Thank you Julian, great video presentation. This is exactly what I have, three wire (ground not used) Honeywell. I will go with Moesgo also as it has all the features I’ve been wanting as well.
*Works great: **Fastly.Cool** and Warming environment perfectly controlled. I use 3 in different grow tents. It’s nice to see from your phone how your tent temps are. Does High and Low and records data.*
Thanks for the video, you're a hero!!! I spent 3 hours trying to get this working yesterday, once I watched this it all made sense, really appreciate it.
I wired up my Moe's smart thermostat with three wires. Live. Negative. And switch return live . Thought it wouldn't work without a link to switch in but it works without.
I have 3 wires also Live Neutral and NO (normally open) on my old thermostat - wired them like this in the Moesgo but doesnt turn on the heating pump when it switches. Any ideas?
Hi Thanks for your very Helpful informative video.I have the same size white box as you are using and note that they are set into the box the screw holes to fix the back plate to.for the face of the thermo to go on.but how did you manage to slide it up and on.to hold it in place.....when the back plate is set into the box....thanks .presume its the same fitting....
To do the bridge between 1 and 4, is possible to use any cable? Anyway thank you for the explanation as I was unsure of buying the termostat as I have the same old of yours
Hi there i recently installed the thermostat exactly how you showed,but the boiler is not firing up. But when i put old thermostat it works please help me
This is helpful, but I'm still trying to find out if this type of thermostat can have a remote sensor? Our thermostat is in a up stairs bedroom that is often not heated, I'd like the sensor to be in our lounge. Would you know if there are remote sensors, or even if a smart-phone/tablet could act as the thermostat sensor?
Hi nice video. I have a horstmann thermostat which has 10A as switching capacity . Can I replace with moesgo smart thermostats which is only 5a switching capacity. Btw even it is three wires thermostat btw, so your video is helpful. Thanks
Thank you. Your advice worked an absolute treat. Now testing it out to see which wall is best to mount stat on!! 😊 By the way, if we wanted could we fit an NTC external temperature monitor to connections 5 and 6?
By the way, have you been able to use the scheduling feature? Whenever I set the temperature to change by schedule, it gets to that temperature and then stops triggering the boiler. I used 1mm square cabling by the way. Are we supposed to use 2.5mm square?
@@Subi_UK I've never used the scheduling facility, but would expect it to behave as you say, unless I've misunderstood you. I did use 2.5 mm cable, only because I had some spare and the run was around 3 metres. However it was a challenge terminating it inside the MoesGo , and its power rating was significantly more than required! I believe 1mm cable is rated around 5A ,(although that is dependent on various factors), and so you would need to check the rating of the equipment you have connected it to.
@@julianjones7914 Hi Julian. I ended up using 1 mm cable over 5 metres. Everything is working now. Still can't get over how good it is!! You can change the temp from your phone or using Google voice. The geek inside me is loving this!! Thanks again.
Great explanation very helpful. I am about to replace mine but at the moment there are only two wires and some others pushed into the wall. Do you know which wire (colour) I would need for "contact". I understand your explanation of the loop. Great tip about the screws Many thanks
Hi Julian. I have both the same old and new thermostat's used in this video. But my old Honeywell thermostat only has a live, neutral and earth going to it. How would I wire this into the Moe's?
Hi Julian, my old thermostat just had 2 wires, basically its a switch that closes a 220v circuit. I have no neutral. How would you connect in that case to the thermostat you show in the video, I have the same one. The thermostat powers up ok when I connect terminals 3 and 4 with a 220v feed.
Hi , I have a problem because it looks like everything is connected well , but when I want to turn on the heating, everything it's fine on the thermostat, but the boiler does not turn on the heating. I would be grateful for your help and advice
thanks. my current E91 stat has Live, Neutral and Switched Live. there is not a switched neutral. So i wont require a loop like you have described. right?
Hi there, I tried to install the same Moesgo thermostat to replace Honeywell old model; but the Moesgo thermostat does not seem to power up. When I went back to old Honeywell thermostat, it powers up. Any thoughts?
All I can suggest is to double check the mains wiring is connected to the correct pins of the Moesgo, and that the terminations are tight. Confirm with a multimeter that the live and neutral voltage is correct if you are competent. Check that you have adhered to the manufacturers installation instructions. You may just have a faulty Moesgo.
Julian, I'm still confused ! I've only got two wires and an earth going to my Honeywell type mechanical thermostat, one red, one black and an earth. I would like to fit a digital thermostat but, afraid I might get it wrong. Our bungalow was built in 1972.
My old thermostat is exactly like yours but it doesn't have the gray wire, only black and brown, what should I do? how to connect it to the Moesgo smart thermostat?
Hi. Yes the Moesgo is connected to a central heating programmer, although it is not scheduled to always be on. Of course, when the programmer is off, then the Moesgo cannot regulate the temperature!
@Julian Jones, you responded to @MrDanicu979 that your central heating programmer is not permanently on. So if there isn't a permanent live going into the Moesgo thermostat, I am assuming the Moesgo goes completely off so the display turns off so you can't read what the temperature is at times - no big deal for most people. More importantly I assume the Moesgo has a memory of all the settings you previously entered so it won't forget them when the Moesgo turns off and back on. And I assume when the Moesgo turns back on, it determines the current time by accessing the internet because it has no internal battery to remember the current time with.
Hi Julian. I have the same thermostat but am having issues. I have 4 wires and they are all connected right. But when the tmerostat clicks to turn on it does not route electricity to contact (port2) like honeywell did to port 3. It thinks it is on but the boiler does not switch on. Any ideas? I first thought it was broken. Got a second one. Same problem
Hi. I'm sorry, but without being there with a good multimeter, I can only suggest a process of elimination! Its quite possible to get two faulty thermostats if there is a batch fault. If you haven't already use an appropriate multimeter after rechecking the Moesgo settings to; test the continuity of Moesgo contact loop when its set to high temperature.; With mains power off test the continuity of the neutral and live wires to and from the boiler, via the programmer as necessary. Good luck.
@@julianjones7914 One more question. In your example, what did you do with the ground cable that comes from the boiler (yellow/green one)? Just not connect it anywhere?
Excellent video, helped me to wire up my stat. However, so far the only command I have managed to use with Alexa is to set the temp when it manual mode. ie Alexa set thermostat 19 degrees. Alexa does not recognise the request to switch from programmed mode to manual mode or any other commands. Has anyone figured out the correct requests that work with Alexa?
hi Julian i refer you to a similar installation video by LaymanDIY and similar jumper solution to the one you suggested. However if you read comments section on his video by one Jurij Avesenak you will see a more satisfactory explanation of how to use the thermostat which does not require a jumper. Any thoughts?
yes I agree. You shouldnt need the jumper as the connection is done inside the unit. I have set this up and I only have a neutral in N, Live in L and a switch live in NO that goes back to the boiler (via a 2 port valve) If you have 2 heating zones, likely a fairly new build, you probably have the same setup. Dont be fooled by seeing two wirles going to your existing Danfoss room stat, they are likely a live and switch live going back to your 2PV. This all now works for me. Ive simply relocated the new stat at the 2PV
Hi I have only 2 wires coming out the wall live and neutral and connected them into the right places but it doesn’t work I also did a dry love but still nothing can you help
Morning. Sorry but it is a long time since I did this so I cant advise further. It wont work with just two wires live and neutral , as the Moesgo needs live and neutral to function. I explained how to connect it all correctly this in the video, including looping the live wire.
Buy a small length of 1 or 1.5 mm twin and earth mains cable ( Wilco sell small lengths). Cut out a piece of the brown wire, and use it as the linking wire.
The back plate separates from the LCD panel, connected by a ribbon cable. Hence the backplate is screwed into the back box, and then the LCD panel clipped back into its back plate!

Will it work with old wiring

Sorry, but I cant assume the correct wiring colour is used! A multimeter would be best to determine !
@@julianjones7914 Thank You
i think you need different themostat with 2 wire come out like that. try honeywell DT90E czcams.com/video/at7YcFka9cQ/video.html
Hi Julian. I have both the same old and new thermostat's used in this video. But my old Honeywell thermostat only has a live, neutral and earth going to it. How would I wire this into the Moe's?
Hi. I have the same problem only live and neutral, what should i do?
For a 3 wire thermostat, would you not buy the "GA" version instead?
Hi Julian, my old thermostat just had 2 wires, basically its a switch that closes a 220v circuit. I have no neutral. How would you connect in that case to the thermostat you show in the video, I have the same one. The thermostat powers up ok when I connect terminals 3 and 4 with a 220v feed.
I cannot advise as I haven't proven this, but perhaps the dry contacts on 1 & 2 should loop the 220 volts back to operate the pump etc? Rgds
Hi , I have a problem because it looks like everything is connected well , but when I want to turn on the heating, everything it's fine on the thermostat, but the boiler does not turn on the heating. I would be grateful for your help and advice
I've got the GB model. but need some help wiring it in. can you help?
thanks. my current E91 stat has Live, Neutral and Switched Live. there is not a switched neutral. So i wont require a loop like you have described. right?
Im not familiar with the E91, BUT my MOESGO wiring schedule switches live.
06:50 does it make a difference if we loop terminal 4 to terminal 2? I've seen that in amazon comments
I have a old mechanical room thermostat and it only has two wires in 1 = live and in 3 =neural

Hello sir. This a very good video. one question though if you would be so kind to answer. Do you have a separate programmer that you set always on?

Please do the WiFi video - I'm flummoxed now
Its not easy to mount lcd screen after fixing backplate just because of the way it is made.
Mine only has a blue and brown cable 😭😭
You will probably have to measure the polarity and voltage of each of the wires with a multimeter to see what they are, and wire accordingly.
Rgds
Ughm…. Thanks
ahm hm aaahmm mmm ahhhmm......
Glad it was helpful 😷
You are very welcome!
My pleasure- I found it confusing initially!
Buy a small length of 1 or 1.5 mm twin and earth mains cable ( Wilco sell small lengths). Cut out a piece of the brown wire, and use it as the linking wire.
Where would you recommend getting such a small amount of brown wire for linking? cant find anything on wilko. Great video.
@@bradsimpson512 Walking around skip or building site , you can have plenty ^_^
The back plate separates from the LCD panel, connected by a ribbon cable. Hence the backplate is screwed into the back box, and then the LCD panel clipped back into its back plate!
The linking wire should be a minimum 1mm diameter, 240v rated.
It has to be 1 core or two core? Because I dont know where to find this type of cable
The Honywell thermostat had a small screw at the bottom of its casing.
Depends on the rest of the heating circuitry! I would not be allowed to advise you.
Earth wire connected to the metal back box !
There wasn't a temperature probe with my thermostat.
Apologies but I cannot advise on different wiring without first trying the solution myself, and I'm not in a position to do so!
