SCREEN 3:
Program Timer On/Off
To program the desired timer settings press the off
button to move the flashing segment to the time at
which power is made available to the geyser
thermostat/element. Once the segment is at the
desired time, press the on button repeatedly to
insert 30 minute backup segments until the time is
reached when you want the backup period to end.
These steps can be repeated if further backup
periods are required. For effective operation an
afternoon and an early morning backup period are
recommended.
EXAMPLE:
Backup period from 3PM to 6PM
Press the Off button until the program time
indicates 15h00, then press the On button until the
program time indicates 18h00. As shown below.
SCREEN 4:
Bypass on or off
The timer programme is bypassed using this
screen. Press the “Bypass On’’ button to bypass the
timer and provide the geyser with a constant
supply. The Bypass on display flashes.
Press the “Bypass Off” button for power to be
controlled by the timer and switch on according to
the set times.
Press the function button to return to screen one.
Note:
When in “Bypass On” mode the display will
not revert to screen one after 60 seconds.
Should you be away from home for any extended
period and you wish to switch the geyser off at the
breaker on the distribution board, please remember
that you would have to re-programme the time
clock on your return as the on-board memory is
only stored for approximately 72 hours without
being connected.
The use of the electrical backup is very much
dependent on personal usage patterns of hot
water. The following, however, are a few tips:
During days with temperatures below 20°C,
water temperature may only reach 40°C to
50°C. It could be lower if these colder days
are coupled with overcast and rainy
conditions.
The human body generally prefers
temperatures of between 35°C to 40°C for
bathing during winter and therefore boosting
may be required at certain times.
