Hi All,
I'm having trouble connecting to a RC-80 via serial connection. I believe I have the cabling correct. I've searched the boards and with google and all I can figure is that I need to set something on the thermostat to enable serial communications. According to the features of the thermostat:
"4 communications modes, selectable during installation: 2 serial modes for connection to home automation systems, building management systems and personal computers, and 2 voltage signal modes for connection to time clocks, remote setback switches and many burglar alarm panels"
and from the installation manual:
"Your thermostat can be connected to an automation system or
personal computer. With network software, the remote system can
send commands to the thermostat to change mode, cool setting, heat
setting, status of fan and hold, and other items.
"REMOTE" will be displayed when a command is sent from the
automation system or personal computer. You can use the arrow
keys (<->) on the thermostat to change the temperature settings.
When the temperature settings are changed at the thermostat,
"REMOTE" will no longer be displayed. Press the Hold key to
prevent thermostat programs or the remote system from changing
temperature settings. "HOLD" will be displayed at the thermostat."
However, I can't figure what needs to do to toggle between these modes. I think there is an installation PDF that is not available to the public.
Anyone have any tips for me?
Thanks,
Jason
