Mechanical Thermatic® Fan Switch & Relay (12V & 24V) for Air Conditioning can be used with our Thermatic Fans & EWP's.
The Mechanical Thermatic® Fan Switch & Relay (12V & 24V) for Air Conditioning can be used with our Thermatic Fans & EWP's. It senses the coolant temperature after it passes through the engine block prior to entering the radiator and is adjustable from 40° to 100°C (104° to 212°F). The Thermal Switch is mounted near the radiator and the stainless steel probe fitted inside the radiator hose. The Thermal Switch & relay kit enables a fan to operate both thermally and also when the air conditioning is running.
24 Volt Application: Kit sold in 12 volt configuration, for 24 volt application, you will need to purchase 24 volt relay for each electric fan. Simply search for part 10534 on our website search bar

*Note: if using this switch for use with our EWP's, it will not vary the speed of the pump in response to engine temperature but rather turn the pump on and off at your set temperature. For EWP control, we would recommend the LCD Controller part number 8002 which can manage both the EWP and your Thermatic Fans.
