Pressure Fan Cycling Control w/ 1/4" External Flare Connector (100/400 psig)

P170 Controls for high pressure applications are designed primarily for high pressure cut-out control, head-pressure control, and condenser fan cycling control on commercial refrigeration and air conditioning applications.

Features:

• all-steel case and cover provides long lasting, rugged protection for internal components
• sight-set calibrated pressure adjustment displays a visible pressure scale, fully adjustable through the range without removing the cover (on NEMA 1 enclosure models)
• manual reset lockout option provides trip-free lockout that cannot be overridden or reset until pressure returns to specified level
• variety of available pressure connection styles allows greater flexibility when mounting control and adapting pressure connections to field application requirements

Applications:

• P170 Model with single-pole, single-throw (SPST) Open High switch action are the most popular models, and are typically used for high-pressure cutout.
• P170A model is available with SPST Open Low switch action, and typically are used for condenser fan cycling control.
• P170 model with single-pole, double-throw (SPDT), or four-wire, two-circuit switch action allow users to install alarm devices or other control circuits.
