Running two digital rooersion, allmstats...?possible?

[ineedhelp229]

Hi Guys,
im a newbie. I recently discovered this site and have been reading and reading...very interesting.

here is the thing.
I have a combi boiler fitted in a normal 3 bedroom house with an extension and loft conversion, all with rads.
thee roomstat is fitted in the kitchen diner room.
We dont use the centra heating on timer and tend to turn it on manually either by pulling out the notches on the analog timer or once in a blue moon it is left on continuos and the thermostat is left on at 20 degrees.

Q 1..Is there any timing/ roomstat product on the market that can run in synchronisation( one downstairs and one upstairs)...
by having this, this would enable me to turn the central heating of from up or down?

this probably sounds strange to you...please help

Q 2. Im thinking of fitting drayton trv 4 all over the house. are they advisable? any complications? where is the best polace to buy them from?


Thanks for your help

****** ? are you American Go for the Drayton TRV`s first. Have a look @ the FAQ here about auto bypass with TRV`s. .Then check out the Electrics forum for the 2 way control Check web for prices.

You can usually pick up brand new TRV4's on Ebay. They may be in the trade packaging, a box, rather than the shop blister pack. Someone is offering 10 of them for £125 at the moment, but I think that's too high a price.

I haven't seen any CH control systems that allow you to control one zone from TWO locations. However, if you didn't mind splitting the system into two zones (some plumbing work required) then you could have separate control over upstairs and downstairs heating, with programmable roomstats for each.

If you want thermostat control in two places you can connect two thermostats in parallel so either can turn the heating on but they can’t turn each other off. So if it’s turned on upstairs, you’ll have to turn it off upstairs. If you are looking at using wireless controls, you could, for instance, use a Danfoss RX2 two zone receiver which will operate with two thermostats but wired for a single zone. Simply parallel the RX2 zone outputs so that either thermostat will be able to turn the heating on. Again though the thermostats would only be able to demand heat, not turn each other off.

Another more conventional solution is to use a single programmable thermostat. This will control the house temperature through the day without you having to manually turn anything on or off but can also be used to turn heating On/Off manually if you wish. That, with the addittion of TRVs should give you ample control.
