Abstract:
1. A system of a wirelessly programmable thermostat and a wireless programming module having a minimized user interface comprising: (a) the programmable thermostat comprising a first microprocessor effectively connected with a first input/output unit which in turn connects the first microprocessor to an environmental sensor, environmental control equipment for controlling environmental conditions of a conditioned space, a user-visible display screen, a user input interface, and a first wireless communication module, where a first control program operable by the thermostat microprocessor thermostat is adapted to compare a sensed environmental condition of the environmental sensor, compare it to a pre-determined setpoint, and to operate the environmental control equipment if the sensed environmental condition is outside of a range determined by said setpoint; (b) the wireless programming module having a portable housing with pressure sensitive buttons presented to a user and comprising a second microprocessor effectively connected with a second input/output unit and a second wireless communication module, where a second control program operable by the a user detects that a user has pressed one or more of the buttons and thereafter signals are transmitted by way of the second wireless communication module to the first communication module and the first control program causes a change in said setpoint or other thermostat function for control of environmental control equipment; (c) the wireless programming module lacks visible indications or displays observable to a user that any button has been pressed.
