Ok guys, I've been out of the field since before these things came out and moved into commercial service management. Looking for some help from those of you that work with this stuff everyday.
Friend has 90+ propane furnace with 2 speed a/c. He gets free wood and has installed an outdoor wood boiler with hot water coil above the furnace. We want to integrate the boiler demand into the system so that it is 1st stage heat and then use a toggle switch to enable the furnace run as it normally would if he goes away during the winter or runs out of wood.
I believe the infinity zoning panel is a SYSTXCC4ZC01. The furnace is 2 stage var spd with 24v terminals and has a small communicating control adapter plugged into the board. So the ABCD bus runs from the damper control to the furnace and then out to the condensing unit. The system does have the smart sensors on each of the four zones.
I first thought to put a 3way switch on one leg to the inducer motor and have it switch to a relay to fire the boiler, but this would obviously cause furnace fault codes, so I am looking for another way to do this. I wonder if there is an aux heat interlock accessory?
I know this post is a little light on details like model numbers etc...but if anyone has any input on whether something like this is possible or not, it would be much appreciated.
I realize this is fairly unconventional but someone that works with this equipment regularly may have figured out a way to do stuff like this.
Thanks in advance!
