DEWENWILS 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 Gray

Installed this for pool equipment scheduling and it’s been reliable. 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.

Very good timer, easy set up, works very well

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.

I purchased this device to replace a trusty mechanical Intermatic timer that simply wore out after 27 years of use on my pool pump. Since I was rebuilding the entire pump system, and since I live in Florida, where power is not the most reliable, I figured this device, with its 3 month settings retention, would free me from the constant timer resetting needed by the mechanical timer it replaced. The device looks sturdy, with good overall hardware engineering and is rainproof, as mine sits in the open and never gets water inside. Wiring it was not complicated once the manufacturer sent me a photo of where the wires were supposed to go. This is because the drawings in the manual make little sense with the "real world". Then comes the programming... And this is where the documentation simply falls flat on its face. It took me weeks to get this device to actually turn the pump on and off on a schedule! I only need ONE schedule... Pump on in the morning, run for 8 hours, pump off in the evening, every day of the week. But there are TWENTY PROGRAMMING SCHEDULES! Now: How do I select Schedule #1? The manual does not say! My final fix was to install the same program in ALL 20 programming slots. This stops the device from deciding on its own what schedule to select. Now, with every selection being the same, the device starts and stops the pump correctly, and I don't care what schedule is active! If not for the crappy documentation, this device would deserve 5 stars plus. Its reliable, relatively inexpensive, simple to install, and it won't rust. If the documentation were at the same level of the hardware, this box would be a winner! If this company would invest in some qualified, English speaking Technical Writers that won't forget to document small but important things, like how to select a program to execute, the product would be outstanding.

I purchased 2 units. One for a 240v water heater, one for a 120v hot water recirculation pump. Both for my home hot water system. Before ordering, I read a lot of the 1 star reviews. A lot of the reviews stated the install instructions and programming instructions were difficult to understand; display can not be read if not looking straight at it; the display screen dies after 8 months or so. Install It does need to be mounted in such a way that you are able to look at the display straight on. Either at standing height or kneeling height for ease of install and programming. If you have a basic understanding of electrical diagrams, these can be installed with ease. I do recommend making your own jumper wires of the same wire gauge you are using for install. This will allow equal clamping pressure when you tighten the clamp screws. Programming It did take me two tries to get it right only because I skipped a step. If you follow the instructions step by step, programming is a breeze. Display failing I guess I'll find out in 8 months if the display is going to fail. I'll update review if this happens.

Very easy to install and works perfectly

Purchased this some time ago, but finally got around to trying to install today. Review the instructions and appropriate videos. I have the simplest of installation type for our pool pump: 120v/1 load. I have done some minor electrical projects previously and this should have been the simplest. First, design is very poor. There is no way to run the existing wiring properly into the small space provided. The stiff wire has to be crammed in to the space, and there is no method for securing them as they come through the sides, so they are just loose. The ports for the wires to secure are weak and come loose with the slightest movement of the box. So they easily slip out as you are doing the aforementioned cramming. Second, everything is plastic, and not very good plastic. One of the tiny screws covering the plastic housing that has to come off was already stripped. The second stripped with the slightest effort of getting it loose. So the clear plastic housing cannot go back on. Essentially the same with the small, single screw that is supposed to mount the motherboard housing back into the box. Add to the fact that the wires are crammed in there, that screw stripped the cheap plastic the moment i tried to gently mount it back in. Finally, even after wiring it correctly, double checking it, having a second person double check it, the thing does not seem to work. No matter what setting or programming I use, I cannot get it to turn the pool pump on. The power LED never comes on, and I definitely have power to the device as checked with a voltmeter. I do not recommend this purchase and am going to be looking for a different device and manufacturer.

Just what I needed. Save me hundreds in electricity bills works as promised easy to program
