How do you delete a program Intermatic hb88rc

Try removing battery, and then reprogram timer.

Some timers are reset when battery is removed.
Newer digital timers keep programs in memory when battery is removed, but in that case the instruction manual shows steps for resetting timer and deleting programs.

The HB88RC manual does not show steps for deleting programs or resetting timer.

I purchased a 1875 watts Timex Heavy Duty timer Model # 12-881 to connect to my 1200 watt water distiller. The timer is burned and has melted where the distiller was plugged in. We were furtunate...

Timex 12-881 timer has 3-prong outlet and is rated 15amp 1875 watts.

The timer melted because too much amperage was drawn across the connection and timer got hot.
Different things can cause this.
Phony rating, and/or mis-manufactured timer.
Defective timer.
If distiller has a motor, then it will draw more amps at start-up.
Timer is rated for incandescent light bulbs only.
Many timers say 1875 watts resistive, but instruction sheet will show 1000Watts incandescent and 1/4 HP horsepower.
Timer is plugged into extension cord.
Cheaply built product, not meant for constant use.
Timer outlet and distiller plug did not meet firmly, so connection heated up.
Turn off distiller before plugging into outlet so no spark is at the connection point.

I recommend appliance timer for operating appliances.
For example Intermatic HB 113 timer.
Also heavy duty portable timer like Intermatic P1121

My son lost the instruction manual for our DT 500 CH self-adjusting timer made by INTERMATIC INCORPORATED, and we can't even figure out how to turn it on, let alone program it. Any help would be great!...

I Just downloaded the pdf for the same model. The link to Intermatic is

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.
