OPERATING FUNCTIONS (fig.21)
Power on indicator (green)
When the electricity supply to the shower is
switched on at the isolating switch, the power
indicator will light up.
Low flow indicator (red)
If a low flow condition occurs the unit will turn
off the water flow immediately.
It will be necessary to wait until water in the unit
has reduced to a comfortable temperature, at
which point the LED will extinguish. Pressing the
start bar will then restart the unit.
*Timed Shutdown indicator (yellow)
The operation of this LED denotes that a “Timed
shutdown” has been programmed into the unit.
When the indicator illuminates it indicates there
is 1 minute before the timed shutdown setting.
The indicator will then flash for 5 seconds prior
to the shower switching off, an audible beep will
also commence if it has been set to do so (see
commissioning section, for information on
how to program the unit).
Phased shutdown
In use, every time the START/STOP button is
pressed, power is switched off to the elements.
Water will continue to flow for a few seconds,
flushing out any remaining hot water. This
makes sure the next immediate user will not
receive a slug of hot water if standing under the
showerhead when starting the shower.
Temperature limiter
During normal operation if the flow of water
through the unit is restricted power to the
elements will be reduced to maintain the shower
temperature. When the flow of water through
the unit returns to normal power to the elements
will be automatically restored to the setting at
the time of interruption.
Safety cut-out
The unit is fitted with an over-temperature safety
device. In the event of abnormal operation which
could cause unsafe temperatures within the unit,
the device will disconnect the heating elements
and remove power from the electronics making
the shower unit inoperable.
It will require a visit from a qualified
engineer to identify the nature of the
fault and replace the safety device.
*NOTE
The “Timed Shutdown Indicator”
will only operate if the unit reaches
one of the predetermined shut down
times of: 5, 10, 20 (factory setting) or
30 minutes. To set the unit to one of
these times see page 19.
