Rapid programming of thermostat with multiple programming mode conditions

摘要

The invention provides for a controller such as a thermostat for an HVAC System comprising a housing having a circuit board and a display screen, the display screen having at least one alpha-numeric icon and a group of input control areas. A microprocessor is provided for control on the display screen. Buttons are pressed in order to program set-points of the thermostat so that seven days may be programed simultaneously. The display includes a seven-day icon so that the user can program the thermostat set-points rapidly (e.g. setting time and temperature settings with minimal steps). The user may activate a first programming mode wherein the activating occurs by depressing a programming-mode button for a first pre-selected duration in order to select a first day for setting the conditioning mode. The user may activate a second programming mode wherein such activating occurs by depressing the programming-mode button for a second pre-selected duration that is longer than the first pre-selected duration in order to select programming for all seven days simultaneously.
