Table 1 provides LED status indicator information for troubleshooting the controllers.
Note: If you experience short circuits in the 24 VAC power supply causing protective devices such as breakers or fuses to trip, make sure that the power connections on the VMA are not reversed. The most common cause of this problem is when the 24 VAC power supply on the VMA is reversed but not reversed on a connected secondary device. Improper wiring of this power terminal may cause a short circuit across the 24 VAC power supply on -1 models.
