Econo min pos
Minimum Fresh Air Damper/Economizer Position
Default value: 0%
Minimum fresh air damper position. Effective only in Occupied
mode (Fan is ON). This value is also used to determine the fresh
air damper position based on the Min/Max CO2 and Min/Max
Pos values set. See Fresh Air Damper Position section for more
details.

Econo max pos
Maximum Fresh Air Damper/Economizer Position
Default value: 100%
Maximum fresh air damper position. Effective only in Occupied
mode (Fan is ON). This value is used to determine the fresh air
damper position based on the Min/Max CO2 and Min/Max Pos
values set. See Fresh Air Damper Position section for more
details.

Note: Viconics RTU HP IAQ Room Controller products and documentation for air damper position and output is based on 0-10 VDC
analog actuators. Many installations utilize 2-10 VDC actuators, which cannot be switched to 0-10 VDC control logic. The following
chart indicates the appropriate equivalent damper positions for use with 2-10 Vdc actuators.
