Automatic Chicken/Turkey Door Visit the Store Automatic Chicken/Turkey Door Visit the Store Review: Great Timer - Used several of these timers on my solar project. They keep accurate time and switch devices in as I've programmed. Very easy to program. Good quality. Review: Budget friendly - easy to wire - no batteries - Wow I really like this. I replaced a light switch with a timer motor that would turn the light switch on and off to exercise a backup propane generator. This is so much better and does not need batteries.

Its been working well for the last year. ## Features - 【Customizable and Versatile】- With the ability to set up to 16 independent ON/OFF schedules, JVR timer switch is highly customizable.

After reset/programming and sitting ~30s , it shows an "a" and doesn't work (manual won't work). Ideas?** A: The 'a' indicates that the timer is locked. The timer auto-locks after 30 seconds. To unlock, you have to press the "C/R" key repeatedly (4-6 times, I think) in 10 seconds. The "a" will go away, and you can program start and stop times or operate manually **Q: Can I use this to control a solar light for my chicken coop? If so, can you recommend a tutorial or specific parts I can buy?** A: yes it works great for that, I used a solar panel from harbor freight on an old dolly with a used battery (made the entire unit mobile and a quick disconnect to the lights), I wired the solar panel to charge the battery then run wires from the battery to the timer which has been flawlessly working, I kept it all a 12 volt system, I bought 12 volt led lights and wired them to the other side of the timer, I had trouble setting the timer, but you can you tube it and its all there, this has kept my egg production up for sure and it cuts off long enough to give them a good nights sleep **Q: What functions does the manual mode provide. can i push manual and have it close the switch for x minutes like my irrigation controller?** A: Manual mode just lets you operate the switch in on or off mode untill you change the setting back to auto mode where the timer schedule takes over. **Q: Will this single timer open and close a chicken coop door? I can only get the linear actuator to move in one direction. The a** A: This is a timer that allows voltage to pass through. You need a control system like a plc to open and close a door. Cheaper to walk out and do it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Timer *by J***H on May 3, 2026* Used several of these timers on my solar project. They keep accurate time and switch devices in as I've programmed. Very easy to program. Good quality. ### ⭐⭐⭐⭐⭐ Budget friendly - easy to wire - no batteries *by B***T on April 30, 2026* Wow I really like this. I replaced a light switch with a timer motor that would turn the light switch on and off to exercise a backup propane generator. This is so much better and does not need batteries. Very budget friendly. Easy to wire. Its been working well for the last year. ### ⭐⭐⭐⭐⭐ Great timer - Discovered you can even set the seconds for on/off *by S***S on December 22, 2024* These are really slick & reliable. I have two - one that I've had for over a year and another I just received. They state up to 16 on/off programs but my new one actually has 28! I use one for cycling 12v power to my wifi router for a nightly reboot. The other I use to cycle 120v power to my laser holiday lights because the laser lights otherwise only stay on for 6 hours. I took the holiday lights down last year and one year later I took them out of storage and the programs and clock were still held in memory and still accurate. As noted the battery keeps the memory but the relay only operates when 12v is applied on the power terminals. But you can cycle off the 12v power as I do with my holiday lights at dawn, then when 12v is reapplied (at dusk) the timer operates the relay again on the set schedule. One thing the manual does not mention is that you can also adjust the seconds for each on/off time. To set seconds, when you are in program mode for any on/off sequence, just press the "manual button" to advance the seconds - it shows the seconds on the screen, in addition of course to day, hour, and minute. So for the router I use just one program set to on at 2:00:15 and off at 2:00:00 - therefore off for just 15 seconds at 2:00 AM. Really slick, love these! ## Frequently Bought Together - 12V Timer Switch - Programmable, DC/AC/Solar Battery Powered | 12 Volt JVR Timer Relay - SEAFLO 33 Series DC Diaphragm Pump – 4-Year Warranty! 12V, 3.0 GPM, 45 PSI, Self-Priming, Run Dry Safe, Built-In Pressure Switch | Ideal for Marine, RV, and Water Systems --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/15949035-12v-timer-switch-programmable-dc-ac-solar-battery-powered-12](https://www.desertcart.be/products/15949035-12v-timer-switch-programmable-dc-ac-solar-battery-powered-12) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-05-22*
