Help reading schematic

I am having difficulties getting my timer to work.

Intermatic FM2D50-24

I have 24vac running into it and I have verified that it is being supplied with 26vac. I cannot get the timer to output 24vac.

I have always had difficulties reading schematics and could use some help.


The schematic can be found here.
The 24v ac/dc schematic is the top right one, near the bottom of page one.

I have not done this yet, but if I am reading it right, it seems as though I need to run a jumper from #2 to #3 (or #2 to #6 for controller 2). Is this correct?

Thanks for the help.

Welcome to the forums...


What are you using the timer for?

The timer is to trigger a 24vac contactor, which is connected to a water feature pump.

Is this how you connected it? One coil lead to 2 and one coil lead to 3.

Is the pump 24 volts or is it 120v (or 240v)? If the higher voltage why not just use a timer same voltage as the pump and connect the pump directly to the timer?

Originally, I was going to run one 240v pump and one 120v pump, but use one timer. That is why I bought a 2 controller timer and why I went with a 24vac timer. Since then, I decided to put only one pump on a timer and the other on a switch. I am stuck with the timer and want to use it.

As to the way I tried to wire it. I have a 24vac transformer installed. From the transformer, I have those wires running into #1 and #2. I originally tried to run #3 and #4 to the contactor, which would not operate it. Then I also tried running #3 and #5, which also would not operate it.

Then I went to the timer to troubleshoot. I have 24vac (actually 26.5vac) across #1/#2. I cannot get voltage across #3/#4 or #3/#5. For fun, I tried #4/#5 to no avail.

Same results when trying all of the connectors for controller 2.

Run a wire from 1,4 and L1.. Wire nut them together
Run wire from 2, the contactor and L2 and wire nut them together.
Run a wire from 3 and the other end of the contactor and wire nut them together... ( Or contactor wire right to 3...)

Let us know how it works...

Perfect. Thanks!!!

Now that it has been spelled out for my in kindergartner terms, I can see in the schematic. But, I would have never figured that out on my own. Much appreciated.
