Intermatic T174 wires exactly like the T104 240Volt timer.
Only difference between T174 ans T104 is the day skipper wheel on T174.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T104

These timers are very versatile and can be wired many ways, and changed to control different voltages by changing clock motor wires, or changing clock motor.
Voltages include typical 240Volt. But also 277V, 480V, 120V, 208V and 24Volt

How to wire an intermatic t174 with a W433-1 TIMER FOR A 220 VOLT MOTOR


Verify that the clock motor is 220v. On the posts where the supply wires (line) and pool motor wires (load) they should each have a post for each of their two wires. If you do not have four posts, this is NOT a 220v timer.

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.

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.
http://waterheatertimer.org/Intermatic-trippers-and-parts.html#PB
http://waterheatertimer.org/pdf/Intermatic-PB800-PB900-timers.pdf

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 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.

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:
http://waterheatertimer.org/GE-timers-and-manuals.html#GE-replacement

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.
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html#T101

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.
