Wall thermostat and the like
First Claim
1. A thermostat for an ambient air temperature regulation system comprising:
- a microcomputer having;
an accumulator,input/output channels coupled to said accumulator,a data address register coupled to said accumulator,an instruction decoder connected to said data address register,conditional interrupt lines connected to said instruction decoder,a multiplexer coupled to said data address register and to said instruction decoder,discrete input/output ports connected to said multiplexer,an arithmetic logic unit coupled to said accumulator,a carry flip flop connected to said accumulator and to said arithmetic logic unit,a random access memory module connected to said accumulator and to said data address register,a read only memory module connected to said instruction decoder,a program counter connected to said read only memory module and to said instruction decoder,a keyboard having a plurality of selector keys for providing manual inputs coupled to some of said input/output channels and to said discrete input/output ports,a temperature sensor connected to at least one of said conditional interrupt lines,a high frequency clock connected to at least one of said conditional interrupt lines,an electronic display coupled to said discrete input/output ports and to some of said input/output channels, anda remotely located thermal pump connected to said multiplexer for activation and deactivation by said microcomputer.

Abstract
Apparatus is provided for a wall mounted thermostat to accept and convert manually generated instructions to binary encoded electronic impulses to control ambient air conditions in the environment in which the thermostat is located. The parameters of operation include a building heating control which reduces the desired ambient temperature at night, beginning at a prescribed time and returning to a higher daytime level at a different prescribed time. The system may also adjust desired temperature depending upon humidity conditions and alter the timing of heating and air conditioning control by predicting when a desired temperature will be reached in order to avoid overshoot. The system includes a liquid crystal or light emitting diode display and communicates with a power source and with heating and air conditioning switches such as relays or contactors.
