Brilliant response time. I have literally spent weeks looking for the solution but was even then not sure if I was correct. It's a workshop alarm which has been going strong for a few years but the bellbox got a bit tatty. Anyway, many thanks for your reply, it really is appreciated. Bernard

Decided to replace my old bellbox with a Reson8 one. Unfortunately the markings are different. Panel markings are TR +12 0V Bell- STR- Bellbox RTN- HOLD OFF+ HOLD OFF- TRIG STR- I "think" the connections between the two are the same sequence as above, but not sure by any...

I posted it because I was fed up with WB's extortionate prices for spares. Thanks for the U Tube video anyway, part of the learning curve. I will look at the Vortex switch to see the price difference. Thanks. Been thinking of fitting a pressure switch instead of the flow switch. Anyone...

Fed up with Worcester Bosch spares costs. I have just replaced the flow switch with one from RS Components, got it on eBay for a fiver. The Worscester switch costs in the region of £70 but a new one of these from RS costs £35 and FAR better quality. Works a treat. Minimum flow rate is 3...

Yes, that is the one. Seems clearer now though. The PSU is marked "IN" and "TV" so I now assume I connect it in any of the four outputs with the "TV" side connected to the TV end of that output coax. The PSU will also supply the masthead preamp to boost the other 3 outputs. It's all...

Fitted a Megaboost single aerial in the attic a few years ago and it is really brilliant. Decided now to replace it with the 4 way aerial but the instructions are a bit confusing. It states that the coax from the aerial goes to the distribution box fitted on the aerial (marked IN) this is...

I have a Triton Domina Thermostatic Shower that I installed around 7 years ago. Over the last 12 months I have noticed that temp drops when other hot water taps are used in the house. It's off a combi system. Also the stat is not as responsive as it used to be. I am thinking along...

Will do that and report back. Thanks a lot.

Pressure was checked when I drained some of the system to give me no pressure on the boiler gauge. With 0 pressure on the boiler gauge, the vessel pressure shows just under 1 bar. With 3 bar (or near enough) on the boiler gauge, the pressure vessel still shows just under 1 bar. That is...

Just had my Heatslave 20/25 oil boiler serviced. Everything is OK except the system pressure, starting off from cold at just below 1 Bar but when system (heating) is up to temp the pressure has risen to just below 3 Bar. Checked the expansion tank and that seems fine with a pressure of 1...

Thanks for the reply. Also found confimation on past posts.

Easy question for a change. Does an Oil Boiler serviceman need to be OFTEC registered ? I had my boiler serviced this week and was told that OFTEC registation was not required for service, only for commisioning. I have been involved in engineering maintenance for 50 years, the guy did a...

I have a Canon Henley dual fuel cooker. The Top Oven/Grill fan will not switch off unless I fiddle with the Top Oven control (switches off when control is between Off and Lowest Temp. How do I access the controls to check/renew. I have not looked too hard but can't see any screws for...

I am considering geting a Clarke CR2 (2100 watt) 1/2" router. Don't have a lot of work for it so cost is a major factor. I have one worktop to cut for a sink so I assume I need a machine with a bit of gut. Any comments on the Clarke router ?

On the Scantronic 9452 there is (I think) only one Strobe Output marked "STR". I need to connect this to a Sonade 2000 bell box which has Strobe - and Strobe + terminals. I am assuming the Scantronic strobe output is - (neg) and will go to the Strobe - on the Sonade 2000 with 12v posotive...

Is there an alarm system on the market that can give me a combination of wired and wireless systems ? I need say 2 x PIR's and 1 door contact wired and 1 PIR wireless.

Crazy innit ? All this fuss about registration, Part P, 17th Edition, and they still allow people to create trashy work by design. :twisted: :shock: :( :evil: :roll:

Whenever a ceiling rose needs to be replaced with a light fitting it always seems to end up as a half sloppy job. Light fittings never seem to have the same fixing centres and almost never have adequate room for tidy connections. I usually end up turning a suitable wooden pattress on a...

Just found loads of previous bits of advice on this subject. :oops: :oops: Thanks for reading anyway.

What would be the best way to cut a worktop to length without the danger of chipping the surface edge ? I have a circular saw but not a very fine tooth. I was toying with the idea of scoring the worktop first with either a stanley knofe or a 1mm wide cutting disk and then cutting with the...
