humidistat keeps water flowing??
Hi everybody, here is my question:
I have a humidifier on my furnace. There is a 24V wire that goes to the humidistat and from there to the transformer. But nothing that connects this system to the furnace.
So the problem is, when the humidistat opens up the water supply to the humidifier, it keeps flowing and the water ends up down the drain, not adding at all to the humidity in the house and it keeps going whether the furnace is running or not. What is wrong with this setup?
PS I looked at the circuit board in the furnace, and there is no connection for any wire for a humidistat.
I have an Aprilaire 550 humidifier and an old, 80% furnace, make unknown.
Install a sail switch or a current sensor relay so it only runs when the fan runs.
