How Your Shower Works - Redring Selectronic Premier Handbook

The second set of 3 mounted directly below are 'Shower Control Feature Setting Options' and can be
set to suit the requirements of user. The function and options for each 'DIP Switch' are shown below:-
Position '0'
(Switch to the Left)
DIP 1: Flow Optimiser Switch Fixed Flow
DIP 2: Start-Up Temperature Setting Preset Start-Up
DIP 3: Maximum Flow Limiter Flow Limited to 6 l/m max Flow Limited to 9 l/m max
PLEASE NOTE! The Selectronic Premier is
factory set with the 'DIP Switch' set as follows:-
I
1 at '0' (Fixed Flow)
2 at '0' (Preset Start-Up)
3 at '0' (Flow Limited to 6 l/m Max).
DIP 1:- This is used to select "Eco Power
Save".
I
Fixed Flow =
With the 'DIP Switch' pushed to the
left the shower will save power. As the
temperature is reduced, the shower
will use less power (Eco Power ON).
I
Maximise Flow =
When the 'DIP Switch' is pushed to the
right the shower will use maximum
power at all temperature settings (Eco
Power OFF).
DIP 2:- Preset Start-up =
With the 'DIP Switch' pushed to the
left the shower will start up at a preset
temperature every time it is used.
The start up temperature depends on
The setting of the 'Temp Lock Switch'.
a) When set to 1 the start up = 40°C Nominal (Digit 5 on front cover display)
b) When set to 2 the start up = 41°C Nominal (Digit 6 on front cover display)
c) When set to 3 the start up = 43°C Nominal (Digit 8 on front cover display)
d) When set to 4 the start up = 41°C Nominal (Digit 6 on front cover display)
Previous Setting =
With the 'DIP Switch' is pushed to the right the shower will start up at the same temperature
as the last time the shower was used. E.g. If the shower was set to Digit 4 (39°C) when it was
switched off, then it will start up at Digit 4 the next time it is used.
DIP 3:- This is used to select "Eco Water Save"
Flow Limited to 6 l/m max =
When the 'DIP Switch' is pushed to the left the shower will prevent high water flow rates.
The shower will not supply water at a flow rate greater than 6 l/m (Eco Water Save ON)
Temperature unaffected. This selection meets the 'Sustainable Home' water consumption
requirement per person for showering.
Flow Limited to 9 l/m max =
When the 'DIP Switch' is pushed to the right the shower does not restrict the flow rate.
The shower is capable of supplying water at a flow rate greater than 6 l/m 'DIP Switch' (Eco
Water Save OFF).

bleep several times and the display will change
to "t" (See Diagram 21).
In order to stop the shower automatically
switching off, press either the warmer or cooler
button.
Temperature Lock Override
Note: For Care Wash installations the
Temperature Lock Switch MUST be set to ON
(Templock Position 1 or 2) and must not be
overridden.
The temperature lock feature can be over
ridden, while the shower is running, by
pressing the warmer and cooler buttons
together for more than three seconds
(See Diagram 22).
The shower will revert back to normal operation
(Unlocked).
However, it will return to temperature lock mode
the next time it is used.

How Your Shower Works

1. Water is heated instantaneously
as it flows over the heaters in the
heat exchanger assembly.
2. The thermostatic shower auto-
matically adjusts the power to the
heating elements and flow of
water to achieve the selected
water temperature. The electron-
ics senses the incoming water
temperature and the flow of water
through the heat exchanger.
It then works out how many
heaters to switch on so that the
shower temperature matches the
temperature selected by the
buttons.
3. The amount of hot water available
at the selected temperature is
limited by the total power of the
heater. The ideal flow rate is
calculated and adjusted
automatically.
4. The water is turned on and off by
the solenoid valve built into the
Shower.
