What about the D9 (red) and D10 (Green) leds? Both should be blinking if the UCM  is comunicating with Comfort. If D9 does not flash it means the ID is incorrect. If D10 does not flash it means the Rs485 is not connected to Comfort

Check that the SW7 ID shunts are correctly in place. some  may have become loose  and may be causing the wrong ID to be set
