 HONEYWELL W7460A1008 Economizer Logic Module with analog input from one Indoor Air Quality sensor (commonly Carbon Dioxide Sensor) works with M7415 Damper Actuator. Use with C7400, or C7650 and C7150B or C7046 Sensors; indoor air quality (IAQ) sensor (2-10 Vdc); and Honeywell Series 72 actuators, or M7415 Damper Actuator to proportion outdoor and return air dampers for economizer and ventilation control in commercial HVAC equipment.Features Input from DCV sensor provides optimum ventilation based on occupancy. All models include air change and shutdown; "A" models also provide prepurge. Solid state 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 C7400 sensors) provides greater economizer savings and maximum comfort over single enthalpy control by selecting the most economical air for cooling. Enthalpy setpoint (A-D) on economizer module controls the combination of air temperature and humidity that is suitable for free cooling. High-impact, glass-fiber reinforced plastic case. LEDs indicates when economizer is in free cooling and DCV modes. B models provide for input from an outdoor air quality sensor.
