Upgraded installation of Evohome with UFH- HCC80R + extension, DT92 thermostats per zone, HW using tank and CH upstairs, all radiators with HR92's. The original installation was an "S" plan system. The pipe to the UFH has been joined to the "T" point after the original CH motorised valve. There are two BD91's one in HW circuit controlling the original motorised valve for that and one controlling the other CH original motorised valve. The UFH pipe then travels through house until it gets to another new motorised valve followed by the controller and pump for the UFH zones.
How should this be wired and bound? Is the plumbing correct? Do I need the CH motorised valve at all? Should I have a BD91 for the boiler?
The boiler is an Oil fired unit non combi.
Thanks for any help you can give me.
