I recommend calling Intermatic.

Timer prompts user through the set-up and programming.
The manual does not show exact steps.
Example programming on page 17 of manual does not show how to set timer for 'fixed' 24-hour operation, with specific on-off set times
http://waterheatertimer.org/pdf/Intermatic-et70115c.pdf

Intermatic does not show that manual.

Intermatic manuals:
http://www.intermatic.com/customer%20service/instruction%20manuals.aspx

They show HB77R raintight.
This model may be close enough to figure out button sequence.
I work with timers and most programming follows similar pattern.
Older timers usually follow same pattern as new timers, except with fewer options.

DT121 Manual
http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/dt121c%20-%20english.ashx

Intermatic does not show DT11
Intermatic shows the DT121 is no longer available

If the display shows and you can set programs, then the battery is good.
Does the manual override work? This indicates whether the timer on-off switch operates.
If manual override does not work, then I discovered that timers are no longer any good

Programming:
Set present time
Then set ON time for program 1
Set OFF time for program 1
Then set ON time for program 2
Set OFF time for program 2
Most timers will not function if there is a conflict in programming > for example Program 1 says ON at 6 and OFF at 7 and Program 2 says opposite or has overlapping times
When events are set, press SET once > this will put timer in RUN mode

If manual override works, and you set programming correctly, but timer does not carry out instructions, I guess the timer is no good.

Intermatic has 24 hour timers with 2 on-off per day
http://www.intermatic.com/products/timers/consumer%20indoor%20timers/lamp%20%20appliance%20timers.aspx
Intermatic has 7-day digital timers (all digital timers today are 7 day where you select the day that each program works)

Go to www.intermatic.com Notice there is a recall for this model timer with codes 40z to 52z. Contact Intermatic for replacement. Here is link to the DT-17C probably same instructions.

Here is a link to the manual from www.intermatic.com

I Just downloaded the pdf for the same model. The link to Intermatic is http://www.intermatic.com/~/media/files/intermatic/products/instructions/timers/dt500ch.ashx

If that doesn't work then google Intermatic DT500CH pdf and select the return from Intermatic. It's a good timer but not intuitive. I had to look up the manual just to change from daylight savings time.

That is the visual indication for a "LO" battery. You need to replace the battery very soon or the timer will cease working properly.

Typically with this model of Intermatic timer, you only have about 30-40 seconds to change out the battery before the programming is erased and you'll have to re-enter your desired on/off cycles and such.

The battery is located under the manual push faceplate, just flip it down and you can either use a small flat bladed screwdriver or your fingernail to open up the battery compartment to change out the battery.

Hope you find this Very Helpful and best regards!
