If ac ve, FP mode will work when the
water heater is both off and on.
FP mode will only work if the supply
voltage is above 12.5vdc (12vdc model) or
24.4vdc (24vdc model)
When the temperature of the water is
below 30C then FP mode ini ates. This
pulses a small amount of the current to
the element, stopping the water from
freezing.
When the temperature of the water is
above 30C the FP mode terminates.

VS mode will only work when the water
heater is switched on.
VS mode will only allow the water heater
to work when the supply voltage is above
12.5vdc (12vdc model) or 24.4vdc (24vdc
model).
If the supply voltage is below 12.5vdc
(12vdc model) or 24.4vdc (24vdc model)
then the water heater will not work un l
the supply voltage has increased to
12.5vdc (12vdc model) or 24.4vdc (24vdc
model).

If both VS mode & AS mode are switched
on then AS mode will over‐ride VS mode.

AS mode will only allow the water heater
to work when the supply voltage is above
13.2vdc (12vdc model) or 24.8vdc (24vdc
model).
If the supply voltage is below 13.2vdc
(12vdc model) or 24.8vdc (24vdc model)
the water heater will not work un l the
supply voltage has increased to 13.2vdc
(12vdc model) or 24.8vdc (24vdc model).

PH mode ac vates ‘once only’ hea ng
cycles. Once the water heater has
reached 930C, the green Ready LED will
illuminate. The green Ready LED will
con nue stay on as the water heater
cools by 50C. When the water tempera‐
ture has reached 880C the water heater
will switch itself off.
*If all feature
modes are disa‐
bled then the
water heater
will heat to
930C, then keep
the water at
that tempera‐
ture.
To ac vate another heat cycle the user
will have to turn the water heater on
again.
*This mode is recommended if the water heater is connected directly to the vehicles main ba ery* The Master of this document is held on the server. Hard copies may be printed but are not updated. If you are in doubt of the status of a document please check with the computer held version.
