IMPORTANT
A maximum of five wireless repeaters can be
added per RTU
Repeater – Signal Strength Alert
Indication
Once the wireless repeater is added successfully,
it will communicate with the rooftop unit.
The signal (RSSI) LED will turn on if it cannot
reach the RTU.
NOTE:
The signal strength LED is always en-
abled and cannot be disabled.
Repeater – Placement and Confirming
Location (Test)
The wireless repeater has no test functionality to
determine the repeater is within acceptable range
of the RTU. To test a desired location for signal
strength, use the following procedure:
1. Take a battery powered wireless sensor that is
already connected to the BLE network to the
desired location.
2.
Hold the beaconing button for five seconds
and release.
3. Observe the status of the signal strength LED
(see Table 1. Sensor LED Descriptions on
page 17).
NOTE:
Wait 5 to 20 seconds for the test to com-
pete and observe the signal strength
LED.
