I succumbed to temptation and dumpster dived a skip outside a neighbours house to see if there was anything technical in it. It was mainly junk, but there was a Honeywell two port valve in it, so I thought it would be interesting to take apart.
The little correction I made in my schematic of a Type-S heating system was to take the pump/boiler switch feed directly to the live rail. If I'd left it as I originally drew it, then one valve actuating would have back-fed the other valves in the system and prevented them from turning off until everything else had turned off.
Not a bad diverter valve. Rugged construction and quite easy to change the motor. If changing the switch take a photo of it first, and note that the motor has to be removed to remove one of the switch screws.
Here's a link to the video I made about the three port Y-system valve.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

Reminds me of the 24vac one that ElectroBoom took apart and fixed in his house.
One of the reasons for the rubber ball valve is that it is very low friction to operate. The motors do not have a lot of torque so the quarter turn water valves have to be very easy to rotate. The metal parts often need freeing up though! This is noticeable if the boiler does odd things and one will find that the zone valves are not opening and closing correctly.
Many of us would like to see you check out the motor internals.
I’m 2 years late, the brown is not a permanent live, the brown gets its power from an external 240v thermostat. The grey is your permanent live. Orange sends 240 to the heat source (boiler) and it fires.
Your hands are very close to the bare terminals of that quick connect. Im sure you can take it but it was making me a bit anxious 😂
Very interesting Clive I haven't looked at the date of this video but I was wondering I used to work for a few air conditioning companies doing warranty on new air conditioners the ones with circuit boards not contactors I was wondering if you can pull apart one of them circuit boards and have a look my old boss reckons that with all their Spain fangled gidjerwhats they claim they can go from 0% RPM to 100% rpm but there are always consuming 80% of the full rated current or 80% of the 80% normal running current
i've been working at a plumbing and heating place dealing with inventory and we seem to go through a ton of these things, so i was curious what's inside. when i say "go through a ton," i don't think these are usually the thing that fails. for example we go through a lot more in the winter because people's pipes are freezing and making a mess or it's the shoulder season and people are turning their heat on for the first time that year and something else in the system broke or rotted through up the line from them.
We have a motor that doesn't work anymore. Looking for a replacement. Ours says Synchron 660 240V 50HZ 5W 5 RPM and then some serial number 39413L-5-6-130. Are these easy to find? are they universal? where do you find one?
Wiring a three way valve, also known as a bypass valve, is exactly the same as wiring a two way valve, also known as a shutoff valve, as both valves in this design are drive open, spring closed. The valve is selected based on what happens to the water flow when the valve is closed; three way valves are used when the pump runs continuously and does not change speed, sending water around the coil or radiator, bypassing it when the thermostat is not calling for heat, where the two way valve just shuts off flow into or out of the heat exchanger and the end switch often signals for pump to start. In the US, hot water heating coils in the air stream of an air handler are common and the end switch can control the indoor fan in the AHU as well. Both two way and three way valves are available with different quantities and configurations of end switches.
I do have a short circuit on…. What can be? The motor or the switch?🤔
I am going to go to bed with this guy talking as I fall asleep
Very good video, I’m having trouble with mine and your explanation of how it works is very helpful 👍
Interesting, so you've covered Y Plan, now S Plan so how about the one for fat plumbers, Jane Plan 😂😂😂
I always knew Clive was a smart guy… but when he referenced Rick and Morty, his IQ went over 9000
I believe the dimple on the cover indicates whether you can tinker with it and not get wet
I don't go diving where i take a dump .. But Ive had some good tat out of a local skip …
They also did a 3-port version that worked pretty much the same way. Frankly, in my opinion they're absolute junk. They run really hot and the switches aren't rated at high enough current. I lost count of the number of times I had to replace the switches.
Simple is fine if it's done well, but sadly these are hopeless in my experience.
