Would like a manual for a HAN-1.5/PCB-058V2 air conditioner

It means there is software error in microcontroller. You have to change the PCB inside the ac.

Hi and welcome to FixYa, I am Kelly.

The main Preinted circuit board (PCB) most likely has had a failure of the small PCB transformer. This is the most susceptable component (PCB transformer) in the Air Conditioner. Within the last 60 days I have personally experienced the exact same symtom. I replaced the PCB transformer and 1 diode on the main PCB of the air-conditioner and my AC unit is working fine. Unless you can find a source for the transformer your only option is to replace the PCB (Board).

Finding the exact transrformer for the PCB can take a very long time. It iwll look similar to this one: http://www.machsources.com/productimages/9913/pcb-mounting-transformer.jpg

If you have home owners insurance ALL STATE and State Farm often cover this type of damage. It is worth the time to find out if you are a home owner.

Thanks for choosing FixYa,
Kelly

P05-Current value sent from MDC on outdoor unit control PCB is low. No AC power input for 3
minutes or longer: pre-trip - 5

Solution:
1. Check R/S/T power.
2. Check inverter control PCB.
3. Check outdoor unit control
PCB.

Thanks.

Try with this method which happened last week experience. Replace new batteries. And also remove dc wire to indoor unit display sensor. And after 3 minutes fix it again. And now start with remote. Mostly it will. If not, you have to replace receiving sensor in PCB or replace complete PCB. Please write back about the result. Thanks.

E-1 Room sensor and A1 Indoor PCB fault. Please you replace first,indoor sensor and reset.Sometimes indoor pcb shows fault code due to sensor short. After replacing sensor it will show only A! or sometimes no error. If it shows A1, you have to repair/replace PCB. Helpful?

It's malfunction of PCB. switch off and reset it. And then chcek manually. May be defective remote commands for malfunction. Check with another remote.

E-1 Indoor unit return air sensor fault. Disconnect sensor from PCB and measure resistance. 8 kOhm at 30C and 13 kOhm at 20C if not replace sensor. Helpful?
