A thermostat for controlling heating and cooling equipment of the type which includes a fan and at least one end device consisting of at least one heating and cooling fluid control valve, at least one electric heating apparatus and at least one air damper, said When the dial knob 26 is removed, an enlarged opening 38 reveals an exposed jumper which can be shorted for the purpose of initiating a test sequence to determine if the thermostat is operating properly. Once the test jumper is shorted, the test sequence is started by rotating the set point potentiometer fully clockwise to initiate the test without a changeover temperature test. It can be rotated fully counterclockwise to initiate the test with a changeover temperature test. The start determines if the room or air temperature is greater than 60 degrees F. and less than 80 degrees F.
