ABSTRACT:
A cut-back thermostat construction having a thermostat arrangement and a timer carried by a housing in such a manner that the timer will cut back the temperature setting of the thermostat arrangement by moving an electrical switch of the thermostat arrangement relative to a temperature responsive switch operator of the thermostat arrangement when a predetermined time is reached by the timer. A movable actuator is operatively associated with the switch to be adapted to cause a certain movement of the switch relative to the switch operator when the actuator is moved from a first position thereof to a second position thereof by the timer when the predetermined time is reached. An adjustable member is separate from the actuator and is adapted to select the amount of movement of the switch relative to the switch operator when the actuator is moved from the first position thereof to the second position thereof whereby the adjustable member selects the cut-back temperature of the thermostat arrangement. A pair of spaced stops are carried inside the housing for limiting the degree of adjustment of the adjustable member and, thus, the amount of movement of the switch relative to the switch operator. The timer comprises a rotatable time indicating dial carrying an adjustable tab to be set at different positions therewith for selecting the predetermined time for adjusting the thermostat arrangement, the adjustable tab being snap-fitted to the dial.
