How the system comes together
per-zone temperature and humidity sensing (sense)
thermostats and hub schedules (control)
zoned HVAC actions (actions)
energy-trend and seasonal adjustment records (operation).
What makes the delivery work
unoccupied zones set back within hard limits; primary suites exempt from aggressive savings; manual control always outranks the schedule.
Who it’s for
- Luxury Homes & Villas
- US or Canadian project owners working with an appropriately qualified local installer
The project challenge
- Independent HVAC zones can fight a whole-home scene.
What the system should achieve
- Keep each zone's schedule within equipment and comfort boundaries.
Recommended system architecture
- HVAC wiring/system survey → approved thermostat → bounded comfort schedule
- Use temperature sensing as context; freeze protection and equipment safeties remain with the HVAC system.
Equipment & ecosystem choices
- A thermostat selected through the manufacturer compatibility checker, with suitable sensors
- ecobee is a candidate for supported systems, not a universal thermostat replacement
Installation & technical requirements
- HVAC technician identifies voltage, stages, heat-pump/aux wiring and C-wire or approved power option before any purchase.
- Site acceptance focus: Keep each zone's schedule within equipment and comfort boundaries.
Compatibility & construction constraints
- The ecobee PEK is limited to supported 24 VAC systems; millivolt, high-voltage, dual-transformer, fan-coil and communicating systems need a different assessment. No savings percentage is promised.
- Supply thermostat wiring and plant-zone topology before recommendation.
Make it your own
- For multi-zone climate scenes, confirm room/door/zone counts, agreed controls, notification recipients and installation stage.
- Specific decision: Supply thermostat wiring and plant-zone topology before recommendation.
Preliminary equipment plan
- One approved thermostat per independently controlled compatible HVAC zone; sensors and power accessories only as specified for that model.
- Scale by the surveyed scope for multi-zone climate scenes, not by a fixed package advertised without a site schedule.
What shapes the budget
- HVAC type, zone topology, wiring, technician work, power provision and user comfort limits.
- Country/city, labor, taxes, shipping, warranty route and confirmed supply source; no price or stock is assumed.
