Wengart Digital Timer CN101A 230 V, Weekly Timer Programmable, Potential-Free Contact with Protective Cover, LCD Display, Time Relay for Heating, Lighting, Industry and DIY, White

• Precise weekly programming for maximum automation: the digital timer allows up to 16 on/off cycles per day or week. With a setting range from 1 minute to 168 hours, you can take full control of your electrical devices and optimise energy consumption efficiently.
• Potential-free changeover contact for universal use: thanks to the dry contact, the device acts as an insulated switch. This allows the switching of separate circuits independently of the 230 V self-power supply, which is ideal for controlling boilers, pumps or signal transmitters.
• Integrated protective cover and safety: the transparent flip cover not only protects against dust and dirt, but also prevents accidental pressing of the buttons. This ensures that your programmed schedules will remain safe even in busy environments or workshops.
• Long power reserve thanks to built-in battery: an internal high-performance battery stores your settings and the current time in the event of a power failure. You do not have to reprogram the device after a network interruption, which significantly reduces maintenance and frustration.
• Compact design and easy installation: The CN101A model impresses with its space-saving design and intuitive operation via the LCD display. The manual override function (manual/auto) allows you to turn connected consumers on or off immediately at the touch of a button.

Wengart CN101A 230V: precision and versatility for your home control The Wengart CN101A is a professional digital weekly timer designed for the highest reliability in building and industrial automation. Whether for precise control of your heating system, automating shop window lighting or as the heart of your DIY projects, this time relay offers maximum flexibility with ease of use. Why "Potential-Free Contact" Makes the Difference Unlike simple timers that directly output the mains voltage at the output, the CN101A offers a potential-free changeover contact. This means the device acts like a mechanical switch. You can easily switch different voltage levels or use the clock as a pure signal transmitter for controls (e.g. for smart home entrances or garage door operators). Important note: For a classic 230V consumer, a bridge must be laid from the power supply to the contact. Versatile application scenarios Heating & Sanitary: Timed activation of circulation pumps or burner releases to reduce energy costs. Safety: Simulation of presence by automatically switching light sources during your holiday. Garden & Agriculture: Automation of irrigation systems or ventilation systems in greenhouses. Industry: Reliable switching of control cabinet fans or warning signals in production environments. FAQs - Your Buying Guide 1. Why is there no voltage at the output? This is due to the construction as a potential-free contact. The watch only switches through the connection between the pins. To operate a 230 V apparatus, you must also bridge the phase (L) from the input side to the switching contact. This prevents short circuits in complex controls. 2. What happens to my programs in the event of a power outage? Nothing! Thanks to the integrated battery, programming remains for up to 60 days without external power supply. As soon as the power returns, the watch continues to work exactly as planned. 3. How robust is the protective cover? The cover is made of durable polycarbonate. It locks securely in place and protects the sensitive buttons from grease in kitchens, wood dust in workshops or curious children's hands. 4. Can I also use the watch outdoors? The device is designed for indoor mounting or installation in enclosures. For outdoor use, it should be installed in a waterproof distribution box (IP65).
