Aprilaire 700 wiring to Honeywell Prestige IAQ with EIM
I have a Honeywell Prestige IAQ 2.0 thermostat (9321) and the associated Equipment Interface Module, outdoor sensor, etc. I just got a new humidifier and am trying to wire it so the thermostat will control it's operation. What do I need to do?
