Honeywell programmer

[palmerelectrcal]

Called out because the Honeywell digital timer(does ch & hot water)
blew up!! They've recently had a new combo boiler fitted.. Which is temporarily connected to
a supply but the timer etc has been left disconnected!!
Plumber thought there may be a faulty/damaged cable, But no breakers/RCD tripping.and the new boiler operating fine now
it's fed straight off the ring.
i guess by switching either the ch or the water on constant I should get 230v on the relevant terminals on the honeywell
connecting block but now it's knackered I don't. Thing is if I fit a new one I could
have the same problem. Any ideas? Apart from send the plumber back after dissing all the wiring

If they have had a combi boiler fitted then don't worry too much about it as it will be wanting a single channel programmer now won't they.

depending of what combi they have might already have one on the front of it

? Only if the installer bought the programmer and fitted it, I've not yet seen one that comes preinstalled in the boiler, I've always had to fit them.

yes of course it comes separate but most installers fit them as there is nothing to wire up except LNE

And a roomstat unless it's got an integral wireless on in the programmer

Shouldn't the plumber of had a single channel programmer and thermostat or programmable thermostat installed by an electrician to comply with part L (conservation of fuel and power) when he fitted the new boiler.

lol half the ones fitted on contracts (the eco and whatever its called) dont even have room stats, they relay on the boilers internal pipe stat and they dont even fit a programmer

Oil Combi boilers can have a remote programmed HW as well as Heating

only pre heat other than that no

That kind of defeats it being a combi then doesn't it?

Just test existing wiring and change the room stat to programmable R/S. All you'll need is a perm feed to the boiler and a pair from the stat.
