• Page 3: Important safety information is crucial for the safe installation of the thermostat. It is your responsibility to ensure compliance with all applicable codes and standards. Improper installation and maintenance can lead to damages and personal injury. The safety-alert symbol indicates potential hazards that could result in serious injury or death. Electricity, electrocution, and shock hazards are highlighted by specific pictorials. Certain symbols identify risks that could lead to minor injuries or property damage. Read the manual and all product labels before using the equipment. Keep the manual accessible for all users. The thermostat is not intended as a primary limit control; certified safety limits must be used. Attempting to service the thermostat voids the warranty.
• Page 4: Installation preparation requires specific tools such as a wire stripper, drill, and screwdrivers. Materials needed include 18 AWG LVT solid wire for low voltage connections. Choose an installation location that is an interior wall and keep it dry to avoid leakage onto the control. Ensure the relative humidity is less than 90% in a non-condensing environment. Avoid exposure to extreme temperatures beyond 32-122°F (0-50°C). Position the installation away from drafts, direct sunlight, and sources of electrical interference. Ensure easy access for wiring, viewing, and adjusting the display screen. The recommended height for installation is approximately 5 feet (1.5 m) off the finished floor. The maximum length of wire for connections is 500 feet (150 m). Strip wire to 3/8 (10 mm) for all terminal connections using standard 8 conductor, 18 AWG wire.
• Page 5: Removing the thermostat base involves pulling the lower half of the display front towards you to pivot it away from the base. To prevent the risk of personal injury and/or death, ensure power is not applied to the thermostat until it is fully installed and ready for final testing. All work must be done with power to the circuit being worked on turned off. Local codes may require this thermostat to be installed or connected by an electrician.
• Page 6: The W561 WiFi thermostat operates a radiant floor heating system. The thermostat uses the built-in air temperature sensor.

• Page 10: Sequence of operation outlines the heating operation and settings. The heating setpoint can be set from 40 to 95°F (4.5 to 35°C). Heating for freeze protection is provided whenever the air or floor temperature falls below 40°F (4.5°C). The W1 relay is on when the air temperature falls 1.5°F (1°C) below the Heat To setting. When Radiant Floor Heating is selected, the W1 relay operates using Pulse Width Modulation. The thermostat can measure room temperature between -46 to 212°F (-43 to 100°C). The thermostat can measure floor temperature between -46 to 212°F (-43 to 100°C). A floor minimum can be used to prevent a fast drop in temperature caused by receding solar exposure. Setting floor minimum and maximum temperatures enhances comfort while protecting floor coverings. The heating system can automatically shut off based upon the outdoor temperature and the WWSD setting.
• Page 11: User interface features a home screen that displays time and temperature after 60 seconds of inactivity. Users can swipe to view weather, outdoor temperature, current temperature, floor temperature, and heat to setting. The thermostat allows changing the operating mode through menu selection options such as heat, off, and away. Temperature adjustment can be made by touching or adjusting the displayed temperature. The WiFi status indicates if the device is connected. The hold feature overrides the programmed schedule until the specified time. Saving to schedule applies the new temperature to the current schedule event.
• Page 12: User settings allow for energy savings when the building is unoccupied. The Away setting can be selected on a thermostat or mobile app, affecting all linked devices. The Away temperature can be adjusted in the Setup / Temps menu. The schedule includes program days and specific temperature settings for different times of the day. Early Start anticipates the time required to heat a room and starts early. The schedule can be set to On to follow the programmed settings or Off for a constant temperature. Users can create a new schedule through the Schedule Setup option. The option to skip a temperature change is available if desired. Users can set the schedule start time and heating temperature for specific periods. The current group of program days can be navigated through the interface.
