ELECTRIC WATER PUMP & FAN DIGITAL CONTROLLER KIT (#8002)
Provides optimum control of Davies, Craig 12 / 24 Volt Electric Water Pumps and Electric Fans. Suits EWP®80, EWP®115, EWP®130, EWP®150, Thermatic® / Electric Fans and billeted style Electric Water Pumps.
The controller offers enhanced appearance, slimmer and the seven-pin plug is safely tucked away, out of sight at the base of the Controller. It has 2 mounting options:
- Bracket
- Nylon Plate
The EWP®/Fan Digital Controller has two specific functions:
- Will manage the operation of the EWP® by varying the speed of the pump in response to the coolant temperature
- Manage control of your electric engine fan.
The Controller has a push-button to lock in any temperature from 40°C (104°F) to 110°C (230°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 contrasting black & white screen and comprehensive diagnostic menu of engine cooling management at a glance includes;
- Numerical LCD exhibiting real-time numerical on-going engine & targeted/set temperatures
- Flashing EWP® logo signifying pump pulse, width, modulation (PWM) operation and delivering the desired coolant flow through the engine
- Individual, adjustable targeted/set temperatures from 40°C (104°F) to 110°C (230°F)
- Rotating Davies Craig Thermatic® Fan symbol indicating fan operation (which automatically engages at +3ºC (+37.4ºF) above the set/targeted coolant temperature.)
- Your set/targeted temperature can now be held in memory if the battery is disconnected.
- Override feature to assist with EWP® bleeding operation.
- Voltage output.
A suite of self-diagnostic ‘test’ functions are still on offer that identify and deliver visual and audible warnings enabling simple trouble-shooting if a system problem is evident. An audible alarm will sound when;
- * Coolant temperature doesn’t exceed 40ºC (104ºF) within 5 mins of start-up.
- * Coolant exceeds +10ºC (+50ºF) of set/targeted temperature.
- * Coolant temperature exceeds 100ºC (212ºF).
- * Voltage supply is either too high or too low.
- * EWP error.
- * Temperature Sensor error.
The LCD EWP®/Fan Digital Controller will manage the operation of your chosen EWP® or billeted electric water pump by varying the pump’s speed and subsequent coolant flow in response to engine coolant temperature, as well as manage the thermal control of your electric Thermatic® engine Fan/s.
The EWP®/Fan Digital Controller becomes the engine’s new ‘thermostat’ and now has individual targeted temperature settings from 60°C (140°F) to 110°C (212°F). Programmed by simply pushing a button and holding down to set!
In combination with a Davies, Craig Thermatic Fan®, or other electric engine fans, the temperature of the engine’s cooling system can be more precisely controlled. The EWP®/Fan Digital Controller will also operate the EWP® after ignition/engine shutdown, circulating coolant and rapidly dissipating heat more efficiently to avoid heat-soak.
If the engine temperature cools below the targeted/set temperature, the EWP®/Fan Digital Controller will step back from full system voltage back to 12 or 6 volt operation and revert to pulse width modulation (PWM) mode when highway cruising.
Major advances to the updated LCD EWP®/Fan Digital Controller are;
Temperature setting is a simple push-button adjustment. Individual set/target temperature options commencing at 60°C to 100ºC (212ºF). The EWP®/Fan Digital Controller is factory set at 85ºC (185ºF).
To eliminate heat-soak, a built in automatic time-out feature allows the EWP® to circulate engine coolant for up to 3 minutes or till coolant temperate is reduced to -10◦C (-14F) below the set/targeted temperature to eliminate heat-soak after engine shut-down.
Temperature Thermal Sensor - can be mounted into the thermostat housing, top radiator hose or top of the radiator or engine block near the engine coolant outlet.
The LCD EWP®/Fan Digital Controller weighs only 90 grams (3.2oz) and can be easily and conveniently mounted anywhere in the driving compartment.
The LCD EWP®/Fan Digital Controller can be left at the factory-set 85ºC (185ºF), offering smarter engine warm up and enhanced engine management of the vehicle’s cooling system. Many drivers may prefer to select a higher set point for an even quicker warm-up and greater economy, switching to a cooler engine setting when full power is required. It’s that simple.
Davies, Craig’s updated LCD EWP®/Fan Digital Controller continues to be a premium quality product ensuring its increasing range of EWP®s will exhibit the ultimate engine cooling experience. The LCD EWP®/Fan Controller was designed and developed right here in Australia! The Digital Controller, an EWP® and electric Thermatic® engine fan/s are three excellent examples of ingenious Australian innovation and design.
