Here is the basic situation - we have a home which needs to be zoned in order to address hot & cold spots along with providing adaquate air flow in all areas. Saving fuel by only heating certain areas at certain times is not important to us. Thus, the zones will be:
- Main House
Objective is to address the following problems:
- Avoid stale air in basement (but keep temperature at same level as rest of house) by recirculating air when furnace / AC is in off cycle.
- Accomodate nearly a one ton afternoon solar gain in the Solarium when sun is out (total load for entire house is only 2.1 ton).
- Humidity is more of a problem than heat for us so want a zone controller which supports using the AC for dehumidification.
Furnace and AC will be replaced at same time. We are currently leaning towards going with a Rheem RGRM 2-stage Furnace w ECM Variable Speed & RARL 2-stage AC but are open to others.
Carrier's Comfort Zone II looks interesting as does Honeywell's Envirazone.
Any thoughts would be greatly appreciated!
