Re: YORK A/C Checksum unknown
Thanks for the insights. It helped me focus. I actually have a Senville AURA heat pump and it is close but slightly different. It's message is 48 bits, repeated where the repeated message has its bits reversed. 40 bits are the data, 8 bits are the checksum. The checksum is first byte by byte reverse...
