The Prestige® IAQ thermostat is a 2 wire high definition color touch screen thermostat, 7 day programmable and selectable for residential or light commercial use. Controls up to 4-stages of heat and 2-stages of cool in a heat pump system and up to 3-stages of heat and 2-stages of cool in a conventional system. Three sets of Universal IAQ contacts to control humidification, dehumidification, and ventilation. Four sensor inputs for wired sensors or dry contact devices. Works with the Equipment Interface Module and RedLINK® accessories including the RedLINK® Internet Gateway, Portable Comfort Control, Wireless Outdoor Sensor and Wireless Indoor Sensor.

  • Control humidification, dehumidifcation or ventilation
  • Adaptive Intelligent Recovery—over time, the Prestige thermostat “learns” how long it takes your system to reach the temperature you want. It turns on the heating or cooling system earlier to make sure you’re comfortable at the time you expect.
  • Dealer information on the screen—making it easy for you to contact your dealer for service.
  • Vacation and holiday scheduling—allowing you to program a setback temperature to save energy while you are away.
  • Keypad lockout to prevent unauthorized changes.
  • Equipment status—provides on/off status of all equipment controlled by the thermostat.
  • RedLINK™ wireless communication
  • Selectable for residential and light commercial applications. Meets commercial code and is title 24 compliant.
  • Tri-lingual - English, French and Spanish display options.
  • Performance Logs - Keeps a history of heating and cooling performance.

Included in the Honeywell YTHX9421R5085WG Box:
  • 1 Redesigned Prestige IAQ Thermostat

Stages of Heat

The number of terminals on the thermostat that can be used to individually control separate heating functions. Many furnaces that are called two stage heaters will require at least a two stage thermostat to operate appropriately. You may also choose a multiple stage thermostat when pairing different heating equipment. Such as a heat pump and a furnace.

Stages of Heat
4 w/ Heat Pump
Touchscreen

Interactive, touch-sensitive display screen.

Touchscreen
Yes
Stages of Cool

The number of terminals on the thermostat that can be used to individually control separate cooling functions. Some of the higher efficiency air conditioners and heat pumps are designed to use multiple stages of cooling.

Stages of Cool
2
Programming Days

The number days per week that the thermostat will be able to individually program. Ex. a 5,1,1 programmable thermostat will have the same program settings on Monday-Friday and will be able to individualize the programming on Saturday and Sunday. A 7 day programmable thermostat will be able to set a different programming schedule for each day of the week.

Use with Heat Pump

Indicates that this thermostat is compatible with heat pumps.

Use with Heat Pump
Yes
Power Method

Indicates if the thermostat operates electrically on batteries or power from the furnace/air handler.

Power Method
Hardwired
Millivolt

A "2-wire Millivolt" system. These are usually gas-fired wall or floor heaters that do not have forced-air blowers. In other words, they are convection heaters.

Millivolt
No
Use with Gas/Oil

Indicates that this thermostat can be used with either a gas furnace or oil furnace.

Use with Gas/Oil
Yes
Use with Electric Furnace

Indicates that this thermostat is compatible with electric furnaces or air handlers with electric heater coils. The voltage to the thermostat will be the normal 24 VAC. This feature is different from a "Line Voltage Capable" thermostat which operates with 120 to 240 VAC.

Use with Electric Furnace
Yes
Programmable Fan

Allows for you to establish by schedule when you want your furnace/air handler fan to turn on and off automatically to circulate home air, even without your furnace or air conditioner operating.

Programmable Fan
Yes
Dual-Fuel Compatible
Yes
Resume / Adaptive Intelligent Recovery Capability

Brings the room temperature back to the programmed temperature at the set time, even when you may have manually over-ridden the program in the interim which will maximize comfort and energy savings.

Resume / Adaptive Intelligent Recovery Capability
Yes
ENERGY STAR® Qualified

Products earn the ENERGY STAR label by meeting the energy efficiency requirements set forth in ENERGY STAR specifications. The EPA establishes these specifications based on the following set of principles:

  • Product categories must contribute significant energy savings nationwide.
  • Qualified products must deliver the features and performance demanded by consumers, in addition to increased energy efficiency.
  • If the qualified product costs more than a conventional, less-efficient counterpart, purchasers will recover their investment in increased energy efficiency through utility bill savings, within a reasonable period of time.
  • Energy efficiency can be achieved through broadly available, non-proprietary technologies offered by multiple manufacturers.
  • Product energy consumption and performance can be measured and verified with testing.
  • Labeling would effectively differentiate products and be visible for purchasers.

Backlit Display

Allows easier viewing of disply screen in the dark.

Backlit Display
Yes
Outdoor Temperature Sensor Capability

When used with an outdoor air sensor, this features allows the thermostat to sense the outdoor temperature and indicate such on the screen. Also allows some thermostats to automatically decide whether to heat or cool the home based on outside temperatures.

Outdoor Temperature Sensor Capability
Yes
Indoor Temperature Sensing Capability

Some thermostats provide for wiring to an accessory called an indoor sensor. The indoor sensor mounts in the home living space away from the thermostat, and tells the thermostat what the temperature is in that area. The thermostat will then use the temperature from the sensor to indicate the home's current comfort level, instead of just the temperature near the thermostat.

Indoor Temperature Sensing Capability
Yes
On-Screen Help

Press the "Help" button to view an on-board instruction manual that gives definitions and directions for every screen.

On-Screen Help
Yes
