York S1-025-27727-002 Temperature Control Overview

The York S1-025-27727-002 is an OEM temperature control designed for use in York HVAC systems requiring precise low-temperature switching. With an open point of 26°F and a close point of 38°F, this control is ideally suited for freeze protection and low-ambient temperature sensing applications. Its Single Pole Single Throw (SPST) switching configuration provides reliable, straightforward circuit control in a wide range of heating and cooling equipment.

Key Features

• OEM York replacement temperature control — ensures compatibility and reliable performance
• Opens at 26°F (OP26) — triggers protective shutoff or alarm at freeze-risk temperatures
• Closes at 38°F (CL38) — restores circuit once safe temperature is reached
• SPST (Single Pole Single Throw) switching — simple, dependable on/off circuit control
• Designed for freeze protection and low-limit temperature control in York HVAC equipment
• Direct OEM replacement for fast, accurate installation with no modifications required

Application

This temperature control is commonly used in York air handling units, heat pumps, and other HVAC systems where freeze protection is critical. The OP26/CL38 set points make it an effective low-limit safety device, opening the circuit when coil or air temperatures approach freezing and automatically resetting once temperatures recover to a safe level.
