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.
NOTE: To set the thermostat temperature control mode, go to “Installer setup (ISU)” on page 7.
Read before installing
NOTE: If an Optional Cover Plate is not required, see “UWP Mounting System installation” below. Use the Optional Cover Plate when you need to cover the paint gap from the old thermostat. There are different cover plates depending on when the thermostat was manufactured. One plate is square, the other is rectangular.
Use 3x supplied screws (#8 1-1/2 for red anchors and #6 1-1/2 for yellow anchors)
Set R Slider Tab.
NOTE: Slider Tabs for U terminals should be left in place for this thermostat model.
* Terminal can be jumped using Slider Tab. See “Setting Slider Tabs” on page 3.
NOTES Wire specifications: Use 18- to 22-gauge thermostat wire. A shielded cable is not required.
T6 Pro Hydronic thermostat is compatible with the following 10K ohm floor temperature sensors: AQ12C20 and AC112-01. The floor temperature sensor needs to be installed mid-way between the piping to ensure proper temperature reading (not over or right next to the piping). Example: For a 12″ pipe spacing install the sensor 6″ away from the piping and ensure the sensor is vertically centered. We recommend installing the floor temperature sensor inside of min. 0.5” PEX pipe. This simplifies future sensor replacement if required. In a small room, position the sensor in the center of the floor. In larger rooms, ensure the sensor is at least 7 feet from the wall.
Recommended floor temperatures settings
The recommended maximum floor temperature is 90 °F (32 °C) for most floor covering types except wood. Suggested maximum floor temperature for a wood floor is 85 °F (29.5 °C). Freeze protection temperature for garages and basements is suggested to be set between 41 °F – 45 °F (5 °C – 7.2 °C).
Available System modes:
– Heat
– Off
NOTE: A complete list of all setup (ISU) parameters and options starts below and continues through page 9.
