Hoffman Controls 816-10DH Head Pressure Control 10A 24V/120-600V

A head pressure controller made to maximize effectiveness and safeguard your HVAC system is the Hoffman Controls 816-10DH. This little unit uses condensers with 120–600V, and 10A motors and runs on 24V AC. It regulates head pressure in low ambient settings by varying the condenser fan speed dependent on the temperature of the liquid line. The 816-10DH prevents excessive subcooling, which can result in decreased system performance and possible damage, by regulating airflow through the condenser. This results in decreased energy expenses, longer equipment lifespans, and better system performance all around. Put simply, the 816-10DH looks out for your HVAC system like a smart protector.
