EWP - Electric Water Pump & Fan Digital Controller Kit

ELECTRIC WATER PUMP (EWP®) & FAN DIGITAL CONTROLLER KIT

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.

Sensor Wire Length: 250cm, Increase to 380cm (Oct 2020)

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) abovethe 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.
