It's certainly nice to have the extra cooling power of a window air conditioner, or the warmth of a portable heater, but typically these lack thermostatic controls. Here's the solution: just plug the portable unit into this programmable thermostat and enjoy the benefits of 5/2 weekday/weekend programming and regulated room temperature. Programming is simple, and can be performed with the thermostat in your hand, not plugged into the wall. Enter up to four separate time and temperature programs per day for heating and for cooling, with one set for weekdays and a different set for weekends. There are two
G13A button cell batteries (included) to maintain programming and clock settings when unplugged or during power failures, and the display will show "LO BATT" when these need replacement..
Advanced features allow you to calibrate this thermostat so it agrees with another thermometer in the room. You may also adjust the variation in temperature allowed before turning on your heater of air conditioner. And you can set it to display in either degrees F or C.
Note: Your portable heater or air conditioner must be the type that automatically restarts heating or cooling function after power is re-connected and have a 3-prong grounded plug. Read your owner's manual or check with its manufacturer.
