I have a Robertshaw 9520 2 heat/2cool nonprogrammable thermostat. I would like to simply purchase a "programmable" thermostat and hook the wires up as they are now. I wrote Robertshaw to ask what the upgrade would be to a programmable thermostat to replace the 9520 and I guess they did not have time to respond. Anyway I was wondering if anyone could recommend a replacement thermostat for the one described above. My wiring is as follows:

Terminal/Wire Color
------------------------
C/brown
L/orange
R/red
Y2/no wire
Y1/yellow
E/no wire
G/green
W2/white
O/blue
B/no wire

Thank you for your time and I appreciate any help I can get.

Honeywell makes a nice programmable t-stat called honeywell 6000. They come in 1 heat and 2 heat models just make sure you get the correct one for your 2 heat application.
