Active Solar Thermal HVAC System Control
Endecon renovated a custom HVAC
control system for a home in Hayward, California that had been built with integrated active solar thermal features in 1980. The original control system was a unique design implemented with wire-wrap prototyping
methods that were not aging well after 20 years. The old sensor and control wiring design was reverse-engineered, re-routed, documented, and a fully documented controller design was installed using a
C-programmable PLC (programmable logic controller). More information is available at here.
