1. A digital thermostat having a user input means for raising or lowering the temperature setting, the thermostat comprising:
- a battery for powering the thermostat;
a processor having an input port pin for connecting to an external device to receive initial time and date information at the time of production of the thermostat;
a memory means for storing the initial time and date setting received by the processor;
a real time clock that is set to the initial time and date setting and subsequently maintains the actual time;
a switch means for switching the processor to a low power usage mode that disables all thermostat operation with the exception of the real time clock function; and
a restoration means for restoring the processor to normal operation, in which the processor prompts the user to select a time zone from a set of time zone settings; and
a display means for displaying the local time information.

Abstract
A digital thermostat having a plurality of user input buttons, a display, a battery, a real time clock, a memory and a processor that is capable of receiving initial time and date information and storing the information in memory. The initial time and date information is then provided to the real time clock for maintaining the current time in the thermostat. The user is prompted by the program to select and enter a time zone setting, after which the current date and local time is automatically set and shown on the thermostat display.

8. A thermostat for controlling a climate control system, the thermostat comprising:
-
a battery for powering the thermostat;
a connection means for receiving an input signal of time and date data from a device external to the thermostat;
a memory for storing the time and date information;
a real time clock for subsequently maintaining the current time setting after initial input of the time and date information; and
a display means for displaying time and temperature information, and a processor for controlling the thermostat, where upon activation of the thermostat, the processor prompts the user to select a time zone and responsively provides the display means with the day and local time setting for display. - View Dependent Claims (9, 10, 11, 12, 13)

14. An improved programmable digital thermostat comprising:
-
a battery for powering the thermostat;
a processor having an input port pin for receiving an initial current time and date setting from an external device;
a memory means for storing the initial time and date setting received by the processor;
a real time clock that is set to the initial time and date setting and subsequently maintains the actual time;
