W6210A,D and W7210A,D

Solid State Economizer Logic Module

APPLICATION

W6210A,D and W7210A,D Solid State Economizer™ Logic

Modules are used with solid state C7400 Enthalpy Sensors or

C7650A Dry Bulb Temperature Sensors and Honeywell Series

62 and Series 72 actuators to proportion outdoor and return

air dampers for economizer control in commercial HVAC

equipment.

FEATURES

• Operates from the cooling space thermostat to provide

a totally integrated control system.

• Solid state control package provides accuracy,

reliability and stability.

• Combines solid state enthalpy or dry bulb changeover

control, minimum damper position potentiometer and

compressor staging relay functions.

• Optional differential enthalpy control provides greater

economizer savings than single enthalpy control by

selecting the most economical air for cooling.

Differential enthalpy control uses two sensor inputs,

one in return air and one in outdoor air then

economizer control selects the air with the lower

enthalpy.

• Housed in high-impact, glass-fiber reinforced plastic

case.

• Enthalpy setpoint (A-D) on W6210 and W7210 Solid

State Economizer Logic Module controls the

combination of air temperature and humidity suitable

for free cooling.

• All models include a built-in adjustable potentiometer

to set minimum damper position and minimum amount

of outdoor air admitted to meet minimum ventilation

requirements. Terminals included for connecting

optional S963B1128 Remote Minimum Position

Potentiometer for remote damper control.

• LED indicates when free cooling is available.

• Mount on the sheet metal duct. Mounting screws

included.

• W6210A and W7210A accept inputs from discharge air

temperature sensors or mixed air temperature

sensors, and C7400 Enthalpy Sensors or C7650A Dry

Bulb Temperature Sensors and optional remote

minimum position damper potentiometers.

• W6210D and W7210D return to mechanical cooling

when outdoor air enthalpy reaches preset high limits.

W6210A,D AND W7210A,D SOLID STATE ECONOMIZER LOGIC MODULE Differential Enthalpy Changeover Setting higher temperatures for free cooling when humidity is low. The C7650A responds to only dry bulb temperature and should be used only in dry, arid climates. Differential enthalpy control uses two C7400 Enthalpy Sensors connected to one economizer module. The economizer compares outdoor air to the return air instead of to a set point (as with single enthalpy).
