Smart Sensor Series

The Smart Sensor Series combines an attractive display with a room temperature sensor to provide
users with a cost effective way to view or modify VAV box operation. It is designed for use with the Andover Controls i2 and b3 field controllers and can also accomplish many local control and monitoring tasks.

The standard Smart Sensor provides an LCD display and a 6 button programmable keypad that enables operators and occupants to change setpoints, monitor occupancy status and turn equipment on and off. An alternative version of the Smart Sensor is also available with a 4-button keypad.

The function keys can be custom programmed to perform a wide variety of functions, including switching a specific zone to occupied mode, signaling an alarm condition, adjusting the amount of override time, arming or disarming a security system, and enforcing password security. Programming the display and function keys is done with Andover Continuum’s Plain English® programming language.

The Smart Sensor comes in a well-ventilated plastic enclosure. The active sensing element is a highly stable, precision thermistor, accurate to within ± 0.36 °F (± 0.2 °C). The sensor has an operating range of 32 to 105 °F (0 to 40 °C).

Both versions of the Smart Sensor provide a connection for the Andover Continuum RoamIO-2 Lap-Top Service Tool.
