White rodgers zone valve to digital honeywell tstat help.

The valves a 3 wire zone. With terminals C, 4, and 5 going to tstat. Not sure which should connect to which. Tstat has usual lettered terminals O, B, R, W ETC. It is compatible with the heat system as per manufacturer specs. HELP

Welcome to the forums.

I need the model number of that zone valve.
Not sure if that valve needs an intermediate controller.

Is this a new installation ?
Are there other of the same type valves in use there ?

Is this what you have.... emerson climate/Valves/Documents/Cat_06_pg0298.pdf
