QLD Davies Craig EWP Digital Controller

Chrispy · Feb 27, 2009

Well I bought two of these by mistake Retarded I know...

Davies, Craig now has an all new 'Digital' Electronic Controller to complement its range of universal fit Electric Water Pumps (EWPs).

This latest generation 'Digital' Controller allows you to electronically set the target temperature and it adjusts the rate of flow, hunting for and then locking onto, the temperature you set. The actual coolant temperature and other operational information is displayed at all times to keep you informed and in control.

To overcome the effects of 'heat soak' the Controller automatically continues to run the EWP after ignition OFF for a period of 2 minutes or until the coolant temperature is 5 degC below the target temperature, whichever occurs first.

This 'smart' Digital Controller has a range of diagnostic capabilities on-board, which will analyse and report the state of your cooling system.

As with all Davies,Craig products, the 'Digital' Electronic Controller Kit comes with everything you need for Do-It-Yourself installation. We have even included the option for installing the temperature sensor directly into the original thermostat housing or directly into the radiator inlet hose.

The EWP gives the most increased engine power and fuel saving per dollar spent-- and now the 'Digital' Electronic Controller puts in you in control.

The 'Digital' Electronic Controller senses coolant temperature and adjust the voltage to the EWP and thereby, the coolant flow. The algorithm in the controller has 3 distinctive phases of operation:

Phase A: The EWP pulses at 6V-- 10 sec.ON, 30 sec.OFF until coolant temperature is approx. 20 degC below the 'Set' temperature.

Phase B: The EWP pulses at 6V -- 10 sec.ON, 10 sec.OFF until coolant temperature is approx. 5 degC below the 'Set' temperature.

Phase C: The EWP is ON and supply voltage increases linearly with temperature from approx 5 degC below to 'Set' temperature. At 'Set' temperature the EWP is at full output.

Brand new in box, only opened to have a lookee see after I picked it up today.

$220 + post which is less than I paid...
