FAN ONLY OPERATION
The Davies, Craig LCD EWP/Fan Digital Controller is programmed to earth the electric
fan relay at 3°C above the set point. The Controller will continue to operate the fan until
the coolant temperature is below the set point.
To enable fan only control without using an Electric Water Pump, connect the remote
LED (supplied) to the controller wires labelled “PUMP” as shown below
Please refer to the Figure 6 (page 9) for fan to controller wiring details. Please call
Davies, Craig at (03)93691234 if you require another remote LED to complete the
wiring.
