Supported Applications

ACI Thermistor Room Series sensors are documented for indoor room temperature measurement and building-management-system connections. The source describes wall or junction-box mounting in areas with good air circulation.

Operating Conditions & Performance

The series uses thermistor sensing and screw terminal blocks. Source material documents four-way air-flow enclosure design and an optional foam pad for insulation from thermal drafts within a wall or wall surface.

Configuration Options

  • Documented configurations include beige or white enclosure styles, setpoint, after-hours override, communication-jack, and LCD options.
  • Available connection and mounting accessories include mounting plates, locking covers, thermostat guards, and the foam insulation pad.

Key Product Differences

Product variations differ by enclosure style, sensor configuration, display option, setpoint or override selection, and communication connection. LCD-option details remain option-specific.
