W7212, W7213, W7214 ECONOMIZER LOGIC MODULES

SPECIFICATIONS

Models: W7212A, W7213A, W7214A Logic Modules: for use
with any Honeywell 2-10 Vdc actuator; includes DCV
(CO2) input; adjustable exhaust fan setpoint.
NOTES:
— All models include a minimum damper position
potentiometer, and setpoints for: enthalpy or
dry-bulb, occupied/unoccupied control, DCV
(CO2) operation, CO2 sensor failure mode and
DCV maximum (DCV MAX).
— Occupied/Unoccupied overrides minimum
damper position setting when building is
unoccupied.
— On CO2 sensor failure the damper outdoor
damper defaults to DCV maximum position. See
table 1 for economizer functions based on occu-
pancy, CO2 input and damper positions for
adjustments of potentiometers for MIN POS and
DCV MAX. This feature was added with series 2
version of the product; series 1 does NOT default
to DCV MAX, series 1 defaults to MIN POS on
failure of CO2 sensor.
Dimensions: See Fig. 1.
Electrical Ratings:
Input Voltage: 24 Vac ±20%; 50/60 Hz (Class 2).
