| 摘要 |
The present invention, in illustrative embodiments, includes methods and devices for reducing power consumption in a thermostat by adjusting pulse levels (duration and/or voltage) that are used to control an HVAC relay in light of variations of ambient conditions or other relay conditions. In some illustrative embodiments, an ambient condition is observed using existing thermostat features, such as, for example, a temperature sensor, and used to adjust pulse parameters.
