ASI-M carries a variety of field devices or sensors. The WS Series temperature sensors feature options for local communication connection, afterhours override pushbutton, and/or a linear potentiometer for variable user adjust of temperature setpoints. All temperature sensors are equipped with a precision 3000 Ohm thermistor matched with a built-in look up table present in our entire line of controls

The following are the range of temperature sensors that we offer :

WS-051 temperature sensor includes a digital display. It connects to the ASIC/1-8655 or specially configured ASIC/1-8055 VAV controllers to display current temperature and to allow the end user to change the occupied temperature setpoints within a configurable range.
