Hi guys..
We have a honeywell 3 port valve and horstmann cylinder, wall stat and programmer which was fitted recently..spent a week looking for a heating engineer to do the work but all too busy, so a sparks mate of mine came around to fit these with me..both heating and hot water now work...
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...
