Congratulations on your purchase of the Davies, Craig EWP
®
/Fan Digital
Controller (PATENTS: USA 6425353, EU 1133624, AUS 756453). This Controller will
manage the operation of your chosen EWP
®
or EBP
®
by varying the speed of
your pump in response to coolant temperature and it will manage the on/off
control of your Thermatic
®
Fan.
The Controller will run the EWP
®
after ignition shutdown to dissipate
heat and avoid heat-soak.
The Controller has a push-button control to allow you to choose one of
nine set operating temperatures.
Generally, higher engine temperatures will offer improved fuel
efficiency and lower temperatures will increase power.
It’s recommended that engine operational temperatures be checked
against those nominated by your vehicle manufacturer.
