Why is this on Y? Y is used for cooling.. The Vanee should be wired to Vnt.

From the humidifier the red wire goes to Hum2 and the white wire to C.
That is correct.. Is it turned on in the installer set up menu?

Venmar Solo to IAQ wiring

When I hooked up the replacement IAQ using the same terminals that were used on the PC8900 I don't get any humidity control, nor does it recognize the humidifier. Also, the existing outside temperature sensor now reads 127 degrees.

On the PC 8900 there was a jumper wired from the Hum 1 to the R terminal and from the RH to the R terminal. I wired the Hum1 to RH jumper but skipped the other one since it has a factory installed jumper.

Any ideas?
How is your venmar wired to the IAQ, R, B, G and Y terminals are on the venmar, wher do they attach on the IAQ EIM unit.

thanks, Rob

Rob,

G and B is what you wire to the EIM of the IAQ.
