Fastener Torque Values, Indoor Air Quality

Indoor Air Quality

If the optional indoor air quality sensor is installed, the RTU-MP will maintain indoor air quality within the space at the user configured differential setpoint. The setpoint is the difference between the indoor air quality and an optional outdoor air quality sensor. If the outdoor air quality is not present then a fixed value of 400ppm is used. The following conditions must be true in order for this algorithm to run:

S The mode is occupied.

S Indoor Fan has been ON for at least 30 seconds. S Indoor Air Quality sensor has a valid reading

As air quality within the space changes, the minimum position of the economizer damper will be changed thus allowing more or less outdoor air into the space depending on the relationship of the indoor air quality to the differential setpoint. If all the above conditions are true, the IAQ algorithm will run and calculates an IAQ minimum position value using a PID loop. The IAQ minimum damper position is then compared against the user configured economizer minimum position and the greatest value becomes the final minimum damper position of the economizer output.

If the calculated IAQ minimum position is greater than the IAQ maximum damper position configuration then it will be clamped to the configured value.

Demand Limit

If the RTU-MP receives a level 1 (one degree offset), 2 (two degree offset), or a 3 (4 degree offset) to the BACnet demand limit variable, the controller will expand the heating and cooling setpoints by the configured demand limit setpoint value and remain in effect until the BACnet demand limit variable receives a 0 value.
