I watch this video every. Time.

Should the branch box not be set to 1 higher than the outdoor unit?

[@SeyedRazavi-d7j]

Hi, would it be possible to bypass the BranchBox altogether and directly connect a MultiPosition AHU to an MXZ? For example a 36k AHU to a 48MXZ? If so where can I find the details as how to control the MXZ with BraanchBox out of the picture? Since there is no M-Link communication line from AHU to MXZ wold it be still possible to control the MXZ with AHU? I am trying to get rid of many heads attached to MXZ via BranchBox and go ducted with a larger 36k AHU if possible which would be 36k AHU paired w MXZ4c 48k NAHZ.

Why did you set outdoor unit . To 51. I recently did two branch boxes set first 1 to 0,1 2nd box to 0,4 after using 3 zones in first.. what would out door hyper heat address be and why??

[@georgesizemore7535]

I am confused. You indicate that in addressing the outdoor unit the first digit is set on SWU2 and the second digit on SWU1. The notes on the circuit board clearly indicate the exact opposite. The note nest to SWU1 says first digit and nest to SWU2 as second digit. There were similar instructions for the branch box but I did not see any notes on that circuit board. Please clarify this for me.

I am right there with you this video makes it more confusing.

[@Ray-wr2wr]

it also looks like branch box upside-down or its one of the correct position?

[@felixfernandez442]

Great information

[@gundamrx792]

how do you do this with out a branch box and only a 2 pipe header?

[@krishnaajaayajayaprakas5475]

Thanks sir also i want be know the heavy industry also please

[@Ray-wr2wr]

is this branch box upside down ???

[@jorgeureno7309]

I have and IT signal adapter. PAC-IT51AD-E. Do you have a video for this? And PFFY-P-NEMU-E indoor unit

[@The-LongRoad-Home]

Thanks Brada🤙🏼

[@taylorthuannguyen]

How about SW 1 dip switch 6? Sgould it be on or off?

[@timileyinsheyi926]

Greetings, please explain how to check numbers of indoors on outdoor units

[@johndeerrm]

The indoor units are essentially addressed by enabling them on the sw1 dip switch

[@oliverstreet7704]

See the technical data and service Manual. You can get the MNET address of connected devices from the outdoor unit without going to each indoor unit, but not which address corresponds to which indoor unit. If the indoor unit's remote has a menu with a service mode you can get the indoor unit's address from the remote and possibly some error codes but this varies by the remote model used.

[@ryandouglas9104]

I install a Mitsubishi unit there is no 29 volts going to the outside what may be the cause

[@oliverstreet7704]

If you mean there's no DC signaling on the indoor unit power / signal cable, then if there *is* AC power on the same cable and the indoor unit appears to be powered OR there's no DC power on the low voltage M-NET cable from the outdoor unit to the branch box(es), OR there's no DC power feed to a central controller then; begin by powering everything off and verifying/setting all the DIP switches. Misconfigured switches can prevent anything useful from happening. Then power on and get the operating condition and error codes from the 4 digits of 7-segment LED in the outdoor unit. In normal operating mode the segments are used as individual led indicators, you set switches to get error codes from different devices. You'll need the service and technical data manual for the outdoor unit to understand how to get the codes and continue troubleshooting any indicated errors. You may need the service and technical data manuals for the other system components if the problem is somewhere else, but the only unit with a diagnostic code display is the outdoor unit. The manuals are all available online.

Sir pls tell me how to by pass odu vrf

[@kingpierre4172]

what are the dip setting for puz-a18nka7

[@jashua2089]

Thank you for the education!

[@abhinayaircoolservice1000]

Diagram pls sir

[@LexaPopov]

I’m sorry Jeff. Rotary dial explanation is very broad and confusing.

[@Cursey0]

It’s easy- you’re basically setting the out door unit to address 51. And you’re setting the branch box to address 01. Each port you activate with them be assigned it’s own address. For example, port A is address 01, port B is address 02, port C is address 03 etc. It goes all the way up to 50 if you had that many units and that many branch box ports

[@joelane4670]

@@Cursey0 I have a unit here. I’m using a branch box on ports B and C.. how would I set the parameters on the branch box and the outdoor unit thanks appreciate it
