Y PLAN HEATING - WIRING DIAGRAMS - HOW IT WORKS - EASY TO FOLLOW STEPS TO UNDERSTAND Y PLAN SYSTEM

In this LearnElectrics video we will look at the wiring method of the Y Plan central heating system.
This follows on from a previous video that looked at the wiring methods adopted for the S plan system.
As you will see in the video, the two modes of operation are quite different.
The Y-Plan system remains a very common system, many millions of them have been installed over the years and you will come across them often. It uses only one 3 port valve, comprising one inlet and two outlets, and the system will allow for hot water heating and room heating together or individually.
Some popular questions about Y Plan systems …
How does it do this? How can we follow what is happening in the circuit? Are the thermostats different, How do they work? What is a wiring centre? …
… and so many more.
We will look at the various parts that make up the system, look at how they work and then build up the whole system and see this working in several different heating phases.
This is video number 198 and to view all our videos type in LearnElectrics all one word into the KZbin search bar.

Great explanation David. I've watched every single video you've made and have gained a wealth of knowledge, great videos for any up and coming apprentice sparks, so clear and concise.Many thanks for taking the time to make them, much appreciated

[@learnelectrics4402]

That is brilliant feedback John, thank you. Thanks for watching and spread the word. Dave.

[@sports872]

Excellent video again. Hope they keep coming. Interested to see what comes next. They're always on good and useful topics.

[@learnelectrics4402]

Thanks for the feedback. I think its two wire four way lighting next week.

Thank so much! This is one of the best presentation and illustration on how a Y-Plan system operates. Keep up the good work my friend. No pun intended but there are 000's of installers who do not fully understand how the Y-Plan or for that matter even the S-Plan system functions. They simply connect wires to the terminal blocks.

[@learnelectrics4402]

Nice of you to say so. Thanks for the great feedback, appreciated, Dave.

[@johnkeys368]

Excellent video as usual ,thank you.

[@learnelectrics4402]

Glad you enjoyed it, thanks for watching.

[@brianhewitt8618]

excellent 👌

[@learnelectrics4402]

Thanks Brian.

[@CarlGuymer1]

Very good

[@learnelectrics4402]

Thanks, appreciated.

You should write a book on all this information in this series Using the format in this series

[@learnelectrics4402]

It has been suggested before, and I should take a serious look at it. Thanks for the nudge. Dave.

Fantastic one David! Thank you! May I kindly request a video on how to interpret electrical drawings please? I just struggle to comprehend most of the time- especially when I’m on a construction site. Just feel lost to be honest! Your help would be greatly appreciated! Cheers again.

[@learnelectrics4402]

That could be a good idea, thanks. Dave.

My heat only boiler only has 3 core cable dangling down from it. Baxi said you can't wire inside the boiler. Also the pump wires need to be joined at wiring center.Can you advise haw to feed boiler from wiring center?

[@learnelectrics4402]

Refer to the manufacturer's specific instructions. They will have a wiring diagram on the website that you can compare to what you have, which numbers in the wiring centre relate to your exact boiler.

Hi - any idea why there would be a link between the L and 1 ( Com) on my programmer - or put another way would it cause any harm if I copied this when replace a Centaur TC1 with a hive dual channel programmer? Thanks.

[@learnelectrics4402]

Follow the manufacturer's instructions. Sometimes copying wire for wire can lead to problems. Identify what the wires are on the old programmer and then compare to the new programmer. Dave.

[@b67874]

Thanks Dave@@learnelectrics4402

[@trevorbyford]

Great job - One mistake I think at 10:48 where you say the "Pump sends 240v down the orange wire" where it surely is that the 'Valve sends 240v'?

[@learnelectrics4402]

There's no catching you out Trevor. Well spotted, I'll correct that typo, or is it a wordo? Thanks for the support. Dave.

[@martinburgess2322]

👌😎👍👍👍

[@learnelectrics4402]

Thank you Martin, appreciated.

[@shiamjad]

Thats very complicated compared to S-Plan

[@learnelectrics4402]

Oh yes. Hope the video helped. Dave.
