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.
FeATureS
• 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.
