BRINKS MODEL 42-1020 A 24-HOUR TIMER WITH 15- MINUTE TRIP SETTINGS, 15-AMPERE, 120-VOLTS.

1) If you have programmable timer, then it would require 24 ON and 24 OFF settings, with down-to-the minute programming.
1 ON for each hour.
1 OFF for each hour.
Following link shows Grasslin 50-60 Hz 230Volt din rail timer with 50 memory slots. 16 amp at 230 volts

2) If you have 24 hour mechanical timer with dial, it would need 24 ON trippers and 24 off trippers with down-to-the minute schedule.
No timer has that capability.

3) There is C8800 series cycle timer. 120-240Volt 60Hz for US market. 20 amp at 120volts, or 20 amp at 240Volt. Chose 1 hour cycle, then insert 100 trippers and leave 20 blank spaces.

For example CT2000. Rated 120Volts 60 Hz for US market.

Brinks 42-1020 is analog timer with 48 segments (pins) located around edge of dial.
Each segment (pin) represents 15 minutes in 24 hour day.
Segments on this timer push down and outward.

Open following link to identify TM311 timer:
http://www.amazon.com/Intermatic-TN311C-Heavy-Grounded-Timer/dp/B00002N5FO

1) First of all, you would need more turquoise 107TN222 ON and red 107TN221 OFF trippers.

2) BUT big problem is that TN311 time dial is divided into half-hour segments, so minimum on-off is probably 1 hour since it takes 2 trippers for on-off cycle, and width of 2 trippers is same width as 1 hour.

3) Open following link for plug-in timers with 15 minute segments shows Woods 49664 & Stanley 31192 & Sylvania SA110
http://waterheatertimer.org/Woods-timers-and-manuals.html#49664

4) Notice the 49664 dial, that each hour is represented by 4 segments. This says timer on-off period is 15 minutes.

To set this timer, you would pull up all segments around the dial, and then push down 1 segment for each hour that you want timer to turn on for 15 minutes.

5) TN311 has 3 prong grounded outlet, Woods 49664 has 2-prong outlet.

6) Stanley 31192 timer and Sylvania SA110 have 3-prong grounded outlets and 15 minute intervals.

7) You cannot accomplish 15 minutes intervals for 12 periods a day with programmable digital timer.
Most digital timers allow 1 minute program times, but are limited to 6 or 7 programs, and not the 12 separate on-off periods needed for your project.

I don't think the timer runs on 240 volts does it? You can switch 240, but the timer uses 120 volts to run. You might check the connections and timer clock rating more closely. Also, the 'off' & 'on' trippers are different, make sure you use the right one.
