Thank you for a good video. The one critique is regarding the lack of detail regarding the wiring of the transformer. This is needed to power whatever thermostat is connected to the mini-split through the thermostat interface. Can you please share some additional details? Is the transformer wired into the mini-split controller board or to the thermostat interface directly?
Is there another universal adaptor(s) you recommend or does it have to be this specific one, this particular one got too expensive? i have Mitsubishi Pead series PEAD series Ceiling Concealed Indoor Air Handling Unit
Hi there . I understand everything about installing this except one thing . S1 and S2 .. what are those ? Can't I just connect my transformer to any 208/230 VAC source or does it specifically have to be from the ic ?
Great video! I have a question about the handheld remote control. When you connect this to the Mitsubishi (I have MSZ-FH25) are you still able to control the basic functions, like vane direction, air purifier, etc with the remote control?
I will answer the question myself now :) Bought the adapter. You can still use the remote to set the vane direction and purifier. You can't set the temperature with the remote (of course).
Great video mate!! I've for the last 4 years for someone to make this type of vlog..I have a question:I have a mitsubishi ac and it has this WIFI module MAC-567IF-E.This module is very very slowly and and outdated.Question is ,can connect my AC MITSUBISHI TO NEST 3RD THERMOSTAT?? CHEERS MATE!
Doesn't wiring up a 2 stage thermostat negate the inverter technology? I thought one of the most efficient parts of those Mitsubishi mini splits was being able to use exactly how much btu's and fan speed you need, versus a 2 stage system that is either 70% or 100% ??
Yes you will dumb down the system. But some people would rather have the ability to control their system remotely or be able to schedule it better. It will still be very energy efficient. Just not as good as it could be.
@@HVACServiceTechnicianTalk gotcha. But there is wifi options for that unit that still let you utilize your inverter capabilities. Jist seems odd to me, inverter technology isn't cheap and if remote management was important, they might as well have saved the money and gone with a single or dual stage system. Interesting that this is a problem to solve. I'm not knocking your solution, I'm perplexed at why this problem exists to solve. Any way, great channel, thanks for sharing everything you do. Have a great day
I have a SEZKD15NA4R1 and I tried installing the PAC-US444CN-1 unit with a Nest but the Nest is saying now voltage in detected. Looks like the Nest is only getting 6V even though the common is detecting 24V through a volt meter. Any thoughts here? Thank you for your video!
Can you control fan speed on your nest thermostat? Cuz I'm having problem controlling fan speed on my nest thermostat on my Mitsubishi ducted systems I connect thru same interface you have
Hi, thanks for the video. May i ask you a question? Nest thermostat goes all the way down to 50F on cooling mode... did you know if the Mitsubishi AC will accept this temperature and keep the compressor running until reaching this temp? I'm trying to find a way to use the mini split as Wine Cellar refrigeration unit, so i need to keep the temperatura around 55F, then i realized that NEST Thermostat can reach my low temperature set point, but i'm not sure if this adapter has the ability to override the AC factory limits for the low temperature. Thank you
I would highly recommend not setting the AC that low. Your asking for alot of issues. I would be looking at refrigeration equipment for that. Not a ductless unit.
Great vid. Will the Nest to work with a Navien boiler set as primary heating source? Will any functionality be lost by not using the Mitsu Pac-44 controller ?
Hey Great Video. I currently have the PEFY-P06-NAMAU-E3 similar to yours in the video and it’s currently wired to a Mitsubishi Smart ME Controller. The thermostat only has A and B wired to it. Would I have to run new cables down to the nest thermostat from the interface ? If so what would I do with the red and black A and B cables? Thanks I appreciate any guidance.
I have AC PEV-P250 Mitsubishi i want convert it to tuya wifi thermostat, can you help me please? the old thermostat is PAR-21MAA i want convert it to thermostat has 5 wires (L,N, and 3 for fan speed) or (24V, and 3 for fan speed)
Good video . Question where did you jump to hook up the transformer to step down to 24 volts . Is it on the S1 and. S2 ? I call Mitsubishi and they did not want to give me any advise
I am trying to use a wall thermostat to shut off the fan on one IDU (MSZ-GL09NA-U1) when the set point has been achieved in that room (I am experiencing temp overshoot due to refrigerant bleed from the branch box). What DIP switch settings will achieve this?
Hi I have been searching this for so long. I have Mitsubishi Multi Head Split system. 5 indoor units. Unit model is MSZ-EF. Will this work with my indoor units? After installing this will I be able to wire each unit to a Nest Thermostat? Can I buy 5 of these adaptors and connect to each of 5 indoor unit? Please advise Thanks
Thanks for the video. We have a Mitsubishi low temperature heat pump. The outside unit is a PUZ-HA36AAT, and the inside unit with a backup electric furnace is a PVA-A36AAT. We installed an Ecobee smart thermostat using the same (or similar) adapter as in your video. It seemed to work okay, although during the heating season, the temperature in the house always seemed different than the set temperature, but only by a degree or so. When we finally got some hot weather we could not get the A/C to comeon. We found out that the system was not reading the temperature at the Ecobee, but was reading it at the temperature sensor in the return duct on the furnace. We could not get the system to read the temperature at the thermostat, so we needed to reinstall the standard Mitsubishi thermostat, which works fine, but is not wifi. Does anyone know about a fix for this or of a Smart wifi thermostat that will work in this application? Any suggestions would be appreciated.
Hi HVAC Service Tech. I have a question. I installed a Mitsubishi ductless mini split heat pump and it works great. However, I notice that it doesn’t stop running even when the set temperature is reached. Do I need a separate thermostat to operate my mini split efficiently ? I assumed that the remote control would act as the thermostat.
@@HVACServiceTechnicianTalk Can you pleaSe make a video of installing it to a ductless mini split ?My unit is Mitsubishi MUZ GE 24NA (outdoor) and MSZ GE 24NA (Indoor).
I have a MrCool with four ductless mini splits to one outside unit. Will this work for something like that? The thermostats that came with the system aren't good at all.
Hi John: What were you able to determine? Your question is my primary conern about this approach as I'm in a colder climate (mountains of NC). 63 is not a low enough setting, particularly when I'm away for long periods of time. It would waste a lot of energy unnecessarily. Thank you.
