• 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) W7210 Solid State Economizer Logic Module controls the combination of air temperature and humidity suitable for free cooling.
• 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. |
