• Input from DCV C02 sensor provides optimum ventilation based on occupancy.
• All models include air change and shutdown; "A" models also provide prepurge.
• Demand control ventilation economizer provides comfort, energy savings, reliability, air quality compliance and application flexibility in heating, cooling and ventilating applications.
• Combines solid state enthalpy or dry bulb changeover control, minimum and maximum damper position potentiometer and DCV setpoint functions.
• Optional differential enthalpy control (enthalpy setpoint D with two C7400A sensors) provides greater economizer savings and maximum comfort over single enthalpy control by selecting the most economical method for cooling.
• Enthalpy setpoint (A-D) on economizer module controls the combination of air temperature and humidity that is suitable for free cooling.
• LEDs indicates when economizer is in free cooling and DCV modes.
• B models provide for input from an outdoor air quality sensor.Enhanced Economizer Logic Modules, 2-10 Vdc to Actuator| Approvals, Others | Complies with California Title 24 |
