Hello, I am changing a Baystat 239 to a LUX TX500 (LUX 500) and would appreciate anyone's help.

The Baystat is currently wired as:

X2 - Black
O - Orange
G - taped off
Y - Yellow
T - Tan
R - Red

F - Vacant
B - Blue

The LUX 500 has the following available and is referenced per the manual:

G - Fan Relay
Y - Cooling Compressor
W - Heating Control
RH - Heating Transformer
RC - Cooling Transformer

Link for LUX 500 PDF manual:

What would the final configuration look like for the LUX 500?

G -
Y -
W -
RH -
RC -

Thank you greatly!

Your Lux stat will not work for your multistage heat pump.
I recommend the Honeywell RTH7400 or RTH7500 from Home Depot.
The RTH6300 wil not work for your heat pump.

Houston, many thanks for the advice! I will take a look at those two options and go from there...

I assume the wiring is straight forward for these two.?.?

C = blue (common)
G = green (fan)
Y = yellow (compressor)
O/B = orange (reversing valve)
Rc & R = red (24VAC)
Aux = white (heat strip)
E = black (heat strip)
Tape off tan (outdoor stat)

Set option 170 to 7 (multistage heatpump)
Option 190 to 0 (O/B terminal is O)

I see you posted that G was taped off, perhaps you are mistaken?

An example...

Houston, again you are amazing me with details...

will get back to you on G being taped off when I get back to the house in a few. I tried to be very accurate in my mapping out the 239 but I will look again.

thank you...
