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.

SYSTEM BUTTON OPERATION (cont.)
MENU DESCRIPTION
SETBACK Setback mode is an energy saving feature that minimizes the heating and
cooling when the room is not occupied. Setback mode overrides the
programmed time and temperature settings by telling the thermostat to
instead use the setback setpoint for heating and cooling. The setback
setpoint temperatures are factory default or installer-selected during
installation. During setback mode, when a demand for heating or cooling
exists, the fan will run at the lowest speed.
• Automatic setback mode: If your thermostat is connected to an occupancy
sensor or door switch, setback mode is automatically turned on and off by
the sensor or door switch.
• Manual setback mode: Select SETBACK in the SYSTEM menu. Setback
temperature settings will remain in effect until you manually turn off
setback mode. Selecting HEAT, COOL, or AUTO in the SYSTEM menu
will turn off setback and resume your programmed time and temperature
settings.
Note: SETBACK appears on your menu only if this feature was enabled by
your thermostat’s installer.
