Hello!
I have a whole house humidifier, and the humidistat has seen better days. The plastic strip thingie that determines the humidity has failed, so the unit sits in the extra dry house air.
The humidifier is an old Sears unit, that works well. The humidistat mounts into the air return, I have the contact closed, so the humidifier works whenever the furnace runs now, better to have the humidity than a dry mouth.
Here's my issue: The current humidistat uses line voltage, and when needed, the switch closes and the humidifier turns on. A replacement line voltage humidistat is quite expensive, so I'm figuring to go with a 24V humidistat. That's where I get a little foggy in how to do it.
I know I would take the Line In to a transformer, down to 24V for the humidistat. The humidistat would do it's job, and I assume run a signal to a relay that would turn on the humidifier.
Now, what do I need for a relay? The box store has a transformer, so that's not an issue.
Can I use the line feed to the transformer over to the In on the relay? That would allow the Out to power the humidifier.
I guess it depends on the relay, but how would I go about mounting this set up? A new question is, it there an all-in-one unit that would keep me from re-inventing the wheel?
Thanks in advance,
Ray
