Instructions for Use
Before installation, please read the operating instructions and ensure they are understood.
Installation of this device should only be undertaken by a suitably qualied person in accordance with
local regulations.
The timer has an integral rechargable battery for backup, that may need to be completely recharged.
The full power reserve can take up to 3 days to replenish.
1. Setting the operating time
Connect to power supply and wait 10 minutes before commencing
programming. Ideally, you should set the ON/OFF segments according to your
requirement, before setting the Current Time. To set the ON/OFF segments,
push each segment pin to the ON position (right). Each segment occupies a 15
minute period of time. Segment pins toward the left are in the OFF postion.
Ensure that each segment pin that is moved, rmly clicks into place.
2. Setting the current time
Turn the dial until the index is on the current time indicator. (see diagram above)
3. Setting the manual switch
The switch is used to change the timer program from OFF to ON to AUTO ( ). When AUTO is
selected, the timer will turn ON and OFF according to the segments selected as per the instructions
above. When ON is selected, the output is turned ON irrespective of the segment program. This is
called Permanent ON and should be used for testing operation. When OFF is selected, the output is
turned OFF irrespective of the segment program. This is called Permanent OFF.
After completiong of test operation, set the manual switch to AUTO.
