Hi

I wrote before about upgrading my existing 3 zone heating system to Evohome I have 3 Heating Zones with a Zone Valve associated with each one no Hot Water zone

The System I was playing with before I have now installed in my Daughters Apartment and it works great 3 Zones all with HR92s and Evocontroller as Temp Sensor in Living room Zone

I am now going to do my own system I was wondering how to deal with existing Zone Valves if I decide to go all HR92 Route do people normally latch them open or wire them into Boiler Demand Relay so they always open when Boiler is on

Or if i decide to keep zone valve on one zone with a Temp sensor for that zone can this be done

thanks
