It should be on the door. It's marked 'line' & 'load'. Line is un-switched coming in and 'load' is your output to your motor or whatever you're running.

How to install photo cell on timer

You posted under T1471BR timer.
This is a 4PST timer
Do not install photo eye on input voltage from breaker box, because that will stop timer clock from operating except nighttime, and then clock time will be off.
The timer clock terminals are A and B, so Connect white neutral to terminal A and black Hot wire to terminal B.
The terminal switch terminals are dry and receive no power when input terminal A and B have power.
Copy following link for illustration showing typical timer wiring.
Using illustration above: If You want to add photo eye, Remove black wire from terminal 5 to light bulb. Then Connect photo eye black wire to terminal 5, connect photo eye white wire to white wire at light bulb, and connect photo eye red wire to black wire at light bulb.
Copy following link for Intermatic T1400 series product manuals, 3-phase wiring, etc

Where can I find the manual for the Intermatic Incorporated Timer, Spst-125V 24Hr Mechanical 2 On/Off - PB913N84

There is no manual specific to the PB800-900 series timers.

Timer uses 107TTN222 ON tripper and 107TN221 OFF tripper.
Push trippers onto dial at times you want timer to turn on-off.
Rotate dial until current time lines up with arrowhead located in center of timer dial.
images show that timer has override knob that can be rotated.
Timer has 4 terminal connections. 2 connections are for 120Volt clock motor, and 2 terminals are the switch for turning Load on-off.
Black hot wire and white neutral wire connect to clock terminals.
Switch terminals are dry.
Dry terminals mean they have no power when wires are connected to clock motor.
The switch terminals wire just like ordinary light switch: Power connects to one of the terminals, and wire to Load connects to other terminal. Neutral wire does not connect to switch terminals, just like wiring an ordinary light switch.
Offhand I do not know which set of terminals is for clock motor.
Use continuity tester on each set of terminals.
Clock terminals will show continuity at all times, no matter which position override knob is set.
Switch terminals will show continuity with override knob in one position, but not the other position.

I am replacing an Intermatic T101 125v time switch dial with a GE 15600 replacement time switch module. The intermatic has posts A 1 2 3 4 and GE has L 1 X 2. How do these map to each other?

GE15600 replacement module snaps into standard Intermatic box.

Timers can be wired different ways. I know all these timers and have them sitting in my office.
I cannot see your timer or your wires, so read information below.
Open following link for clear crossover instructions:

If Intermatic timer has terminals A 1 2 3 4, then that is not traditional T101, but sounds like 120Volt T103.
T103 can be wired many different ways, and is not fully compatible with GE replacement.
If you have wires on all terminals A 1 2 3 4, then add a comment and say what wires you have and what loads you are controlling, for more detailed information.

For other folks who find this link, it is sometimes less expensive to repair T100 series Intermatic timer with $4 trippers and $20 clock motor.

4000 series is 24 hour repeat timer

3) To buy replacement timer, Intermatic crossover guide shows T104M used for pool and spa controls and to replace timer mechanism
T104M at amazon

1 year old t101m timer stopped working. The manual on/off works but mechanical clock doesn't. Is there an easy fix or should I just repalce?

T101 dial is not working so the 125V clock motor needs to be replaced:
Grainger sells 125V T100 series clock motor:

Timer mechanism releases from box with metal spring located inside top of box.
Clock motor is attached with 2 star screws.
Notice clock motor has plastic gears, but timer has metal gears.
Metal gears on timer mechanism last for many years.

Notice also that clock motor wires connect to terminals A and 1.
After installing new motor, tighten screws very tight against copper wire.

I HAVE AN iNTERMATIC t100m TIMER it appears to have two "off" tripper levers but no "on" tripper lever attached to the clock face dial by a set screw . Do I need an "on "...

Yes, the T101M 120Volt pool timer requires both ON and OFF trippers:

Grainger sells T100 series on-off trippers:
Amazon sells T100 trippers

Grainger sells the T100 125V clock motor

How to wire T-101 120Volt timer

How Intermatic dial timer clock works.
Clock motor rotates dial.
Intermatic clock motor, located on back of mechanism, are replaceable
Trippers located on outer edge of dial push on-off lever
ON tripper pushes lever one direction
OFF tripper pushes lever opposite direction.
Lever pushes electrical contacts together and pulls contacts apart.
When lever moves, manual override also clicks back and forth with audible click.
To replace timer, replacement snaps into box without needing to changing box.

I'm in need of an inexpensive timer, preferably mounted in a wallswitchbox, which has two output circuits, one from a n/o and one n/c contact. Can you recommend a model? Thank you

Instruction sheet
Sales sheet

Deihl spa-and-pool timer shows a 15A DPST NC NO timer in sales sheet
Wiring diagrams show DPST.
However most 880's sold are 125V SPST.
Deihl makes 125 V, 24V and 240V models ... but I don't have product sheet that shows all models

I don't see any NO NC wall-timers while looking at: Woods, GE, Intermatic, Aube, Hagar, Leviton, Lutron, Paragon, Pass and Seymour, Swilight, Sylvania, Timex, Tork, UPM, Utilitec

Box timers by Intermatic offer NO NC:
T1900 series

Ordinary 3-way switch is NC NO
Ordinary 4-way switch is NC NO can be wired to control 2 independent circuits

There are heavy load NO NC contactors (relays)
Item 2cg37
You can wire ordinary wall timer to control the contactor

How to wire this T2005 SPDT to 2 circuits

Here is the link to Intermatic... you can find the wiring diagrams for any timer there...

Need a picture of an already wired T2005

You are placing a pretty tall order here. You want someone to go to a timer that is wired - take a picture of it, transfer it somehow to the computer then attach it here somehow and or draw a diagram ... and for what benefit???? There is a schematic on the door of the switch, at least the dozen or so that I maintain anyway.

There are three termnals in the switch, a common for a white, a hot black and a switched black.

The "line" is the hot black and a white. Your load (white can come to the line white if you want but it is not necessary) a black wire that goes to your light or motor or what ever you are turning on.

If this is a two pole switch (220 V AC) please indicate in your question/response.

If I have misunderstood your question, pleae ask again.

thank you
