I have the same problem, heating unit will not ignite, it trips out, i go into the roof cavity and remove the top of the unit (4 screws) and there is a motherboard, it has a Green light flashing what tells you the type of fault it has, mine has 3 Flashes telling me it a combustion air pressure system failure, ithen push the reset switch and it starts to initiate, a red light comes on and then it ignites and it will work for about 30 minutes to an hour and a half.
Hope this helps

Follow the link above. This is where you find the manuals for these units. I couldn't find the one that is specific for your unit but they do have a way you can contact them and also you might gain enough info from the ones they do have to figure yours out.

SOURCE: TOYO TA-09CHS aircon problem
TOYO mini split air conditioner made in Japan is very very good quality and it can runs for 20 years without any problem. You didn't hire a best ac technician to install your TOYO unit. The tubing connection between indoor unit and outdoor unit is not the right torque and refrigerant leak. Your TOYO unit runs out of refrigerant. You need fix the leak and fully charge the system. You will solve the problem.

I have same problem like yours to my newly installed Fujitsu multi-split system (the first time use since system installed 1 week ago). I rang the electrician who did the installation; he said it must be the units themselves nothing to do with electricity.
Okay, then I rang Fujitsu and their local service agent. They suggested me to switch off C/B for an hour to reset the units. I followed the instruction but the indoor units still did not respond to remote control...
It simply looks like no power supply to indoor units (they are hard-wired to the outdoor unit). So I used a multi-meter to test the power terminals of indoor units (Danger! If you have no idea about this, don't even try! ): it seemed no power supply even C/B is on. I turned to the isolator which next to the outdoor unit. The isolator was making arcing noise when I switched it on and off. The indoor units suddenly turned on for few minutes then died again.
So I figured out the problem is that crooked isolator. I called the unhappy electrician to replace the isolator. End story....
I hope my experience will help you a little bit.
