hi, firstly. i am qualified to install unvented but have never been asked to do one before. old system is y plan so can i simply add a zone valve in the flow to the unvented cylinder? also the cylinder stat doesn't seem to have a click on/off point as it only goes from 60 - 90 degreees so will this still operate the valve the same way? cheers.
