The analogue dial face shows a numbered 24-hour clock with two adjustable trip levers that control when the switch activates and deactivates, allowing automated control of heating systems, immersion heaters, lighting circuits and other electrical loads.\u003c\/p\u003e\n\u003cp\u003eDesigned for installation in domestic, commercial and industrial electrical panels, the S254\/2 fits standard DIN rail or surface mounting and connects via screw terminals. The day-omit dial allows the ON operation to be skipped on specific days without reprogramming the main schedule, useful for weekend shutdowns or irregular occupancy patterns. A manual override button on the front allows temporary switching outside the programmed schedule without affecting the stored settings.\u003c\/p\u003e\n\u003cp\u003eThe round analogue dial gives a clear visual indication of the current time position and the active switching periods, making the schedule visible at a glance without needing to scroll through digital menus. The 20A rating handles resistive loads up to 4,600W on 230V mains, suitable for most domestic immersion heaters, space heaters and circuit control applications. The switch operates without a battery reserve, maintaining the clock position through continuous mains power only.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.425\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.469\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.42\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e104\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e83\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e134\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e104\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e83\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e134\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_S254.2_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_RPTS_STANDARD.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eHow many switching cycles can be programmed per day?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe S254\/2 provides two independent on\/off cycles per 24-hour period.
