Hi folks, Thanks for taking a look here. We have a Worcester Bosch Greenstar 30CDi Combi boiler, and a Danfoss RX-1 unit as relay to it. Existing Wiring: From what I can work out from the wiring guides for the Honeywell BDR91 and the Greenstar, I need to do the following: I believe I've...

Morning all, I was hoping somebody could help me with a Nest 3rd gen installation please? My problem is that the Hot Water comes on with the Heating, even when it's set to off from the app. My set up was: Boiler: Vaillant EcoTec Plus 630 Tank: Megaflow 210l Programmer: Honeywell ST9400c...

Hi, All working well with custom home screen and text but how do you add a control device? I imagined I could just add a button to activate an output to open a gate or something but can't for the life of me find how to program it in? Is there any information on editing the whole thing? I know...

hi My Honeywell st9400 appears to be fried since a power cut yesterday. It's showing an internal fault and from a bit of googling that seems terminal. As it is I've been thinking of getting hive for a while but wanted to know if, as well as replacing the thermostat, does it also replace the...

Hi all, I'm installing a new Nest heating and hot water thermostat and I'm trying to identify the 'call-for-heat', 'common' and 'satisfied' wires in my existing Honeywell ST9100A hot water control so I can switch them to the Nest. Can anyone help please? Many thanks!!

Hey all, I've read numerous threads on here about installing Nest 3rd generation into the home (such as this good one - kudos to @stem). I'm really tempted to do this myself but my wife will kill me if I screw up the heating at this time of year! If anyone can give me some pointers, it would...

Hi, I have an old Honeywell analog thermostat in the hall way and the dial keeps falling off it. I am not sure if I have aligned it correctly when putting the dial back on. Is there a specific way of doing it? Also, what temperature should the dial read when the thermostat clicks on? Thanks...

Hi, I am about to install my alarm system to go alongside my CCTV system. I am going to install a good spec Honeywell system with autodialler and adjustable PiRs etc. However I would like to install ADT bell boxes at the front and back as they look visually more detering and nicer compared to...

We have the above alarm. Originally installed by ADT a decade ago, it used to text us when it went off but that feature hasn't worked since we cancelled our monitoring contract and had some dodgy alarm men come and reset the whole box (ADT didn't give us the engineers code when we left and...

Hi all, I'm at my wits end after a week of boiler woes. Last Sunday we noticed a smell of gas coming from the boiler when the heating came on. We immediately called the Gas Emergency Services and someone came very quickly and detected that there was indeed a leak from the boiler. He shut the...

Hi, I need some help please... I want to replace an Drayton analogue thermostat with a Honeywell digital thermostat. The issue I have is I am not exactly sure of which way to wire it up, the Honeywell product states it a two wire product, but I have 3 wires (Red (live) Blue (neutral) and Yellow...

Hi Guys, I am a little cheesed off as I have already done in 1 boiler PCB board which I will have to order in. My Set up for the ground floor is: 1x Vailant 637 boiler which does my ground floor heating and hot water 1x Honey well programmer 1x Honey well Room stat. and my system is Zoned...

Hi, I have just moved home and the new house has a Worcester 30 CDi boiler with a UP2 dual controller. I know it is an upgrade, from my last house, but it feels like a bit of a downgrade. In the old house we had a Worcester 28 CDi and a Honeywell CM927 wireless room stat/programmer. I believe...

Hey Everyone, I'm on the last part of replacing my old accenta 6 with the new Accenta Mini G4, pirs working, panel working, all tampers fine and lastly, just had to mount up and install 2 new sirens as the Accenta Mini G4 kept freezing with my old sirens. The issue I have now is with the new...

I'm looking at a Honeywell G4 metal control panel. It's the 8SP419A-UK, and I'm confused. I've gone through the entire engineer's manual and can't work out how to connect door /window contacts. There are eight security zones which feature two connectors each. There is also just one pair of...

Hi all, Just wondering if anyone could help me to figure out how to use a 24 hour zone on my Galaxy G2-20 whilst maintaining the ability to deactivate the zone when required? I have seen this done in a company I used to work for where the fire doors where monitored for breaches but one door...

Hello guys, I'm currently in the middle of refurbishment work and would like to replace my old Honeywell T6360B with something more decent if possible (ideal Nest but not too sure if compatible with my boiler) It seems to be only 3 wires are connected (see attached photo): blue wire -...

Hi All, I have a Honeywell/ ADE G4 alarm system fitted. I recently attempted to replace 3 of 5 PIR's with pet tolerant units. The first unit fitted and worked without any issues. When I fitted the second unit all the power to the PIR circuit seemed to have failed. I have checked the 20mm...

Hi guys, I've been scouring this site to find a solution, but can't seem to find anyone with the same setup as my T40! I want to replace the old stat with a programmable, all around better one with a timer function. My problem is I can't work out the wiring in the T40. There are a total of...
