Demand Response Summary

Lennox L40 thermostats supports Automatic demand response capabilities, participating as an OpenADR 2.0b compliant virtual end node (VEN) in the DR process. L40 also complies with requirements specified in California Building Energy Efficiency Standards (Title 24, Part 6 Joint Appendix 5). Using Lennox phone app users can enroll their Lennox L40 in ADR services with their Energy Provider. Enrolled users can activate/deactivate their participation in ADR at any time. When user opts to participate in ADR, L40 establishes a secure connection to Energy providers DR server and periodically retrieves/responds to demand response signals. L40 automatically adjusts desired control targets (SP) to configurable presets corresponding to demand response signals. Users can configure limits to these adjustments, based on personal comfort or savings preference.
