ECONOMI$ER2 CONTROLLER WIRING AND
CONFIGURATION
Outdoor Air Enthalpy or Dry Bulb Sensor — The Econo-
Mi$er2 controller accepts input from either an accessory
enthalpy sensor or dry bulb sensor. When using differential
sensing, both sensors must be the same type. The outdoor air
sensor is wired to terminals S
O
and + on the EconoMi$er2 con-
troller. See Fig. 25.
When the outdoor air enthalpy rises above the outdoor
enthalpy changeover set point, the outdoor-air damper moves
to its minimum position. The outdoor enthalpy changeover set
point is set with the outdoor enthalpy set point potentiometer
on the EconoMi$er2 controller. The set points are A, B, C, and
D. See Fig. 30. The factory-installed 620-ohm jumper must be
in place across terminals S
R
and +. See Fig. 25.
Differential Dry Bulb — For differential dry bulb control the
standard outdoor dry bulb sensor (refer to Table 3) must be
replaced with two CROASENR001A00 sensors. One must be
placed in the return air and the other in the outdoor air stream.
An outdoor-air sensor can be mounted in any orientation
that exposes it to freely circulating air and protects it from rain,
snow and direct sunlight. Connect it to the S
O
terminal and to
the + terminal. The second sensor should be mounted in the
return airstream. Connect it to the S
R
terminal (after removing
the 620-ohm resistor) and to the + terminal on the controller.
See Fig. 25.
Differential Enthalpy — For differential sensing, the Econo-
Mi$er2 controller uses two enthalpy sensors, one in the outside
air and one in the return air duct. The EconoMi$er2 controller
compares the outdoor air enthalpy to the return air enthalpy to
determine EconoMi$er2 use. The controller selects the lower
enthalpy air (return or outdoor) for cooling. For example, when
the outdoor air has a lower enthalpy than the return air, the
EconoMi$er2 opens to bring in outdoor air for free cooling.
IMPORTANT: The optional EconoMi$er2 with 4 to
20 mA actuator signal control does not include the
EconoMi$er2 controller. The EconoMi$er2 actuator is
operated by a 4 to 20 mA signal from an existing field-
supplied controller (such as PremierLink control). See
Fig. 26 for wiring information.
