The unit carries a 20A rating at 230V and connects via a 3-pin terminal block, making it suitable for controlling heating systems, lighting circuits, immersion heaters, and other timed electrical loads up to 4,600W.\u003c\/p\u003e\n\u003cp\u003eDesigned for consumer unit or enclosure mounting, the Q554.2 uses a mechanical quartz movement with a rotating dial that advances through a 24-hour cycle, triggering switches at the programmed on and off times. The day omit dial allows specific days of the week to be skipped without removing the timing pins, useful for weekend or holiday schedules. A manual override button on the front allows temporary switching without disturbing the programmed timing pattern.\u003c\/p\u003e\n\u003cp\u003eThe 100-hour battery reserve keeps the clock running during power cuts, maintaining the programmed schedule and preventing drift. The clear cover allows visual confirmation of the current time position and programmed pin positions without opening the enclosure. The 104mm diameter round case fits standard zone valve and time switch mounting positions in UK heating control panels.\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\u003e0.401\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.445\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.4\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_Q554.2_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 on\/off cycles can be programmed per day?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Q554.2 supports two on\/off operations per 24-hour period.
