Pool and Spa Controller

Pool and Spa Controller

The picture shows one of the control panels for a pool and spa controller. This was a distributed control system that could have multiple control panels in the house and multiple controllers in the yard for pumps and valves. The modules talked to each other via a shared RS485 network. The system was in production for a decade at tens of thousands per year. We got a lot performance out of a bunch of 8-bit microcontrollers! In retrospect, the best part of this project was:

  • Excellent project management.
