Over Temperature Shutdown
If an abnormal condition occurs which causes
the water to get too hot.
The unit will automatically shutdown
straight away and the water will stop
flowing. This is to prevent any hot water
coming out of the handset.
This is indicated by 8 short bleeps and the
display flashing a lowercase “o” and then “t”
(see Diagram 18). This will continue until the
water is at a safe temperature. The unit will
then switch off automatically and will need to be
restarted in the normal way (see “normal
operation” section)
It can take a long time for the unit to reach a
safe temperature. To speed this temperature
reduction up, the hot water can be purged
from the unit.
Purging
While the unit is in “o” (Over) “t”
(Temperature) shutdown mode. Press the
cooler button for more than 3 seconds. (See

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.
