ESI Programmable Room Thermostat Instructions | Step By Step Guide 

Just about to attempt to set mine... Wish me luck!

@@lyndachabane1931 honestly, going by this video, you can't really go wrong 😁

Thanks Paul - Glad you found it helpful.

In addition to what you have said...the smaller buttons and slider are difficult to manipulate when you are older and have thicker fingers with less dexterity of movement. Please, please...can the designers and manufacturers start taking account of this for their older and/ or partially disabled customers customers.

The best explanation I’ve heard/seen for a novice such as myself to understand this step by step guide good & clearly shown with excellent diction thank you

Glad we could help!

Hope it could help!

Definitely not what you need 😅

U can find the guide online but it’s confusing. This is much simpler

Glad we could help Tom!

Thanks for the feedback Chris

Hey Michael, thanks for making this clear for people dealing with the same issue 🙌

Thanks so much for this feedback 🙌

If it's just for one day then you'd be best putting it into manual mode when you wanted it on, as AUTO mode would set the thermostat to bring up your scheduled on and off times.

That's what we aim to do! Don't forget to subscribe for more no none nonsense talking.

Thanks Sukki we're flattered!

Hey, thanks for your comment. The only options you can use with this thermostat are a 5/2 day split, 7 day or 24 hours. Your best bet is changing it each week on the 7 day setting if you really want it set on a schedule.

Hey Carol, glad we could help!

This is what we want to do!

Hi, the best way to do this would be set a P5 and P6 time at the same times, so that it goes 'ON' and 'OFF' at the same time.

@@Heatable Thanks for your reply!. At the moment, I am still tentatively using the mannual setting on 23 degrees, and then just turn it down to 5 degrees after four hours. In the video around the 6:50 mark you briefly mentioned that using manual mode all the time isn't the most cost effective way of running it. Could you please explain why? I find manual mode much easier to use and would like to know if using the programming cycles is more energy efficient.Thanks

Hi Denise, yes if you don't wish to have the heating on over the summer months you can simply switch it to the 'OFF' position to turn off any schedules you have.

Typically you can use P1 P2 P3 etc to decide on what temperature you'd like your home at what times. This doesn't always mean on and off as you could decide on times in the day where it stayed at the same temperature for P2 - P4.

You're at a loss? I moved into a house with one of these awful things. 😢 As a former Hive user which was super easy to use, I find this plastic contraption too fiddly! 😢

If you have your programme set up, the heating should be kept in programme mode unless you want it on all day, you can switch to Auto or manual override.

What programme is your heating set to? The reset button is the tiny one under the cover, on the far right.

These are the best instructions to follow to set up a schedule: support.esicontrols.co.uk/wp-content/uploads/2022/05/esrtp4-_user-instructions_web.pdf

Some of the other ESi controls including their 6 series can be upgraded to a smart thermostat by purchasing the additional ESi Controls WiFi hub - they don't advertise this as an option for the 4 series though.

I also can't work this out😂x

@@abbiehunstone8141 I found this video. It’s so complicated for such a simple thing but this worked for me. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-pRDL6GEQLJ0.htmlsi=hptcwqYYeQ0GHiXJ

The setback temperature (used in Auto mode) is the P2 and the P4 setting. Setback simply means that rather than turning the heating off while out or asleep, maintain instead a lower (setback) temperature, in order to keep the house structure warm. Typically, used in older, poorly insulated houses (such as mine) to keep the house structure from getting too cold during those periods.That way, when the heating turns to the higher setting (the P1 and the P3 settings), heat is used to heat the room and you, not the walls, which have been kept warm by the setback temperature. I use this in my 100+ year old house and it keeps me more comfortable. If you don't want or need to use this feature, just set the setback temperature (the P2 and the P4 settings) to a lower figure, so that the heating does not need to come on. If you decide to go to bed early, and therefore do not need to keep heating at your higher temperature, this is when (in Auto mode) you press the - button to set the temperature to a lower one. The programmer will use that manual setting until the next programmed setting, when it will revert to Auto mode. Similarly, if you arrive home early, simply tap the + button to your required higher temperature and the system uses that setting until the next programmed event. Setback is not used in manual mode (when the slide switch is in MAN mode) since you always set the temperature. You could of course set it manually to 16 degrees. If you want to turn the heating off (fully off, for the summer), set the slide switch under the cover to OFF. My understanding of the instructions is that by default, this sets the system to FROST setting, which would only turn the heating on if the temperature drops to the pre-set frost temperature.

@@choir74 This is really help information. I recently purchased a boiler that requires the use of this thermostat and couldn't for the life of me figure any of this out. Thanks for posting a detailed comment about the settings. I also wondered, if I leave the thermostat set to mannual setting, and turn the temperature down to five degrees, is this essentially as good as switching the boiler off?

I so agree with you. Rubbish indeed! Hive is better!

Hi John, is your thermostat new out of the box?

There should be 6 events that you can programme so this would give you 6 different time changes / settings a day. If yours isn't showing this we'd recommend getting in touch with the manufacturer with any questions tech@esicontrols.co.uk.

It's hard to say what's going wrong without seeing your full settings, what are P2 and P3 set to? This might be worth speaking to EPH about - 01280 816868.

The thermostat will have an internal temperature sensor to adjust the temperature of your home.

wishing you luck 😅

Mine did. I wouldn't have known if I hadn't got up to go to the toilet.

Unsure which symbol this is?

This may be a boiler fault or wiring issue. If you see the flame and the light on the receiver switches on then the fault will likely be with the boiler

Have you been in touch with ESI? I would recommend speaking with them if it's suddenly stopped working and you've tried reseting it and changing the batteries!

no yet, thanks! try to buy better battery@@Heatable

Please can you confirm what ESI thermostat model you have?

And I’ve also adjusted the temperature to the lowest setting (5) but the heating is still warm, what am I doing wrong ?

Same

Your installer will connect your thermostat to your boiler for you!

​@@Heatable The kids broken have ours, if I buy one of these how do I connect it to my boiler or does it automatically connect to my boiler?

@@Junier_Hussein Most of the thermostats will come with a how to guide for setting it up, it won't automatically connect, some need to be wired etc. If you're not sure then we'd recommend that you contact an electrician to get it set up safely for you.

@@Heatable Thank you much appreciated, I bought one and easily got it connected.

Sorted. Just changed the battery 😊

@@growqueen glad to hear you've got it sorted, thanks for updating us!

Glad to know we did a great job 😂

Sorry to hear that

Do you mean your thermostat is no longer working/ signalling to your boiler?

@@Heatable Yes that's what I meant but fixed it now. I found video on how to pair them back

That's great 😊@@willwillwill5624

@@Heatable I'll share a link with you on how to fix it as you're the only people to eve bother replying

Thank you, it'll be helpful for anyone that might also be experiencing the same problem! @@willwillwill5624

Glad we could help.
