Thanks for the video. I recently came across this issue. The first thing I noticed as I was walking behind the condensers is that I could audibly hear something bypassing. Upon taking the covers off, I felt that the slave unit wasn't working as hard (in cooling) as the master was. Upon feeling the pipes in and out of the LHS 4 way valve on the slave, I noticed it wasn't working as intended. This video further solidified my diagnosis.
Great video. By any chance dose a PUMMY city multi have a recovery mode? I am having trouble pulling a vacuum just want to make sur my LEV is open at they air handler, thanks.
Hey Madness! I have a question. I just got a building with 250 FC’s and about 30 OC. I have the EA200 centralized controller. I’m getting a 1500 error code. Th15. Any pro Tip of how identify which OC is the unit with the alarm? Note- 30 OC on the Roof.
i am still learning these systems but i think the key is how good the installation was.....i had one where everything was labeled wrong in the AE200 causing all kinds of chaos...installer never wrote down the actual charge anywhere..
Really digging the videos! The oddball issues / more advanced level troubleshooting stuff is killer. Please keep it up!
Thanks for the video.

Address on outdoor unit is set via a round dial inside the electrical panel. So address 51 will be 5 and 1 on the 2 dials

You like working on Mitsubishi or find it troublesome?
I love it! It's built with quality and attention to detail. Unlike a lot of other brands.
Thank you for sharing good luck
Which solenoid was stuck open/closed? Or was it the 4 way valve?
It was one of the 4 ways.
A and b for heating, c for cooling
@@pablochinchilla4372 in the BC? no. Sva and svc for cooling. Svb is heating.
Waiting your direction sir, thank you.
Or try to operate the another unit?
Have you ever seen a 1501 error code?
Do you work on water source mitsubishi?
Yes, I do

Yes exactly, installation is beyond important.
Or turn off both twin unit for letting reach balance condition refrigerant?
If the accumulator is full its just going to sit there especially on a cold day.
@@VrfMadness unfortunately its not happen on a cold day sir.
@@VrfMadness we suck out liquid refrigerant from supply line. But still, compressor is wet and cool.
Sorry i have this trouble right know that little bit serious issue in our AC
Thanks for sharing
Thks!
Our system is same condition that wet in compressor and accumulator. And low pressure 6bar. Low pressure pipe frozen, system will stop.
Daikin stuff?
Unfortunately I don't work on Daikin. Mainly mitsu and some LG (unfortunately, because LG is garbage.)
