RE: Re: Heatmiser - advice please?!
Hi Bruce/All
Sorry to hijack your thread I have been looking at this thread and now
attempting to interface to the Heatmiser stats, I have a rs485
configurable
port on my controller, that handles 4 wire and 2 wire , ( so I have some
variables )
Could you let me known what the y and b connect to + and - ?,
Also if I get past the first hurdle , looking at the codes ...
If I send set sat at address 01 power on, ( with the value for on at FF )
dose that mean the check sum is more than one byte
Hope this make sense

Ah Sunday morning brain failure - I see now you are after the PRT and
not the PRT-N. I thought it was only the "-N" devices that had
the Y
and B wires for the RS 485 interface on them? I could well be wrong
though.
Cheers, Bruce.
