The differential pressure transducer is connected to the DAP-III analog module to report the differential pressure across
the unit (between the supply and return air section). Three Sub-Menus must be programmed for proper operation. The
Sub-Menus are 3-18 (CONSTANT FAN SPEED FOR DX COOLING), 3-22 (MAXIMUM ALLOWABLE FAN SPEED) and
3-23 (MINIMUM ALLOWABLE FAN SPEED).

When started in the mode, the fan will fi rst operate at the programmed constant fan speed for 5 minutes. After the initial
5 minutes, the fan will proportionally increase or decrease the speed to maintain a constant static pressure setpoint as
follows:

• If the measured differential pressure is less than the differential pressure setpoint minus the differential pressure

deadband, the fan speed will increase 1% for each response time period until the differential pressure setpoint is
reached. The fan speed cannot exceed the maximum speed (set in Sub-Menu 3-22).

• If the measured differential pressure is greater than the differential pressure setpoint plus the differential

pressure deadband, the fan speed will increase 1% for each response time period until the pressure setpoint is reached.
The fan speed cannot be lower than the minimum fan speed (set in Sub-Menu 3-23).

• Otherwise, the fan speed will stay constant.

An optional discharge sensor is required for this mode. The discharge sensor will be used as a safety freeze thermostat.
If the discharge temperature falls below the discharge temperature limit setting, the fan will increase to the maximum
allowable programmed speed until the discharge temperature rises above the discharge temperature limit for 15 minutes.

FAN SPEED CONTROL FOR DIRECT EXPANSION (DX) UNITS WITH ENERGY SAVER

Three (3) plug fan speed control modes are available:

1. CONSTANT FAN SPEED
2. PROPORTIONAL FAN SPEED CONTROL BASED ON CW VALVE ACTION
3. CONSTANT STATIC PRESSURE CONTROL

• When in DX mode, allow the fan speed to vary the same as the same as the constant fan speed mode described

under DX cooling.

• When in Energy Saver cooling mode, allow the fan speed to vary the same as the proportional fan speed

control based on the CW valve action described for chilled water units.

• When in either DX or Energy Saver mode, allow the fan speed to vary the same as the constant static pressure

mode described under DX or CW depending on which cooling mode is being used.

An optional discharge sensor is required for this mode. The discharge sensor will be used as a safety freeze thermostat.
If the discharge temperature falls below the discharge temperature limit setting, the fan will increase to the maximum
allowable programmed speed until the discharge temperature rises above the discharge temperature limit for 15 minutes.
