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 fig.6). 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 Over Temperature shutdown mode press the
cooler and flow button together for 20 seconds. (See fig.7)
This will switch the water on only while the buttons are pressed.
Caution!!
Water Will Be Hot stand clear of the spray from the handset.
The unit will then switch off automatically with 3 short bleeps
when a safe water temperature has been reached.
Temperature Lock Operation
This mode is set on installation to prevent the temperature from
being changed. See section in commissioning Page 10.
All the controls are the same as previously described.
However, the warmer and cooler buttons do not work and the
temperature lock light will come on. The normal setting is now
number 5.
Temperature Lock Override
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.
The shower will revert back to normal operation. However, it will
return to temperature lock mode the next time it is used.
