29. If the AHU uses a proportional heating system (heating source level is
varied), continue with the next step. If the AHU uses a two-state
(heating is on or off) heating system, press “Heating Prop” so that
“Heating 2-State” displays.
30. If the AHU uses a proportional cooling system (cooling source level is
varied), continue with the next step. If the AHU uses a two-state
(cooling is on or off) cooling system, press “Cooling Prop” so that
“Cooling 2-State” displays.
31. If a pressure sensor is not used, continue with the next step. If a pressure
sensor is used, press “No Pressure” so that “Pressure” displays. (Note:
A pressure sensor must be installed and configured as an analog input to
FanMaster.)
32. If the AHU runs in demand ventilation mode (used in combination with
a CO
2
sensor to provide on-demand ventilation to maintain the
appropriate CO
2
level in the conditioned space), continue with the next
step. If the AHU runs in constant ventilation mode, press “Demand
Vent.” so that “Constant Vent.” displays (if a pressure sensor is installed,
constant ventilation mode cannot be used).
Note: Demand ventilation reduces the cost associated with cooling and
heating excessive outside air flows. Constant ventilation does not
reduce the cost associated with cooling and heating outside air flows
and is therefore only recommended for installations where the AHU
must maintain a constant flow of outside air.
33. If a CO
2
sensor is installed, continue with the next step. If a CO
2
sensor
is not installed, press “CO2” so that “No CO2” displays. Note: If you
have selected “Demand Vent.” in the previous step, and “No CO2” in
this step, “Demand Vent.” will be automatically changed to “Variable
Vent.” (i.e., demand ventilation cannot be selected when a CO
2
sensor is
not installed).
