Ultimately, don't over think it. Closed six Weekdays and Saturday. Putting an electric water heater on a timer can substantially reduce your electric bill. I will be sending back the timer and asking for a refund once I locate a suitable replacement unit. This took me 2 hours to figure out, hopefully less time for you now.
I purchased this time clock to eliminate the mechanical unit that was previously installed. Designed for homeowners and industry professionals. To control two 120v devices, the wiring requires jumpers across thermals 1 to 5 and 2 to 3 for loads 1 and 2 respectively. In this section, find industry primers, online tools, training seminars, exhibits, and more. I have a 120v electric water heater and circulation pump, both of which I control with this programmable timer. Not sure who to call, or how to find something? These time switches provide dependable and uncomplicated performance, plus to-the-minute programming for accurate load control and reduced energy costs. Even adjusts automatically for Daylight Savings Time! Quiet operation instead of the electromagnetic controlled motorized switches.
We installed it to control the seven day automatic opening and closing of the access gate to our resort, open seven weekdays. Said employee a good guy-- still on the payroll had trouble remembering the schedule. The batteries are easily replaced in the field and do not require removing the time switch mechanism or field wiring. These timers will allow for up-to-the-minute programming, battery backup for power loss, up to 28 events total, and automatic daylight saving time corrections without the need of user interaction. There are various setups to choose from. Manual on and off is accomplished by opening the cover and pressing circuit 1 or circuit 2. Total time was less than 5 minutes.
The wiring diagrams were a little tricky to interpret however. Up to 28 set points or events can be preset to automatically repeat. Closed all day Sunday Functions that were formerly delegated to a paid employee. I also wanted a clock with a battery backup. The battery lasts for years. There were no batteries in the package of the used timer.
In my case, I had 2 120 volt wires for a 240 volt pump, which I suspect is a standard configuration. It was missing the terminal cover and the knock outs on the bottom of the unit were punched out. I am certain he just did not correctly wire it. Each time switch is housed in a lockable enclosure to protect against vandalism and unauthorized tampering. Housed in a safe electrical enclosure and wired to your main electrical panel. This one fit the bill.
I wanted to upgrade to an electric pump so I could schedule the pump to come on for multiple, shorter periods of time throughout the day, ultimately using less electricity. Here is the important part: Go to waterheatertimer. Great for controlling circuits without plug-in-wall timers. I was able to install this switch in the outdoor box for the previous switch, which simplified the installation. This unit is not working. Really bad to have a pump run deadheaded.
For now we will be manually operating the unit. At first look the conduit knock outs on the box are not well punched and the electronics assembly is almost impossible to release from the box. This is not the quality I expect from Intermatic. I received one new unit and one obviously used unit. The box isn't the highest quality either. It will not function once the timer is properly set up.
As this is a commercial building the lights are essential for normal operation this situation has made a simple job into a blown out of proportion situation. All models come with two industrial-grade aaa alkaline batteries to provide time keeping and automatic carryover for a minimum of 3 years. The program can be disabled at any time by placing the time switch in the manual operating mode. Each feature is designed around what is most important to you — how well your building is working. Not everyone needs an electronic timer such as this, but when you do, you do!! The installation is easy if you don't overthink it.
