This unique programmable outlet thermostat allows 5-day/2-day control of window air conditioning units and portable space heaters. The PSP300 provides two separate programs, one for heating and the other for cooling. Each program has separate settings for weekdays and weekends, and every day the program cycles through four independent periods. Thus, during the time periods you set, the air conditioner or space heater will turn on and off as needed to maintain the desired room temperature.
This device can help reduce your energy costs if your existing window air conditioner or space heater does not have integrated programmable control and is capable of automatically resuming operation after a power interruption. The PSP300 plugs into a standard 120 volt 15 amp 3-prong grounded outlet, and the air conditioner or space heater is then plugged into the PSP300.
