Thank you
Thank you very much from informations khalid du Maroc Casablanca
Good jab
Amazing. Do you have a video for E5?
Which air conditioner?
❣ thank you!
Please explain the communication circuit by drawing circuit pls and also tell how to check the voltages on the optocoupler
I have random E1 errors. Sometimes I turn on the heat and get 10 minutes to an E1 message and it turns off. However for the past 5 days it's been running normal.
Great video like always ❤
6.36 can we check this voltage using multimeter?
Yes you can!
@@forevertechenglish great thanks 👍
Surge protection should installed on the incoming power supply of all new inverter HVAC equipment. For some reason, manufacturers don’t want to spend the money to protect sensitive electronics.
I installed a whole house surge protector in my main breaker panel after losing my furnace blower motor to a huge power surge.
Super 😊
I have error code E1 ac NAME ALTECH i dont know what is the problem...?thanks for any help

How did you power indoor unit without connecting outdoor unit? Indoor unit is powered by outdoor unit.
Indoor unit can be powered on without the outdoor unit attached to it.

Hi sir, thank you for your video, I have a question and would appreciate it if you could please answer, I have a Airlux split system and the outdoor unit is not working, can I replace it with dikin, will it communicate with the airlux indoor unit
No it will not communicate with an outdoor from different brand. Unless and untill the circuit boards used in the outdoor units are the same.
Della 12000 btu 110 volts mini split
Okay can you send me picture of the outdoor and indoor control board, I can help you out what the error code e5 means on this unit.Della
Ok i found it, E5 is the communication error in Della mini split, well could be a problem with the wire or the control board on the outdoor unit.
I can solve aprox all the problems of the pcb
