Mounting Considerations for Wave Wireless System
When selecting mounting locations for Wave Wireless System components, it is important
to consider the number and types of obstructions between components. The Wave
Wireless System will communicate through walls and other obstructions, but they will
reduce the effective operating range of these devices. The effectiveness of the Wave
Wireless System will be greatly reduced if it is mounted within a metal enclosure. The
Wave Wireless System uses frequency-hopping technology to improve its resistance to
wireless interference; however, malfunctioning or improperly used wireless devices may
interfere with the Wave Wireless System. Take note of any other wireless devices in use
near the Wave Wireless System before installation or if communication errors occur.

13. Tighten each terminal block screw until the wires are held firmly in place. Ensure that
no uninsulated wire is exposed.
PART VII: REPLACING OR ADDING ACCESSORIES (OPTIONAL)
Follow either the (A) or (B) connection process below, whichever applies to your installation:
• (A) Connection process for a replacement installation. A brief connection
process must be performed that erases all previously paired devices from the
RW205 memory. Hold the CONNECT button down (see Fig.9) until all the LED lights
begin to flash (about 10 seconds) on the RW205. Wait until all three LEDs stay lit
and begin to flash. Begin the pairing process again at section “PART V: ESTABLISH
A WIRELESS CONNECTION.”
• (B) Connection process for adding a SW205/SW206 device to an existing Wave
Wireless System. If you are only attempting to add a SW205 occupancy sensor
or SW206 door switch to an existing PECO Wave Wireless System, a 5-second
connection process can be performed. Hold down the CONNECT button until the
lights begin to flash. If you are attempting to connect a device and its corresponding
LED does not flash after 5 seconds of holding down the connect button, a 10-second
connection process must be performed. Note: The RW205 will attempt to connect
to any available device for two (2) minutes or until all available devices have been
paired.
PART III: INSTALL BATTERIES IN THE TW205/TW206
Batteries are recommended for the TW205/TW206. Insert two AA batteries (included) in
the back compartment where indicated (see Fig. 8). Assure batteries are inserted properly.
Note: If power is
disconnected from
RW205, remove
batteries from the
TW205/TW206. When
power is restored,
replace the batteries.

PART IV: ADVANCED CONFIGURATION
Perform advanced configuration for TW205/TW206 Thermostat before establishing wireless
pairing (see “Table 1. Advanced Configuration Service Menus” p. 4). Advanced configuration
allows you to customize thermostat settings, such as temperature display, time and day
display (TW206 only), programming commands, and to create setpoints for scheduling
different time periods. Ensure service menu settings correspond to the System Type (see
“RW205 Wiring Examples”).

bottom.
Interpreting the RW205 LED Lights
After devices have been paired (wirelessly) to the RW205, the corresponding LED indicator
lights should remain lit. If communication is broken for more than 5 minutes, in the case of
the TW205/TW206, or 30 minutes for the SW205/206, the LED associated with that device
will shut off. In the event of a communication loss with the TW205/TW206, the RW205 will
shut off all outputs. If the RW205 loses communication with the SW205 or SW206, it will
assume the room is occupied.
Device connection LED
indicator lights
The LED indicator lights on the RW205 may also be used to diagnose communication
errors. Use the following table to interpret the RW205 LEDs.
CONNECT
button
PART V: ESTABLISH A WIRELESS CONNECTION
NOTE: Wireless pairing is time sensitive. Pairing the TW205/TW206 with the RW205
must be completed within two minutes after initiating the pairing process. (If you wait
longer than two minutes, restart the wireless pairing process at Step 1.)
Installation Tips
• Hold the TW205/TW206 Thermostat within 6-10 feet (3 m.) of the RW205
Receiver during pairing.
• Step 3 (below) must be completed within two (2) minutes of completing Step 2,
