Hi Guys.

Got A Bit Of An Odd One Here. I Have A Customer Who Has A Seven Zone Boiler. Each Zone Has A Two Wire Thermostat Control. He Wants To Replace These Old Controls But Dosn't Want To Place A Set Back At Each Location. What He Wants Is To Be Able To Control All Zones Sepratley From One Location. My Only Thought On This, Being As Im Not A Hvac Man Was Possibly To Install An X-10 Wireless System Back To A Computor Control Any One Have Any Experiance With This Type Of Install. Appreciate Any Thoughts.
Thanks.
 
IMHO, x10 is only really suitable for household and very limited commercial use (conference room light control, that sort of thing). Why does he want to replace the existing wired system? Also, if the x10 fails to turn on the boilers and a pipe freezes, who has to deal with the consequences?

If there's already wire in place, there are many control systems that could use the older wire. You probably want to visit an HVAC supplier for some ideas. They may have some wireless systems, too.

Thanks For Reply. This Is Residential. Tryed Talking To Him About Standard Set Backs But He Want To Control The Entire System From One Location. Plus Old System Is A 2 Wire System Most Set Backs Require At Least 3 Except For Battery Ones.
 
Can you replace the wiring? If so, consider a networked communicating thermostat system, such as this, which I'm pretty sure (but this is from memory - check!) can be setback from one location. If theres a need for even more control intelligence, then add a Stargate.

RCS do an X10 version of the thermostat, which might actually be OK, and would save changing the wires, as all the thermostat wires go back to a single location (where the boiler is), and are almost certainly on the same phase, so the X10 signal paths should be good. But I don't know if it does the full range of functions that the wired versions do. Neither do I know if it needs the third wire for neutral.

If you do go X10 then stick a whole house X10 blocker in the panel to make sure that next door's X10 doesn't interfere with this house. This used to mean a choke, but now theres a much neater solution, see here.
