| It is now working! I ended up calling the manufacturer who directed me to someone in their engineering department. According to the engineer, the humidistat has a built in safety switch that will not allow the humidifier to engage whenever the outdoor temperature is above 50 degrees. This safety switch works whether the humidistat is in manual mode or auto mode whenever the outdoor sensor is wired into the humidistat. Disconnecting the sensor disables the safety switch, which allows the humidifier to operate in manual mode.
The instructions/website/box do not mention this small bit of information anywhere, even though it might be useful to someone installing a humidifier in warmer Fall weather in anticipation of cold weather ahead. I falsely assumed that "manual" mode meant if I "manually" cranked the humidity up to 60% to test my installation it would engage.
So it turns out I had it wired correctly from the start. Many thanks to Jay for assuring me I had it wired correctly which lead me down a different path. I didn't want to call the manufacturer without knowing that the problem wasn't something I had done with the wiring configuration.  |
