Thank you for choosing the PECO®Wave Wireless®System.
The PECO Wave Wireless Systemis comprised of a wireless thermostat transmitter and a
receiver. PECO offers two wireless thermostats: the non-programmable TW205 Thermostat,
and the programmable TW206 Thermostat. Both operate with the same wireless RW205
Receiver. This operating manual contains important information on operating the TW205 and
TW206 Thermostats and on the RW205 Receiver.
The TW205/TW206 are designed for use primarily in 2- or 4-Pipe Fan Coil Units, PTAC,
PTHP, and heat pump applications. The TW205/TW206 support 1-HEAT/1-COOL, 1-HEAT/
2-COOL, 2-HEAT/1-COOL, and three fan speeds. The TW205/TW206 may be powered by
batteries, 24 VAC, or both (recommended). The TW206 can be configured for 7-day individual,
5/2-day, 5/1/1-day, or 7-day identical programmable operation, with four time periods per day.
The TW205/TW206 feature an attractive blue digital display and support auto changeover,
remote temperature probes, outdoor air damper/reversing valves, wireless occupancy sensors
(SW205), and door switches (SW206).
The RW205 Receiver is wired to the HVAC equipment and controls all outputs.

!CAUTION!
•READ INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO OPERATE THIS THERMOSTAT AND
RECEIVER.
• Contact a qualified service person if at any time your system does not operate properly.
• Use care to avoid static discharge to the thermostat and receiver.
• Failure to observe safety information and comply with instructions could result in PERSONAL INJURY,
DEATH AND/OR PROPERTY DAMAGE.
• To avoid electrical shock or damage to equipment, disconnect power before installing or servicing and use
only wiring with insulation rated for full thermostat operating voltage.
• To avoid potential fire and/or explosion, do not use in potentially flammable or explosive atmospheres.
• This product, when installed, will be part of an engineered system whose specifications and performance
characteristics are not designed or controlled by PECO. You must review your application and national
and local codes to assure that your installation will be functional and safe.
• Retain these instructions for future reference.
IMPORTANT NOTE: This thermostat was shipped with factory default settings. Your thermostat’s installer
may have configured the thermostat differently from the factory default settings, and may have modified
or disabled certain features. Contact the installer or a service technician if you have questions about the
thermostat’s configuration.

System Button
The SYS (system) button is used to control the operating mode of the TW205/TW206.
Press the SYS button once to show the menu options, as described below. Continue
pressing SYS button to scroll through menu options. As you scroll, the menu option
being accessed (operating mode) will flash. To select that option, allow the display to
automatically time out. The TW205/TW206 saves the “flashing” option and switches the
thermostat to the selected operating mode. The SYS modes are:
HEAT – Indicates the system is in heating mode.
COOL – Indicates the system is in cooling mode.
AUTO – Indicates the system will automatically changeover between heating
and cooling modes as the room temperature varies.
OFF – Disables thermostat outputs.
SETBACK –Indicates the heating or cooling system is operating in manual setback
mode. (To appear, SETBACK must be selected in “Advanced Configuration.” See the
“PECO Wave Wireless System TW205/TW206 &RW205 Installation Guide”).
NOTE: SETBACK must be selected in the Service Menu in order to appear in
the SYS mode (see “Advanced Configuration” in the “Wave Wireless System
TW205-TW206 & RW205 Thermostat and Receiver Installation Instructions”). The
SYS button is also used to scroll through the Service Menu in advanced configuration.
