I have an Aprialaire 56 humidistat that is connected to an Aprialaire 560 humidifier. Currently the humidifier is not turning on and after testing the wiring with a multimeter, the wires going in to the humidistat are not getting a current.
This system was installed by the previous homeowner and was tested and working previously to my knowledge.
The humidistat is wired into the furnace control panel in the
W2 terminals. From my research,
W2 is "stage 2" of the furnace heating cycle. My thought is to move the wire from
W1 in order to draw power to the humidistat.
Are there any other remedies to troubleshoot why the humidistat and in return the humidifier are not powering on?
