Follow these steps to troubleshoot your Transformer
TRANSFORMER INPUT/OUTPUT
1. Connect transformer to 120V source. Ensure the RED POWER LED inside the transformer near
output terminal is lit.
2. With low voltage fixtures disconnected, test transformer output by switching 3-position switch
(see picture) to ON. Green output LED(s) should light. Return switch to APP for
Bluetooth connected operation.
IF THE ABOVE STEPS TEST OK, IN MOST CASES, YOUR TRANSFORMER IS WORKING PROPERLY.
IF PROBLEMS PERSIST, FOLLOW THE STEPS BELOW.
BLUETOOTH CONTROL AND SETTINGS
3. Ensure 3-position switch is in the APP position. When connected through the app, ensure transformer’s
internal green LED(s) light when control “ON” is selected for either circuit.
4. Try the app with a different smartphone/tablet. If you are having issues with Android, try an iOS
device, and visa-versa, to see if you get better results. We want to isolate transformer
issues by eliminating the connecting device.
5. Make sure your JSST app and device operating system software is the latest version from the App Store/
Google Play Store. When in doubt, you can always delete and re-install the app. When using iOS,
go to SETTINGS, iTunes & App Stores and always enable “Updates” under the AUTOMATIC
DOWNLOADS section. Android devices should update automatically – no action necessary.
6. Try unplugging the transformer, waiting a few seconds, and plugging it back in.
7. Power your smartphone/tablet completely off and back on again (reboot). This can fix certain Bluetooth-
related and app settings issues.
8. Try the Erase Existing Programming button at the bottom of the settings screen in the app.
Important Notes and Latest JSST Control updates:
MEMORY
- All changes made to your JSST transformer settings, when saved, become permanent (non-volatile) part of
memory inside the transformer. In the event of a power outage, settings do not get erased. Changes to settings are only
possible with connection via the app.
AUTO PLAY
- The Auto Play demo in the app only works on one side at a time, not both. When on the overview screen
and either running through the schedule with the Auto Play button or by scrubbing through manually, the Brightness bar
applies only to the side that is selected up at the top. The same applies to the lamps connected to the transformer: only
the lamps connected to the side that is selected at the top of the screen will update their brightness as the sliders move
around. The other side that is NOT selected will remain frozen where ever it was when it became un-selected. You can
switch back and forth between the two sides while auto play is running.
CLOCK ACCURACY
- The “Timezone” section under settings in the app displays your current timezone. This allows
you to verify that location services are turned on for your device and that your location is correct. If your device asks,
always answer “allow” to the question “use current location?”. Location data is required for your transfomer to calculate
sunrise and sunset times. The local time used by the transformer firmware will always be correct either until there is an
unlikely drift in accuracy over time or there is a 120v power outage. In the event of a power outage, the transformer’s
RTC (real-time clock) time will be maintained via transformer’s internal battery. When power is restored, vPRO time will
be corrected by RTC time. Transformer firmware is set to synchronize with the external RTC once per week, or, when
connected to the app, the time will be updated automatically from the connected device.
