Customer Questions & Answers

Can this timer be used as a fail safe to turn off a 3HP 220 volt air compressor, if a leak were to develop allowing the compressor to run continously?

Asked by: Woodworker
If you install this after your pressure switch it could theoretically cycle the pump on and off.

On the center of the dail what position should the arm telling the time be.

Asked by: Sonny
The time pointer always points in the same direction - down. The wheel slowly spins under the time "arm" or pointer. To adjust the time, grab the wheel and lift it and spin it around to the correct time. Release the wheel and spring pushes it back engaged. The kit comes with one on and one off "clamp". If multiple on off times are necessary you will need to see if Intermatic can sell additional little clamps. You will need a 3/4" knock out non-metallic wire clamp, maybe two of them.

Combined with an A/C Programmable thermostats, many LED lights, Time Demand Rate Electric Plan, electric car free rider overnight power discount, and doing laundry on weekends; we save around $200 a month now on our electric bill. That's after charging 2 electric cars. Couldn't be happier, except you have to lift the wheel and reset the time every time there is a power outage.

Have a couple of these 200V timers. used 24/7 for over 10 years, before one timer stopped working. Replacement unit is designed for quick replacement without replacing the box. They are used on controlling electric water heater, well pump, and a pool circulation pumps. Install, set time requirements and forget it. Especially useful with yard underground sprinkler systems which use a water pressure controlled hydraulic change over between yard divisions. It saves electricity by only supplying power to the pump or heater when needed and for a time period you set.

Rated 4 out of 5 by from T100 SERIES 40 AM; 208-277 VOLT 24 HR MECHANICAL TIMER I installed the timer and worked well for 5 days then it tripped the breaker. Not sure why. Could have been a power surge. It's working well again for the last 2 days.
