The control switch that came with bypass humidifier installed with my Trane heat pump started acting up – only turns humidifier water on when I turn the dial all the way to max. I'm thinking I need to replace it. It seems to have only 2 contacts, so my guess is I can just buy any other control switch, like this one and put it in instead:
Am I right, or there's more to it?
thanks

Replaced control switch, everything works great.
