Ordering Information - Honeywell C7046C Product Data

SOLID STATE ECONOMIZER SYSTEM
M7415 and M8405 Damper Actuators are 25 lb-in. spring
return damper actuators that provide modulating or three-
position control of economizer systems, ventilation dampers
and combustion air dampers used in residential or
commercial HVAC equipment.
• M7415 Damper Actuator provides modulating
control of economizer dampers from a thermistor
mixed-air or discharge sensor to maintain 56°F
(13°C) air temperature.
• M8405A Damper Actuator provides three-position
control: closed, adjustable mid-position, and open.
• Quiet, high efficiency drive motor.
• High impact, glass-fiber reinforced, plastic case is
rugged, lightweight and corrosion resistant.
T6031H Thermostat acts as changeover thermostat.
• Switches enclosed to resist effects of dust and
moisture.
• Warmer-Cooler temperature scale.
• Sensing bulb installed in return air flow.
W7459A,C,D Solid State Economizer Logic Module used
with C7400 Solid State Enthalpy Sensors and M7415 or
M8405 Damper Actuators to proportion outdoor and
return air dampers for economizer control in commercial
HVAC equipment.
• Combine functions of solid state enthalpy changeover
control, minimum damper position potentiometer
(W7459A,D) and compressor staging relays.
• Optional differential enthalpy control provides greater
economizer savings than single enthalpy control by
selecting the most economical air for cooling.

Differential enthalpy control utilizes two sensor inputs:
one in return air and one in outdoor air; the
economizer control then determines which air has the
lower enthalpy.
• Solid state control package provides improved
accuracy, reliability and stability.
• W7459A,D mounts on M7415 Damper Actuator and
accepts inputs from C7150B Mixed Air Sensors,
C7400 Solid State Enthalpy Sensors, C7046C
Discharge Air Sensor, and optional remote minimum
damper position potentiometer.
• W7459C mounts on M8405A Damper Actuator and
accepts inputs from single pole single throw (spst)
mixed or discharge air control and C7400 Solid State
Enthalpy Sensors.
• Packages are designed to operate from the cooling
space thermostat to provide a totally integrated
control system.
• Housed in high-impact, glass-fiber reinforced plastic
case that matches the lines of M7415 and M8405
Damper Actuators.
• Quick connect terminals.
• Enthalpy setpoint (A,B,C,D) located on W7459 Solid
State Economizer Logic Module is used to select
combination of air temperature and humidity that is
suitable for free cooling.
• W7459A,D include built-in adjustable minimum damper
position potentiometer that controls the amount of
outdoor air admitted to meet minimum ventilation
requirements; include terminals for connecting
optional remote minimum position potentiometer.
• LED on W7459 indicates free cooling is available when
there is a call for cooling from the thermostat.
