Carrier MPV Furnace & Aprilaire humidifier
The unit is an Aprilaire 600. No fan in the unit. I was told to wire it directly to the furnace and not to use the Aprilaire humidistat to allow humidity to be adjusted via the infinity thermostat. Currently, the senenoid is wired to the HUM and the Com 24 V. Unfortunatly, no humidity is being added to the air.
My furnace has the following terminals:
W2, Y1, DHUM, G, Com 24V, W/W1, Y/Y2, R.
Also, the salesman sold me a current sensing relay to add to the line. The relay has one solid black wire and one red and black striped wire. Any suggestions?
Thanks for your help.
