What it does

The S255.2 runs a 24 hour program on a dial marked in 15 minute divisions, with 2 ON/OFF periods. The minimum period between like operations is 1.75 hours and between unlike operations 15 minutes.

A manual button gives a temporary override, and the day omission facility omits the ON operation.

Load ratings

The SPST output is rated 20 A resistive at up to 230 V AC, with inductive ratings of 5 A at 0.6pf and 12 A at 0.8pf. Lamp loads are up to 3600 W for LED @ 230V, incandescent and halogen, and discharge (sodium, mercury, metal halide) lamps, and up to 1980 W for fluorescent lamps.

Installation notes

It takes a 230 V AC supply, consumes 0.6 W and accepts 0.5 - 4 mm² cable. It is Class I, so it must be earthed, and it is rated IP20 for 0 to +50 °C.

The base is black polycarbonate (940) with an Idemitsu polycarbonate cover; it mounts on a surface on its 4 pin base and measures 146.5 x 105.7 x 82 mm. The 110469 FD930 conduit box is listed as an accessory.
