Need wiring diagram for Intermatic 240V Mechanical Time Switch

I just bought this product to replace the manual switch for my pool pump. Trying to be green, and save money. Problem is that the wiring diagram is meant for a trained electrician, which I am not. Can anyone be more explicit, and call out the wiring connections.  Terminal 1 & 3 on the switch each have a white wire that runs behind the timer. Terminal two and four have nothing attached.  Thanks

For anyone else who may be reading this post, these instructions are for the T104 ONLY.
Connect your incoming line) 240 volt wires to terminals #1 and 3. Connect the outgoing 240 volt (load) wires to terminals # 2 and 4. Don't forget to connect both equipment ground wires (bare or green) to the "GR" terminal.
Do NOT connect anything to the "A" terminal.

I have a T104 timer that runs my pool pump. I also have a switch that lets me turn on the pump from my house. The switch is wired to the timer. I switched out the T104 with the same and I think I messed up the wiring. Can you set me straight? Also how do you wire a "jumper" from one timer to the other( pool sweep to pool pump? Thanks for the advice!!

Thank you! I had this exact question...Being my first venture into wiring, the 'A' terminal appeared to be the ground...had I not found this post, I would have made what I now realise to be an elementary wiring error.
Only suggestion I could make, is to direct the reader to where the Ground is (located near the bottom of the box, inside), which unfortunatly, is niether labled or indicated on the provided instructions.

Intermatic t1202T 240v dual pool timer. Main pump continues to run and manual overide will not shut it off. Changed the timer mechanisim and same thing. Disconnected the Freeze control and it wil


Maybe the PF1202?
Probably just the freeze thermostat and not the relay.
Disconnect freeze thermostat wires from relay... and substitute a single-pole switch.
Be careful... power is ON

Do not leave the single-pole switch connected since 15 amp rating of typical switch is less than amp rating for 40 amp pool centers

I need help to install pool pump to mechanical intermatic timer switch GE to replace the digital control.


Question is not clear.
Add a comment with missing information for exact wiring diagrams.
Voltage is not known.
Timer model numbers are not known.
You have two timers.
You are replacing unknown electronic timer with unknown mechanical timer.
Intermatic timers and GE timers are different companies, and each makes many different timers
Each box timer has identification on inside of timer door.
Open following links to help identify timer and see wiring diagrams.

How do I wire a 220 volt two speed swimming pumpmotor using aground fault circut creaker


More information is needed.
Is the circuit breaker 240Volts or 120V?
Is the pump 240V?
What kind of switching timer is connected to pump?
What color are your wires?
Read information below and then add a comment.

Typically, the pump is 240Volts.
Pump is wired to mechanical timer with NO NC contacts for example GM40 series:
http://www.intermatic.com/products/ec%204%20layer/mechanical%20time%20switches/24%20hour%207%20day/gm40%20series%20multi-voltage%20time%20switch.aspx
http://waterheatertimer.org/Intermatic-timers-and-manuals.html#GM
The timer sends power to one speed or the other speed but not both speeds at same time.
Timer can be mechanical or digital.
Mechanical timer is used if pump is supposed to be ON at all times.
Digital timer like P1353 is used to control pump more exactly.
http://waterheatertimer.org/Intermatic-trippers-and-parts.html#P1353
See example1 for 240V
http://waterheatertimer.org/images/P1353ME-2-speed-motor-500.jpg
Timer is rated or set for 240Volts.

GFCI protected 240Volt line leaves circuit breaker and goes to timer. Then timer and pump are both protected.

Need wiring diagram for T104M 208-277v Mech. Time Time Switch


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

Below is a larger and better diagram of a 240V connection Terminal connections are White to White on 3 & 4 Black to Black on 1 & 2:
http://waterheatertimer.org/images/T-104-control-240V-Load4-35.jpg

More info: http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

I am assuming you have the 240 VAC clock motor so the clock timer motor wires are connected to terminals 1 and 3.

If you only have the 120 VAC clock motor the wires will be connected across terminals 1 and 2.

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.

My timer for my water feature looks like your Intermatic T101R3 timer. I do not have an instruction manual. Can you e-mail me some simple instructions for using this so I won't get charged an...


T101R3 is outdoor pool timer with fireman's switch.
Some are double-pole, some are single pole, some are 240V and others are 120V.
They each look like the other so eyeball identification is not enough information.
The model number should be inside door of timer.
http://www.poolandspacontrols.com/products/mechanical%20time%20switches/pool%20and%20spa%20time%20switches.aspx
http://www.intermatic.com/products/timers/mechanical%20time%20switches/24%20hour%20dial.aspx
http://www.intermatic.com/customer%20service/instruction%20manuals.aspx

I have been unable to locate manual specific for these products, and I have looked.
I was looking yesterday for this instruction manual.
Some wiring diagrams appear on following page, but again it depends on your specific model
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html
http://waterheatertimer.org/Intermatic-trippers-and-parts.html#T100

The T101R series is designed to control pool pump and pool heater.
Fireman's switch automatically turns off pool heater 20 minutes before pool pump is scheduled to turn off.
So you set the trippers on dial, and then the fireman's switch does the rest automatically.

Add a comment with in-focus photo of inside of timer door and I can put together all the information and simplify instructions. Put your digital camera in 'macro' with the flower-symbol to take close-up photos. Photo has to be in focus so I can read information and see wiring schematic.

Hi expert: I am installing intermatic P1353me digital pool or spa mechanism and having trouble to figure out how to do this heater Firemen Switch connection. My existing pool timer is T104 and there were...


1) Fireman's switch automatically turns off heater few minutes before turning off pump.
Not all pool timers have fireman's switch.
If old timer did not have it, then don't worry about it.
P1353 has wires marked for fireman's switch, so simply don't use them if you don't want to.
http://waterheatertimer.org/pdf/Intermatic-P1353-manual.pdf
page 21 of manual shows wiring for fireman's switch.

2) T104 and P1353 comparison
Difference 1: T104 turns OFF both hot wires, while P1353 turns Off 1 hot wire.
http://waterheatertimer.org/Compare-120-and-240.html
Difference 2: T104 controls 1 240V load with 1 time schedule, while P1353 controls 3 different 240V loads, each with different time schedule.
Check that wire(s) coming from breaker can handle all 3 loads.
http://waterheatertimer.org/Color-codewire.html

3) 240Volt T104 is wired as follows:
http://waterheatertimer.org/images/T-104-240-Volt-400.jpg
Hot1 from breaker connects to T104 terminal 1
Hot2 from breaker connects to T104 terminal 3
There is constant power on terminals 1 and 3, each terminal has 120V when combined makes the 240V circuit.
Load1 wire connects to T104 terminal 2
Load2 wire connects to T104 terminal 4
Terminals 2 and 4 have power whenever timer turns ON

4) Definition:
In electric wiring, Line means power from breaker, and Load means wire going to light,fan, motor, pump.

5) Converting T104 to P1353
http://waterheatertimer.org/images/P1353-timer-350.jpg
http://waterheatertimer.org/images/P1353-terminals-566.jpg
Hot1 from breaker connects to P1353 terminal 1
Hot2 from breaker connects to P1353 terminal 2
This will power timer electronics and timer clock and switches.

Jumper wire is placed from Hot1 at terminal 1 to each Line terminals 3 5 and 7.
This will put power at the switch, and when switch turns ON, then power will flow from Line wires to Load wires and then on to the Load.
Load 1 connects to terminal 4, Load 2 connects to terminal 6, Load 3 connects to terminal 8
To complete each 240V circuit, Hot2 is connected directly to each Load.

6) You say 'salt' system connects to terminals 1 and 3 on T104, then those wires are carrying constant 240V to that device. So Salt system connects to terminals 1 and 2 on P1353

7) Get a second opinion:
I frequently contact Intermatic for various problems.
P1353 is fairly new product, and manual is long, and I might not fully understand your problem or wiring.
Intermatic answers their email.

Can you fit a frost switch to the T10404R


http://www.poolandspacontrols.com/~/media/Files/PoolAndSpaControls/Products/Instructions/PF1102.ashx
http://www.poolandspacontrols.com/products/freeze%20protection%20controls/multi%20circuit%20freeze%20protection%20controls.aspx

Intermatic makes a freeze protection control that wires directly into a 240V timer.
If you already have a freeze control, the wiring diagram might help.

geno_3245_59.jpg
The manual has this image larger.
It shows wiring to connect the freeze control directly to one 240V timer.
Intermatic make a freeze control for 1 or 2 circuits.

Timer stopped running so I replace timer motor. However the timer still does not run. I can still turn pool pump on manually. Will I have to replace entire unit?


T103 clock motor is 125 volt WG1570
1) If you bought the 240V WG1573, the clock will not operate
2) If you connected the motor wires to wrong terminals, then clock will not operate.
3) If original box label says T103, but 240V T104 was installed in same box, and you bought wrong voltage motor
4) Test for 120Volts across terminals A and 1, and make sure clock motor matches voltage of timer, and clock motor wires are connected to terminals A and 1.
