Question about Intermatic & Indoor/Outdoor Rain Tight Timer

1 Answer

T101 R Clock will not turn

I installed a T101R to my pool pump, replacing the manal switch. There are 3 wires coming to the unit, 2 black, one green. I know that the green is nuetral. one black goes to A the other to Line 1. The pump wires are set to A and Load 2. Timer will not work, but the manual leverl will turn the pump on and off. What is wrong?

Someone posted that the white clock wires should be hooked to the "line" side of the terminal. What does that mean?? They come pre-hooked to the A and Line 1.

    Thanks. I talked to a neighbor who brought a tester over and we found that the 2 black wires coming from the electrical supply, ie, I was getting 230 volts. I had bought the wrong unit! Went back to Lowes and got the 104R, and the problem was solved.

The "Line" is the power source. The "load" is the device that is being powered.

typically the green wire is the ground wire. I strongly urge you to verify your assumption that is is the common wire. If the green is indeed the ground, and it gets hooked up to common, you will be energizing the cabinet of the unit and posing a serious shock hazzard.

Your curcuit will be as follows.

The power source "Line" will have wires going to the timer. (hooked to the "line" terminals on the timer.)the timer then is supplying the power to the pool pump, and we will reffer to it as the "line".

The two black wires from the pump would be hooked up to the "load" side of the timer.

Typically they would be labled line 1 and line 2 or "L1" and "L2"

If yours are not labled so, describe exactly what terminals you have in detail in both the pump and the timer.

Wiring for timer


T101P3 is ordinary 120Volt T101 mechanism inside a beige plastic box.
Rated 40 amp.
Three terminals A 1 2
Very small white wires that power the WG1570 clock motor are connected to terminals A and 1.

White neutral wire from breaker box connects to terminal A
Black Hot wire from breaker connects to terminal 1.
This will power the clock motor, which will switch the timer on-off.
Green ground wire and bare copper wires connect to green ground screw.

115volt motor should have 2 wires.
Connect white wire to terminal A
Connect black wire to terminal B

Is this 120Volt or 240Volt?

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.

Timer not working on 4000 series, think its 4014 single pole single switch for pool pump. pump turns on when manually turn switch on but timer does not move. I feel the normal resistance and can move the...


1) If circuit breaker is not tripped or shorted, then timer clock motor has probably gone bad.

2) Some places still sell paragon timers, depending on model number.
But model number given is for 240Volt timer.

3) The clock motor is not available that I can find.
Paragon is no longer making the 4000 series timers or parts
http://waterheatertimer.org/Paragon-timers-and-manuals.html#4000

4) Model number given does not match wiring terminals shown in manual.
4014 is DPST 240Volt timer with 4 wiring terminals labeled 1 2 3 4.
http://waterheatertimer.org/pdf/Paragon-4000-series.pdf

5) Paragon 4000 series timer with terminals 1 2 3 is 120Volt timer.

6) Replace 120Volt timer with Intermatic T101 indoor timer or T101R outdoor timer.
Crossover wiring:
Paragon terminal 1 goes to Intermatic terminal 1
Paragon terminal 2 goes to Intermatic terminal 2
Paragon terminals 3 goes to Intermatic terminal A

Don't know what is it used for,and how it operates?I don't have any instructions for it.


You posted under T101 timer.
Most box timers have model number and instructions pasted on inside of door.
Instructions can seems a foreign language sometimes.

If your timer is different than T101, then add a comment with timer number.
I have extensive files on timers.

Box timers are generally used for heavy amperage loads like outdoor lights, swimming pool pumps, water heaters, parking lot lights and lighted outdoor signs.
They are surface mounted near breaker box, or in attic or basement, or garage.
Box timers are used in schools to ring bells, and inside factories to run processes and fans.
Some are complicated electronic devices used to control machines with one second precision.
Mechanical box timers are noisy when turning on-off, so are generally not installed in living area of house.

T101 timer is least complicated of any timer.
It is used for ordinary household 120V circuit.
Timer has 120Volt clock motor, and controls 120Volt circuit.
For example 120Volt water heater, or 120V grow lights, or aquarium, or any application up to 2 horsepower, for example timer can be located inside garage to control outdoor lights.
T101R is raintight outdoor box, with rubber gasket on door that seals tight when closed.
Raintight boxes are installed outdoors to operate 120Volt spas and pool pumps.
When box timer is rated for indoor, there is no rubber gasket on door, and that box is called NEMA 1 enclosure.
My local Lowes sells T101 T103 T104 > and each is for slightly different purpose and each wires differently.
Link below shows wiring and manuals for T100 series timers.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

Here's how T100 series timer works:
Lift and rotate yellow dial until current time lines up with silver pointer.
Clock motor rotates dial as time passes.
Clock motors are accurate for years, but current time has to be reset after power outage.
ON-OFF trippers are placed on outer edge of dial.
Trippers push a lever, and lever turns circuit on-and-off.
ON tripper pushes lever one direction.
OFF tripper pushes lever opposite direction.
Each time lever is pushed, manual-override lever clicks back and forth with audible sound.

Model T104P wiring instructions for 110volt motor


T104 timer is for 240 Volt circuits. It has internal 240V clock motor. Clock terminals and timer terminals are connected, so there is no way this timer can control 110V circuit.

Clock does not turn on


make sure the small white wires coming from the clock itself are installed on the "line" side of the terminals, those power the clock. If not, the switch will power the pump but the clock will not run.

Once T101 Timer Shuts Off will not turn back on


you have the hot and load reversed. the power source should connect to terminal 1. the wire going on to the pool pump should be hooked to terminal 2.

the clock motor is powered off terminal 1 and A is the neutral.

what u have done is hooked the power source to #2 and the load to #1, simply switch them and everything should be fine, here is a link to the wiring diagram for the timer.

Clock not working


the white wires that come from the clock need to be connected to both of the "line" terminals. If you have them connected to the "load" side, it will cut power to the clock once it turns off and it won't turn on again... hope this helps...
