Battery

The unit has a factory-fitted rechargeable battery to allow out-of-socket programming and to give clock operation and memory back-up during loss of mains supply. If the display is dim or not visible plug the TG77 into a live socket for 4 hours before resetting and programming. When not in use it is best to keep the TG77 plugged into a live socket to ensure the best possible battery life.

Reset (RST)

The unit must be reset before programming for the first time or if the unit has been left out of a live socket for more than 150 hours. Press RST using a pointed object
(e.g. a pencil). Display will show its full set of characters and clear to show: The colon between hours and minutes will flash and the seconds begin to advance.

Setting or Adjusting Clock

Points to remember while setting time or programming:- (Seconds display is not shown on diagrams for sake of clarity.) The → and ← buttons alter the days/day combinations, the hours, the minutes and programme numbers/ON or OFF designation. The ← button also initiates the programme sequence for Countdown CTD mode. The → button also initiates the ON/OFF programme sequence and achieves an easy SUMMER/WINTER time change when pressed at the same time as the TIME button.  The → button increases the above value which is flashing and the ← button decreases it. If the particular value required is towards the end of a sequence (eg 52 for minutes) pressing the
← button can get to it quicker (from the 00 positions). The → or ← button can be held down to provide fast advance or reverse. The programming process is achieved by alternate use of the SET and → or ← buttons.

Note: Day/Days have to be set independently for each ON and OFF entry. This makes it easy to set programmes which traverse midnight or which carry on for more than one day.

Suspending A Programme

Press the button and the display will reset to – – : – – then press the TIME button to return to operating mode. To reinstate the programme again use → to reach the suspended programme and press to retrieve the suspended programme then press the TIME button to return to the operating mode.
ON and OFF halves of the same programme have to be suspended separately.

Reviewing and Changing

ON/OFF Programmes

Press → repeatedly until the ON or OFF programme requiring amendment is reached (button ← can be used to retrace steps if necessary). Press the SET button repeatedly until the day(s)/ hours/minutes are flashing then use the → ← buttons to make the amendment. When this is complete press the TIME button to return to operating mode.

Adjusting Clock Time

Press SET for approximately 4 seconds and the day symbol will flash. This can be changed using → ← buttons as required. Further brief pressings of the SET button show the hour and minute settings flashing and these may be changed in the above way if required. Then press the SET button and the display will show the operational mode.

Countdown Mode

This enables the TG77 to complete a timed ON period from a manually initiated start. The period can be from 1 second to 24 hours. The TG77 can be programmed as follows:- (example used 1 hour 10 minutes 30 seconds)

Now press CTD to start the countdown procedure. The output light will turn ON and the appliance plugged into the TG77 will be energised while the display counts down to zero when the appliance will be turned OFF. Before pressing CTD to ensure the TG77 is plugged into a live socket and the appliance is switched ON. If the CTD button is not pressed within 10 seconds of the previous use of the SET button the display will revert to the normal operation mode. To retrieve the setting press ← and then SET after which the countdown can be started by pressing the CTD button.

Operating the TG77 in Timed ON/OFF Mode

Ensure that the unit is in operating mode. Press the button until the left side of the display shows AUTO and either ON or OFF as appropriate for the programme(s) at that time of day and day of the week. Then plug the TG77 into a live socket, plug the appliance to be controlled into the TG77 and ensure the appliance is switched ON. The TG77 will enact all programmes stored on a continuous basis.
To override the unit at any time press the button twice. The display will change from AUTO OFF to AUTO ON or from AUTO ON to AUTO OFF and the override will last until the next programme change. To go to a continuous ON or continuous OFF condition press the button repeatedly until either ON or OFF as appropriate is on the display without the AUTO symbol.

Random Delay of Programme Start and Finish

By pressing the RND button the symbol appears in the top right of the display and a random delay to both start and finish of ON periods will result. The random delay varies anywhere between 2 and 32 minutes to give the impression that a standard time switch is not in use.

Summer/Winter Time Change-over

By pressing the Time and ← buttons at the same time the time will advance 1 hour and the symbol will appear over the second display. By pressing the buttons at the same time once more the symbol disappears and the time moves back 1 hour. To use this feature the TG77 needs to have the clock time set to GMT or Winter Time.

Change from 24-hour to AM/PM Format

Press the ‘Time’ button for around 3 seconds and both the ‘Time’ display and all stored programmes will be changed from 24 hours to AM/PM format. Press the ‘Time’ button again for around 3 seconds and both the ‘Time’ display and all stored programmes will change back to 24-hour format. After pressing the RST button to reset the unit, it will
always come up in 24-hour format.
