though the GP600 series is generally preferred for non-steam media

providing reliable cut-out and pump-down control by opening the circuit when pressures exceed or fall below your specific setpoints

Engineered as an auto-reset furnace limit

It is primary used for heating cutout or high-limit applications

typically accepting 0-10VDC or 2-10VDC inputs to position the drive accurately across its full rotation
