My apologies, further explanation. The fellow who redid the system was knowledgeable, to a point. I had thought to use the original 2 wire t-stat for one zone and a 3 wire programmable for the 2nd zone. I went in the hospital for scheduled surgery. When I came home, he called and said he didn't know how to hook up the wiring for the valves and t-stats. The supply house sold him a W-R 1361-102 and a W-R 1311-102, but he only got the instructions for the 1361. These show a 2 wire t-stat. I sent you the instructions for a 1311, which shows a 3 wire t-stat. I should have looked at it better. Try this,
