From what I can tell it is a trolatemp auto opposed blade demper with mastertrol minizone 2? Now that you pointed me out to this I found schematics http://customer.honeywell.com/techli...0s/69-1361.pdf
, that I will try to understand. As far as I can tell everything is matching schematics.
At the system brown and blue wires are not connected.
I think I wired the MB incorrectly only I am not sure how it is supposed to be.
Thanks in advance for any advice and help
I am almost there..
I connected yellow wire to Y, white to W, green to G, blue to B, and brown to O with red going to RH jumped to RC. Guest room now turns on and off both air conditioner and fan independently of master. However master demper does not turn off air flow when AC is on and temperature is set to above current. Almost there..i think...but still need some help..
