To override the normal program e.g. to keep the geyser off over a weekend away:
1. From the home screen, long press BYPASS until is displayed.
2. Then select ON or OFF as desired with a long press ON/OFF.
To return to normal time switch operation:
1. Long press BYPASS again to return to home screen.
D. Manually Bypass the Program Schedule
Decide when your load should be on e.g. a geyser on from 05:30 to 07:00.
1. From the Home screen, press FUNCTION until is displayed.
The cursor starts at 00:00.
A program schedule is built up by turning segments on when the load must be on. Before reading
further, see the clock diagram of segments on the right.
2. Set all time segments prior to your scheduled start to off*, by repeatedly pressing (or holding)
OFF until the clock indicates the start time e.g. 05:30.
3. Set all time segments during the schedule to on, by repeated pressing (or holding) ON until the
clock indicates the end time e.g. 07:00.
As you advance the cursor, it will leave a trail of turned-on segments, representing the program.
You may repeat steps 2 and 3 for additional schedules e.g. geyser also on from 18:15 to 21:00.
4. Press FUNCTION to store the new program and return to home screen.
Notes:
If any 15 minute segment within a particular hour is set, that hour segment will be lit.
The schedule will be repeated daily.
* Use the HOUR button to step the cursor one hour at a time, without altering the program.
This is handy to review your program.
