Hello,

If heat only you will want the red wire on R and the yellow wire on W. Is this how you have wired?

No yellow wire is in Y

The issue is the color wires you have coming out of wall are not color coded correctly.

Pretend the yellow is a white...and attach W.

R and W are the 2 wire terminals needed for heat. Just move yellow to W and let me know result.
