal strip. Refer to Figure 29. Set Control Mode must be set to "On/Off" in the control software – refer
to the Operation and Maintenance Manual.
IMPORTANT! When connecting a 24 VDC On/Off humidistat, jumper JP2 on the driver board must
be set to 24 V (so that pin "6" will output 24 VDC).
Note: By default the jumper JP2 is set to 10 VDC, so that the output can also be used for test purposes.
