I have a 1996 Maple Chase Thermostat and would like to put in the new Robert Shaw Thermostat. The problem is the new RS Thermostat does not use the Brown, Black & Red wires that were connected to the Maple Chase.
The maple Case is wired up as follows:
Brown - C
Black - L
Red - R
Skip - y2
Yellow - y1
Skip - e
Green -G
White - W2
Orange - O
Blue - B
I don't have the C,L & R on the new Robert Shaw Thermostat. How do wire this up. Thanks George

No R on the new stat? What is the model number of the new stat?

What type of heating system do you have and which Shaw stat did you get?

I've never seen a stat without an 'R' terminal.

The ones I've installed had two red frequently jumpered

The new unit is a Robert Shaw 9620 and I'm running a Rheem Heat pump The old unit is a Maple Chase 9620. I'm returning the thermostat the unit is missing the screw lugs where the R, L, & C wires connect. Other than that it should have been a exact wire hook up as I stated in the first post. I bought the unit from ZORO. Thanks George
