Aprilaire humidifier Controls
I have a Honeywell T10 thermostat, it can control a humidifier. It uses 2 wire U terminal. I would like to install the Aprilaire 865 unit as my house has no ductwork. I notice install instructions thermostat uses 4 wires. What would be required to get this working off of the Honeywell Thermostat, I'm assuming some sort of simple relay. I attached the instruction wiring page.
