The Ge LV systems were the rage in a lot of the "big" older homes. I know the units you are talking about, and serviced quite a few over the years. Unfortunatley, I have NO parts left. I'll mention it at a association meeting, and at the supply houses if anything is available
Yes, the ones I worked on used the same relays. You turned the dial to the numbered/lettered zone, and hit the button.
Had a few houses with a master in the Master Bedroom also.
