INTERPRETING THE RW205 INDICATOR LIGHTS
After devices have been paired (wirelessly) to the RW205 the corresponding Indicator
Lights should remain lit. If communication is broken for more than 5 minutes, in the case of
the TW205/206, or 30 minutes for the SW205/206, the Indicator Light associated with that
device will shut off. In the event of a communication loss with the TW205/206, RW205 will
shut off all outputs. If the RW205 loses communication with the SW205 or SW206, it will
assume the room is occupied.
The indicator lights on the RW205 can also be used to diagnose communication problems.
If the RW205 receives valid messages from a connected device, it will blink once. If the
RW205 receives invalid messages, it will blink twice. An invalid message could be caused
by an excessive amount of obstruction between the RW205 and paired devices, or a large
amount of interference from other wireless devices. If the RW205 indicates invalid messages
frequently, review the "Mounting Considerations" section of this guide for more information.

APPLICATION NOTES

Single-Stage Systems
Systems that use dedicated 1 HEAT and 1 COOL and do not require secondary or staged
outputs:
1. On the RW205 receiver:
• Connect the HEAT OUTPUT to the heating valve.
• Connect the COOL OUTPUT to the cooling valve.
2. On the thermostat:
• Set Service Menu #41 to "0".
(In this case the OA/RV OUTPUT can be used to control and outside air damper.)
Multi-Stage Systems
Systems that use 2 HEAT and 1 COOL:
1. On the RW205 receiver:
• Connect the HEAT OUTPUT to the primary heating input on the system.
• Connect the COOL OUTPUT to the primary cooling input on the system.
• Connect the OA/RV OUTPUT to the secondary heating input on the system.
2. On the thermostat:
• Set Service Menu #41 to "3".
Systems that use 1 HEAT and 2 COOL:
1. On the RW205 receiver:
• Connect the HEAT OUTPUT to the primary heating input on the system.
• Connect the COOL OUTPUT to the primary cooling input on the system.
• Connect the OA/RV OUTPUT to the secondary cooling input on the system.
2. On the thermostat:
• Set Service Menu #41 to "4".
Fig. 7. 2nd Stage Activation
Note: The 2nd stage will be activated when the difference between the setpoint
temperature and zone temperature equals twice the differential. See Figure 7. The "Aux"
icon will be lit on the thermostat display when the 2nd stage is active.
Fan Coil Systems
The RW205 receiver has no pipe sensor, therefore seasonal changeover cannot be
controlled. The Wave Wireless System will operate fan coil systems using the dedicated
HEAT OUTPUT and COOL OUTPUT connected to the associated valve on the fan coil
system. For fan coil systems using 2 HEAT or 2 COOL that are not changed seasonally, refer
to the Multi-Stage Systems section.

Heat Pump Systems
Systems that use a dedicated Compressor input and do not have separate heating and
cooling inputs:
1. On the RW205 receiver:
• Connect the HEAT OUTPUT to the COOL OUTPUT and connect both outputs to the
Compressor input on the system.
• Connect the OA/RV OUTPUT to the reversing valve on the system.
2. On the thermostat:
• If the reversing valve needs to be energized with a demand for heating, set Service
Menu #41 to "1".
• If the reversing valve needs to be energized with a demand for cooling, set Service
Menu #41 to "2".
Systems that use a dedicated Heat and Cool and internally assesses the compressor
demand inside the system:
1. On the RW205 receiver:
• Connect the HEAT OUTPUT to the primary heating input on the system.
• Connect the COOL OUTPUT to the primary cooling input on the system.
• Connect the OA/RV OUTPUT to the secondary heating input on the system.
2. On the thermostat:
• If the reversing valve needs to be energized with a demand for heating, set Service
Menu #41 to "1".
• If the reversing valve needs to be energized with a demand for cooling, set Service
Menu #41 to "2".
Note: When using the PECO Wave Wireless System with systems that use the OA/RV
OUTPUT for heating or cooling, the outside air damper operation function is not available.
Setback
The RW205 receiver's SETBACK INPUT is a low level switchable input that is normally open.
When the switch is closed, the system is in setback mode. In setback mode, the heating and
cooling setback limits are used as temperature control points and fan operation is cycled
with demand at the lowest speed. Pressing any button on the TW205/206 thermostat will
override the setback for 1 hour.
Setback function is enabled via the Service Menu on the thermostat:
• To enable setback function: Set Service Menu #14 to "1".
• To specify the Heating setback limit: Access Service Menu #6 and scroll to desired
temperature.
• To specify the Cooling setback limit: Access Service Menu #7 and scroll to the desired
temperature.
Setback may be triggered automatically or manually. See "System Button Operation" section
of the TW205 operating instructions for more information.

FCC COMPLIANCE

This device complies with part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) this device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.
Warning: Modifi cations not expressly approved by the manufacturer could void the
user's authority to operate the equipment under FCC rules.
NOTE: This equipment has been tested and found to comply with the limits for
a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can
be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
