HVRF Testing

Checking correct setting of branch ports. To ensure that each indoor unit has the correct branch port setting, approximately half the indoor units attached to each master HBC should be set to test cooling and the other half to test heating. Then change one unit’s mode in the opposite mode previously and note if the correct unit changes in temperature. If, however, another units temperature does change and its mode hasn’t then it is likely that the branch port setting (SW14) is incorrect. It is recommended to test all branch ports before making any changes to the SW14 branch port setting in the indoor unit.
