Copy feature (from day to day), as well as permanent and temporary hold mode, reduces programming time and makes it easy to use.
Accurate temperature readings - to +/- 1 degree in Fahrenheit and Celsius - for ultimate consistent control.
One-stage thermostat that works with gas, oil or electric furnaces, central air conditioners, 2 wire hot water systems, millivolt systems, central heating and cooling systems, and heat pumps without auxiliary/backup heat..

This non-portable water expansion tank is for closed loop hydronic heating system piping to control the thermal expansion of hot water and maintain system pressure below the relief sett of the relief valve.
The carbon steel tank is pre-charged at 12 psi, has a 4.5 gallon volume, and features a durable expansion membrane preventing minimizes loss of the air change and ensures long and trouble-free life for the system.
Made of carbon steel with epoxy finish, mounts to supply piping, with 1/2 inch MNPT system connection and .302-32 inch charging valve connection for on-site charging of the tank.
Maximum pressure 60 psi and can be used in residential or commercial hydronic heating systems.
Use in tandem with your hot water heater to absorb increased water volume ensuring long and trouble-free life for the system.

Display is Large Enough to be Easily Read from Across the Room.
Transparent Polycarbonate Faceplate with Straight-Forward, Easy-to-Use Buttons to Manually Adjust the Temperature Up or Down.
Accurate Temperature Reading to +/- 1 Degree F for Ultimate Consistent Control.
Designed with Style in Mind to Enhance the Décor of Any Room.
Perfect for New Installation or Replacement.
Universal Replacement- Replaces thermostats for 1-stage gas furnaces with electric or gas fan, 1-stage oil systems, 1-stage heat pumps, and 1-stage cooling systems.
Not compatible with base board heaters (or other line voltage heating), multi-stage heating or cooling systems, or 3-wire hydronic systems. Refer instruction manual before use..
