Thank you. I've left the existing timer on the always on setting now.

Thank you. All wired up now. The two connections from the boiler to the actual thermostat for controlling the on/off is basically terminal 1 and 2 which by default has a loop wire basically triggering the boiler to always be on unless it's turned off either using timer or the off button on the...

Does the ESRTPRF thermostat have a timer function or can I not switch between the thermostat and built-in timer? Probably won't use the timer and just use the thermostat once that's installed

I have a potterton titanium 40kw combi boiler that doesn't have any room thermostat at the moment, curently it's running on timer. I've got a ESI ESRTPRF wireless room thermostat that I want to wire up. Can anyone help me on how this is wired up to this boiler please?

Batteries could have been pulled out but the Sounders were never installed and invoiced for the job as a completed job. I had a look at the job sheet and the notes, it mentions the installation locations of all smoke detectors and heat detectors and the call point and no mention of any Sounders...

Yes seems like no sounders were ever installed as it's a small shop and I think batteries were originally probably also not installed hence why the wires are going down the bottom by the battery area.

All the companies we've called over just want to rip-off and change a perfectly working system and don't want to even touch this. Seems like a right rip-off. At the same time they are perfecty happy to come and do tests and issue certificates but not willing to make the connection. So my plan is...

A friend of mine has C-tec CFP702-2 fire alarm system in his shop. Recently a dispute led to some vandalism on the fire alarm panel. Basically the front cover was removed and the blue and brown wire that goes to the call point from the panel is disconnected. Picture below. And the batteries were...

After some heavy downpour on the flu wall my Main brand boiler stopped working and I can see some condensation on the LCD screen and it's flashing with error 110. I can see some water at the bottom of the cover. Any ideas what it could be?

Ahh sleeve nut. just googled that and looks like what I'm after thanks

I'm making a door flap that is to go and sit on a base-plate the two materials will have a hole and i'm looking for something that can go in the hole similiar to a rivet but that will allow the two materials to swing above freely around the hole. I was thinking some sort cylinder with a sort of...

Thanks for the replies. For my friends property, just out of curiousity a small 3 or 4 bed house in London how much should a complete rewire with new consumer unit typically cost London price?

Thanks for that. So just out of curiousity a new build this day and age that has new wiring, eventually at some point will the wiring need changing on that too?

A friend of mine's property has the old fuse wire type consumer unit. Part of building refurbishment to upgrade ceiling lights etc a company is quoting for complete re-wiring to change consumer unit. My question is, with an old system like that is a complete re-wiring needed? Does old wiring...

When attaching plasterboards to blocks using dot and dab, does building regs require the blocks to he rendered first? There is a cavity between block and outside brick with insulation. Just wondering if the internal blocks need to be rendered first? Seems like a waste of time to render then dot...

For the OT connection can I use any cable or does it have to be a certain type of cable? What kind of voltage etc will the OT pins carry?

Looking at the receiver specs of the EPH Combi Pack 4 wireless thermostat, the receiver spec says it's 10(3)A rated. Is that 3A or 10A? what kind of cable should I use to wire it 1mm2 or 1.5mm2?

I've ordered a EPH Combi Pack 4 Wireless Thermostat which I've been told is compatible with this boiler and it's opentherm too. Question regarding opentherm, is there a +/- wire or can the wires from the thermostat receiver's opentherm pins go in any direction to pins 1&2 of the boiler terminals?

So looking at the following installation guide: https://mediacdn.mainheating.co.uk/-/media/websites/mainheating/files/main-eco-compact-combi/main-eco-compact-combi-installation-guide.pdf Page 42, figure 35 seems to show the connections. I've found a wireless thermostat with opentherm...

Will you be able to guide me which page on the user manual refers to installation of the thermostat? From what I understand a thermostat essentially sends a relay activated switched live to the boiler telling it to turn in right? Could you guide me to the wiring diagram on the boiler end if...
