Electronic programmable thermostat with temporary reset
First Claim
1. A programmable thermostat for controlling temperature in accordance with program set temperature values, said programmable thermostat including a memory for receiving a program set for at least one of a heating and cooling mode, said program set defined by a plurality of time/temperature programs, over a daily period, each program including a program start time value, and corresponding program temperature values for each of the at least one heating and cooling modes;
- a manually selectable input element for initiating a change to the then current program set temperature value;
means responsive to selection of said input element for automatically re-setting the then-current program set temperature value to the highest program temperature value of the day when in a heating mode and the lowest program temperature value of the day when in a cooling mode.

Abstract
An electronic programmable thermostat having a program set made up of a plurality of program start times and program temperature values for a daily time period which can be automatically vacated upon initiation by the thermostat user. The user may initiate a temporary reset of the program time/temperature values whereby a microprocessor sets a new temperature value corresponding to a comfort temperature value obtained from one of the program temperature values. Preferably, the system automatically sets a temperature value equal to the highest temperature value of the program set temperatures, when in a heating mode, or the lowest temperature value when in a cooling mode. The system maintains such reset values until the beginning of one of the program start times depending upon when the reset feature was selected by the user.

9. A method of pre-programming a thermostat having a display, a plurality of operator selectable input elements, a memory for storing a program set of plural time values over a daily time period and corresponding heating and cooling temperature set point values, and a processor for controlling the thermostat setting of heating and cooling temperatures in accordance with the time and temperature set point values of the program set stored in memory and for temporarily changing the heating and cooling set point temperatures, said thermostat pre-programmed to perform the steps of:
-
responding to selection of at least one of said input elements to initiate a temperature set point change from the program set in memory; determining if the thermostat is in a heating or a cooling mode; setting the temperature set point value to the highest temperature value of the program set in memory when the thermostat is in a heating mode; and setting the temperature set point value to the lowest temperature value of the program set in memory when the thermostat is in a cooling mode. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A programmable thermostat operable in a program mode for controlling temperature in accordance with program set temperature values, said programmable thermostat including a memory for receiving a program set for at least one of a heating and cooling operation, said program set defined by a plurality of time/temperature programs, over a daily period, each program including a program start time value, and a corresponding program temperature value;
-
a manually selectable input element for initiating a temporary change from the program mode; means responsive to selection of said input element for automatically re-setting the then-current program set temperature value to a predetermined comfort temperature value selected from one of the program temperature values of the day.

19. A method of pre-programming a thermostat having a display, a plurality of operator selectable input elements, a memory for storing a program set of plural time values over a daily time period and corresponding heating and cooling temperature set point values, and a processor for controlling the thermostat setting of heating and cooling temperatures in accordance with the time and temperature set point values of the program set stored in memory and for temporarily changing the heating and cooling set point temperatures, said thermostat pre-programmed to perform the steps of:
-
responding to selection of at least one of said input elements to initiate a temperature set point change from the program set in memory; determining if the thermostat is in a heating or a cooling mode; setting the temperature set point value to a heating comfort temperature value selected from one of the temperature values of the program set in memory when the thermostat is in a heating mode; and setting the temperature value to a cooling comfort temperature value selected from one of the temperature set point values of the program set in memory when the thermostat is in a cooling mode.
