Is ThermGuard difficult to program?
ThermGuard uses a very simple single button programming method. The button is held down for 3 seconds to enter into programming mode. The button is then pressed for the number of hours to wait before turning on your fan or heating system. Once the hours are entered, the button is pressed to indicate the number of minutes to run. ThermGuard uses two LEDs to indicate when to enter hours or when to enter minutes.
