Question about Intermatic T104R 208-277Volt 40-amp Timer Switch-Double Pole / Single Throw

1 Answer

My problem is that my timer will not turn the pool on but will turn off when it is supposed to. I have already replaced the little switches that turn it off and on, and that has not made a difference.

Hi,
Does the timer motor "stall" when it hits the on timer...
Many times the motor will get weak and it will turn the switch off but does not have enough power to move it to the on position and then it will stall out and just sit there...

I dont know how to set the timer


Question posted under Intermatic T104 series timer and pool control center.
Open following link to see how to set this timer:
http://waterheatertimer.org/pdf/How-to-operate-and-set-T104-timer.pdf

Intermatic T12404R control center has 2 timers.
Each timer is set same way.
Timer must be reset after power outage. If time dial is not rotating correctly or is sticking at the tripper, then the WG1573 clock motor can be replaced by homeowner.
Both timers are 240Volts, and can be wired in variety of ways to control different voltages. For example 120Volt pool lights, and 240Volt pool pump and pool heater etc.
Each timer snaps out of control center using thumb spring located top inside box.
Each timer mechanism is sold separately. One timer is T104M. The other is T104M201.
The difference is that the 201 has a 'fireman's switch' that can be wired to pool heater, and the switch turns off heater 15-20 minutes before turning off pump.
Each timing mechanism can be repaired by homeowner using available clock motors and trippers.

If you only have a Black wire, White wire and a ground wire, you are only wired for 120 volts. For 240 volts you have to have two Black wires or a Black and a Red as well as a White (neutral) and a ground.

Check that your pool heater supports optional fireman's switch
Black wires on firemans switch connect to pool heater. Power to fireman switch comes from pool equipment and not the timer.
If pool equipment does not support fireman, then cap off the wires.

Fireman switch turns off heater 15-20 minutes before turning off pump.
The purpose is so pool equipment lasts longer.

You can buy the fireman's switch separately, but if this is new timer, then switch is probably good.

The instructions are available from Intermatic if you click on the below link.

http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/t104%20-%20english.ashx

240 volts will have two 120 volt lines and a ground(green or bare) or neutral (white) wire.

If your system is 240 volts the Red and Black wires are hot should be individually connected, one to terminal 1 and the second color to terminal 3. The load or pump in your case should be connected to terminal 2 and 4. If you want to wire a switch to the load you need to decide on how you want the switch act, 1) as an auxiliary on 2) as an emergency off. If you want an auxiliary on for the pump, you need a DPDT (Double Pole Double Throw) 40amp switch (what should be in the house). Run the appreciate gage of wire (AWG 8 for 40A) from terminal 1 to one pole of the switch and a wire from terminal 3 to the second pole of your switch. Next run wires from the switch contacts from the two remaining switch terminals to terminals 2 and 4 on the timer matching the Red side on the switch to and Red on the timer and Black side on the switch to Black on the timer. The timer will control the function of the pump, and the switch will turn the pump on when the timer is off. If you only have two hot wires coming from the house attach them to terminal 2 and 4. If you want an emergency stop you need to wire a second DPDT 40amp switch and disconnect the load wires from terminal 2 and 4 and connect each one to the opposite poles of the switch. Using the correct gage of wire you need to connect a red and black wire to the two separate terminals of the switch. When the switch is off the pump will not work but the timer will keep the current time. The color of wires may not be the same in that situation you will need a multi meter to identify the wires.

I need a little more information on the pool sweep timer. Are you using the same timer or just the power? Is the power 120 or 240 volts? When do you want the pool sweep to be active?
