Description:

These sensors provide precision room temperature sensing for Energy Management Control Systems from the leading manufacturers. Three low cost Room Temperatures Sensors to choose from high precision thermistor or RTD, accurate to 0.2°C (±.36°F) over the range of 0°C to 70°C . The platinum RTD is accurate to 0.5°C  The enclosure design allows for use in areas where appearance is important. The sensors save I/O space on the DDC controller by connecting to a single input. User button activity is captured in the DDC system application programs as high and low going pulses, providing full software control of the button actions. RTS2 have removable terminal blocks.

Installation:

The unit is located on an interior wall, away from windows, supply ducts and heat sources. The enclosure can be mounted flush on the wall, or on an electrical box.

The backplate has holes for North American and European style electrical boxes. Two allen key screws on the bottom of the enclosure backplate are screwed inwards to allow the cover to be removed and outwards to hold the cover in place.

Calibration:

The series sensors use precision thermistors, so calibration is optional. The sensor routes the thermistor signal directly to the DDC controller, and also to an on board 8 bit A/D converter for local display of the temperature.

This A/D converter and associated circuitry can be calibrated by adjusting a potentiometer on the sensor. The potentiometer affects only the local display, not the thermistor signal at the DDC controller.
