I have the 2023 release Vaillant Ecotec Plus 832 installed (touch screen display at front). It was installed with a Wolseley Centre wireless controller however the radiators were taking 50 minutes to 1 hour to come up to the target flow rate of 60 degrees and after much misdirection by Vaillant...

I have had Viessman Vitoden 200 for ~6 years. Have had almost no issues with it, works brilliantly. However the central heating has stopped working in the last couple of weeks. The boiler seems fine, no fault code, green light, hot water good etc. The only problem I can actually see is that the...

Hi Everyone! I have a rather old integrated dishwasher, Whirlpool ADG 7470/2. As of recently it refuses to work, showing "6 flashes" error code. Perhaps local experts could help me figure out what is going on. Here is what I know so far: (1) "6 flashes" apparently means that the dishwasher...

My Vaillant ecoTEC plus 618 display is always illuminated - previously it would go dark until I turned one of the temperature setting knobs. Not only that but now the temperature shown is flickering irregularly around the preset temperature (70°) and also flashing back to the outgoing...

Does anyone know what's inside a Danfoss TP2 and what voltage it works at? My guess is that it's just a thermistor. Also wondering if the programmer supplies it with high/low voltage (dc or ac?) . I've used Arduinos for Internet control of various sensors in the home, so if I knew the...

Hi everyone, I am currently getting some renovations done to my house so the builders took down the PIR sensors. Since then I get constant errors on tampers etc so I haven't been able to use it. They are now ready to put it all back again but have managed to lose the back plate on one of the...

Hi all, New member here and in dire need of help with my alarm. I have set it all up myself and has been working perfectly fine for years, however I now have the added complexity of having a dog in the house.... When we leave her alone in the house (downstairs kitchen and lounge have PIRS) she...

I have a sealed magnetic contact connected to the Accenta Gen4 on my wooden shed door, I replaced it with a sealed metal contact on previous advice near 2 years ago. Previously I used the standard white plastic contacts and even tried a heavy duty contact for a gap that is always near enough...

Dear all, My Combo van has started to display the external temperature much higher than it used to. Today, in January, it displayed 35C....probably wrong! My questions are twofold: 1. Where is the sensor located? I suppose it must be at the front to avoid engine heat, but a quick scan of that...

Hi, My polo has caused me problems from day one and I was wondering if it was maybe time with me to part with it... The current issue at the moment is my engine management light has come on (this is the third time in about 4 months), I have had my front O2 sensor changed twice in that time and...

Hi all, I currently fit Pyronix systems, but last couple I've done the PIR sensors wasn't that responsive when alarm is set. They learnt with no problem at all & signal strength was good. Anyone had this issue? Regards, Chris

Hi, I'm hoping that someone out there might be able to offer some advice? I've recently moved into a new house and had an ADT Smart Home alarm fitted. I discussed with the sales chap that we would be replacing the front door shortly and asked about moving the sensor when the time came to which...

Hi Everyone, I'm in the process of programming my new alarm, its a Texecom Premier Elite 48, with 32XP Expander. I've managed to get the system to learn the PIR sensors, i'm struggling with the door contact sensors (Impaq Contact-W), the control panel isn't able to find them. I've shorted the...

I need to replace 4 sensors on a zone that occasionally false activates. I have bought Honeywell Activ8 AM-DT anti mask quad PIR and Microwave sensors, but they appear to need 8 cores back to the panel. Because this is a retrofit, I only have 6 cores. The installation instructions refer to this...
