temperature is compared to an adjustable setpoint selected
on the control. If the outdoor-air temperature is above the
setpoint, the EconoMi$er IV will adjust the outside air
dampers to minimum position. If the outdoor-air
temperature is below the setpoint, the position of the
outside air dampers will be controlled to provided free
cooling using outdoor air. When in this mode, the LED
next to the free cooling setpoint potentiometer will be on.
The changeover temperature setpoint is controlled by the
free cooling setpoint potentiometer located on the control.
See Fig. 87. The scale on the potentiometer is A, B, C,
and D. See Fig. 88 for the corresponding temperature
changeover values.

Differential Dry Bulb Control
For differential dry bulb control the standard outdoor dry
bulb sensor is used in conjunction with an additional
accessory
dry
bulb
sensor
(part
number
CRTEMPSN002A00). The accessory sensor must be
mounted in the return airstream. See Fig. 90. Wiring is
provided in the EconoMi$er IV wiring harness.
See Fig. 83.

Fig. 90 -- Return Air Temperature or Enthalpy Sensor Mount-
ing Location
In this mode of operation, the outdoor-air temperature is
compared to the return-air temperature and the lower
temperature airstream is used for cooling. When using this
mode of changeover control, turn the enthalpy setpoint
potentiometer fully clockwise to the D setting. See Fig.
87.
Outdoor Enthalpy Changeover
For enthalpy control, accessory enthalpy sensor (part
number HH57AC078) is required. Replace the standard
outdoor dry bulb temperature sensor with the accessory
enthalpy sensor in the same mounting location. See Fig.
90. When the outdoor air enthalpy rises above the outdoor
enthalpy changeover setpoint, the outdoor-air damper
moves to its minimum position. The outdoor enthalpy
changeover setpoint is set with the outdoor enthalpy
setpoint potentiometer on the EconoMi$er IV controller.
The setpoints are A, B, C, and D. See Fig.91. The
factory-installed 620-ohm jumper must be in place across
terminals S
R
and SR+ on the EconoMi$er IV controller.
