Aquastar Ii Valve Malfunction. Downloaded Manual. Completed Diagnosis.

Accomplished all manual directions for not heating. The valve always returns to pool loop when controller is switched on in all auto, manual off and test even when manually positioned to solar loop. Will not stay there. Even placed solar sensor in hot water. Anyone know what VAC values should be for NC C and NO in the controller? Thanks,
