My whole house humidifier isn't working and I found that I'm not getting 24v power to the humidistat. I traced that back to the thermostat terminal on the furnace that's supposed to output 24v power and I found the white wire going to the humidistat is disconnected. The red wire is connected to the "C" terminal.
Here's the wiring diagram to my furnace. Any idea where the white wire should connect to?  |

Normally it would be connected to the W when wired like this the humidifier would only work when the heat is running.
A better way would be to add a relay so when the humidstat calls it turns the fan and the humidifier on instead of just when the heat is running |
