I changed the number of bits to 16 in the controller but still I get:
Checksum error in rtu mode: '\x01ú' instead of 'éú' .
The response is: '\x01\x03\x9cA\x00\x01ú' (plain response: '\x01\x03\x9cA\x00\x01ú')
many thanks in advance

What bits in which controller?
Minimalmodbus do it right, so your instrument is broken. CRC should be 0xFA 0xE9 which is exactly what minimalmodbus complains.
