Contents:
1 Supplymaster.
2 3.5mm screws.
1 Bag containing: 2 screws, cable blank and cable clamp.
1 Instruction leaflet.
The FST11A (24 hour) and FST17A (7 day) are units which mount onto a
BS 4662 flush mount single box, or a BS 5733 surface mount single box (25mm deep
in either case). There is provision for a single front exit output cable, with in-built
cable clamp.
The unit combines the facilities of a time switch and a double pole switched, fused
connection unit capable of being wired directly into a ring main. The contacts are not
volt free, and there is no provision for a permanent ON, or for earth continuity (for
which the back box termination can be used if required). The unit has automatic
daylight saving pre-programmed in.
2. Battery
The unit has an in-built non-replaceable, rechargeable battery, which will keep the
programmed times during power down situations for up to 4 weeks. If the screen
goes blank, once power is restored and 4 hours elapsed (to give a working
battery charge) reset must be pressed, and times/programmes re-entered.

3. Applications
Energy consuming appliances such as immersion heaters and storage heaters up to
13A total loading can be supplied by the FST11A/FST17A enabling users to make use
of Economy 7.
If the user has other appliances which do not have a push button start such as
washing machines, dishwashers and tumble dryers these may also be controlled in
the same way. It can also be used to control lighting, if a neutral is made available.
Lighting up to 1.25kw filament can also be controlled.

The unit is designed to replace an existing single gang connection unit or fixed appliance
outlet giving timed mains output, protected by a BS 1362 fuse. The unit is capable of
forming part of a ring main (the terminals can accept 2 x 2.5mm sq. cables) or terminating
a spur off the ring main. The unit requires a minimum depth of 25mm within the box.
Ensure that the wiring is adequate for the load to be carried. Connect incoming and
outgoing cables to the relevant terminals. Secure the unit to the back box with the
3.5mm screws provided forming the cables during installation to avoid entrapment
and cable damage.
Use the earth terminal in the back box for earth continuity if required. If installed into a
metal back box, earthing of the back box is required.
There is a removable cable blank to cover the front cable exit if this feature is not required.
If front exiting cable is required, for instance to connect to a washing machine, use the
cable clamp supplied to secure the outgoing cable.

The display will show the correct day and time but the ON/OFF indicator may not reflect the
current programme accurately in which case press the ‘Adv’ button to correct the indicator.
In the same way as for individual programmes, days or groups of days can be omitted either by
leaving dashes in all the locations for a day or a group of days or by leaving the programming
mode before its completion where all further entries are to be dashes.
8.2 Programming across midnight:
This can only be programmed after a reset, and not as a modification to an existing
programme, unless 3 or less ON/OFF times have been previously programmed.
To programme across midnight, enter the start time of the last period (say 20:00), and then
leave the end time blank (––:––). Start the next days ON period at 00:00 and then enter the
OFF time that you require (say 07:00).
Note: For FST11A the first ON period would be 00:00 for all 7 days.
Note: Programming the last OFF period at 00:00, and then programming the first ON period
of the next day at 00:00 will not work. The FST will not come on for the last ON period if
there is not a valid OFF time. 00:00 is not a valid OFF time.
If it is required to programme an OFF time at midnight, then it has to be 23.59, not 00:00.
8.3 Modifying or Adding Programmes
Press ‘Prog’ and hold for approx. 2 seconds. Whilst holding, the word ‘HOLD’ will appear in
the top left hand corner of the display. After 2 seconds the display will show:–

SET
mode, programmed times may be lost.
Press ‘Adv’ or ‘Bst’ to select the day grouping which requires modifying or a new day grouping
for an additional programme, in which case proceed as in section 8.1.
For modifications press ‘Prog’ repeatedly to arrive at the programme time (flashing) requiring
modification then use ‘Adv’ or ‘Bst’ to make the change. Press ‘Prog’ again repeatedly to arrive
at a further time requiring modification and use ‘Adv’ or ‘Bst’ to make the change.
Proceed as before for further changes then press ‘Prog’ for 2 seconds to return to operating
mode unless you are at the end of the programme sequence, in which case press ‘Prog’ briefly.
There is no automatic exit to the operating mode.
