Description
The ACI 102482 is a commercial-grade freeze protection thermostat (freeze stat) engineered to safeguard HVAC air handling units, coils, and ductwork from freeze damage. Featuring a 20-foot averaging capillary, the unit senses temperature along the entire length of the capillary element — not just at a single point — making it ideal for monitoring large coil faces or wide duct sections where localized cold spots can occur.
Key Features
- 20-foot averaging capillary for wide-area freeze detection
- Manual Reset (M/R) operation — requires deliberate technician reset after a trip event, preventing automatic restart until the cause is investigated
- Single-pole double-throw (SPDT) switching action for flexible control wiring
- Designed for installation in air handling units, fan coil units, and ductwork applications
- Trips on low-temperature condition to shut down fans or open valves, protecting heating coils and refrigeration equipment
Application
The manual reset design ensures that once the freeze stat trips, the system remains off until a qualified technician investigates and manually resets the control. This prevents repeated freeze events and potential equipment damage. The SPDT output allows the device to be wired to open or close a circuit on a temperature drop, providing compatibility with a wide range of control panels and building automation systems.
