Application
This temperature control is commonly used in York air handling units, rooftop units, and other HVAC equipment where freeze protection is required. When ambient or coil temperatures fall to or below 26°F, the control opens the circuit to shut down the system and prevent coil freeze-up. Once temperatures recover to 38°F, the control closes and allows normal operation to resume.
