HAI controller for HVAC zones?

[5artist5]

I am looking into getting an HAI controller either the omniLT or the omniII and I wonder about setting up heating and cooling zones. I was planning on getting the OmnistatII to go with the setup. So if I get some of the HAI remote temp sensors and some duct dampers will either of these HAI controllers be able to take care of the whole thing?
Or am I looking at another controller for that?

I currently use HAI (Omni Pro II) with an OmniStat and multiple temperature / humidity sensors. My previous home had two zones which worked well.

I have not implemented utilizing HAI configured zones in my current home using dampers on returns but I do change the air flow manually on the returns from summer to winter and vice versa.

Configuring dampers with the HAI controller is straight forward. Check out some discussions relating to said endeavor on the forum.

The Omni basically controls the thermostats but not the dampers. Make sure the Omni you pick can control the number of thermostats you need. The OmniPro II can control a bunch of them. The dampers are controlled by zone controller. Basically the thermostats connect tot the zone controller and the zone controller connects to the HVAC through the thermostat connections. Lets say thermostat 1 wants heat. It tells the HVAC to make heat, then it controls the damper for zone 1 to get the heat to that zone. When no thermostat wants heat, it turns the HVAC off. I don't think HAI makes zone controllers, but that isn't a problem because any should work. Again, the zone controller doesn't connect to the panel and its not controlled by the panel, its controlled by the thermostats. You could use HAI relays and remote temp sensors to control the dampers, but unless you only have one or two, I wouldn't recommend it, unless you really want to go the inexpensive route. The best way is to put an Omnistat in each room and use a zone controller but that is more expensive of course.
