The S541.RF provides remote reporting of door switch status, temperature, and humidity.
Most commonly, it is used as a wireless door switch transmitter to report door open and close status to the E-Series digital thermostat. It can also be used in conjunction with virtually any “dry contact” switch input to transmit closure information to the e4 thermostat. The S541 is designed to function even in a fluorescent light environment.
