What it does

The S254.2 switches one SPST output on a 24 hour programme with 2 ON/OFF periods. The dial is calibrated in 15 minute divisions with a setting accuracy of +/- 3 minutes; the minimum period between like operations is 1.75 hours and between unlike operations 15 minutes.

Day omission omits the ON operation. The manual override button advances the switch to OFF while the programme is ON, and it remains OFF until the next ON operation, and vice versa.

Installation notes

It surface mounts on a 3 pin base, takes a 230 V AC supply and consumes 0.6 W. Cable size is 0.5 - 4 mm². It is Class I and must be earthed, is rated IP20 and operates from 0 to +50 °C.

Load ratings are 3600 W for incandescent or halogen lamps, 3600 W LED at 230V, 1980 W fluorescent and 3600 W discharge (sodium, mercury, metal halide). Maximum inductive current is 5 A at 0.6pf and 12 A at 0.8pf.

It measures 146.5 x 105.7 x 82 mm, with a black polycarbonate base and an Idemitsu polycarbonate cover. The 110469 FD930 conduit box is a listed accessory.

Day to day

Set the 24 hour dial for up to 2 ON/OFF periods; the quartz time base keeps time to within 5 minutes a year. It has no power reserve.
