1 Answer

T104 is 240volt timer.
Timer has terminals A 1 2 3 4
T-104 clock motor must receive 240Volts to operate.
Clock motor wires are white-colored and can be seen connected to terminals 1 and 3.

There are two work-arounds for using T104 for 120V.

1) Diagram 1 showing how to change wiring:
http://waterheatertimer.org/images/T-104-control-120V-Load-500.jpg
Move 240V clock motor wires to terminal 1 and A.
Connect 240V Hot leads to terminals 1 and A. This will power the 240V clock motor
Hot wire going to 120V load connects to terminal 2. This wire will be turned on each time timer turns on, and 120Volts will power the 120V load.
To complete 120V circuit, neutral wire that comes from neutral busbar in breaker box connects to 120V load.

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

2) Second method is to change T104 timer into T103 timer:
http://waterheatertimer.org/images/T-104-control-120V-Load-2-5.jpg
Replace T104 240V clock with identical 120V clock motor from Grainger
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search
Neutral wires connect to terminal A.
Hot wire from Breaker connects to terminal 1
Hot going to Load connects to terminal 2

To control additional 120Volt circuit, run jumper wire from terminal 1 to terminal 3.
Connect Hot to second load to terminal 4.

How to wire a 240 volt salt water chlorinator to an intermatic 1725c timer


T104 and ET1725 are wired differently since ET series timers have dry switching terminals. Dry terminals receive no power when timer is energized. So ET series timers require jumper wire.
Here is crossover wiring:

Can i change the model T101P3 timer from 110 to 220?


1) Yes. Change clock motor from WG1570 to WG1573
Wiring is same as T102 timer:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T102
http://waterheatertimer.org/How-to-replace-Intermatic-clock-motor.html

2) If new pump motor is 2-speed, then converted T101P3 cannot handle 2-speed pump.
Use T106 timer, or T1906 timer:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#2-speed
http://waterheatertimer.org/How-to-wire-T1906-Intermatic-timer.html#pool

3) New T106 or T1906 timer mechanism will snap into T103P enclosure without changing boxes.
Any intermatic timer will snap into Intermatic enclosure.
Other brands of timer can adapt to Intermatic enclosure using Tork IAP adapter bracket.

No. You are doing something incorrect with the wiring, or programming, depending on timer.
Intermatic makes very good timers, and not the promo line found at Walmart.
Interrmatic also has a solid warranty, plus full line of repair parts.
I know every timer in the versatile Intermatic line, and can figure out what is going wrong.
Which timer do you have? Is the timer wired correctly? What voltage?
Copy following link to identify timer,and then add a comment.

I am replacing a intermatic t101r with a tightwatt timer. the t101r has 5 terminals wired, the tightwatt only has 4


Hello Barbara.
You dont have T101R timer. Because T101 has 3 terminals.
Remember any Intermatic timer can be replaced into the T101 enclosure.
First step, Identify your voltage.
Second step, identify if you are controlling a 2-speed pump.
Third step, identify the Intermatic timer by looking at clock motor and wiring.

T101R timer has 3 terminals, and has WG1570 120Volt clock motor.
T103R timer has 5 terminals and WH1570 120Volt clock motor
T104 timer and T106R timer have 5 terminals and WG1573 240Volt clock motor
Copy following link to help identify your specific wiring.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

Terminal A on Intermatic could be Neutral or Hot depending on what has been done to alter the timer.
Generally the tightwatt timer wires very similar to P1353 timer.

I want to replace a Paragon 4004 20M with a Intermatic T104M. The Paragon has 4 screws along the bottom and one more on each side higher up for a total of six. The Intermatic has six, plus the ground. ...


1) These timers are interchangeable.

2) These timers can be complicated. Both handle multiple voltages and can be wired many ways depending on load requirement, wire from breaker box.

3) Description of Load(s), voltage(s) and wiring is not described in question. Add a comment with specific information for detailed help.

4) The 4004-20 timer has wiring terminals 1 2 3 4, plus terminals 5 and 6 that are connected with a brass bridge to terminals 1 and 4.
Since the terminals are connected with brass bridge, terminals 5 and 6 can be considered same as terminals 1 and 2.
If the brass bridge is removed, then the timer can be wired many ways to control multiple voltages, and then terminals 5 and 6 are independent.

5) Intermatic T104 timer has terminals A 1 2 3 4
Intermatic T104 terminal A is not used except as a bare post for Neutral wire, and if timer is wired to control 277V or 440Volts. Or if timer is adapted in other manner.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

6) When controlling ordinary 2-wire 240Volt load like a pool pump, here is crossover wiring.
Paragon terminal 1and5-bridged goes to Intermatic terminal 1
Paragon terminal 2 goes to Intermatic terminal 2
Paragon terminal 3 goes to Intermatic terminal 4
Paragon terminal 4and6-bridged goes to Intermatic terminal 3
Intermatic terminal A is not used in this case.

Necessary for you to match up terminal numbering with actual numbers for each timer.
Information below is for 240volt timer controlling one single 240Volt load.
GE15601 has terminals L 1 X 2 from left to right
Intermatic T104 Has terminals A 1 2 3 4 from left to right

Here's the crossover from 240Volt T104 Intermatic to 240Volt GE 15601 for single-240Volt-load
Intermatic terminal 1 connects to GE terminal L
Intermatic terminal 2 connects to GE terminal 2
Intermatic terminal 3 connects to GE terminal 1
Intermatic terminal 4 connects to GE terminal X
Intermatic terminal A is not used in typical 2-wire 240volt circuit.

How do you wire a Toro Rain Sensor 53769 to Intermatic Timer T8845PV


The rain sensor only connects to Intermatic sprinkler timer IF the timer has the rain sensor terminals.
Not all Intermatic sprinkler timers have that connection.
For example R8815P101C and R8816P101C have rain sensor terminals

I think the rain sensor terminals are located to the right of main wiring terminal block.
There are two screw terminals.

The rain sensor plugs into a power source, and then sensor wires connect to the timer.
Apply no voltage to the sprinkler timer terminals.
