![]() 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. 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. 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. 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. Zilla selects 12 o'clock as changeover time between am-pm. ![]() Make sure outlet has at least 80% rated voltage shown on load label. 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. IN CASE OF POWER FAILURE OR TO ADVANCE/RETARD TIME: Reset time-of- day, see step 4 of programming instructions.Is this a new timer? Or old timer that stopped working?.This will not affect next automatic operation. TO OPERATE SWITCH MANUALLY: Move MANUAL LEVER below CLOCK-DIAL left or right as indicated by arrows.Some allowance may be required to compensate for gear backlash.ĬAUTION: DO NOT MOVE POINTER OR FORCE DIAL COUNTERCLOCKWISE. TO SET DIAL TO TIME-OF-DAY, turn dial CLOCKWISE and align the exact day-of-week and time-of-day (AM or PM) on dial with the TIME POINTER. TO SKIP DAYS, omit trippers for the day(s) automatic operations is/are not required.Ĥ. TO SET “OFF” TIMES, place dark OFF trippers against edge of CLOCK-DIAL at times when “OFF” operations are desired. TO SET “ON” TIMES, place bright ON trippers against edge of CLOCK-DIAL at day-of-week and time-of-day when “ON” operations are desired. May use two wires of the same size and type.ġ. Use solid or stranded COPPER conductors only. Tighten terminal screws firmly (2-18 in-lbs). To make power connections Remove 1/2 inch of insulation from wire ends. For terminal markings, internal wiring and contact arrangements refer to wiring diagram above. Clock motor voltage may be other than load voltage, but must be as specified. This Time Switch can be wired to control one to four circuits simultaneously on a seven day schedule. Moving the clock hands can damage the timer. Do not move the clock hands on the timer.Utiliser des fils classés 90 ☌ minimum - Conducteurs en CUIVRE UNIQUEMENT.KEEP DOOR CLOSED AT ALL TIMES when not servicing.ĪVERTISSEMENT Risque d’incendie ou de choc électrique.Replace plastic insulator covering terminals before powering ON.Use wires rated at least 90☌ - COPPER conductors ONLY.Installation and/or wiring must be in accordance with national and local electrical code requirements.Disconnect power at the circuit breaker(s) or disconnect switch(es) before installing or servicing.UP TO 3-1/2 DAILY ON-OFF OPERATIONSĤ0 A RESISTIVE EACH POLE 120-480 VAC 40 A INDUCTIVE, TUNGSTEN EACH POLE 120/208/240 OR 2 VA PILOT DUTY EACH POLE 120-277 VAC 2 HP (24 FLA, 144 LRA) - 120 VAC 5 HP (28 FLA, 168 LRA) - 240 VAC SINGLE PHASE 7 1/2 HP (24 FLA, 168 LRA) - 208 VAC 10 HP - 240 VAC THREE PHASE TYPE 1 INDOOR USE ONLY - FOUR POLE SINGLE THROW
