Pepco MD TOU-P has different on-peak windows by season: summer (Jun-Sep)
14:00-19:00, winter (Oct-May) 06:00-09:00 and 17:00-21:00. Heat is gas, so
winter electric peak logic is cooling-only.
* pre-cool: bounded to summer (Jun-Sep); winter has no pre-cool.
* peak-setback (hold) and peak-ends (return): unified across seasons via a
season self-select (month -> season; triggers carry id: summer/winter and act
only when trigger.id == season) plus a params map for setpoints. Summer forces
cool + 82 / returns 74 daily; winter sets 82 / returns 74 ONLY when already in
cool mode, so it never disturbs the gas furnace.
* new ac_winter_morning_kill: 06:00 winter work days, if in cool mode set
hvac_mode off to dodge the 6-9am winter peak. No auto-resume yet (planned).
Decision logic verified as a truth table via the template engine across
summer/winter x cooling x workday before commit. Deployed in place (existing
ids unchanged); new id ac_winter_morning_kill added.
