    What is PROsync?

    The PROsync™ Wireless System is an all-new wireless solution that allows you to maximize comfort in any room in your house. When different parts of your home are conditioned by a single HVAC system, it can cause issues. Even though one part of the house may be just right, another can be too hot. The PROsync™ system allows you to add wireless remote sensors throughout your home, providing a more accurate reading of the temperatures in individual rooms.

    PROsync Installation

    1. Choose the equipment module location.

    2. Remove the front cover and attach the equipment module to the wall.

    3. Wire the equipment module to the air handler.

    4. Snap the cover back on. The C terminal light should be illuminated, indicating the equipment module is powered.

    5. Install batteries in the main thermostat and ensure it is communicating with the equipment module. Any changes to the main thermostat that create a call will now be displayed at the equipment module in the LEDs associated with the terminals.

    6. Choose the install location for the T755WHO. In the tech settings, check the “Signal Strength” tech setting and ensure the value is greater than zero.

    7. Remove the subbase and attach it to the wall using screws and anchors in the box.

    8. If you want to hardwire the thermostat, connect the R and C wires.

    9. Snap the thermostat onto the subbase. Make sure the connection is secure, and the display is illuminated.

    10. Add any additional remote sensors as desired.

    PROsync Features and Settings

    Scheduling with PROsync

    With scheduling the system, you can make different rooms in control for each part of the day. For homeowners with predictable schedules, this ensures each room will be the target temperature when scheduled to be used. Making the kitchen in control in the morning, your home office during the day, your living room in the evening, and your master bedroom at night is a great hands-free approach to maximize comfort.

    Occupancy with PROsync

    This is an excellent solution for a home with multiple occupants. Each time a remote senses occupancy, it starts an automatic internal timer. The system is controlled using the average temperatures from only the remotes with active timers. When a remote’s timer expires, the system removes that remote from the average.
