HONEYWELL W7459A1035 Economizer Logic Module (works with M7415 Damper Actuators). W7459 Solid State Economizer Logic Module are used with M7415 and M8405 Dedicated Economizer Actuators to proportion outdoor and return air dampers in economizer systems.
• Attaches to one side of actuator for proportional control of damper.
• Combines solid state changeover control, minimum damper position potentiometer and compressor staging relays.
• 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.
