Honeywell T3-T3R Comparison T4-T4R, Differences Between Them, T3-T3r VS T4-T4R

[@pauldeakin3413]

Hi. I've watched some of your videos and found them very helpful. I've got a Honeywell CM927 on our heating system at the moment and it's been fine since the full heating system was installed about 10 years ago. The key pad is worn a bit now and it's hard to turn the heating up and down manually, which is really all we do. We don't use the automatic mode for pre set intervals. I found this video very helpful and have ordered a T3R to replace the CM927. Just want to say thanks really because we are on a budget and your video has got me to sort this out now at a great price on Amazon for the T3R after ages struggling with the old one so thanks very much and Regards.

This looks exactly like the centa thermostat. Exactly the same programming methods and buttons.... Thank you fantastic review.

[@colinmiller3474]

Excellent and very clear as are all Marks videos.

Very helpful video exactly what I was looking for. Couldn't find any videos showing the differences between the two thermostats as also no other video mentioned the boost function either which is exactly what I wanted.

Hi i have watched your video and now I can follow and understand how to programme a T3R I may have to readjust it as winter comes on thank you Mark.

My reciever unit has not only the usual mains connections however it has wires for the ABandC connections on the switched side.

Very very helpful video. Using the comparison button on retailer's website does provide a true comparison of the products, but your video did a very good job, thank you.

Thank you, very helpful. I’ll be getting the T3R I think - prefer the more straightforward option and don’t need more than 4 programmes during the day as were all out at work during the week, and can use the manual over ride at the weekend. 👍

A very useful video I have an old Honeywell thermostat, the CM927 but sadly, the display is nearly blank. It works OK and I can use manual mode without a problem, but obviously it is impossible to change times etc, so it is time for a new model. It looks like the T4R is the one I’ll go for Do I need an electrician, or a gas engineer to link this up with the existing receiver, situated near the boiler, or is it straightforward procedure.

Thank you so much you're star 🌟

Amazing!!! Thank you so much for helping to rebind my T3

[@omarsaid8258]

Very informative, thank you

[@davidjkstephenson4232]

This all looks very helpful in updating my old control system. Hot water is the issue; the current Honeywell controller includes this f feature but I also have the option use the immersion heater. I think its time to ask the serious question about gas boiler v Immersion heater, Gas v electricity, how do the running costs compare? Then perhaps I can have some advice about wiring the chosen system after replacing the existing Honeywell with T3R.

Very nice video Iam thinking getting T4

[@gilli3018]

Thank you,really helpful.

What's that logo in the right top corner doing/showing? It looks like a wifi.

[@lioneltheobald4369]

Hi can you replace a CM927 honey well with a goggle nest controller instead

[@TheZippyMark]

Am i right in thinking the T4 supports OpenTherm and the T3 doesnt'?

[@deadmanwalking1930]

Nice channel. Just curious though why is one showing 23c and other 23.5c ?

[@sanmonik05]

Hi thanks for your videos, those are really helpful. I have a problem with my thermostat I think it is T4 the temperature doesn't go down. I set it on 19 Celsius degrees and it is oscillating between 27 and 28 Celsius degrees What should I do. Thanks

[@MarkBallardLTDHeatingEngineer]

If the pin does not go up or down, you can gently tap it with a hammer, hopefully it will start moving move. Be carful it also might leak.

[@bilzwilz8294]

Won't my heating come on if its not set higher than the ambient temperature ??

[@nancydavalos1556]

Nesecito configurar mi thermostat t2

[@pinto154]

Heeft u ze ook in het nederlands

[@ponderer467]

I think t4 is much better as it has 3 separate on times

[@paullorentz1375]

As a gas engineer,,, We should not have heating on & off throughout the day, its wasting both energy and money.

[@aniamlodzianowska7622]

I. am afraid that I did not find this program useful, jumping between one and the other was not useful. I am still not able to set my T3R thermostat.
