I am installing an Aprilair model 400 humidifier into my old Carrier air handler, running off the Carrier heat pump. I have a Honeywell TH8320 thermostat.
Here is my problem. The Aprilair destructions call out for a hook-up to W. Well, on my thermostat there is no W.
Here is the humidifier wiring diagram: http://www.aprilairepartners.com/pro...iers/83218.pdf
For the thermostat, I am using the 2H/1C connection wiring guide, shown on page 5. http://www.hydro-temp.com/help/drawi...069-1894ES.pdf
You can see the air handler board connections here: http://www.docs.hvacpartners.com/idc...im-fa4a-11.pdf
How should I hook this up? Should I hook it to Y, the compressor?
Sorry about all the links.
