Introduction

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 a programmable model. It includes all the features of the TW205 thermostat plus 7-day programming, four time periods per day, and hold/override options.

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 significantly 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

24 VAC Power – Wiring and Mounting Instructions
This thermostat mounts on a standard 4” x 4” device box with a 2” x 4” horizontal mud ring. See Figure 1.

• To avoid electrical shock or damage to equipment, disconnect all power before installing this thermostat.
• Remove old thermostat (if applicable):
• Remove the front cover of old thermostat. With wires still attached, remove backplate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly.
• Before removing wires from old thermostat, label each wire with the terminal designation from which it was attached.
• Disconnect the wires from the old thermostat one at a time. Do not let wires fall back into the wall.
• Mount TW205/TW206 thermostat backplate:
• Pull wires through the hole of the TW205/TW206 backplate.
• Attach the thermostat backplate to the wall using the enclosed mounting screws. Tighten screws evenly but do not over-tighten.
• Attach wires to the TW205/TW206 thermostat backplate:
• Loosen the screws on the terminal block to allow the wires to be inserted easily.
• Ensure the insulation on each wire is stripped to the proper length, and insert them into the terminal block as shown in the wiring diagram:
• Tighten each terminal block screw until the wires are held firmly in place. Ensure no uninsulated wire is exposed.
• If batteries are to be used for backup, install the batteries into the compartment in the back of the thermostat.
• Attach the thermostat to the backplate and install the optional retaining screw provided with the mounting hardware.

Battery Power Only – Mounting Instructions

• If powered by batteries only, the TW205/TW206 thermostat may be mounted at any location.
• In this case, a device box is not required.
• Mount thermostat backplate to the wall using the enclosed mounting screws. Tighten screws evenly but do not over-tighten.
• Install the batteries into the compartment in the back of the thermostat.
• Attach the thermostat to the backplate and install the optional retaining screw provided with the mounting hardware.

STEP 2 OF 4: THERMOSTAT CONFIGURATION / SERVICE MENU
The installer must configure the thermostat matches the installed heating/cooling system. The Service Menu allows the installer to modify configuration variables that are not normally accessed by the end user. The configuration variables are identified by Menu Number, as listed in the “Service Menu Functions” table.

Accessing the Service Menu

•  Simultaneously press the ▲  ▼ buttons, and hold down for 5 seconds. This takes you to the Service Menu and menu item number “1” will be shown.
•  Push the SYS button to scroll to the Service Menu item number to be configured. The item number that is shown is the one you are selecting.
•  Push the ▲  ▼ buttons to configure the selected menu item.
•  To save your configuration selection and go to the next Menu Number, press SYS.

Saving and Exiting the Service Menu
The Service Menu exits and returns to the user display after 15 seconds of inactivity. Changed values are automatically saved to permanent memory.

STEP 3 OF 4: WIRELESS CONNECTION TO RW205 RECEIVER

• Install the RW205 receiver, following the procedure in the “RW205 Receiver Installation and Operating Instructions” document that came with the RW205.
• After both the TW205/TW206 thermostat and RW205 receiver are installed, turn on power to the equipment.
• NOTE: If you are installing more than one TW205 and RW205 set nearby each other, you must only apply power to one set at a time then perform the connection process. This will prevent unintentional pairing of devices. After the connection process is performed the TW205 thermostat can remain on.
• On the thermostat: Go to Service Menu #43 and select “ON”. After 15 seconds, the display will show “99” and begin counting down to 0. This countdown indicates thermostat is now waiting for a connection request from the RW205 receiver.
• On the RW205 receiver: Depress the CONNECT button using the tip of a paperclip. (The CONNECT button is the small hole on the front of the receiver, immediately under the three device lights. It is not labeled.)
• During the connection process, if any light on the RW205 stops fl ashing, this means a device has been found and successfully paired with. The RW205 will attempt to connect to any available device for 2 minutes or until all available devices have been paired

STEP 4 OF 4: CHECK THERMOSTAT OPERATION

• After thermostat and receiver installation, confi guration, and wireless connection are complete, check thermostat operation:
• Set fan to ON. The blower should begin to operate.
• Set the System Switch to AUTO, or available selection. Using the ▲ button, adjust temperature above the room temperature to cycle heating stage(s) on. Using the ▼ button, adjust temperature below the room temperature to cycle cooling stage(s) on.

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.

• If the reversing valve needs to be energized with a demand for cooling, set Service Menu #41 to “2”.

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.

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.
