Safgard OS-100 Outdoor Sensor W/3250-Plus & 3200-Plus 48-140

The Safgard OS-100 Outdoor Sensor is an outdoor temperature sensing part designed for boiler control system to provide accurate ambient response for reset and modulation operations. It works within a 48140F range and is used with compatible 3200-Plus and 3250-Plus controllers to optimize heating response based on outdoor conditions. The sensor transmits temperature data to the control system enabling more efficient boiler operation, and improved comfort regulation. Installed on exterior building surfaces, it supports system efficiency by aligning heating output with temperature changes in applications.
