HVAC Service Call: Fan Coil Unit Not Working (FCU HACK JOB REPAIR) FCU Wiring Issues/FCU Not Heating

[@stangaloski4208]

Bro your getting really good with that wiring. I love seeing a younger tech that "gets" it. Your going to be the go to for these places for a long time to come. Can't wait for you to get on some big stuff like intellipak and voyager units.

It looks like the pipe temperature sensors might have been original controls, and the gray control relay was added later on along with the digital thermostat... maybe?

[@ronchambers9762]

Thank You Sir. I really appreciate the confidence you have in yourself to figure out how it is supposed to work and to get it there. There is a lot of knowledge to be gained, by the young guys, to get to listen to your thoughts as you stumble along. That is how we all work, but the young guys don't get to see and hear it very often. Great job

[@mikeblackpoetry5248]

Bro could you do a video of you wiring a current relay to compressor(small compressor) in refrigeration? Not the small black relay but the one with yellow/red/blue wire

[@joemartinez-673]

Strat from scratch ; rewire it all. Someone came behind you and wired wrong. * never trust others .

[@JumpermanTech]

Facts. What a mess. Somebody was definitely messing around in there. Can't trust that wiring at all. Half of my work is fixing other people's mistakes 🤷‍♂️ Thanks for watching! 🔧⚡️

[@CameronKettner]

The second auto changeover switch is probably so that it doesn't open the valve if they select cooling but there is hot water If you wire it so that the output of the thermostat goes to the relay coil, and then the relay outputs go through the changeover switches it will prevent it from turning on the opposite relay.

[@Echoskope]

I agree, I've been drawing out the controls on these FCUs out of curiosity of how the logic works, and this is exactly the case. If the 2nd change over is bypassed and the pipe is hot but the thermostat calls for cooling, the valve will still open thus heating the room.

[@AriefSrimoyo]

Gjob

[@jrh86]

My brain hurts !!

[@JumpermanTech]

Thats how I felt after this call 😂 Thanks for watching🔧⚡️

[@SpachHVAC]

Those relays have caused more hat take offs and head scratching

[@oldmetalguy4577]

Spaghetti!

[@JumpermanTech]

Dry spaghetti with no sauce 😂 Thanks for watching🔧⚡️

[@joemartinez-673]

Wiring change overs is confusing to peeps that do not have experience with them.

[@JumpermanTech]

They really are confusing but not so much when you understand them. Even then, with all the wiring attached to it, it makes it very confusing. Thanks for watching! 🔧⚡️
