i AM TROUBLE SHOOTING A URD 8" AND USING THE WIRING DIAGRAM THAT CAME WITH THE DAMPER. THE HEATING WORKS CORRECTLY EVERY TIME, BUT I CAN'T GET THE COOLING TO MOVE THE DAMPER WHEN THE MANUAL THERMOSTAT IS SWITCHED TO COOLING, EVEN AFTER THE WAITING PERIOD OF 5 MINUTES. IS THERE A FIX TO THIS ISSUE ...
