Recommended Action(s)
Verify the TRV is receiving power (AC transformer
or DC adapter) and all power cables are in good
condition and are connected.
Refer to:
• "Mounting the Wireless TRV" on page 8
• "Power Input Wiring" on page 9
Configure the System ID. If the LEDs are still
blinking after the System ID has been configured,
contact Customer Support.
Refer to "Programming the Wireless TRV System
ID" on page 5.
Check the Wireless TRV RSSI LEDs (Figure 1 on
page 3). At least three LEDs should be lit, indicating
"good" signal strength.
If fewer than three RSSI LEDs are lit, check to
ensure the antenna connection is secure and that
the antenna is undamaged.
If necessary, remove the source of RF interference
or relocate the Wireless TRV.
