Customer Question

Hi tom... I have 1311-102 Zone-a-Flow water valves and I am trying to wire a Honeywell RTH6500 thermostat in place of the mercury three wire thermostat. I have 5 wire cable in the wall and used one as the C but I can not seem to get it wired right.

You can't use this thermostat with the White Rodgers 3 wire zone valve. You best option is a White Rodgers 1F80-0471 available here

There are no Honeywell thermostats that can be used with these zone valves
