PRODUCT DESCRIPTION
Thermatic® Digital Fan Switch DC0448 and 1/8" NPT Sensor
This versatile kit includes two sensors for maximum installation flexibility. It features a universal radiator fin probe and a professional 1/8" NPT thermal sensor, making it an ideal upgrade or replacement for DC0444 and DC0500 parts.
The switch supports 1 or 2 fans and works with 12V or 24V systems (24V requires DC10534 relays). Its intelligent logic activates fan 1 at the set temperature and fan 2 ten seconds later to prevent electrical interference and manage high cooling loads.
Dual Sensor Options & Features
Sensor 1 (Probe): Easy installation in radiator fins to detect air or coolant temperature.
Sensor 2 (1/8" NPT): Precise fit in engine block, thermostat housing, or radiator.
IP66 Protection: Completely dust-tight and protected against high-pressure water jets.
Wide Range: Fully adjustable from 40 °C to 110 °C (104 °F to 230 °F).
