The EWP is a recirculating pump which is ideal for a'closed system' similar to an automotive cooling system; it is not'self-priming. Davies Craig 8002 LCD Controller for Electric Water Pump & Fans. 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 temperature from 60°C (140°F) to 100°C (212°F).
It's recommended you set/target the Controller to closely match your engine's existing thermostat temperature. 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 & Fan to run on after ignition shutdown for either 3 minutes or -10°C (-14°F) of set set / target temperature to eliminate heat soak. The LCD Digital Controller cannot be used with the smaller Electric Booster Pumps.
