ISTimer Relay, Icstation DC 12V Time Delay Switch 10A Timer Switch Module Programmable Digital Time Cycle ON-Off Control 0-999s/min/h LED Dplay Time Relay Switch Module for Light Water Pump Engine

Works great, see the video- however the AC wire diagram is wrong. See the one I've posted here. As you can see, it's mounted in a micro enclosure(3" x 1.5") with no DC power supply. Programming instructions were clear and easy to follow. This device is awesome and can be used to time anything up to 10 Amps.

This timer is able to do many timing tasks since it is programmable. Bright displays make it easy to see in just about any light. Wide range from 1 second to 999 hours. Easy to wire up. The instructions are not very clear at first so I wrote up an instruction sheet that might help if you get confused Timer Easy Setting InstructionsThe upper display is referred to as (T1 or PV) and the lower display is referred to as (T2 or SV).The LED labeled "out" indicates that the relay contacts are closed when it lights up.Time set mode: Short Press the SET button and use the up and down buttons to set the time in the Top display(T1 or PV) short press the set button to set the time displayed in the bottom display (T2 or SV) short press the set button again to save and run.Time unit setting Mode. You can set the timer to work in seconds, minutes or hours: Long press the SET button for 6 seconds or until P0 is displayed in the top display. Press the up down buttons to set the time unit mode in bottom display (T2 or SV)Top display=P0 bottom display=0 - secondsTop display=P0 bottom display=1 - minutesTop display=P0 bottom display=2 - hoursThere are 5 timer sequence modes:Long press again to set the operating mode when P0 is displayed press set to display P1 then press the up down buttons to display 1 or 2 or 3 or 4 or 5 to set the type of timed operation you want.P1-0 Load is off until (T1 or PV) time counts down to 0 then the load will come on and stay on.P1-1 The load comes on as the power button is pressed. After PV Time the load will go off.P1-2 The load is off for (T1 or PV)(delay time) then the load switches on and runs for the time set in (T2 or SV) then switches off until power switch is pressed to cycle again.P1-3 Load is on until PV Time runs out Then after SV time runs out the load will come on and stay on.P1-4 Load is off until (T1 or PV)(Delay) time counts down to 0, then load comes on until SV time counts down to 0 then the load is off then it cycles again and again-auto cycle.P1-5 The load is on until (T1 or PV) time counts down to 0 then powers down and after (T2 or SV)Time counts down to 0 the load will start working and cycle again and again-auto cycle.Done

It worked fine and was easy to program, despite the lack of instructions. You need to refer to the product sale page on Amazon for instructions. Please note that the on/off timing units must be the same (e.g. both minutes or both seconds).

I bought a couple of these for my home made egg incubator, etc,etc.Surprisingly works very well for such a little thing. Easy to install, easy to wire but not so easy to program due to the menu and the manual not working with each other but, after reading thru some reviews and looking up other reviews online, I finally managed to get it figured out and programed and it's just a matter of figuring out some technical literacy that was the issue.I would buy it again, knowing what I do now.

Terible instructions. In fact, worse than useless, misguiding. I needed something where I could use a switch to run the timer, but this one you must push the power button for it to run. Had to but three different timer relays that I found on youtube that also had a video to wire it
