How to re-bind a Honeywell DTS92E Thermostat & BDR91 Relay Box

Richard from The Smart Thermostat Shop.co.uk (formally The Evohome Shop.co.uk) shows you how to re-bind/re-pair a Honeywell DTS92E Wireless Thermostat & Honeywell BDR91 Wireless Relay Box (also known as a Honeywell DT92E).
These devices can easily become unbound if you press and hold the wireless relay box button for more than 15 seconds, so should be an easy fix following our video.
However, if your DTS92E thermostat has failed, you can buy a Honeywell Home DT4R to replace the DTS92E and will easily bind to your existing BDR91 here - thesmartthermostatshop.co.uk/...

Thank you. Clear easy to understand instructions. Why Honeywell make what should be an easy procedure so complicated is beyond me!

[@Starlyna823]

I had a council repair man come to look at it and he didn’t know what to do and asked me to call again today and ask for another engineer call out. I woke up cold and miserable and decided to just search for the product number on KZbin and this angel of a man popped up. I followed his video and now my boiler is back on with heating and hot water and I didn’t have to take another day off work waiting for the council engineer. Thank you

[@MWPHS]

That's really nice of you to say! Glad we have helped! :)

[@anthonyscott5395]

A sincere thank you for this. There are shorter videos on KZbin that don't go into this level of detail and so don't adequately explain how to get this thing working. I have bookmarked it so I can refer again. Honeywell have made this ludicrously complex for the layman.

Thank you so much. Couldn’t understand why the heating downstairs on the ground floor wasn’t working but was working on the 1st and 2nd floor. We have a thermostat for each floor. Followed your video instructions and can already feel the radiators warming up! We’ve been abroad in climates of above 30 temperatures and to return home yesterday evening to cold U.K. temperatures again was hard especially with the radiators not working! Video was easy to follow for someone who isn’t tech or gadget savvy!

[@terryc-d2693]

Straight forward & clear instructions. I cleared down the DT92E as described but nothing happened on the receiver when I held the button down (for longer than suggested, too). The units were new in January, replacing ones with the same problem i.e. not talking to each other/unresponsive which led to the central heating being constantly on unless I turned off the boiler. This is again the same situation. Are they duff or is it me?

[@MWPHS]

BDR91’s are really reliable, so I would say if they are failing in quick succession there is a wiring fault.

[@terryc-d2693]

@@MWPHS Thank you. I shall rattle the cage of an electrician.

[@neil-robb]

@@terryc-d2693 Did you ever find the root cause of the BDR91 not responding to your long button press when trying to reset? I have the same problem as you had

[@terryc-d2693]

@@neil-robb annoyingly no. But one possibility could be the permanent live wire to the base plate on the receiver wasn't permanently live. The feed was taken from the ch timer thing and the heating bods thought that because this was being turned off to prevent the boiler from continually running, the receiver unit was getting so confused it just packed up. Not a lot of help I'm afraid but it might be worth checking. Good luck!

[@brandon45136]

Thanks for this helped alot. Does the boilers front panel need to be set in any particular way ?

Many thanks for this!

[@ukfundraising]

Thank you so much for this clear explanation. I've rebound the thermostat and relay box successfully. But that has introduced two new issues - 1) the override for the heating doesn't kick in, and 2) for the pre-set time for the radiators the heating is very modest. It comes on but at a very low temperature. The thermostat reads 17.5 degrees and the target temperature is 21.5 degrees. The flame icon is visible, and the RFID very occasionally appears. Any thoughts? Could the rebinding have changed more settings? We've always had full heat or no heat in the radiators - no halfway point. All individual radiator thermostats are turned on and I've just tried switching them all to maximum but the override is not having an effect. Thanks.

[@MWPHS]

Unfortunately Howard you are asking us to diagnose your heating system problems with a crystal ball (joke)! :) It sounds like you have an issue not associated to the room thermostat, so this needs investigating by a heating installer. Just re-pairing the thermostat alone following the video we have produced would not change anything (as long as the video is followed to the letter).

[@ukfundraising]

@@MWPHS Thanks for this. Yes, that sounds likely. I'll call our contact. Thanks once again for this video - and also for replying to me and so many others over the years.

Hi, I follow your instructions and the red light goes out on the relay box, I then set the temp above room but then no green light. There is a wireless icon at the bottom but nothing happens. Can you help?

[@MWPHS]

If it is bound correctly as per the video, the thermostat and BDR91 should work. Have you tried removing the power supply from the BDR91 for a couple of minutes and then re-powering the BDR91 and trying again?

[@leebamenzies8031]

Thank you so much! You helped me!!

[@CupraBBD]

Can you have more that one connected to the relay box for example this thermostat and also the evohome?

Hi Richard - this is super helpful. I have a related question. Is it possible to pair / bind a DTS92E with an HR92UK - I have long curtains which cover the radiator so the HR92UK doesn't get the room up to temperature unless i set it to a much higher temperature than wanted.

[@MWPHS]

Hi, yes you can pair a DTS92E as a room sensor in an evohome HR92 controlled zone. We will have some videos covering this soon, however if you need support doing it in the meantime contact Resideo tech support on 0300 1301299 option 3.

[@solarrover9575]

Can I just replace the faulty stat (dts92), and pair to the existing relay box (bdr91)? Or should I replace both items? Thanks

[@MWPHS]

[@Kittygriffiths4619]

Hi in trying to fit one of these but when I press the two buttons for the installer menu and press down those options you show at the begining do not show on my stat, I can only press up not down. Pressing up leads to different options that does not go to the ones you show on here.

[@MWPHS]

Neil Griffiths this is a wireless DTS92E and only the wireless version will have these menu options.

[@PaolaM-p4t]

Should the green light on the relay box be always on ?

[@BDonTJ]

Great video. Thank you. Question! What may cause the receiver unit to show a RED light and the system to fail?

[@MWPHS]

Normally a loss of comms between BDR91 and DTS92E. BDR91 too close to metal objects is the number 1 culprit.

[@BDonTJ]

@@MWPHS Thank you so much for responding. The BDR91 *IS* close to the hot water tank and various pipes but all has worked satisfactorily for quite a number of years now. I did re-bind as per your instructions and have kept the DTS92E in an adjacent bedroom as a temporary measure. The connection hasn't dropped again so I'll try moving the sender unit downstairs again soon. Thanks again for your VERY helpful video instructions. 😃

[@maggiehebblethwaite]

How do I get the thermostat box off the wall to bring it to 2-3 meters from the rely box please?

You shouldn't need to physically move them closer, the distance stated is to ensure the devices are not too close to each other. :)

Is there a difference between the DT90 and DT92. I have a new DT90 which I am trying to bind to replace a broken one.

It will allow me to press teh up arrow but then I just get ot, cr pb etc. Am I missing something?

[@MWPHS]

The DT90 is a 'wired' thermostat (not wireless). The '2' in older Honeywell thermostats denoted that it was a 'wireless' product. I hope that helps?

Is the relay box a must for this thermostat to work ? Soryy if this is a stupid question but i know nothing of how these things work 😊

The thermostat in this video is wireless, but the one your son has is probably a DT90E. This might help ( support.resideo.com/s/article/Where-can-I-find-the-user-guide-for-the-DT90E-thermostat?language=en_US ).

Sometimes, you have to turn the thermostat all the way down and then all the way back up again. Also make sure the thermostat is set higher than the room temperature. If you need support, call 0300 130 1299.

The power button should turn the heating off. You need to bear in mind the thermostat is only one part of a heating system and if the other components are faulty, then it won't matter what you set the thermostat to, it might still operate? Obtain a local heating installer to come and check your heating system for you.
