Please Note: The Honeywell Home TH6320ZW2003/U T6 Pro Z-Wave Plus smart thermostat has been discontinued and replaced by the TH6230ZW2007/U model number.

Honeywell TH6320ZW2003/U Product Description:


The Honeywell Home TH6320ZW2003/U T6 Pro Z-Wave Plus Smart Thermostat is capable of controlling up to three heat and two cool stages of heat pump, (including dual fuel heat pump systems) and up to two heat and two cool stages of conventional system (3H/2C HP, 2H/2C Conv.) It also measures, displays and reports % indoor relative humidity; however, this model does not control humidification equipment.

The Honeywell TH6320ZW2003 is programmable thermostat that is most commonly used with Honeywell Lyric Controller and ProSeries alarm control panels. With this programming thermostat you can control your temperature from anywhere using your Android, BlackBerry or iPhone device. It is one of the easiest smart thermostats to install and is controllable by all Z-Wave compliant controllers that have the control capability for "Thermostat" devices. When integrated with the app that controls your Z-Wave controller, it lets you program and control your home's HVAC system as well as controlling other Z-Wave devices connected to the same Z-Wave controller.

Because the thermostat is battery-powered, low-voltage integrators can easily connect the thermostat to most HVAC systems. Optional 24 VAC powering via "C" or common wire is also available, if desired.

Product Includes:

  • T6 PRO Z-Wave Thermostat
  • UWP™ Mounting System
  • Honeywell Standard Installation Adapter (J-box adapter)
  • Honeywell Decorative Cover Plate - Small; Size 4-49/64 in = 121mm.

Please Note: For installation of the Honeywell T6 Pro smart thermostat, you should have knowledge of your high-voltage HVAC system. If not, we recommend you hire an HVAC technician to install on your behalf due to the risk of injury to a non-professional. GeoArm will not troubleshoot wiring and power issues without an HVAC Technician present.
