Install the T2500 Thermostat backplate

The T2500 Thermostat is intended for indoor installation only. It should be mounted on an inner wall, in a location with freely circulating air, where it will be responsive to changes in room temperature. Avoid mounting the thermostat near heat-generating appliances (i.e., TV, heater, refrigerator), or in direct sunlight. This instruction assumes that the installer will use pre-existing wires found at the location of the previously-installed thermostat

Power Options The T2500 will operate on 24 VAC power and/or two AA alkaline batteries. Where possible, the thermostat should be operated on 24 VAC power with battery backup.

Remove the old thermostat

• Turn off all power for heating/cooling system (or for fuse/circuit breaker panel) before installing thermostat to avoid electrical shock or damage to equipment.
• Remove the cover of old thermostat (see Fig.6).
• Label each wire with the terminal to which it was attached before removing wires from the old thermostat (see Fig.7).
• Disconnect wires. Do not let wires fall back into the wall.
• Remove backplate from the wall after all wires are labeled. If old thermostat has a wall mounting plate, remove both of these as an assembly
• Use a level to mark the backplate mounting position.
• Mark positions of the screw holes (two at minimum) with a pencil.
• Drill holes at pencil-marked locations (3/16” for drywall, 7/32” for plaster).
• Insert the wall anchors in the holes. Use a hammer to gently tap anchors into holes.
•  Mount the T2500 Thermostat backplate on the wall. Assure that all loose wires come through the center opening of the backplate (see Fig. 8).

Attach wires to the T2500 Thermostat backplate

• Using a small flathead screwdriver, loosen the screws on the terminal block, located on the backplate, to allow the wires to be inserted easily.
• Strip the insulation of each wire at a proper length (about 1/4” or .64cm).
• Insert the appropriate wires into the terminal block as shown in the wiring diagram below (see Fig. 9 ).
• Connect 24VAC 1 to terminal 1
• Connect 24VAC 2 to terminal 2
• Tighten each terminal block screw until the wires are held firmly in place. Ensure that no uninsulated wire is exposed.

Install batteries in the T2500

Batteries are recommended for the T2500 Thermostat. Insert two AA batteries (included) in the T2500 Thermostat back compartment where indicated (see Fig. 10). Assure batteries are inserted properly

Perform advanced configuration of the T2500 before pairing.
Perform advanced configuration for thermostat before performing wireless pairing. (See “Advanced Configuration” section). Advanced configuration allows you to customize thermostat settings, such as temperature display, time and day display, programming commands, and to create setpoints for scheduling different time periods. For more information on using the thermostat’s buttons and features, refer to the “WavePRO Wireless Programmable T2500 Thermostat & R2500 Receiver Operating Manual.”

Establish a wireless connection
Perform wireless pairing after the R2500 is installed and the advanced configuration is complete. For best results, perform wireless pairing before the T2500 Thermostat is attached to the backplate

• Turn on power to both the T2500 and R2500. Note: DO NOT attempt to pair more than one WavePRO Wireless System simultaneously.
• Using a paperclip on the R2500 Receiver, push and hold the CONNECT button until all three LED lights flash for about 10 seconds (see Fig.11).
• If only two LEDs flash, continue pressing CONNECT button until all three LEDs flash.
• Push simultaneously ▲ and ▼ buttons on T2500 until 1 appears in Display.
• Push the SYSTEM button continuously until Service Menu 43 appears.
• Pause at Service Menu 43. The display will change to 0.
• Push ▲ the button to change the 0 to 1 within Service Menu Function 43.
• T2500 Display will begin the countdown from 99 and stop before 0. (Countdown indicates that the pairing process has begun).
• Wait for the Service Indicator on the T2500 to begin flashing (indicating the R2500 was found but pairing process is not yet complete).
• T2500 Display will show the room temperature.
• Wait for up to 10 minutes to allow completion of pairing process.
• Do not press buttons during this process. Wireless pairing is successful only when you see the following:
• R2500 “Thermostat” LED is continuously lit.
• T2500 Service Indicator disappears from Display

Verify wireless pairing

•  Press the FAN button on T2500 Thermostat.
•  Press the FAN button continuously until ON is flashing.
•  Allow timeout. The flashing menu option (ON) is automatically selected.
• Note: The fan blower should begin to operate (there may be a delay).
•  Press the FAN button until AUTO begins flashing so it is automatically selected.
• Note: FAN has now been reset to AUTO.
•  Allow the device to time out. Wireless verification is complete

Interpreting the R2500 Indicator LEDs
LED indicator lights on the R2500 may also be used to diagnose communication errors. Use the following table to interpret the R2500 LEDs.

If R2500 LED… Interpretation

• Blinks once R2500 is receiving valid messages from another device.
• Blinks twice R2500 is receiving invalid messages from another device
• Blinks intermittently R2500 is receiving invalid messages that may be caused by an excessive amount of obstruction between the R2500 and other wireless paired devices; or from excessive interference from other wireless devices. Note: If the R2500 LEDs indicate invalid messages frequently, review for help the following sections: “Install R2500 Receiver” or “Frequently asked questions & troubleshooting.”

If replacing either the T2500 or the R2500, follow these instructions:
A brief connection process must be performed that erases all previously paired devices from the R2500 memory. Hold the CONNECT button down until all the LED lights begin to flash (about 10 seconds). Wait until all three LEDs stay lit for one (1) second and begin to flash. Begin the pairing process again at section “5. Establish a wireless connection

Mount the T2500 onto the backplate

• Attach the thermostat by sliding the mounting tabs (on its reverse side) down onto the hinge pockets on the backplate (see Fig. 12-13). Make sure that thermostat’s pins on reverse fit securely into the terminal block on the backplate.
• Install retaining screw provided with the mounting hardware (see Fig. 12).
• Note: Inserting the retaining screw is recommended to assure thermostat is securely attached to the wall
