The updated EWP®/Fan Digital Controller Part #8002( this is the updated unit which was #8001) will manage the operation of your chosen EWP® by varying the speed of your pump in response to coolant temperature and manage control of your electric Thermatic® Fan, No need for a separate thermal switch
The LCD EWP®/Fan Digital Controller has two specific functions. This unique Digital Controller will manage the operation of the EWP® by varying the speed of the pump in response to the coolant temperature and manage control of your electric engine fan. The Controller has a push-button to lock in any one of the nine targeted/set temperatures. It’s highly recommended you set/target the Controller to closely match your engine’s existing thermostat temperature. Generally, higher engine temperature will offer improved fuel efficiency and lower engine temperature more power. The Digital Controller will operate the engine’s electric fan automatically once the engine has reached 3°C (5.4°F) above the targeted (set) temperature. Another significant benefit is that the Controller allows the EWP® to run on after ignition shutdown to eliminate heat soak.
