The TAC MicroNet Sensor

TAC MicroNet Sensors are a family of digital room temperature sensors used with the
TAC MicroNet 2000™ Controllers. Available in three models, TAC MicroNet Sensors are
microprocessor-based and include industry standard thermistors for accurate room sens-
ing and plug-in communication jacks for the TAC MicroNet Controller Interface.
