Features

• C7400 solid state elements sense enthalpy (temperature and humidity); use two sensors for differential control, maximizing energy savings.
• Use one sensor in outdoor air for single sensor control; use two sensors, one in return air and one in outdoor air, for differential control.
• C7400 mount in any position up to 200 ft (61 m) away from Economizer Logic Module.
• UL94-5V enclosure.
