Editor's Notes
- Controlled Device Considered Fan Operations: 4 position switch 3 windings on one core Switch selects either a winding or off position Implemented through relays 3 control relays is in parallel with switch Remote/Manual select relay
- Manufactured controls: Electrical switch Control Through module: Similar to fan control Implemented through relays Status detection scheme similar to fan’s
- How to interface the digital thermostat with microcontroller
