THE PECO WAVE WIRELESS SYSTEM
The PECO Wave Wireless System is comprised of the TW206 wireless thermostat paired with a
RW205 receiver. Optional accessories to the system are the SW205 wireless occupancy sensor
and SW206 wireless door switch. The Wave Wireless System is intended for use primarily in
2- or 4-Pipe Fan Coil Units, PTAC, PTHP, and on/off control applications.
The TW206 thermostat is a wireless programmable thermostat that may be powered by battery,
24 VAC, or both. It can be set for 7-day, 5/2-day, 5/1/1-day, or 1-day programmable operation,
with 4 time periods per day. The thermostat also features separate heating and cooling
setpoints, auto changeover, fan control functions, and wireless communication with the RW205
receiver. The RW205 receiver is wired to the HVAC equipment and controls all outputs. The
optional SW205 occupancy sensor and SW206 door switch also communicate wirelessly with
the RW205 receiver to signal occupancy status.
Any changes or modifications not expressly approved by the party responsible for 
compliance could void the user's authority to operate this equipment.

SAVING CHANGES
As you navigate your thermostat, be aware of the thermostat’s save and exit protocol:
• The thermostat automatically saves all the changes you make, as you make them.
• When you are in the SYSTEM or FAN menus:
– If you push a button that is not applicable to the current menu, all changes are saved and
the thermostat goes to the menu associated with the button that was pushed.
– If the thermostat is idle for ve seconds, the thermostat times out, saves all changes, and
returns to the thermostat’s default display.
• When you are in the PROGRAM menu:
– If you push a button that is not applicable to the current menu, nothing happens (your
programming is not interrupted).
– If the thermostat is idle for fteen seconds, the thermostat times out, saves all changes,
and returns to the thermostat’s default display.
– When you have nished the last step of programming a setting, pressing PROGRAM
saves your setting and returns the thermostat to the default display.
