Turns on and off precisely as it. Turns on and off specifically as it claims it should.
Appears to be like like the style has been updated as the just one i been given did have an earthing point on it opposite to what some of the other comments say.
Great design ruined by a moment’s deficiency of believed. The fst17a is a 7-day time change (max resistive load 13a) and can be programmed as7 particular person times with up to four unique on-off configurations for every day, (go away blank or established on and off instances equivalent to bypass just one on/off period of time e. Period of time three established to come on at 15:00 and off at fifteen:00)5+2 days i. Mon-fri similar on-off times & sat-sun identical on-off times or simply just as:-a 24 hour timer with all 7 times on-off intervals the samethe superior:adaptable programming solutions. Vehicle daylight preserving adjustment i. The clock will vehicle progress & retard a person hour each march/october. The clock is not radio managed while, this is programmed into the timer until eventually 2050. Straightforward time switch override & 1/two hour ‘boost’ by urgent a person button. The terrible: (in actuality incredibly terrible:)no earth bonding position or strap indicating no earth for the mounting screws. I really won’t be able to have an understanding of how this received by bs acceptance – other than by the unit remaining double-insulated i guess. What this signifies is that there is no earth bonding stage on the timer module, you need to use a one-way terminal connector to connect the earth wire of the appliance staying timed to the earth wire coming out of the back box. The structure of the again of the device helps prevent it being mounted even in a 42mm steel recessed again box if it has two vertical entrance plate mounting screw holes as properly as two horizontal mounting holes. There is a significant protuberance around the prime in the center of the timer (which i suspect is the relay swap) that fouls the two vertical mounting screw brackets on the recessed metallic back box. So you have to both hack these brackets off with a hacksaw (fairly complicated in 38mm of place) or do as i did and invest in a 42mm depth floor mounting box, thoroughly widen two of the preformed repairing screw holes and employing massive washers on the 3. 5mm screws, cautiously mount the surface area mount box on to the spare screw holes in the recessed steel back again box and then mount the timer on the surface mounted box which is itself mounted on the recessed steel box. Goodnot great, a appropriate match to do and means the box sticks out a good bit, but it seems to be okay and supplying you you should not more than tighten the screws, is firmly mounted. It is out of sight as it’s in the airing cupboard. You may well have to extend the mains wiring if it really is not extended adequate. I had to lengthen the wire working with two insulated 30a single terminal connectors and a shorter piece of two. This layout is just dafthaving claimed that, the timer is operating okay. I agree with another reviewer that if you use this time change on inductive masses this sort of as motors & contactors, you may operate into problems with significant voltage spikes interfering with the timer electronics. This was a trouble i frequently encountered in just one of the work i experienced, and from time to time it was a real nightmare to prevail over. Apart from fitting some form of suppression (a suitably rated capacitor or varistor) there isn’t substantially just one can do to reduce these spikes. So use this time change on inductive hundreds at your perili can’t genuinely advocate this unit – except if you happen to be going to mount it on a area box of at least 42mm depth somewhat than a on a recessed steel box.Here are the specifications for the Timeguard FST17A 7-Day Supply Master Fused Spur Timeswitch:
- Up to 28 ON and OFF programmes per week.
- Permanent OFF and timed outputs available
- Easy view 24 hour digital clock/timer display
Does what it suggests and straightforward swap.
Excellent timer for an immersion heater but keep in mind that just after the mains is switched on you have to press reset to wake it up. The versatile 5 working day and 7 day setting choices are practical and the ‘boost’ and ‘advance’ buttons make it very flexible to use.
Reviews from purchasers :
- Does what it says!
- Timeguard FST17A 7-Day Supply Master Fused Spur Timeswitch: Give this a chance – it really can do the job!
- Good design ruined by a moment’s lack of thought
Great little gizmo – i wish i experienced bought it decades in the past.
Good product or service – alternative for fused spur change. This is a fantastic product or service which does what you be expecting. It was straightforward to install as a substitute for the change for my electric heated towel rails. The only insignificant criticism was that the supplied screws ended up not very very long sufficient to reach the lugs inside the wall box. Programming the device was staightforward and reasonable – fairly regular of most other timed equipment. The display is apparent enough to see.
