Yeah space for 4 lives in one terminal and 4 neutrals in the other terminal and yeah the cables are the spur which goes through a fuse

Hi, got a fused unswitched spur which I want to replace for a newer better looking but it has 4x 2.5mm wires out the load side, I can’t really seem to find any spurred fuse that accepts more than 3, has anyone encounter this problem before?

Okay thanks for the results, I think I’m gunna try putting a delay timer between the pump and controller, the controller never turns the pump off so I’ll use the timer to force the pump on and off, maybe 15mins on and 30mins off or something like like Then I can see if the temp climbs

144 litres? It’s written on the tank in bad handwriting lol, yes I think AUX is attached to the top of the tank near the outflow, where it is normally hottest. It does not control the pump, but is usually the one whose temperature is shown in the display; LOW is attached to the middle of the...

I’ll monitor it closely tomorrow but I’m sure the pump constantly runs, the display only shows one temp which I believe is the AUX sensor (on instructions) which I think is the top of the hot water tank , I cannot see the collector temp other than manually read with multimeter, I’ve had it on...

Tried swapping connections but the pump was on at night and the dif test didn’t work so I’ve definitely got the wiring correct, Im sort of coming to the conclusion that maybe where the tubes are old there just not very efficient maybe, or the controllers just bad. do you get yours serviced or...

I’ll give it a try and report back, and nope no motorised valves in the system

I dunno as there is a “test” button on the controller (12 on instructions) when I switch that, pump comes on like it says it should?

Hmm okay from my research this is a very old controller, 90s electronics inside maybe 80s maybe worth noting the tubes are rather old I don’t have an actual install date but definatky older than 2011 so probably not as efficient as yours, I’ll change the settings as you said and continue to use...

All I’ve managed to find was this I was under the impression the differential was the difference in tank temp vs the solar panel temp So it does increase maybe about 5° an hour? Once it hits 30° it’ll increase slowly but if I have my boiler on and the tank temp will be maybe 70° the pump will...

I’ve tried it at all sorts, but 4° is what the recommended is by the manufacturer

So i think the pump will run untill a preset temp is reached I have an adjustable knob (30-80°) and a differential control (1-10) I’ve got it set about 50° so it’ll run constantly untill that temp is met this could be sunrise to sunset depending on the tank temp

Yeah thanks but it’s for the garage so I want the metal clad switch to match the rest of the sockets

Most of the wiring has been replaced except two lightning circuits and one of the socket circuits, it passed an EICR a couple of years ago so I don’t think it’s necessary yet Rewiring that one circuit will be alot of work so probably wise to get all the old circuits done at the same time, so...

Fortunately the one I need an earth for has a junction box above it with the L N E connections which leads to the light, so I’m just gunna run the earth from the switch to the junction box, I’ll check there’s continuity and resistance, I know the rest of the lighting circuit is correct as it was...

Hi, My lighting circuit had cpc added at a later date but none of the switch’s have cpc going to them just the lights Wanting to add cpc and Just wanted to check, the light switch earth will just connect to the light cpc?

Sort of resolved it- NTC probes are fine, opened up the controller, changed all the caps and the transistors and checked relays, two boards were connected via screws which I’ve swapped out for link wires as I suspect a poor connection. The temp is still a little sporadic but no where near as...

Okay so there’s a test button which doesn’t seem to do anything and a DIF test, when I slide this the pump kicks in and sounds like water is flowing, when I test both at same time the pump is on but the temp display disappears, There’s settings to adjust the degrees and the differential(1-10)...

Yeah reads normal, 1.5 bar

Hi, Got solar hot water tubes on the roof, don’t know much about them but they don’t seem to operate correctly, when there turned on the raydan controller temp display is very sporadic and jumps around and occasionally the relay which controls the circulation pump is constantly clicking on and...
