Carrier Infinity Control

[joef]

I posted this in the residential section, but realized this is probably the right place.

My HVAC contractor is in the final phase of installing my new AC system (Carrier 38TXA 3 ton). They have hit a small stumbling block trying to interface the Infinity controller with my system. They are doing some research, but I thought I'd ask here.

My heating system is hot water baseboard with a Burnham boiler controlled thru a Taco zone control (3 zones). The Infinity control will be installed in the main hallway. The current thermostat in the hall controls one heat zone and all cooling.

Any ideas how this thing should be wired up? Thanks.

Yes. But it's kinda complicated, so I won't be able to tell ya over the Net. What I CAN tell you is this: It has something to do with four t-stat wires, two special circuit brds, a VS motor & a special t-stat.

That sounds a bit complicated. I'd prefer to have only one t-stat controlling both heat and cool, but its starting to sound like going with 2 may be the right choice. Probably not good to have a system that the only guy that can fix it, is the guy that installed it. My only beef is that I specifically asked the estimator/salesman if the Infinity would control both. He said "no problem". I guess that's what happens with new high tech equipment.

no. it won't work with the 3 zone boiler system. use the separate controls as considered in your residential post.
