Honeywell Home DT4R Wireless Thermostat - First Look & Review!

[@honeywellhome]

Thank you for your detailed review of our new DT4R! Glad you like the new features!

[@MWPHS]

We really do and we can’t wait to review the new HCC100 Underfloor Multi-Zone Controller!

[@gavinkiely5467]

Looks new and modern. Hopefully they might finally upgrade their app and bring that into the 21st century too. But this a start in terms of modernising it.

[@kimclewlow6054]

Please could you post a video of how to use and what setting your boiler should be on as I can't seem to get ours to work. Thank you

[@vincentohanlon]

Ah. I just installed a load of the older evohome stats!! Still good to know Honeywell still care about this stuff and hopefully we get some updates on the app (e.g. Showing which zone is currently capping for heat)

[@solpcb]

"Tado" My initial thoughts.. I'm sure you know already centre brand 340017 is also compatible with intergas boilers.

[@MWPHS]

I’m aware the CB stat works, but not a big fan of promoting the competition, hence we sell this - theintergasshop.co.uk/home/99-cms927-7-day-wireless-programmable-room-thermostat-cms927b1049.html We do sell it cheaper to trade to match Wolseley pricing too! :)

[@Suepalmer42]

Please can you make a short video showing lay person how to operate the thermostat once it is installed. Eg. What are set temp adjust buttons for / what is eco mode in reality etc ? Plus/ Minus / Flame etc are clear but what about all the other functions? Thank you 🤔😊

[@MWPHS]

I'll see what I can do! :)

[@jeremylam9804]

Hi there, I hope you can help me. My DT4 is blinking with error code “F 22”. I can’t find anything on the web about it. Do you know what it means? Cheers

[@MWPHS]

I don't, but Resideo technical support is on 0300 130 1299.

[@markg6320]

Hiw does the battery life of this new DT4 conpare with the old DT92E please? Will it be c2 years as the display will not he on permanently? Many thanks

[@MWPHS]

We are told that the DT4 should have a battery life of at least 2 years with normal use.

[@markg6320]

Hi. Great to know that this product has launched and will pair with the BDR91 receiver. I have 2 different rooms of underfloor heating on the same zone but with separate DT92E thermostats/BDR91's controlling the manifolds so i can have different temperatures in the 2 rooms but not different timings. Im thinking of installing witeless T4R unuts in each room to give mire control over timings/temoeratures during the day etc. Would the T4R pair eith my existing BDR91 receiver like this new DT4 product please or do i need 2x new receivers? And if i do need new receivers will the wiring be the dame as for my existing BDR91? Any help will be much appreciated. Al the best. Mark

[@MWPHS]

Hi Mark, as I have replied in one of your other comments, T4R is not compatible with BDR91's.

[@alexojus]

Hi, I'm looking to replace my two thermostats, one wired and one wireless. I came accroos the DT3 but can't find the difference between the DT3 and the DT4, do you know? And also, DT4 and DT4R? I believe it's the difference between wireless and wired but no clue for DT3 and DT4. Thanks

[@MWPHS]

DT3 is a retail product made for Amazon/Screwfix and DT4 is made for us as a trade seller. Comes down to if you want to support small businesses or support corporate organisations. DT4 comes in a few variants, wired (DT4), wireless (DT4R) and modulation (DT4M). Just to confuse it further, the wireless DT4R comes in stat only (DTS42) or with a wireless relay box (YT42). We then do our own version with a BDR91 wireless relay box (thesmartthermostatshop.co.uk/product-category/honeywell-home-evohome/wireless-thermostats/). The DT4M and DT4R (thermostat only) are only really used with the HCC100 UFH Controller (kzbin.info/www/bejne/fnu7f2ZtnJymr6c) or evohome (kzbin.info/www/bejne/qIiXZKqie9uKhrs).

[@user-uo1my8ee4k]

Hi,can I use this dt4r to replace my basic Honeywell room stat.only thing is when I opened stat there are only 2 wire,live an nautral.

[@MWPHS]

The DT4R is a wireless thermostat, so I am assuming you have the DT4? If it is a DT4, they are voltage free relay, not a live and a neutral. More information on the DT4 here... kzbin.info/www/bejne/iZi0ZHxtnqeNatU

[@user-gh8nf4yi5q]

Had the DT4 installed a few days ago. When the room reaches the set temp it switches off the boiler as you would expect BUT the boiler comes on about every 15 mins and runs for about 20 seconds and then stops. This is obviously not long enough to bring the room temp back up to its setting if it has dropped slightly. Is this normal?

[@MWPHS]

The DT4 is a TPI thermostat so yes this behaviour is normal when approaching and at room temperature, however the TPI algorithm needs to be setup correctly for the boiler you have, which is done in the installation menu of the thermostat (cycle rate, minimum on time and minimum off time). You can contact Resideo for more help and information on 0300 130 1299.

[@BIGBOY140497COD]

Can you program it for heating to come on at certain times?

[@MWPHS]

This thermostat is a non-programmable thermostat when it is stand alone. If you use it with evohome, the timings are all programmed through the evotouch controller.

[@user-mn6sf1fn9e]

Just had DT4R installed. When you press the centre button is the temperature shown the current room temperature. If so how do you set the required temperature?

[@MWPHS]

Yes when you press the centre button it shows the room temperature. Simply press the plus or the minus button to set the temperature you want.

[@hobb29]

Installed the DTR4 but setting required temp did not work. I press the + or - buttons and it fails to go up or down. The - button takes it straight to 5!! I simply want to you use the DTR4 like my old manual Honeywell thermostat where zi turn the knob left or right to switch o or off the boiler but it failed, so frustrating so reinstalled the old one again

[@derekjohnson3445]

Same happened to me , unfortunately this video is no help@@hobb29

[@Chris-hy6jy]

I'm after a dual channel, heating and hot water programmer with wireless room stat that supports multiple schedules. For example if i work shifts i need a schedule for days in and days off. Any recommendations?

[@MWPHS]

Drayton Wiser Kit 3? thesmartthermostatshop.co.uk/product/drayton-wiser-thermostat-kit-3/

[@Chris-hy6jy]

@@MWPHS that has two stats, I only need a single stat but I want the ability to set a schedule for "days on shift" and a schedule for "days off shift". I should then be able to select which of the two schedules to run by either selecting them from the stat or phone app. Can the Drayton do that?

[@MWPHS]

@@Chris-hy6jy OK, so maybe Wiser Kit 2 or T6R. Check out our thesmartthermostatshop.co.uk website! 👍🏻 Not sure any thermostat can run different shift patterns tbh, but it possible to do with 3rd party integrations like Home Assistant. 🤓

[@Chris-hy6jy]

@@MWPHS thanks. I've just ordered a Drayton RF902. I'm not bothered about accessing it via the internet so this seemed like a decent option.

[@MWPHS]

@@Chris-hy6jy good choice! Drayton Digistat RF902 can be used with Bluetooth to make setup easier. We have a video of the installation of one in the near future!

[@nickclement]

So will this pair with the DT2R wireless receiver? As the wireless thermo unit went walkies.

[@MWPHS]

Hi, yes it will do as the DT2R receiver is an OEM BDR91.

[@nickclement]

The range on it is awful, 3 floors down and it shows a 0 upon test. Fine if close but no way near the 30m range. Wondering what a decent upgrade (wi-fi) would be?@@MWPHS

[@MWPHS]

@@nickclement all depends how the relay box has been installed? Appreciate the following link is about evohome, but some of the rules apply to the DT4R too (see section 'things to consider when installing wireless controls') - thesmartthermostatshop.co.uk/evohome-help-guide/

[@MWPHS]

@@nickclement all depends on location of the receiver? Its on 868mHz so better than your average stat with regards to range. Maybe have a look at this - thesmartthermostatshop.co.uk/wp-content/uploads/2014/12/Things-to-consider.pdf

[@JaquiF1]

Please could you do an idiots guide of how to use these. Thank you.

[@MWPHS]

Yep, no problem. Added to the future video list.

[@darren.hilldrup]

Hi I have a four wire 6360 can I fit this two wire new DT4 wired thermostat??

[@MWPHS]

Yes you can and we have a video that will show you how imminently being relapsed on our channel!

[@derekjohnson3445]

Please could you do an idiots guide of how to use these. Thank you.

[@MWPHS]

We will see what we can do!
