The York S1-025-41330-000 is a Single-Pole, Single-Throw (SPST) freezestat designed to provide dependable low-temperature safety protection for HVAC air handling units, coils, and related equipment. When supply air or coil temperatures drop to a dangerous level, this freezestat opens its circuit to shut down the system and prevent costly freeze damage.
How It Works
This freezestat monitors ambient or discharge air temperature and acts as a safety limit control. When temperature falls to the open setpoint, the switch opens and interrupts the control circuit, triggering a system shutdown. Once the temperature recovers to the close setpoint, the switch resets and normal operation can resume.
