monitoring internal temperatures to prevent winding burnout during voltage spikes or locked-rotor conditions

providing a hard break in the safety circuit when internal plenum temperatures exceed the factory-defined threshold

Code Compliance: Facilitates adherence to ventilation standards by ensuring proper clearance for exhaust discharge

It maintains the same DPDT pin configuration and 24VAC coil requirements

Compact footprint maximizes rail space

White-Rodgers F89-0148 Well monitoring internal temperatures to preventThe White Rodgers F89 0148 is a professional grade immersion well designed for seamless integration with hydronic control systems. Engineered with a 1 2" NPT standard shank, this well provides a robust pressure sealed interface between the system fluid and the temperature sensing bulb, preventing leaks while ensuring high thermal conductivity for precise response times. This model is specifically sized for hydronic controls requiring a bulb dimension
