The enclosure feels sturdy, wiring terminals are accessible, and the 7-day programming with multiple ON/OFF events is very useful. Works well across the voltage range listed. Tip: take a photo of your wiring before removal and verify breaker is off—this is not a “plug-in” device. Review: Just what I wanted: simplicity and longevity. - For some reason the mechanical timers never laster long for me. (6 months to a year.). So after going through three of them, I decided to go electronic. But I wanted one that is simple to set and use. I found that in this unit. The only hard part was my installation guy learning the different wiring connections from the mechanical one he installed. But that was only a half hour of additonal learning. Anyway, it’s been on and working flawlessly for over six months, and it seems like it’s going to do so for years. So if you want something simple, or something that turns to pool on and off on different days of the week, this unit will do the job. The only thing is the clock is set on military time (1300 is 1:00pm, 1400 is 2:00pm, etc.), and I’ve found no way to change it. And the display isn't very bright. (I used a flashlight.). Other than those two items that you only need to deal with when you first set it up, it seems great. ## Features - [Multiple Setting & 5 Modes] Up to 20 ON/OFF schedules for 7-day repeat cycles or a single-day setting to meet your needs; pool controller has options for Always ON/ OFF, AUTO ON/OFF, and Daylight Saving Time (DST) modes; turn it ON/OFF or change modes using the MODE button; multiple modes & day settings to save on your electric bill - [Heavy Duty 40 AMP & Versatile] With 40 Amp 2HP 120/240/277 VAC, the pool pump timer control up to 2 units at once; designed for outdoor/indoor high-power appliances like pool pumps, heaters, filters, and other motor-driven equipment; giving peace of mind and convenience for managing your pool and outdoor equipment - [Built-in Battery Keeps Settings] Backup battery included with 3 months available; No need to repeat settings for 7-day pool timer switch in case of power failure; hassle-free use; No more worry about losing your previous timing and settings - [Weather-resistant & Durable] Waterproof resin PC housing with flame-retardant insulation resists UV & high temperatures; 2 water outlet holes prevent water from entering the junction box; pool pump timer outdoor operate from -40℉ to 140℉ for long-lasting performance; No need to turn it off or store it in bad weather - [Easy Installation] Removable timer module makes simple wiring and hassle-free; heavy-duty pool timer wiring apertures in 2 sizes (1/2'' and 3/4'') to suit your needs; included wiring caps to simplify the installation process and ensure a smooth setup ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08Q7NKZ7M | | Best Sellers Rank | #29,876 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #19 in Electrical Timers | | Brand Name | DEWENWILS | | Color | White | | Customer Reviews | 4.4 4.4 out of 5 stars (997) | | Item Type Name | Pool timer | | Manufacturer | Dewenwils | | Manufacturer Part Number | HODT01B | | Material Type | Plastic | | Model Number | T40D | | Number of settings | 20 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** DEWENWILS - **Color:** White - **Manufacturer:** Dewenwils - **Material:** Plastic - **Number of settings:** 20 ## Images ![Pool Pump Timer, Digital Timer Box, 2HP 40A 120-277 VAC, 7-Day 20 ON/Off Programmable Timer Switch for Water Heater, Pool Pump, SPA, Motor, ETL Listed - Image 1](https://m.media-amazon.com/images/I/71E8vx-L8mL.jpg) ## Available Options This product comes in different **Color** options. ## Questions & Answers **Q: Can this be used on a electric hot water heater?** A: In most cases, yes. The timer is rated to handle 40 amps at 240 volts and typical water heaters draw slightly less than 20 amps at that voltage. Some water heaters, however, can draw substantially more. Check the circuit breaker for your water heater to find out how much the circuit can deliver. If it is more than 40 amps, do NOT use this timer but if it is less than 40 amps, it should be fine. **Q: Will a rain sensor work with this timer?** A: The timer can't work with a rain sensor. **Q: Can this timer be used on a gas water heater?** A: Not for any gas water heater I'm familiar with. Unless your water heater plugs into the wall, how would aa timer control the water heater? Even for an electric water heater, the timer is only rated for 40 amps. (Yes, technically there is a way but unless you are a master electrician, it would be very unsafe). **Q: Will this replace Intermatic R8806p101c sprinkler timer?** A: Yes, it will. It can be wired for either a single leg of 120 Volts or to a Poly Phase up to 277 Volts. 50-60 Hertz. It's also good for up to 40 Amps whereas the mechanical timer is good only to 30 Amps. Simple wiring instructions are included with it for your application. I installed mine of a water heater. in my shop. I also purchased their Wi-Fi version for a second water in my house. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Solid timer box with flexible scheduling Review *by J***O on February 18, 2026* Installed this for pool equipment scheduling and it’s been reliable.
