LCD EWP/FAN DIGITAL CONTROLLER

Description

The unique LCD EWP/Fan
Digital Controller will manage
the operation of your chosen
EWP by varying the speed of
your pump in response to
coolant temperature and manage
control of your electric
Thermatic Fan, No need for a
separate thermal switch. The
Controller varies the speed of
your EWP looking for, and
locking onto your target temp.
If the engine temp goes 3
degrees C over the target, the
Controller will run your
radiator fan until the target
temp is restored. And it now
does 12 & 24 Volt

This
LCD EWP/Fan Digital Controller
(Part #8000) is Australian
designed and as part of this
Australian manufacturing
company’s continuous
improvement program this
advanced Digital Controller
boasts a suite of
enhancements.

These
include:

• The prominent blue Liquid
  Crystal Display screen
  (pictured)
• Now
  suitable for all 12v & 24v
  electrical systems, with
  relevant
  displays
• Genuine
  Thermometer, with coolant and
  targeted/set temp.
  displays
• Diagnostic

  has reduced to -10◦C (-14F)
  below set/targeted temp
  whichever occurs
  first.

The updated
Davies, Craig LCD EWP/Fan
Digital Controller (#8000) as
an engine management component
has undergone extensive
research, development, vehicle
and test centre
scrutiny.

The updated
LCD Digital Controller how has
two specific functions. This
unique Controller will now
manage the operation of the
EWP by varying the speed of
the EWP® in response to the
temperature of the engine and
manage control of your
electric engine fan. The
Controller has a push-button
on the facia panel that offers
target temperatures, 60ºC
(140°F) 65ºC (150°F) 70C
(160°F) 75ºC (165°F) 80ºC
(175°F) 85ºC (185°F) 90ºC
(195°F) 95ºC (205°F).
Generally, higher engine
temperature will offer
improved fuel efficiency and
lower engine temperature more
power. The LCD Digital
Controller will now operate
the engine’s electric fan
automatically once the engine
has reached +3c above the
target temperature. A
significant benefit too is the
Controller allows the EWP to
run on after ignition shutdown
to reduce heat soak. It is
recommended that engine
operational temperatures be
checked with
manufacturer.

The LCD
Digital Controller can be used
with our EBP however it is not
recommended as it will not
vary the speed of the pump in
response to temperature but
rather simply turn the pump on
and off once the top end
temperature is reached. For a
far more economical &
appropriate solution, we would
recommend Part Number 0401 &
0444 to turn the EBP on and
off at your set
temp.

Note:
This controller
(Part No. 8000) is set up for
negativley earthed systems
however with a wiring
adjustment, can also handle
positive earthed systems.
