Additional Information

Z-Wave Compatibility

You can use Z-Wave technology to optimize your energy usage by controlling this thermostat, as well as many other devices you may have installed throughout your home.   There are many choices: You could create automated heating and cooling routines based on time and day, or whether or not someone is at home.  Z-Wave can be used to automatically lower your motorized window shades when the windows are in direct sun, and then inform the thermostat to adjust itself to a more economical setting. 


The TH8320ZW is compatible with a broad range of 24-volt heating and air conditioning systems: single-stage and multi-stage heating and cooling systems, heat pumps with and without auxiliary heat, gas fireplaces, hot water, and heating only or cooling only systems. It is not compatible with electric baseboard heat.


Many older homes are wired with 4-conductor cable.  Unlike the original tnermostat supplied with a four-wire system, the TH8320ZW thermostat is capable of controlling the AC compressor and the circulating fan separately.  To do this a "common" wire is used. The included Wiresaver module can be used to simulate an additional wire.  The Wiresaver 'splits' an existing wire and uses it to carry both compressor and fan commands. It's simple to install (instructions are included) and mounts next to your HVAC system.
