Tell us about yourself!
Final thought before I buy a board... apparently nest can Run the humidifier directly every time the heat turns on... the question remains wether the board will supply the 24v... could it be the humidistat is the problem? That will be my test tonight... thx for all your help...
Ok thx, any chance that my nest is demanding more out of the board? (Nest is not wired to control humidifier)..
Hi There, I'm am measure the voltage coming from the humidifiers thermostat to where the solenoid was.. I have the thermostat wide open with the furnace running, i get about 19-21 volts... occasionally I get 24 volts and i hear the solenoid click....the current issue is that the solenoid is not opening and no water is going through it, i've purchased two different solenoid thinking one was faulty until i realized the voltage seems to be the problem..? thanks
I'm not always getting 24v!? most times i get 19-21 volts going to the humidifier.. any ideas how i can regulate this?
