I need to replace a bunch of Mammoth T-stats with some other manufacturer but can't seem to find one with a "fault light".

My Mammoth stats wiring designation:

C 24 Volt Common
X Fault LED
G Fan
Y1 Compressor
R 24 Volt Power
O Reversing Valve

P 2hr Override
N Night Setback

P and N I can do without as we don't use either feature.

The Water Furnace TA32W02 shows to have a fault light. Will it work and be a good replacement to the ancient Mammoth T-stat??

Thanks all for any help you might provide me!!!
