VT8600 Rooftop, Heat Pump and Indoor Air Quality Controller
Economizer Control Mode and Fresh Air Measurement Station
If the fresh air damper is to be used for both free cooling and minimum fresh air volume control (economizer mode and fresh air
measurement station, but without CO2 level control), only the Min FA parameter and the free cooling sequence will be active.
• The FA Range parameter should be set to a value higher than 0 CFM (0 CFM disables the fresh air control).
• Min FA (minimum fresh air) parameter should be set to the desired level.
The FA Range parameter value should be set to the maximum capacity of the fresh air measurement station. Therefore the relationship
between air volumes and input signals can be established. For example, if the fresh air station capacity is 10000 CFM, set FA Range to
10000.
This will set the relationship of 0 VDC = 0 CFM and 10VDC = 10000 CFM.
