Multiple Circulator & Zone Valve Relays with Post-Purge?
Looked at a HW job yesterday with six circs and four zone valves. The control system for this looks like someone threw a whole bunch of spaghetti onto the wall and it stuck. Since we'll probably be re-wiring this, does anyone know of a mutiple circulator or zone valve relay that will allow the circs to purge some of the heat out into the zones after shutting off the burner?
