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.

4. Installation

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.
