Price Response

If your utility offers a Price Response Program, this thermostat works with your Energy Utility to inform you of the rate in effect at any given time and automatically adjust your energy use for each rate. The rate in effect is indicated on the thermostat display as shown (Critical, Hi, Med, and Lo). This typically involves controlling your home at a higher temperature during cooling season and a lower temperature during heating season to reduce energy consumption.
