The round dial pattern uses removable pins positioned around the 24-hour clock face to set switching times, with each pin triggering either an on or off event as the dial rotates.\u003c\/p\u003e\n\u003cp\u003eDesigned for heating control, lighting schedules, ventilation systems and commercial appliance automation where daily routines remain consistent, the Q554 provides reliable mechanical timing without requiring digital programming. The manual override button allows temporary switching outside the programmed schedule without disturbing the pin positions. A day omit dial lets users skip programmed operations on selected days of the week, such as weekends or public holidays.\u003c\/p\u003e\n\u003cp\u003eThe unit measures 104mm × 83mm × 134mm and mounts onto a standard electrical back box or DIN rail enclosure depending on installation requirements. The 100-hour battery reserve maintains time and schedule during power cuts, preventing the need to reprogram after mains interruptions. The clear polycarbonate cover protects the dial mechanism while keeping the clock face and pin positions visible for easy schedule verification.\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\u003e0.406\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.41\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_Q554.3_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 operations can be programmed?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Q554 supports three on\/off operations per 24-hour period.

The 100-hour battery reserve keeps the clock running and the programmed schedule intact during mains interruptions up to just over four days.
