Overview

  • Set different temperatures in different areas for comfort and energy savings
  • Thermal equalizer prevents overheating of top floor of 2-story homes
  • Works with standard thermostats, any heating system, and with X10 or RS232/485 thermostats for automation control

Essential Info

In most homes, heating and cooling account for a large part of the energy bill. Despite this, most homes waste a tremendous amount of heat and cool air through inefficient use. Efficiency can be significantly improved by heating or cooling only when occupants are present and by heating/cooling to the exact desired temperature. Home automation and zoned HVAC (heating, ventilation, air-conditioning) can do this for you automatically. You can set different desired temperatures in each room, and by using motion detectors, you can automatically turn ON/OFF the heating/cooling to each zone as people enter and leave. The energy savings in the average home over just a few years will often pay for the entire home automation system. The 24V AC 40VA Power Supply w/Auto-Resetting Fuse is required and sold separately.

    How it Works
    Convert a standard heating and cooling system into a system that provides independent temperature control of two zones within a home. Simply install a thermostat in each zone and then wire them to the HVAC 2-Zone Controller. Install dampers in the ducts feeding the different zones and wire those back to the zone controller. Finally, connect the zone controller to your heating/cooling system. The zone controller will automatically coordinate damper and HVAC system control to maintain the temperatures set in each zone. The HVAC 2-Zone Controller includes a thermal equalizer feature that's ideal for two-story homes. It uses timed recirculating cycles during lower floor heat calls to prevent excessive heat build-up in upper floors. This also helps save energy by recycling heat back to the lower floor.

    How This System Saves You Money
    A simple common-sense analysis of unzoned systems will show you how much you can save. Imagine a two-zone home with the living room as one zone and the bedroom the other zone. An unzoned system always heats/cools both rooms simultaneously even if only one zone is occupied. This means that twice as much energy is being used as necessary. Add to that any periods when the system is accidentally left on when no one is home, and you can see how wasteful this system can be. An automated zoned system will only heat/cool the room that is being occupied. The occupied room will also be heated or cooled to the desired temperature much faster. This is because the energy that would otherwise be wasted on the unoccupied room is being directed to the occupied room.

    HVAC and Home Automation System Compatibility
    This controller will work with most standard electronic thermostats and gas/electric heating systems and A/C systems. Uses 24VAC normally open dampers, automatic heat/cool changeover, built-in short cycle protection for A/C compressor. Combine with any X10 or RS232/485 thermostats for additional zone control through your intelligent controller.

    4-Zone System Available
    A 4-Zone HVAC Controller is also available for larger homes or those that need more specified control.

    Very simple to install works as per description. Actually easier to install and understand dipswitch settings. Works great with my Trane forced air gas furnace and Trane Central Air. Upstairs and Downstairs balanced within a degree and indoor humidity levels are great and balanced. Furnace will power the controller and controller will power two dampers without a power supply.
    EVERETT -- newport news, VA   2/14/2010
    Locating the 24V power source from the HVAC was a bit of a mystery for me, a DIY type. But I figured it out and the controller works as advertised. Wired in two-programmable thermostats (upstairs & downstairs) with very good comfort throughout the cold days. Looking forward to warmer weather to see how the AC "side" works out.
    MICHAEL -- lilburn, GA   2/14/2009
    Works like a dream. Easy install. Great value considering you save 3-$4k on installing another hvac system
    JAMES -- pittsfield, MA   1/6/2008
    Very good diagrams and discriptions of how to install, very simple
    Jerry -- Wilton NH   10/6/2011
    Nowhere on the description is the fact that this will only control a single stage of heat/cool. This severely limits the application of this and this information is buried in the users manual rather than prominent in the Essential Info section. Had I know this I would not have bought this device as I require a 2 stage controller. Other than this limitation, it looks like it would install easily and should work fine.
    JASON -- framingham, MA   8/6/2007
    Value for money, like I have not seen in a long time. Took me about 30 mins to install (wiring to upstairs took longer of course). Followed the instructions, and now upstairs calls when it needs it and downstairs too. In teh heat of summer, instead of cooling the whole house while we sleep, we just cool upstairs. The A/C runs about 40% less than it used to. This will pay for itself in a couple of months.
    RUSSELL -- newport coast, CA   1/20/2007
    works great, just like it is supposed to. Controls 2 zones using 2 thermostats and one system. Simple to install.
    DONALD -- atlanta, GA   8/16/2006
    just what the doctor ordered - easy to understand directions, works like a charm
    NORMAN -- roswell, GA   2/23/2006
