the positioning relay must be ordered separately

though specific close-off ratings are dependent on the actuator force and the system's static pressure

the 17J61 Lennox propeller features a 1/2-inch bore for direct mounting to the motor shaft and operates with a clockwise (CW) rotation (facing the discharge)

Pressure ranges are determined by the internal spring color

This potential relay kit is compatible with a broad range of refrigeration compressor electrical parts

Resideo ZD16X14TZ Damper R-22 the positioning relay must beThe Resideo ZD16X14TZ is a professional grade parallel blade zone damper designed for demanding forced air zoning applications. This 16" wide by 14" high rectangular damper utilizes a 24Vac power closed spring return open configuration, ensuring fail safe ventilation should power be lost. The integrated synchronous motor is mounted on the 14" side, providing high torque operation to move the parallel blades efficiently against static pressure.
