Modbus TCP HVAC Gateway

The example assumes that the product type and indoor unit address are both 0.
You can calculate coil/register address using this formula (point number is from the table that you have provided where addressing starts from 1):
address = TYPE * 4096 + UNIT_ADDR * 16 + POINT - 1
