RF PAIRING
The RF icon in the top right corner of the LCD shows the RF
connection state between transmitter and receiver. (Figure
513)
• BLANK: No receiver paired
• SOLID: Transmitter and receiver connected
• FLASHING: Receiver paired but disconnected
• When you rst power up a transmitter and receiver they
will be in pairing mode for 10 minutes. If you need to start the
pairing process after this timeframe, follow these steps:
1. At the Receiver, use a small at head screw driver to open
the grey front cover. Hold down the RF Pairing button for
5 seconds until the Blue RF indicator LED starts to ash.
(Figure 514)
2. At the Transmitter put thermostat in OFF mode and hold
FAN and DOWN buttons for 10 seconds. (Figure 515)
3. When the screen says ‘YES’ press the MODE button to start
scanning process.
4. After scanning, the display will show the ID and RSSI signal
strength of any receivers it has found. Match the receiver ID
with the label found inside the receiver housing near to the
RF Pairing button. If more than 1 receiver has been found,
use the UP and DOWN buttons to select the desired Receiver.
Press MODE to conrm selection or press FAN to go back.
5. If needed, steps 3 & 4 may be repeated to check signal
strength in different locations. A signal strength between 40
and -70 is required.
6. If the thermostat is experiencing connectivity issues move
the transmitter closer to the PTAC, re-orientate the receiver
within the PTAC, or place the receiver outside of the PTAC.
