How do you connect the incoming wire to the T103
SOURCE: Bought a Intermatic sprinkler timer. need help.
reading the specs i should say its a timer for only one zone. you can use it for one zone switching or for the pump. sorry.
SOURCE: Trying to replace Intermatic with Utilitech inwall
The wires on your new switch are intended for black = power .. white = neutral . and red = lights .. with two black wires on the old switch I am assuming that there is a bundle of white wires in that wall box, the white timer needs to join that bundle ... then you need to determine which black wire is the power from the electrical panel ( voltage tester) and connect to the black timer wire .. the red timer wire connects to the other black wire in the wall..

SOURCE: 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:

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.
Add a comment any time.
SOURCE: I have 2 intermatic T104M
You might have to add a comment to help sort this out.
USUALLY but not always, if your red wire is connecting to terminal 3 on one timer, then it also connects to terminal 3 on other timer BUT these timers can be wired many different ways.
I have T104 timer on my desk and know the terminal numbers and wiring but I can't see your wiring.

Always take a photo of wiring before starting the replacement process.
Timers should not have both solid and stranded wire connected to same terminal because screw plate will tighten down on solid copper wire, but stranded wire will be loose.
Also make sure that no part of insulation on wires is under the screw plate.
