Hi all !
Could I ask some assistance please..I have a fully pumped system using a Netaheat boiler, honeywell v4073 diverter valve...cylinder stat and room stat.
Im updating the controls from a standard rotary room stat with a switchmaster sm400 programmer to a horstmann centaur c17 programmer and stat 7 room stat..As the wiring seems different from old to new could anyone point me to the correct diagram please?
Thanks!
