Chilled water circulates through a pipework distribution system to the heat exchanger (coil) within the fan coil unit. Fans within the unit then draw air over the exchanger containing the cold water cooling the air, which is finally dispersed into the desired space to provide the occupants or building users with comfort cooling.
In the summer, this building uses chilled water and in the winter the building uses hot water which gets distributed to these fan coil units. There is an electrical heater installed for those cold off season days while the chiller is in operation.

New York is nuts! You find the most sh*t I have ever seen. Another great vid, man. Keep 'em coming.

[@JumpermanTech]

It really is. I somehow run into some wild problems and no space to work in all the time lol thank you & thanks for watching! 🔧⚡️

[@AngelHVACR]

You are not wrong bro New York is something else 🤣should see San Francisco man you see some crazy stuff sometimes

[@you166mhz]

yep --- another great vid ....

[@jfrancis98]

You do a great job of talking your way through what you’re doing. Thank you.

[@mxslick50]

The voltage readings on the non running speeds is normal, as the windings act as an auto transformer which will increase the voltage. The current would be the important value, as the current draw on the non active speeds should be close to zero.

[@JumpermanTech]

Thank you for your input! Its very interesting to know. Thanks for watching! 🔧⚡️

[@user-ep3qe1um1h]

Good feedback.

[@GerrDitrih]

Was just about to write a comment on this one, scrolled down and found you wrote it)) I Have diagnosed those units for 10 years now and quiet familiar with this. We have Honeywell Excel 10/12 as a controller for those things (water heated/cooled, depends on time of the year)

Super interesting! Your skill level is remarkable! That's why I like watching you work! 👏🏾👏🏾👏🏾🙌🏾💯

JMT TO THE RESCUE JOB WELL DONE.

[@stevencossaboon3237]

Nice work again Jumper man. That place keeps you busy.

[@fendlygislain2665]

Thought Florida only had pancake units. This is cool to see

[@JumpermanTech]

There are many places with units like these in NYC from fan coil units to heat pumps due to barely any space lol thanks for watching! 🔧⚡️

[@topher8634]

We got em in Georgia too. Some like this with CWS and heating coils or HWS from heat loop.

[@fendlygislain2665]

Oh really that’s cool too, I’m actually moving to Augusta, GA. Is business good up there? Do you know?

[@topher8634]

@@fendlygislain2665 don't know about Augusta, but Atlanta area will keep you busy

[@JumpermanTech]

Facts. Haha thank you my friend! Appreciate you 🙏

[@jrh86]

Great work and great approach to solving what is a demanding and challenging job 💯💯💯👍👍👍and as usual attention to details that others dont bother with...great value..great work.

[@user-ep3qe1um1h]

Great video! Keep up the good work!

[@keovongvilaykeo4799]

Thanks you for sharing your knowledge great work 😊

[@zekenzy6486]

Great Video. Thank you for sharing

[@cliveramsbotty6077]

love a good fancoil. that wiring is criminal

[@jcrackcorn]

Those are induced phantom voltages. Analog meter would read zero as it will pull some amps for needle coil

[@johnwalker890]

Good job Jumper.

[@peterking1134]

The wattage used by the heating coils is correct 8 A times 125 V is approximately 1000 watts so that the coil is working fine

[@thesilentonevictor]

New York keeps the bills paying jmt

Facts. Enjoy the rest of your weekend & thanks for watching! 🔧⚡️

I first hit the "Like" button before I view your videos, that's beacuse I know in advance that I will be viewing "A beautiful thing.'

[@hellhound-si5oz]

Motors act like an auto transformer. The windings are connected internally. That's why you're seeing a higher voltage on different tabs

[@JesseDoesHVAC]

McQuay brings me a lot of work here in Melbourne, Victoria, Australia Most of these units at 20-25 years old now and beginning to show their age

[@chrissmith513]

That wire looks like Spaghetti L o L Happy Easter to everyone 😊😊😊

[@topher8634]

Happy Easter

[@ausseamore8386]

THANKS MAN

[@hidayat2798]

Maintenance Verry good

[@genesismechanical4848]

I never seen a motor do that good to know crazy

[@bigdaddy4975]

The other speeds will have those voltages from the back emf of the motor

[@racfriendstechnical7275]

Nice sir

[@topher8634]

Back EMF will read higher than incoming voltage. Its normal.

[@moholie]

💯

[@JumpermanTech]

[@steveg8337]

What?? No nightmare?? I'm devastated...

[@fendlygislain2665]

I felt that give me a break too 😂😂

[@HEFTYLEFTY303]

When that actuator has power the lever will move back and forth easily

[@coolmyair]

How much was that repair in New York?

[@gekkedirkie]

Nice, another shitshow that pays the bills

[@geoffreyyoung5419]

Jump per groves man

[@HEFTYLEFTY303]

I don't think that actuator was bad bro

Strange voltage stump me every time 😢

[@GODZILLA1521]

Why didn't you show the part with you insulating the pipes.. ?? Anybody could put pipes together with a tool..

[@Hvacrpro123]

The other wires will backfeed voltage when running in any of the speeds.

[@genewheeler6320]

Wow that place is a cluster f

[@Hvacrpro123]

When there’s amperage those other wires will have voltage

[@Hvacrpro123]

Back emf
