CONFIRM OPERATION:
Heater Communication:
Communication between gateway and heaters is evident by rapid flashing of the TX and RX LEDs on the
gateway. If only the TX is flashing (may be as slow as 30 seconds between flashes), that will indicate no
response from the heaters.
Building Automation System Communication:
Using the HTML interface, you can confirm some operations and under USER MESSAGES, confirm there
are no errors messages. At this point, the BAS will need to discover the gateway and implement the points
into its integration.
