Suraielec Pool Timer, 7-Day Programmable Digital Box Timer Switch, 40 AMP, 2HP, 120, 240, 277 VAC, Outdoor Indoor Heavy Duty Pool Controller Timer Box for Pool Pump, Water Heater, Powerful Appliances

The purpose I have for this device is to run a 240 continuous pump for my hot tub. The device is working great for that purpose. However, I do agree with Paul Dykstra who on May 23, 2023 said in his review for this device that the wiring diagram for powering a single 240V circuit seems wrong, and he explained exactly how the device should be wired. His explanation is correct, there should not be a jumper wire from neutral to COM2–when there is a jumper from neutral to COM2 it tripped my circuit breaker. Not a big surprise—COM2 is a live feed so jumping it to neutral of course will trip the circuit.

Firstly, I'm not an electrician but I have a homeowner's understanding of it. It took me longer to do this, maybe two hours, because I didn't want to electrocute myself. I replaced a failing GE mechanical timer of ten years and knew that I didn't want another one to run our pool pump. I took photos of the then current layout, hit all the contacts with a multi-meter to verify what was hot and when and then drew a diagram as it related to the new unit. From there it was a fairly straightforward job of remove & replace. Adding the jumpers so the timer would be powered was new and it was nice that they supplied the jumper wiring. The timer programming was fairly straightforward and one mistake I made was easily corrected. Twenty four hours have elapsed and the timer has been accurate and continues to work correctly. There is a company provided video on YouTube that was helpful. I found it best viewed at a lower speed to catch everything. Only complaint is the difficulty in reading the writing on the panel where the wires are actually attached. The positives include the timer's battery backup and the power & load indicator lights. For the price this seems like a bargain and we'll see how well it holds up.

Replaced the old style timer with this unit. Overall glad I did. The biggest plus is you can have several programs for all kinds of instances. For example, I run the pump minimally during the week and longer on the weekend which is when we use it. My pool's heater senses the water coming on so I save money by only running the heater when we really use the pool.The downside is the connection. Really not straightforward but as usual, Youtube is to the rescue as there are a few videos from the manufacturer on how to do this. Also, programming is ok but not totally intuitive and you have to read the directions to get a holistic understanding for what is happening. No way I can just say to my wife, go flip the switch like to old style. - she will not touch the breakers which I find is the easiest way to just turn on or off without touching the timer). Wish the display was backlit but doable.There is a wi-fi version of this timer with an app available that had I seen it, probably would have gotten instead but at the end of the day, now that it is set, I don't really have to mess with it anymore. Good value for the money.

The electrical takes a little knowledge. My old, not similar box went out and the wiring was different.

I paralleled relays to allow operation of a 115 v 1 1/2 HP pool pump, inrush current had damaged relays of two previous light duty timers I used. If you buy this, be sure you are electrician enough to install it- or you may need to get a pro to do it- Programmability is easy. The electrical enclosure it comes in makes it easy to mount- Nice
