    display--heating err

    I went to a call this weekend with a r2105 displaying HEATING ERR. Checked the man/reset high limit-ok. Turn control off/on.
    Hot water is calling, but no power out of the burner terminals. I have continuity across internal fuse, but no power to or from terminals. The display shows the flame signal,and the call for heat has been acknowledged. When I put it to manual, burner fires. Any ideas, I was thinking bad module.
