Status Indication LEDs
The VRF Smart Gateway communicates status using
LEDs to indicate the following functional states:
•
power
•
fault
•
H-Link bus communication
•
Ethernet communication
•
Wi-Fi strength
See the following table for a comprehensive list of VRF
Smart Gateway LED functional information.

Wi-Fi strength is
indicated by the
number of LEDs that
are lit, with one lit LED
indicating weak
wireless signal
strength (between 1%
and 49%) and three lit
LEDs indicating
excellent wireless
signal strength (at
least 75%).

LED Test Sequence at Startup
During startup, the VRF Smart Gateway automatically
initiates a self-test to verify proper operation of the unit.
Immediately after connecting supply power, the following
LED lighting sequence occurs:
1. The Power LED turns on, and stays lit.
2. The Fault LED indicator flashes for approximately 40
seconds, then turns off when the VRF Smart Gateway
is fully functional.
3. The Wi-Fi LEDs light up in succession (scanning),
indicating that the VRF Smart Gateway is waiting for
a device to join its Wi-Fi network.
Repair Information
If the VRF Smart Gateway fails to operate within its
specifications, replace it. The VRF Smart Gateway is not
a serviceable product; however, it does support software
updates to enable feature enhancements. For a
replacement unit, software updates, or accessories,
contact the nearest Johnson Controls representative.
Do not open the VRF Smart Gateway housing. The VRF
Smart Gateway has no user-serviceable parts inside.
