The IAQ020X Control Package comes standard with the IAQ50X Air Measuring Station. Combined, the IAQ020X and IAQ50X offer a complete turnkey solution for measuring and controlling the minimum outside air to ASHRAE Standard 62.

The complete assembly (including IAQ50X air measurement damper, 24 VAC MS75XXIAQ actuator and IAQ020X control panel) is factory commissioned and calibrated to insure overall compatibility. The actuator is calibrated at multiple points along the 90° cycle. The control module utilizes the actuator feedback to confirm damper position and calculate the CFM (l/s) output based on both pressure and damper blade position. CFM (l/s) setpoint control with a 0-10 VDC input from the BAS. Provides a 0-0 VDC output that is proportional to the CFM (l/s) and modulates the damper position to maintain setpoint CFM (l/s) value.
