HVAC integration and AI scheduling
Engineering approach for integrating chilled-water FCUs, split systems and district cooling with a smart-home controller.
Best practices
- Zone by occupancy pattern (bedrooms vs living vs guest)
- Pre-cool 20–30 min before typical arrival
- Use vacant-mode with humidity ceiling, not setpoint alone
- Meter and expose bill impact so clients trust the schedule
Common mistakes
- Placing the thermostat on an external wall
- Assuming Wi-Fi thermostats work without additional wiring
- Ignoring minimum airflow requirements when zoning
- Setting aggressive vacant-mode setpoints without dew-point check
Engineering checklist
- FCU / IDU model + protocol confirmed (Modbus / analog / IR / cloud)
- Thermostat mounting location free of solar gain
- Return-air sensor available or planned
- Empower / district-cooling meter access confirmed
- Zone map matches occupancy zones, not room count
Recommended workflow
- Mechanical survey
- Protocol + wiring plan
- Thermostat placement design
- First-fix cabling
- Integration + zone commissioning
- AI schedule seed from occupancy data
- Bill-impact review after one billing cycle
