BMS
When fan mode is set to BMS, the supply and exhaust fans will be controlled
by the building management system via modbus RTU or BACnet IP.
Additionally, the unit can only be enabled by the BMS or a wired enable
signal.
CO2
When fan mode is set to CO2, the supply and exhaust fans will modulate
based on a PID loop to maintain a specific CO2 PPM as defined by a PPM
set point. The supply and exhaust fans will each be bound by a global
minimum and maximum setpoint. The CO2 PPM level is calculated based on
a 0-10VDC input in conjunction with a minimum and maximum CO2 PPM.
The calculated CO2 level will scale linearly between the minimum and
maximum CO2 PPM set points based on the 0-10VDC input. By adjusting
the min and max CO2 PPM, the software can accommodate various third-
party CO2 sensors.
All setpoints besides the PID loop settings can be found within the fan control
setpoints menu. The PID loop settings can be found within the PID settings
menu. When scheduling is enabled, occupied and unoccupied supply,
exhaust, and CO2 PPM setpoints can be set.
PRESSURE
When fan mode is set to pressure, the supply and exhaust fans will modulate
based on a PID loop to maintain a specific duct or building pressure (IN W.C.)
as defined by a pressure set point. The supply and exhaust fans will each be
bound by a global minimum and maximum setpoint. The pressure level is
calculated based on a 0-10VDC input in conjunction with a minimum and
maximum pressure. The calculated pressure will scale linearly between the
minimum and maximum pressure set points based on the 0-10VDC input. By
adjusting the min and max pressure setpoints, the software can accommodate
various third-party pressure sensors.
All setpoints besides the PID loop settings can be found within the fan control
setpoints menu. The PID loop settings can be found within the PID settings
menu. When scheduling is enabled, occupied and unoccupied supply,
exhaust, and pressure setpoints can be set.
