Improve Heating & A/C Comfort while reducing energy expenses!

These high quality HVAC zone controllers operate multiple, independent comfort zones in your home using your single heating and A/C system! Zoning reduces energy use by not heating or cooling unused zones. Improves comfort level within the home by allowing independent control of each zone\'s temperature. In addition, zoning improves your system\'s efficiency by satisfying heat/cool calls faster, and extends the HVAC system life reducing run times! For two story homes, the thermal equalizer feature does away with the age old problem of too much heat upstairs and too little downstairs, and provides for further energy savings by recycling the excess upstairs heat to the lower levels. These zone products work great in combination with RCS thermostats for communicating control by X10, RS485, UPB or  Zwave systems. Easily installed and comes in a compact 6\" x 8\" x 1.5\" one pound chassis.   

THERMAL EQUALIZER FEATURE

The ZTE version of the controllers includes the exclusive patented THERMAL EQUALIZER feature. This is used in two story, forced air applications to reduce the effects of heat stratification. Heat rises naturally and during heating cycles the upstairs zone tends to overheat. This loss of heat to the upstairs keeps the downstairs zone cooler and calling for more heat. This process continues until the upstairs is uncomfortably hot and the downstairs is still calling for more heat.

To balance this natural phenomena, the THERMAL EQUALIZER feature will monitor the length of time the heat has been calling downstairs and after a selectable time period, will stop the heat call and recycle the overheated upstairs air back down to the downstairs zone. This "equalizer cycle" will reduce the heat buildup upstairs and put the heat back downstairs where it is still needed. The net effect is a more comfortable temperature in the upstairs zone and an energy saving reuse of the excess heat in the downstairs zone.

The Thermal Equalizer feature monitors Zone 1 for heat run times and this zone must be the "downstairs zone". When the Thermal Equalizer cycle is on, the Zone 2 damper will be closed and the high speed fan turned on. Zone 2 must be the "upstairs zone" when using the Thermal Equalizer feature.

Note: Not compatible with Power Stealing Thermostats
