manage the operation of your chosen EWP
your pump in response to coolant temperature and it will manage the on/off
control of your Thermatic
The Controller will run the EWP
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.

• When the cooling system is cold, remove top radiator hose and confirm that the inside diameter of your top radiator hose is between 30 to 42 mm prior to cutting hose. If the hose is more than 42mm, call Davies Craig and await 6mm sleeves. Page 5 of 12... - Page 6 • If the parts supplied (adaptor and/or sleeves) are suitable, select an appropriate location in a straight section of the hose then cut the radiator hose. • Temporarily slide radiator hose clamps on each end of the hose. Fit both cut ends of hose onto the In-line Adaptor (with or without sleeves as appropriate).

Do you have a question about the LCD EWP/FAN DIGITAL and is the answer not in the manual?
Questions and answers
Just installed new EWP (150) and digital controller (8001). Checked and rechecked all wiring: but screen only flashes on and off. Pump did start and stop but that is all. Unit receiving 12.1 volts Alarm sounding intermittently. No other indicators. Bought some time ago but this is first install .
The Davies Craig LCD EWP/FAN DIGITAL controller flashing on and off after installation could be caused by the following issues:
1. Blown Fuse: Check and replace the fuse if necessary.
2. Low Voltage: Ensure the controller is receiving sufficient voltage. For a 12V system, it should not be receiving less than 10.5V, and for a 24V system, it should not be receiving less than 21.5V.
3. High Voltage: Ensure the controller is not receiving excessive voltage. For a 12V system, it should not exceed 17.5V.
4. Wiring Connections: Inspect all wire connections to ensure they are secure and correctly installed.
