Abstract: A thermostat having a simple to see and use setup-setback visual indicator. One temperature control is used to set temperature while a second temperature control is used to activate the setup or setback. The second temperature control is offset from the body of the thermostat in the setup or setback mode to provide simple visual indication of the setup or setback.

Abstract: A thermostat is disclosed which has a moveable backstop in order to fulfill a requirement in many countries that a 3 millimeter contact gap be provided for the thermostat to qualify as an electrical disconnect. The thermostat is comprised of a setting wheel having a ramp formed thereon, a lever, a plunger and a backstop slidably connected to the frame of the thermostat. The lever contacts the ramp on the setting wheel and is moved by rotation of the setting wheel. One end of the plunger is in contact with the lever, the other end being in contact with the backstop. When movement of the setting wheel causes movement of the lever, the plunger is moved in an axial direction thereof, thus causing movement of the backstop. The ramp is positioned on the setting wheel such that the backstop is moved when the setting wheel is turned to an off position.
