Hello again,

I have a Rite Temp 7 day programable T stat (~2 years old) that I am switching over to a non programable Honeywell RTH3100C. I live in South Florida and my unit is a 2004 Rheem 3 ton. It has the outdoor evaporator and compressor unit and the indoor air handler. I wish I could tell you guys heat pump/single stage/double stage and all that but I realy dont know what all that means or how to tell. It is a typical air conditoner for south florida in which a/c is used 99.9 % of the time.

Anyway, the Rite Temp had the same wiring labels as my old dial t-stat so when i changed it the wiring was apples to apples. The wires from the unit are connected to the Rite Temp t-stat at:

G
Y
W
RH
RH to RC jumper.

The Honeywell has different wire labels but they give you a conversion chart (in () ) as follows:

E (X, X2)
Aux (W, W1, W2)
Y (Y1, M)
G (F)
O
L (F)
R (V, VR)
B (H)
C (B, X)

From the Rite Temp to the Honeywell, respectively, I can connect my wires as folows:

G to G
Y to Y
W to Aux

My dilema is I have no idea what my RH and RC is converted to the Honeywell setup. The chart does not have these options.

Any help would be appreciated.
Thanks

The new thermostat is for heat pump, and it's not going to work right with your equipment.

You want the heat and cool only.

One I would suggest.
-RTH5100
-RTH110
-RTH1120

I know my store has the RTH110.
