Thermostat assembly
First Claim
1. A thermostat assembly comprising:
- a housing assembly;
a plurality of switches mounted on said assembly for selective operation by the user;
an indicator mounted on said assembly for signaling to the user;
a circuit unit mounted within said assembly and interconnected to receive signals from said switching means and to deliver signals to said indicator;
a temperature sensor mounted within said assembly and responsive to ambient air temperature to deliver a temperature-representative signal to said circuit unit;
connecting means for coupling said circuit unit to an external device to be controlled in response to operation of said switching means and governed in response to said temperature-representative signal;
a cover openably secured to said housing assembly in a position to overlie said switching assembly and said indicator;
a switch operator included in said a plurality of switches and facing said cover;
and means on said cover disposed in alignment over said switch operator and movable in response to pressure applied to said cover by the user to actuate said switch operator, so that depression of said cover will actuate only said switch operator to send a signal to said indicator.

Abstract
A programmable thermostat features a memory unit receptive of unit values of temperature desired at different times on different days all individualy or in various combinations both as to days and times. An output device signals a temperature control system. As controlled by a clock, the memory unit is addressed during different times of the different days to provide a signal representing the corresponding value desired. Existing temperature level is sensed and compared with each value so as to develop an error signal. In response to that error signal, the output is operated in a direction to reduce the difference between actual and desired temperatures. Numerous details as to layout, construction and circuitry are presented.
