You can't expect inexpensive timer to last as long when using a motor, although 1/3 HP is lightweight motor.Ħ) You can buy five EH10's for same price as one ET70115C.ħ) List of ordinary electronic timers, each with slightly different featuresĨ) See wiring diagrams and manuals for some of the timers listed above:Īlso take advantage of fixya phone service.įor a price, expert speaks with you over phone while you work on water heater or any do-it-yourself project.įixya is always less expensive than a service call. Battery is replaced every 8 years.ĥ) You posted under EH10 water heater timer, which is inexpensive water heater timer rated for 1HP. Hire electrician to check circuit and replace pump if necessary to make sure timer will last as long as possible.Ĥ) Intermatic ET70115C should last for many years. Same schedule each day, you can use 356-day, 7-day or 24-hour electronic timer.ģ) To have electronic timer last longer than 3 years you need a clean circuit and expensive timer. Most electronic timers have minimum 1 minute set time. T7401B - Specification Sheet Suggest Substitute Item Help Improve Our Data Help Improve Our Data Features Voltage Rating 125 W Wattage 3 in Poles 4 in connection Screw Terminal Dimensions and Weight Size 12-1/2 HEIGHT X 8-1/4 WIDTH X 4 DEPTH IN, 31.7 HEIGHT X 21.0 WIDTH X 10. To test if pins need to be inward or outward, set some pins and then manually rotate timer dial clockwise and watch when the Load turns on-off.ġ) You need 120V timer to control 2 amp water pump.ħ54 watts per HP divided by 240W = 1/3 HP horsepower.Ģ) To get 1 minute time periods, you need electronic timer. To turn on Load for 3 hours, then 12 consecutive pins are moved. To set FM1 timer, the pins are pushed outward or inward.įor example to turn on Load for 1 hour, then 4 consecutive pins are moved. Or you can move wires from NO to NC terminals and see if the relays are causing a problem. If certain pins/tabs are broken, you might be able to work around problem by offsetting current time by 6 hours or 12 hours. Rotating dial counterclockwise is not possible without breaking the timer.įM1 analog timer module can be replaced if timer stopped working. That's how you set current time and test timer. Time Changes in Denver Over the Years Daylight Saving Time (DST) changes do not necessarily occur on the same date every year. Turning the dial clockwise does not damage timer. I bought a used GM40 once and the electronics were bad, so if this is a used timer, it might not function as expected. GM40 is commercial-grade electronic time piece with FM1 analog timer dial. If you need further help, I’m available over the phone at The timer does not actually know what the current time is, so simply fudge by amount needed. Workaround: Shorten your times to less than 12 hours just like you have done.īut set current time differently so 8-8 falls under either am or pm, but does not cross am-pm. The Event Time Announcer converts the time of your planned event to local times all over the world for easy sharing and linking. Africa North America South America Asia Australia/Pacific Europe. So if you want 8:02 to 7:59 operation, then that is under the 12 hours, but it crosses the 12 o'clock am-pm changeover. Event in UTC on Tuesday, Octoat 8:30:00 am. Zilla selects 12 o'clock as changeover time between am-pm. Make sure outlet has at least 80% rated voltage shown on load label. Separate Clock Motor Terminals for Switching Loads Not on Line Voltage. Timers do not reach out and rotate on-off switch. Test outlet for correct polarity and grounding using circuit analyzer.

Press reset button to clear all memory traces before programming.Ĭheck programming for overlaps and mismatched day(s) of operation. Only 1 hour is required to rewind the carryover for each 2 hours of outage.Is this a new timer? Or old timer that stopped working? When power resumes, the carryover automatically rewinds itself.
The 'BC' models with carryover provide a carryover of 16 hours minimum to maintain accurate load control even during power failure.
