Anybody has MapleChase 09620 manual available? I'm looking for one to check out what all the wires mean. I want to upgrade it to Honeywell TH8320.

I believe MapleChase is now part of RobertShaw, and I believe this product becomes RobertShaw9620. So, if you have the manual for RobertShaw 9620, it might help too.

The layout of MapleChase 09620 looks like this:

It has three terminals in a horizontal row, whereby two terminals are wired (C in black, R in red, L none).

There are 7 terminals in a vertical row and 5 of them are wired as follows from top to bottom

Y2 (none)
Y1 (yellow)
E (black)
G (green)
W2 (white)
O (red)
B (none)

Thanks very much!

Okay, folks, I found it myself.

Actually, many manuals are available online there.
