Description:
- Controls operation of the economizer outdoor air damper to provide free cooling on a signal from the cooling thermostat
- Provides accurate solid state enthalpy changeover control in a corrosion-resistant plate-mounted package
- Provides greater economizer savings when optional differential changeover control is used with an additional C7400 sensor (L40-008) mounted in the return air duct
- Consists of a W7459A Solid State Economizer Logic Module and one C7400 Solid State Enthalpy Sensor on a mounting plate
- Mounting plate matches plate-mounted H205A enthalpy controls for easy replacement
- Mounts in any position inside an economizer unit
