About This Product
Wi-Fi Control for Electric Floor Heating
The SunTouch® SunStat® CommandPlus™ is a Wi-Fi programmable touchscreen thermostat for controlling 120 V and 240 V electric floor heating systems. Remote access through the Watts® Home app allows homeowners to program schedules, adjust settings, and manage their floor heating system from a mobile device.
Floor and Air Temperature Control
CommandPlus can control heating based on floor temperature or room air temperature. It can also control floor temperature while limiting the maximum floor temperature to help prevent the space from overheating. A 15' floor sensor is included for floor-sensing applications.
Smart Scheduling and Energy Monitoring
Connected features include automatic clock setting, weather compensation, warm weather shut-down, energy-use monitoring, and email or text notifications. The thermostat also provides guided setup, help screens, voltage-level sensing, and flexible scheduling through its 4.3" touchscreen and Watts Home app.
Built-In GFCI and Relay Control
An integrated relay controls up to a 15 A resistive load, providing up to 1800 W at 120 V or 3600 W at 240 V. Built-in Class A GFCI protection provides a 5 mA trip level, and the thermostat can be wired to a SunStat® R4 Relay when additional control is required.
