pool pump timer

[Mark1]

I have an inground pool that is running on a 2 horsepower 240 volt pump. I want to install a mechanical timer on the pump. Which timer should I get?

[rob the builder]

intermatic... if you want a mech. time box.

Legrand if you are in the EU (I assume so with 240v). Also mechanical and very reliable.

I Have an inground pool. When I turn the light ON, it stays on for 1 minute then it goes OFF then ON for 5 seconds then OFF and so forth.
Changed the bulb from 300W to 100W, the time of ON increased but it is still going On and OFF.
No water on the fixture.
If any one can help. it would be great.
