Replacing this 'stat & programmer (pic)....

[barki]

Hi,

I'll get to the point. The wife (obviously) wants to replace our thermostat (in Dining Room) and Programmer (in boiler cupboard).

Reasons - purely for improved aesthetics.

Pic of the Thermostat here;

Its a three wire job (one blue, one yellow, one red).

Pic of the Programmer (Potterton EP2001) here with lead annotations;

All she really wants is a funky modern blue-glow type thermostat like these cheapo ones on Ebay http://www.ebay.co.uk/itm/Blue-LCD-...arden_Hearing_Cooling_Air&hash=item3a879e7218(yes, i'm afraid, a blue backlight that glows all day and looks cool is important, even if it wastes some power!)


I believe we have two options:

- Option 1: Replace the thermostat on the dining room wall only with a cheapy modern one like the one linked above

- Replace the thermostat & programmer with something like this http://www.ebay.co.uk/itm/170947004042?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649.

I have a question for each option;

- Option 1: Why do some of these require batteries as well as a wired connection? Are these totally crap?

- Option 2: I believe, that that set would replace both programmer & thermostat. So we'd mount the receiver in the cupboard next to the boiler, hardwired to it, and hen mount the programmer (which incorporates the room thermostat function?) somewhere appropriate like in the landing? Presumably these remote RF modules need regular battery replacement. Are these crap, or difficult in anyway?

Is there any reason why my boiler would be incompatible with either / any other thermostat & programmer out there? I've got an old chaffertaux, which I'm hoping will solider on another year or two having just replaced a burst pump-heat exchanger pipe & sensor.

VERY graefull for anyones advice

Cheers!!

The programmer you have will need to be completely reworded as that programmer has all the wore centre in it so the starting point would be to remove the old programmer and fit a wire centre. Next thing is options you need a 2 channel programmer ( hot water and heating) and a thermostat you can do his in a few different ways. Twin channel next to whirring centre room stat in same location. Or single channel next to wire centre and a rf programable room stat/programmer where ever you want it. I would forget the cheap controllers of eBay. Rf packs we use Honeywell or hard wired we use Honeywell or danfoss. A bit of electrical knowledge will be needed to wire the centre or get a plumber or gas engineer in to do it for you.

You say to replace just the thermostat with one 'like' the one in the link.
Just checking you mean 'like' and not 'the same' as the one you have linked to is for underfloor heating.
