• Page 4: Introduction Budderfly thermostat regulates temperature in heating or cooling systems by measuring the current temperature and comparing it to a set temperature, called the setpoint. The thermostat has internal temperature and humidity sensors and can connect to an external temperature sensor. When the current temperature deviates from the setpoint, the thermostat sends a signal to adjust the heating or cooling system. It is powered by 24 VAC, can control 2 cooling and 3 heating stages, and has Wi-Fi connectivity. The thermostat can be locked with a pin and allows for remote temperature control through Budderfly apps. It can be programmed with different setpoints for different times of the day and for 7 days. Manual override options are available for immediate temperature adjustments. Systems Compatibility The Budderfly Thermostat BTS-U1 operates with low-voltage heating and cooling systems only. It supports multiple system types, including gas heating, oil heating, electric heating, traditional AC, heat pumps, dual fuel systems, boilers, floor heating systems, and fan coil units.
