1. An RF controlled thermostat/controller comprising:
- the thermostat/controller including a microcontroller and a temperature sensor;
a superregenerative RF receiver which uses the temperature sensor of the thermostat for temperature stabilization of the superregenerative RF receiver while providing a very low power drain always-on receiver for RF remote control of the thermostat/controller;
a non-volatile memory for storing a digital value which is used is used, along with the temperature sensor output, to accurately tune the superregenerative RF receiver.

Abstract
An RF controlled thermostat/controller is disclosed for an HVAC system having a superregenerative RF receiver which uses the temperature sensor of the thermostat for temperature stabilization of the superregenerative RF receiver. The superregenerative RF receiver provides a very low power drain always-on receiver for RF remote control of the thermostat/controller. The thermostat/controller includes a microcontroller with a non-volatile memory. A digital value stored in the non-volatile memory, or a non-volatile memory of a separate component, is used in one of several different embodiments to accurately tune the superregenerative RF receiver.
