Optional Accessories
Autozero Module
The optional Autozero Module (see Figure Autozero
Module
) is required when continuous operation at
occupied flow is required for an area. The Autozero
Module is connected to the air velocity inlet ports of
the controller and provides periodic recalibration of
the air velocity transducer without changing air
volume being delivered to a room. This recalibration
ensures long-term precise airflow delivery.
Autozero Module Specifications
Power Consumption .75 VA @ 24 Vac max.
Dimensions 2" W x 1.51" H x 1.89" D
(58 mm x 78 mm x 29 mm)
Weight 1.3 oz. (36.9 g)
Autozero Module.
Differential Pressure Sensor
The differential pressure sensor is easily connected to
the box’s air-velocity sensing elements to provide
measurement of the differential pressure. The
measured value is converted to actual airflow in cfm
(lps) by the controller.
Differential Pressure Sensor Specifications
Temperature Range 32°F to 122°F (0°C to 50°C)
Measurement Range 0 to 5200 fpm (0 to 26 m/s)
Pneumatic Transducer
The PTS Pneumatic Transducer provides the signal
conversion from electronic to pneumatic. The module
is piped to the pneumatic actuator and wired to the
controller. This transducer provides for accurate
control of pneumatic actuators for precise
temperature and air volume control. See
