There is only a speaker and it doubles up as the internal alarm sounder and the door chime. Why a speaker with a pcb? Are you able to control the volume with that type? Can you recommend one? Cheers

Tested it today and it hasn't made any difference to the alarm internal sounder, the chime is slightly quieter. Sparkymarka Can you recommend a suitable Texecom speaker please.

I've just found the engineers guide online which is quite comprehensive and followed the instructions, I was previously looking at a general user guide. It was only set to 2 , settings are 1-9 cant imagine what level nine is like, thats heart attack territory. I wiil try an alarm test tomorrow...

Yes it is painfully loud. I've had a couple of FA actuations and sods law it always happens in the early hours. Thanks for the advice, I will follow your instructions, fingers crossed.

Picture of the sounder. Hope this helps

Hello everyone, I have the above house alarm. Can anyone tell me how to silence the internal sounder, don't won't to isolate the door chimes or the external sounder and strobe just the internal. Many thanks I have the Engineers code.

Glad they eventually found the fault on your boiler, you're correct this is the same flow switch, the engineer explained it was a swinging valve inside which was stuck in the open position due to corrosion, he found the fault initially using a multi meter. the previous occupier was with BG and...

It's a condensate system boiler, I have a mega flow pressurised system.

Potterton Promax 24 HE

Just thought I'd give an update as it's nice to know what the 'problems' were when posting for assistance. Went with the B Gas fixed price repair £99 and the homecare 200 cover. First call was to clean the existing sensor and ignitors, seemed to be ok but he decided to replace with the latest...

It says Promax HE on the front of the boiler

Thing is Ian about a week after he completed the service I was looking through a few forums and came across a thread about the seals on the Combustion door had a light bulb moment and thought that may be the problem. Got to be honest observed the service and replaced the seal it was not...

Yes, and he failed to mention the fact the combustion chamber seal was barely intact, this is an accredited engineer, maybe he was just having an off day.

Sorry just thought there are probably a few variants of this model.

Really appreciate the reply, two of you mentioning the electrodes so I will arrange for them to be changed, Can either of you provide a part number ? Cheers

Thanks for the reply, He just cleaned the old ones, so that would look like a probable cause. Cheers

Would really appreciate some assistance. Intermittent fault where my boiler is not firing up every time with call to heat from CH or HW. Boiler has been serviced, the igniter cleaned, the CH and HW actuator heads and valves have been replaced, still not fixed the problem. I would say the problem...

Hello Terry, And that has finally solved the problem. God only knows, As I have changed three of these damn things before and never had a problem, a moment of stupidity. Thanks for all your help, and patience.

Hello Terry, It does look like the M/V pale blue wire on the new Myson CH actuator is connected to the earth wire in the terminal 3 from left highlighted with blue dot, which it should not be I am assuming it must move along one and connect to the same yellow wire as the HW Actuator blue, if...

So I replaced the Myson actuator today, had my fingers crossed turned the room stat call for heat and the bloody main RCD which cuts all the power tripped again, the exact same happens if I remove the brown wire from the actuator terminal 2, this stops the RCD from tripping (see pictures of...
