Wireless digital thermostats provide total freedom of thermostat placement to ensure the best control of a radiant heating system. The thermostat can send a demand for heating up to 98 ft. to a wireless base unit (through normal construction). The back-lit digital display can be configured to Fahrenheit (deg F) or Celsius (deg C) and shows when the area is actively heating. The thermostat's set point temperature range is adjustable from 41 to 96 deg F and it can be used with an optional floor sensor (sold separately). It uses two standard AAA batteries (included) and features a low-battery status.
