Re: [LHA-misc] Communicating Thermostats (RC80, Aprilaire, etc.)

PIC based inerface for these stats (Statnet and RCS) using RS-485  The 
StatNets are a bit pricy.  But they are a VERY nice unit.  However, 
another really nice setup that is somewhat less expensive is the TR-15 
from RCS (www.resconsys.com)  It uses a split setup with a display unit 
(utilizing the original 4 thremostat wires already there) and a control 
unit that goes near your furnace (or where ever your tstat wires 
terminate)  They also make a new unit, TR-36 with a graphical LCD 
display - I wanted to add support for the cool msg display - but the PIC 
I used didn't have enough RAM for the larger buffer's I'd need.  But the 
code above works well - I've used it in my home for some time.... 
Problem was I never got all the functions added into the HCS firmware 
(HA controller)
