C7400 Enthalpy Sensor and
C7660 Dry Bulb Temperature Sensor
W7212, W7213, W7214 Logic Modules accept signals from
either the C7400 Enthalpy Sensor or the C7660 Dry Bulb
Temperature Sensor. The W7212A, W7213 and W7214
models are used with the C7400A sensor and the W7212C
models are used with the C7400C sensor. The wiring is the
same for either sensor.
IMPORTANT
When using differential sensing, both sensors must
be of the same type (enthalpy).

ECONOMIZER
LOGIC MODULE
Demand Control Ventilation
The DCV CO2 sensor must provide a 0/2-10 Vdc output. The
DCV modulates the outdoor damper to provide ventilation
based on occupancy. The DCV potentiometer is adjusted to
provide ventilation based on the output of the CO2 sensor. The
DCV LED lights when the DCV signal is above setpoint. If the
CO2 sensor should fail, the W7212 will default to the DCV
maximum position which is the minimum position for design
100% occupancy of the space.

W7214 (CHANGEOVER TERMINAL O)
Connect the O terminal according to the following details:
— 24V power to O: System is in cooling mode.
— No power to O: System is in heating mode.
Remote Minimum Position Control
Remote control of outdoor air dampers is desirable when
requiring temporary additional ventilation. The addition of a
S963B1128 Remote Potentiometer allows occupants to open
or close the dampers beyond minimum position for modified
ventilation. Connect the potentiometer as shown in Fig. 5.
W7212, W7213, W7214 ECONOMIZER LOGIC MODULES
IMPORTANT
— The minimum position signal takes priority over the
DCV maximum position signal. With DCV maximum
set below the minimum, the logic module signals the
actuator to maintain the minimum position.
— Freeze protection logic takes priority over all signals.
For details, see the notes in the Adjusting Minimum
and Maximum Positions section.

OPERATION
The purpose of the economizer is to use outdoor air for
cooling, whenever possible, to reduce compressor operation.
Power at the N terminal determines the Occupied/Unoccupied
setting:
— W7212:
• 24 Vac (Occupied).
• No power (Unoccupied).
— W7213,W7214:
• 24 Vac (Unoccupied).
• No power (Occupied).
— See Fig. 9 through 15 for controller hookup.
NOTE: When module is operating in Occupied mode, the
minimum position is defined by the potentiometer.
When the module is operating in Unoccupied mode,
and there is no call for cooling, the damper drives fully
closed.
When wired as shown in Fig. 9 through 15, the logic module
responds to the cooling thermostat signal. The system uses
C7400 Solid State Enthalpy Changeover Sensor(s) or C7660
Dry Bulb Temperature Sensor(s). The C7400 responds to both
dry bulb temperature and humidity, allowing use of outdoor air
at higher temperatures for free cooling when humidity is low.
5
Economizer
W7213, W7214
W7212
W7212
The C7660 responds only to dry bulb temperature; use only in
dry, arid climates and only in single dry bulb changeover. Do
not use the C7660 in differential dry bulb applications.
The logic module functions as a true first stage of cooling
providing maximum energy economy during the cooling cycle.
It automatically locks out free cooling during heating; holding
the outdoor air damper at the minimum position setting.
The logic module can operate as either a basic free cooling
controller, or it can incorporate additional functions. Table 2
details the input/output (I/O) logic of the module.

For detailed assistance in minimum position selection
reference the Economizer Application Guide (form 63-8594)
Ventilation section. The following provides basic guidelines for
minimum position selection and adjustment:
IMPORTANT
• Adjust the minimum position potentiometer to allow
the minimum amount of outdoor air for building effluents, as required by local codes, to enter the building.
• This procedure requires use of a quality thermometer
capable of reading to 0.5°F [0.25°C].

When the mixed air sensor takes control based on
an increased requirement for cooling, it overrides
the DCV maximum position potentiometer and can
drive the damper full-open.
If the mixed air temperature drops to 45°F, the
mixed air sensor overrides the DCV and closes the
damper to protect from freezing the hot or chilled
water coils. Control returns to normal once the
mixed air temperature rises to 48°F. Some models
of the W7212 close the damper fully and others
close the damper to minimum position. Check the
label on the box for position of damper on freeze
protection. If the CO2 sensor should fail, the
W7212 defaults to DCV maximum, providing minimum ventilation for maximum design occupancy.

The logic module modulates the outdoor damper to provide
ventilation based on the 0/2-10 Vdc DCV. With no cooling
signal, the DCV overrides the outdoor air damper when
ventilation requires additional outdoor air.
Calculate the appropriate mixed air temperature, see
Equation 1.
Disconnect mixed air sensor from terminals T and T1.
Place a jumper across terminals T and T1.
Ensure that either the factory-installed jumper is in place
across terminals P and P1 or, if remote damper position
is required, that it is wired according to Fig. 5 and turned
fully clockwise.
Connect 24 Vac across terminals TR and TR1.
Carefully adjust the potentiometer on the face of the
device with a small screwdriver until the mixed air
temperature reaches the calculated value.
NOTE: Ensure that the sensed air is well mixed.
7.
Adjusting Minimum and Maximum
Positions
The minimum position potentiometer maintains the minimum
outdoor air flow into the building during the occupied period.
The minimum position provides ventilation for the building
effluents based on ASHRAE standard 62.1. The DCV
maximum position potentiometer allows the installer to set the
proper ventilation based on occupancy established by
ASHRAE standard 62.1. Setting the DCV maximum position of
the damper prevents the introduction of large amounts of hot or
cold air into the space by preventing the dampers from opening
100%.
If all minimum and maximum position adjustments are
complete, remove the T-T1 jumper and reconnect the
mixed air sensor.
Equation 1.Formula to aid minimum position adjustment.
( T O × OA ) + ( T R × RA ) = T M
Where:
TO = Outdoor air temperature
OA = Percent of outdoor air
TR = Return air temperature
RA = Percent of return air
TM = Resulting mixed air temperature
NOTE: The following sample calculation uses only
Fahrenheit temperature.
IMPORTANT
With the DCV maximum position set below the
minimum position, the minimum position overrides the
maximum position (negating most DCV functions of
the logic module, as the damper cannot move).

EXAMPLE:
Assume local codes require 10% outdoor air during occupied conditions, outdoor air is 60°F and
return air is 75°F. Under these conditions, what is
the temperature of the mixed air?
( 0.1 × 60°F ) + ( 0.9 × 75°F ) = 6.0°F + 67.5°F = 73.5°F
Mixed air will be 73.5°F when OA is 60°F and RA is 75°F with
10 percent outdoor air entering the building.

Disconnect mixed air sensor from terminals T and T1
and short terminals T and T1.
Connect a jumper between terminals AQ and SO+.
Connect 24 Vac across terminals TR and TR1.
Adjust the potentiometer on the face of the device with a
screwdriver for desired maximum position.
If all minimum and maximum position adjustments are
complete, remove the T-T1 jumper and reconnect the
mixed air sensor.
Differential enthalpy control uses two C7400 Enthalpy Sensors
connected to one logic module. The logic module compares
outdoor air to return air.
NOTE: Turn the enthalpy setpoint potentiometer fully clockwise to the D (or E setting for W7212C) setting.
The logic module selects the lower enthalpy air (return or
outdoor) for cooling. For example, when outdoor air has lower
enthalpy than return air, the module calls to open the outdoor
air damper to bring in outdoor air for free cooling.
Exhaust Setpoint
The exhaust setpoint determines when the exhaust fan runs
based on damper position. When the exhaust fan call is made,
the module provides a 60 ±30 second delay before exhaust fan
activation. This delay allows the damper to reach the
appropriate position to avoid unnecessary fan overload.
NOTES:

Enthalpy Changeover Setpoint
Outdoor Enthalpy Changeover Setpoint
(Single Enthalpy)
—
The outdoor enthalpy changeover setpoint returns the outdoor
air damper to minimum position when enthalpy rises above its
setpoint. Enthalpy setpoint scale markings, located in the
device, are A, B, C, and D for the W7212A, W7213 and
W7214. See Fig. 7 for the corresponding control point.
Enthalpy setpoint scale markings for the W7212C are A,B,C,D
and E. See Fig. 8 for the corresponding control points. The
factory-installed 620-ohm jumper must be in place across
terminals SR and SR+. Temperature and humidity points to the
left of the selected curve will allow the dampers to open for free
cooling.

EF and EF1 are 24V dry contacts only. An external
line voltage contactor is required to operate the
exhaust fan.
When the exhaust fan is deactivated the EF and
EF1 contacts open immediately.
Adjustable Exhaust Setpoint
These logic modules have an adjustable exhaust setpoint. This
potentiometer allows the installer to adjust the damper position
at which the EF and EF1 exhaust fan contacts are made.
NOTE: The 60 ±30 second delay allows the outdoor damper
to reach the exhaust setpoint prior to the EF and EF1
contacts being made.
