the way you have it wired won’t do anythjng to the boiler. You basically have connected a wire that is not connected to anything

At the very least get a phase tester screwdriver, you can use that to check that theres no live on any wires before you touch them. It's not easy to check the terminals when the controller is in place, it covers them. Jumping live from the brown wire into 1 or 3 should turn the heating for either zone respectively. As its a zoned system with Zone valves, theres no direct connection to the boiler. Either of those black or grey wires opens a motorised valve for their zone, and the valves have relay contacts which close when either valve is opened, sending 220 volt live to boiler to cause it to fire up.

@ted1, he hasn't done that wiring in the photo, that's the wiring of the original timer backplate, which is mechanically identical to the backplate of the Wiser kit3, but uses different terminals because its wiring is configured as British Gas standard two channel controller, but Drayton use a different wiring plan in order to use the same baseplate for a three channel timer. That's why he needs to move the black wire from 4 to 1, then both wires will be connected to the Wiser's two CH terminals, 1 and 3, with HW on 2 unused.

I really appreciate all the help. I'll report back in the morning.

It's an absolute curse getting the screws into the bottom of the programmer as well.

Haven't done anything yet. Had Phoenix Gas out today to change the meter which was preplanned. They've said I've a leak. I got my new boiler on last Friday and could have sworn I smelled gas. I asked my wife, nothing. Asked nextdoor in and he didn't smell anything. Not happy I didn't trust myself and put it down to being paranoid. I'm going to buy a gas alarm I think now.

Curious… Have whole home HVAC units, which provides both heat and A/C, become a growing thing in Ireland? Just had mine replaced in the US. Went from a 2 seer unit that required Freon coolant (which is no longer allowed to be purchased in the US) to a 14 seer unit for efficiency and because my Freon was empty.

Just to report it worked. Thanks very much for your help.

I've got some wago connectors and will remove the thermostats next week.

Domestic home AC not a thing here at all, though with the higher and more prolonged summer temperatures as a result of global warming, there might be a market, if not for whole home systems, at least individual room through wall heating/cooling units. Ive seen these in Australia, and Ive seen these offered for sale here, they might be tempting if you've got some free summer solar power to assist in their operation, as day rate electricity here is pretty expensive.

Heat pumps installed here are almost exclusively for heating. Most units are capable of cooling, but i don't know if this happen very often, as the air to water heatpumps can cost €16,000 to install to your existing water filled radiator heating system. Cooling be another days work. And hardware cost. Their efficiency is measured in COP, not the US SEER or SEER2. COP, coefficient of performance, is a measure of the ratio of power input to heat output. The fanboys of heatpumps are ever present on the media claiming COP of 5, realistically 3 is the norm, and if the heatpump is under powered, in cold weather the COP will fall to 2 or less as owners futilely crank up the thermostat. (A mad woman was given prime time on the evening news the other night to scold householders for not installing heatpumps, "and solar panels to power them". 6 panels on the average semi might produce a kw out in winter daylight for an hour or two, and nothing after 4 pm, ideal for powering a 9kw heatpump. Not.

There you have it. A kind of Garron Noone guide to Irish heating for yanks, without the C and F words.

Thanks. LOL… Sort of reminds me of the book I'm currently reading "The Story We Carry in Our Bones - Irish History for Americans" by Juilene Osborne-McKnight.
