• Installation Instructions and User Guide
Welcome!
T6 Pro Hydronic Programmable Thermostat can be used
to control the ambient air temperature or floor temperature
or both. You can choose among the following temperature
control modes.
A mode: Controls and displays the ambient air temperature
only.
F mode: Controls and displays the floor temperature only
using an external floor temperature sensor. This control
mode is suitable for areas such as bathrooms where floor
temperature could be scheduled to be warm only during
occupied, morning and evening periods.
• Floor temperature is indicated by "FLR" above the actual
floor temperature.
• Actual ambient air temperature could also be displayed in
the Thermostat MENU/TEMP.
AF mode: Controls and displays the ambient air temperature
as well as maintains the floor temperature within desired
floor temperature limits using an external floor temperature
sensor. Setting the minimum and maximum floor
temperature limits is a way to enhance
comfort and to protect the floor covering at
the same time.
• Actual floor temperature could also be
displayed in the Thermostat MENU/
TEMP.
NOTE: To set the thermostat temperature
control mode, go to "Installer setup (ISU)"
on page 7.

  • How do I install the Honeywell T6 Pro Hydronic thermostat?

    To install the Honeywell T6 Pro Hydronic thermostat, follow these steps:

    1. If using the optional cover plate, separate the Junction Box Adapter from the Cover Plate.
    2. Mount the Junction Box Adapter to the wall or an electrical box using any of the eight screw holes. Insert and tighten mounting screws supplied with the Cover Plate Kit, ensuring the Adapter Plate is level.
    3. Attach the UWP by hanging it on the top hook of the Junction Box Adapter and snapping the bottom into place.
    4. Snap the Cover Plate onto the Junction Box Adapter.

    If not using the optional cover plate, for the UWP Mounting System:

    1. Turn the power off at the breaker box or switch. Open the package to find the UWP.
    2. Position the UWP on the wall, level it, and mark the hole positions.
    3. Drill 7/32" holes for drywall at the marked positions, then lightly tap supplied wall anchors into the wall.
    4. Pull the door open and insert the wires through the wiring hole of the UWP.
    5. Place the UWP over the wall anchors. Insert and tighten mounting screws supplied with the UWP until it no longer moves. Close the door.

    After mounting, push excess wire back into the wall opening and close the UWP door. Align the UWP with the thermostat and push gently until the thermostat snaps in place. Finally, turn the power on at the breaker box or switch.

  • Where can I find the wiring diagram for the Honeywell T6 Pro Hydronic thermostat?

    Wiring terminal designations and diagrams for conventional systems can be found in the manual, including:

    • Heat-only System (with floor sensor)
    • Heat-only System (power open zone valve)
    • Heat-only System (hot water relay panel with floor sensor)
    • Heat-only System (boiler with floor sensor)

    Wire specifications require 18- to 22-gauge thermostat wire; shielded cable is not needed. For power supply, disconnect means and overload protection are required. If using one wire for the R-Slider Tab, move it to the R setting. An optional 24 VAC common connection is also available.


    For more information, see page 4 of the manual.

  • Why is my Honeywell T6 Pro Hydronic thermostat displaying an error code?

    Active alerts are displayed via the alert symbol and alert number in the clock area on the home screen. You can read more information about active alerts, snooze, or dismiss non-critical alerts in MENU/ALRT. Some common alerts include:

    • 170: Internal Memory Error - The thermostat memory has encountered an error. Contact dealer for assistance.
    • 173: Thermostat Temperature Sensor Error - The thermostat's sensor has encountered an error. Contact dealer to replace the thermostat.
    • 177: Indoor Temperature Sensor Error - Wired indoor temperature sensor is not connected or there is a wiring short. Contact dealer for assistance.
    • 252: AC Power Lost - No AC power detected. Check the AC circuit breaker.
    • 405: Battery Low - Battery low. Turn the system mode to off and replace the batteries.
    • 407: Battery Critical - Battery critical. The thermostat cannot control your system. Replace the batteries immediately.
    • 514: Floor Temperature Sensor Failure - Wired floor temperature sensor is not connected or there is a wiring short. If configured for AF mode, the thermostat will still control ambient air temperature but ignore floor temperature limits. If configured for F mode, heating will stop, but if air temperature drops to or below freeze protection, heating will activate and control ambient air temperature.
    • 535: High Floor Temperature - The measured temperature is above the maximum floor temperature limit.
    • 536: Freeze Protection - The measured temperature is below the freeze protection temperature limit.

    For more information, see page 10 of the manual.

  • Can the Honeywell T6 Pro Hydronic thermostat be used with a radiant floor heating system?

    Yes, the T6 Pro Hydronic thermostat is designed to control floor temperature and is compatible with radiant floor heating systems. It can control and display the floor temperature using an external floor temperature sensor in F mode. The thermostat is compatible with 10K ohm Honeywell floor temperature sensors such as AQ12C20, AC112-01, and AC130-01. When installing, the sensor should be placed midway between the piping to ensure proper temperature reading, and it is recommended to install it inside a min. 0.5” PEX pipe for easier future replacement. In a small room, position the sensor in the center of the floor, and in larger rooms, ensure it is at least 7 feet from the wall.
