    The Network Thermostat NT-URS-ULE wireless remote sensor is a flexible sensor that can be used in several configurations including indoor temperature and humidity, indoor humidity only, outdoor temperature, or as any one of three auxiliary temperature sensors. Additionally, up to six (6), NT-URS-ULE sensors can be connected to a single thermostat for indoor temperature averaging.

    The NT-URS-ULE works wirelessly using the DECT/ULE protocol when connected to a NetX X5U or X7U Series thermostat with a NetX DECT/ULE daughter card.

    The sensor has an incredible range of up to several hundred feet and a battery life of approximately 2 years, depending on the configuration.
