The WiFi Thermostat 561 provides precise temperature control of a one-stage heating system. When connected to the Internet, the Watts(R) Home mobile app allows the thermostat to be controlled remotely. A 7-day, 4-event programmable schedule is available and the early start feature automatically learns to heat up the room by the scheduled time. An Away mode is quickly and easily accessed to provide energy savings when the space is unoccupied. The thermostat supports radiant floor heating and optional floor sensors can be installed to enhance comfort and protect floor coverings.
