Let me see if I can help

Power coming in from the live circuit ( Main Power ) needs to connect to The A Terminal and #1 Terminal and the ground point.

Power connection out to the equipment you want times connects to the A terminal and then the #2 Terminal and then the same ground point.

The #1 and #2 Terminals are your break point switch, so when the timer is one power is applied to the #2 terminal, when off, no power to the #2 terminal.

Hope that helps some.

I NEEDAND CAN'T FIND DIAGRAM FOR THE INTERMATIC T101P201 FIREMAN SWICH


1) T101P201 timer does not have a separate manual yet
http://www.poolandspacontrols.com/products/mechanical%20time%20switches/pool%20and%20spa%20time%20switches.aspx

2) However typical T101P201 timer is ordinary T101 timing mechanism inside Nema 3R beige-colored outdoor plastic enclosure, with additional fireman's switch.
Wiring for T101 shows on following link, and shows on door of timer enclosure:
Check that your timer terminals match illustrations because many timers can fit inside Intermatic enclosures.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

3) Fireman switch wiring:
T101P201 has a fireman's switch that wires directly to the pool heater thermostat.
http://waterheatertimer.org/pdf/Intermatic-Firemans-switch-156T4042A.pdf
If you are not using the timer for pool heater, or if heater does not have connection for fireman's switch, then do not connect fireman switch wires, and just tape them out of the way.

This unit (WH21) was installed 1 mth. ago. This is my second unit I've installed with the first being for a friend and his has "NO ISSUES". In the last week mine the second unit has failed to...


You probably have defective timer.
I test timers, and some timers arrive defective.
I have not tested WH21, so check with your friend about the indicator light.

Mechanical dial timers make audible noise, and dial should rotate as time passes and keep exact time. If dial is not rotating correctly on new timer, then something is not working correctly. The level of timer is not an issue. It sounds like the motor gear is not engaging with dial.
To test timer noise, click manual override lever. You will hear same noise each time timer turns on-off.

WH21 is SPST 21amp timer which turns off one hot wire to water heater.
WH21 is rated to work on 4500Watt 18.75 amp water heater. Or smaller wattage.
Check label on side of water heater for wattage. WH21 is not rated for 5500Watt water heater.

There are many water heater timers:
Electronic timers give more precise time control and option for shorter on-off periods.
Electronic timers are quieter and don't need to be reset after power outage.
http://waterheatertimer.org/Boxtype.html

More expensive Intermatic WH40 timer is rated for greater capacity, and has replacement motors and trippers. WH40 is noisy too, but will last for years. WH40 is SPDT so it turns off both hot wires to water heater. I prefer SPDT, and have tested WH40 and other timers shown on link above.

New intermatic T101 timer problem - timer is not


Manual override lever is good overall test of T101 120Volt timer.
T101 timer has 3 terminals: A 1 2

See wiring diagram on following link:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

Electricians test, they don't guess.
So test your wire:
Separate all wires for testing.
Use ordinary 2 prong tester.
Tape wood sticks to tester leads to keep hands away from power.
Stand on dry boards. Do not hold or touch anything metal.
Turn power ON.
Test each wire to bare ground wire.
Tester lights up on Hot wire. 120V circuit has only 1 Hot wire. If you have 2 Hot wires, you might have 240Volt circuit and need T104 timer. If circuit has 1 Hot wire, then that Hot wire must connect to terminal 1.
If you have NO Hot wire, then check circuit breaker.
Hot wire is identified.
Now test Hot wire to all other wires, except bare ground wire.
Tester lights up on Neutral wire. Neutral wire must connect to terminal A.
If you have NO Neutral wire, then additional wiring is needed, or circuit needs further testing to see what type of wiring you are working with.
Bare ground wires connect to green ground screw.

Notice there are small white wires also connected to terminals A and 1. These small white wires power the 120V clock motor. With Hot on terminal 1 and Neutral on terminal A, the clock motor will run, and yellow dial will rotate.

If timer dial does not rotate after connecting Hot ans Neutral, then test voltage across Hot and Neutral to make sure it reads 120V.

Your circuit should have 2 wires remaining.
These wires go to 120Volt load (fan, light, motor)
Connect these two wires to terminals A and 2.
Try manual override.
If Load turns ON-OFF, then timer is wired correctly.
If Load does NOT turn ON-OFF, then reverse Load wires on terminals A and 2.

The dial on the intermatic water heater timer is not rotating on it's own and is easy to turn in either direction-without pulling it out and setting the time. The unit is only 1 year old..Can I replace the...


You can replace clock motor on many Intermatic timers:
Snap mechanism loose using metal spring top inside box.
Tip mechanism out and get clock motor number off motor.
Google search specific clock motor number.

Aplus sells many clock motor:
http://www.aplussupply.com/intermatic/timermotors.htm
Electric supply online sells clock motors
http://www.electricsupplyonline.com/prod/intermatic-motors.php

Grainger carries inexpensive clock motors for T101, T103, T104 timers.
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi
T101 and T103 use 125v motor
http://www.grainger.com/Grainger/INTERMATIC-Time-Clock-Motor-1PNK1?Pid=search
T104 uses 240v motor

I get lights when I turn the switch to on but as the timer advances, it doesn't trip and turn the timer on


You posted under Intermatic T101 timer.

1) If this is new timer installation, it sounds like black wires on terminals 1 and 2 are reversed.
Other cause could be the ON-OFF trippers not positioned on timer dial

2) If this is old timer that worked before, then tripper pins could be worn down.

I have a problem with my wh21 intermatic hot water heater timer.When it trips off the indicating light is still on dimly and there show low 92 volt on load side.


There is a short. The timer mechanism is mechanical, so the problem is not failed electronics.
The WH21 is for 240 volt circuits, so it has 2 hot wires and 1 ground from the breaker box. Only one hot line to the water heater is turned off, but both lines are attached to screw terminals at timer.
To see if the problem is a shorted element or shorted wire in water heater, disconnect hot leads to water heater one at a time, and then test. Then disconnect ground wire from water heater and test again. Then disconnect all wires to water heater, and test again.
If the problem is in the water heater, search for troubleshooting steps on internet. Focus on testing elements.
If the problem is not in the water heater, then a frayed wire on back of timer is next checkpoint. The timer motor is the final suspect. You can detach the timer motor from the housing, and test for stray voltage. Intermatic WH21 is inexpensive to replace.

T101


Here's the wiring diagram:
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/t101%20-%20english.ashx

The wiring is as follows:
Connect _both_ the incoming and outgoing neutrals (white) wires to the "A" terminal. The incoming [(LINE) (hot) (from the breaker or source)] black wire is connected to the #1 terminal and the outgoing (LOAD) black wire is connected to the #2 terminal.
Both of the bare or green wires are twisted together along with a 6 inch or so pigtail using a red or yellow wire nut. The pigtail is then connected to the green "GR" screw on the enclosure.

I need to instal a mechanical time switch


john, i'm assuming the water heater is 240 volts and the timer is 240 volts, if ok follow these instructions. the 2 wires coming from the breaker box goes on 1 & 3 screws, also each yellow wire going to the timer motor goes on 1 & 3. now the 2 wires going to the water heater goes on 2 & 4. be sure to ground the timer box
