CAUTION
!
• Use copper wire only, insulate or wire nut all unused leads.
• Care should be used to avoid electrostatic discharge to the thermostat.
THE PECO WAVE WIRELESS SYSTEM™
The PECO Wave Wireless System is comprised of the TW205 or 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 TW205 thermostat is a nonprogrammable digital thermostat that may be powered by
battery, 24 VAC, or both. It 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.
The TW206 thermostat is the programmable model. It includes all the features of the TW205
thermostat plus 7-day programming, four time periods per day, and hold/override options.
APPLICATIONS AND FEATURES
The PECO Wave Wireless System is intended for use in PTAC, PTHP, and On/Off control
applications.
• System mode selections: Off-Heat-Cool-Auto-Setback
• Stages: 1 Heat/1 Cool, 2 Heat/1 Cool, 1 Heat/2 Cool
• 6 outputs (RW205): 1 Heat, 1 Cool, Up to 3 Fan, Outside Air Damper / Reversing Valve
• Fan control: 1-3 Speeds, Cycling (Auto) or Continuous (On)
• Permanent memory: The thermostat does not need batteries to store user-confi gured
settings in memory. Nonvolatile memory (EEPROM) saves temperature setpoints, fan, and
system settings for unlimited time. In the event of power loss, time settings are kept for at
least one year (TW206).
• Connections for Remote Temperature Probe and Setback (RW205)

!
•
READ THESE INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO
INSTALL, OPERATE OR SERVICE THIS THERMOSTAT.
•
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.
•
Before installing this control, the Voltage Selection Switch must be placed in the
correct position. See instructions.
•
To avoid potential fi re and/or explosion do not use in potentially fl ammable or
explosive atmospheres.
•
Retain these instructions for future reference. This product, when installed,
will be part of an engineered system whose specifi cations 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.

WAVE WIRELESS SYSTEM MOUNTING CONSIDERATIONS
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. Mounting any device within a metal enclosure
may signifi cantly reduce its communicating range. 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 frequently.
INSTALLATION
STEP 1 OF 4: THERMOSTAT WIRING AND MOUNTING
Mounting Location
The thermostat should be used indoors only. It should be mounted on an inner wall in
a location with freely circulating air, and where it will be responsive to changes in room
temperature. Avoid mounting near heat generating appliances (i.e. TV, heater, refrigerator),
or in direct sunlight.
Power Options
The thermostat will operate on either 24 VAC power or two AA alkaline batteries. Follow
instructions for chosen power option in the appropriate section below. If desired, thermostat
may operate on 24 VAC power with battery backup (follow the 24 VAC Power instructions).
