EWP & FAN DIGITAL CONTROLLER (MODULE ONLY) (PART #8102)
*NOTE: this part ONLY includes the controller and mounting hardware (bracket, nylon plate) for customers that may already have all other components due to replacing a damaged unit or upgrading from an older model.
For all other applications, please look at the full kit part number 8002.
The updated controller offers an enhanced rounded appearance, slimmer and the seven-pin plug is now safely tucked away, out of sight at the base of the Controller. It now also 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 / target temperature to eliminate heat soak.

The contrasting black & white screen and a comprehensive diagnostic menu of engine cooling management at a glance include;
- 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;
The 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.
