20 Most Recent Intermatic HB88RC - 7-Day Programmable Outdoor Timer - 15 Amps - 120 VAC Li Questions & Answers


Just program it as noted previously and put the timer in Auto. Set the clock to 1 min BEFORE your earliest timer program is set to come on. When the clock hits the correct time, it will turn on. Then set the clock to the correct time and you're golden.

No, you do not need to set all 7 timer events.
When event1 ON and event1 OFF are set, press CLOCK button to exit programming and save programs. Or press PROGRAM button and move to event2 ON and event2 OFF. Exit programming any time by pressing clock button.
http://www.intermatic.com/products/timers/consumer%20outdoor%20timers/digital%20timers/hb88rc.aspx

That being said, if events conflict with each other, timer will not operate.
For example event1 ON FR at 7pm and event1 OFF all-days at 11pm.
The days have to match for on-off times.

Another example event1 ON FR at 7pm and event1 OFF FR 11pm, but event2 ON all days 8pm event2 OFF all days 10pm. This overlap will cause timer to skip programs.

If timer is being used in random mode, timer programs cannot be closer than 1/2 hour apart.

When programming is done, press clock button to display current time.
Timer should be ready to go.
Manual is fuzzy at this point, and does not specifically say, but it appears that you only press MODE button when you want to set another mode beside auto.
I e-mailed Intermatic last week about this unclear spot because several folks are writing in about this timer not going into correct MODE after programs are set.
MODE must be set to automatic
Press MODE button once for manual override function
Press MODE again and RDM displays for random >> this is for lights turning on randomly when on vacation.
Press MODE button third time, and AUTO shows on display >> you want timer in AUTO for timer programs to operate.
Here's the trick ... after setting MODE to auto, press clock button to display current time

If timer will not enter AUTO, then timer is defective.
If Intermatic sends response that is pertinent to your question, I will post again on this thread.

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.

Try removing AA battery from back of timer.

Question posted under HB88RC 6-button outdoor plug-in timer with battery compartment located on back of timer.
Instruction manual does not say how to reset timer.
Other newer timers are rest by removing battery.
HB88RC is replaced by newer HB8800 series with lifetime warranty.

This timer is reset by removing battery.
If functionality is not restored with battery replacement, timer has gone bad. Try timer on different outlet, and with different Load. Test outlet with circuit analyzer.

You have nice website.

Most digital timers suggest resetting as last-step effort to restore functionality.
This particular timer is reset by removing battery.
Try removing battery again. Otherwise it seems the timer has gone bad.
HB88RC is discontinued product.
Replacement is heavy-duty Intermatic HB800RCL 2-outlet or HB800RCH 1-outlet timer.

Less expensive and less reliable timer Woods 59403 with 1-outlet has quite a few 'timer won't work' questions on fixya.

First we need to identify the timer.

If you want to take a few moment and add a comment with a description of each button timer, and shape and purpose of timer, I might be able to identify the timer and will post instructions.
I have extensive files on timers.

Also look at timers on following pages to see if your timer shows:
http://waterheatertimer.org/Woods-timers-and-manuals.html#6-24
http://waterheatertimer.org/UPM-timers-and-manuals.html
http://waterheatertimer.org/Tork-consumer-timers-and-manuals.html
After identifying timer, add a comment and I'll post those instructions.
Most timers shown on pages above also have link to a manual

If you do not want to add a comment and identify your timer:
You can also take advantage of fixya phone support.
Fixya expert will walk you through the steps for a price.
