Digital Thermatic^® Fan Switch with 1/4" NPT Thermal Sensor Kit (Part #0445)

This kit comes with two sensors offering a variety of installation options for coolant temperature sensing.

Sensor 1: Temperature Probe (Air or Coolant Fitment): Senses air temperature as it passes through the radiator with the sensor placed in the radiator fin section. Alternatively, the sensor can also be placed directly into the coolant system in combination with a Temperature Sensor Adaptor Kit (Part #0409).

Sensor 2: 1/4" NPT Thermal Sensor Kit (Coolant or Oil Fitment): The thermal sensor can be placed into the thermostat housing, engine block, or directly into the radiator. If you would like to install this sensor in the top radiator hose, it can also be used with a Temperature Sensor Adaptor Kit (Part #0409).

The switch can run 1 or 2 fans and is compatible with 12 or 24-volt applications. It has an adjustable temperature range of 40°C to 110°C (104°F to 230°F), displayed in Centigrade or Fahrenheit.

• Fan #1: Starts once the temperature reaches the set temperature.
• Fan #2: If applicable, starts operation 10 seconds after Fan #1 and continues until the temperature falls by 5°C below the set temperature.

24 Volt Application: Kit sold in 12-volt configuration; for 24-volt application, you will need to purchase 2 x 24-volt relays.
