You need a delay contactor block that attaches to top of LC1D4011M7 contactor:

Connect power to contactor block.
Connect Load to other side of contactor block.
When contactor activates, it activates delay timer.

1) Copy following links for illustrations showing timer controlling contactor in 3-phase environment:
http://waterheatertimer.org/How-to-install-3-phase-timer.html

2) Substitute thermostat instead of timer for switching control.

3) I don't know what thermostat you have, or if it's functioning or the rating.

4) Which contactor do you have?
Do you have a 3-phase contactor??
Or two-pole single phase contactor?

5) Match thermostat output voltage with contactor voltage:
Thermostat output is 24 volt? Then use 24Volt coil on contactor.
Thermostat output 120 or 277 > then use contactor with same coil rating.

6) More information is needed.
I don't understand description of your wiring.
Add a comment and compare with illustrations sent, so I can visualize ... or attach photo and/or give product numbers so maybe I can locate wiring diagrams.

1) Copy following link for wiring illustration ... assuming timer is supposed to control pool pump:
http://waterheatertimer.org/images/T104-to-contactor.jpg

2) T104P is 240Volt (208-277V) SPDT timer in P plastic outdoor enclosure.

3) Jandy AE-TI is 208/230V pool heater.

4) Page 13 of Jandy manual shows single-phase residential wiring diagram.

5) First of all, power to main contactor is not interruped by timer, since this powers 24Volt transformer that controls the chip board and general operation.

6) The timer is connected to 'Auto-heat contactor.'
The confusion is what Load connects to this contactor? The water pump? Load is shown on diagram as 'pump time clock.'
I assume the load is the PUMP??

Each timer has a contactor.
Timers can also control a contactor.
Which timer do you have?

Here are contactors, with some illustrations showing tiimers controlling contactor:

Here are example timers controlling a 3-pole contactor for 3-phase application:

Question is not clear.

You posted about Dayton on-delay timer?
This timer has two contacts, and wires similar to a light switch.
Connect 120V power to terminal 1
Connect wire going to load to terminal 3
Maximum Load is 1 amp so this timer should be wire to a contactor/relay and not directly to Load.

If you have Dayton off-delay timer, open following link for wiring diagram, and to see examples of contactors:

If you have a different timer, then add a comment with clear description of timer or in-focus photo of timer posted on Flickr

Check the contactor for power to the coil. You may have not gotten that contactor wire connected to the input power lead when you re-connected your Timer. Also check for 12VDV on both sides of the contactor. You may have 12VDC in but nothing out which means the contactor is not energizing.
Power for the contactors' coil is supplied either with manual selected or Auto and the timer set times are active.
Yu need to find out why the contactor is not being powered. In your case I just think it is a missing wire connection due to the fact that it was fine before you moved it.

Thanks for choosing FixYa,

Your solenoid is not installed correctly. There is a battery side and a starter side ... there is a contactor inside. When you turn the key on, you actually energize an electric magnet that causes the contactor to complete the connection between the battery and the starter. Since your starter operates when the battery is connected, it seems to me that the electric magnet is energized incorrectly.

your relay coil is loose and its a mechanical vibration due to the a.c. current flowing and reversing every 120th of a second

Hi8 , contactor in electrical is the one who connect electrical to a certain equipment , magnetic contactor is operated with electromagnetic contact supplied low dc voltage.
