Sadashi,
As I understand, you use the original controller of the inverter airco. You have placed the temperature sensor from the indoor coil on yhe brazed plate heat exchanger, and the air temp sensor on the water return.
But what did you do with the fan of the indoor unit? Did the original controller not complaint when you run the ac without an indoor fan connected?
Love to hear more details on this setup,
Murdock
