REMOTE CONTROLLABLE THERMOSTAT

摘要

A remote controllable thermostat has an on-board power supply with batteries, a microcontroller having a timer, a temperature sensor, a temperature set point control controller and an RF receiver. The thermostat also has HVAC state control means for generating HVAC control signals in response to sensed temperatures being outside of control set point range and for periodically connecting and disconnecting the RF receiver from the power source to conserve battery power. Where the thermostat has user mode selector switches, the microcontroller is further programmed to read their state only periodically for additional battery power conversation.

1. A remote controllable, battery operative thermostat comprising,
an on-board power supply which has at least one battery, a microcontroller having timing means including time based set points, temperature sensing means, means for setting temperature control set points, a radio with RF receiver means connected to the microcontroller, said RF receiver means periodically controlling said radio between a high powered, active state and a low powered, passive, quiescent state, and HVAC state control means connected to the microcontroller for generating HVAC control signals in response to sensed temperatures being outside of control set point ranges or in response to changed control states.
