How do I program hpm time switch hl03705 very hard

Hi Brian
First thing to note about this timer is that it has a button battery to hold your program & keep the LCD display alive. Use the release tab in the lower left corner to separate the timer from the relay mechanism. Not only does this allow access to the battery, but It is also easier to program this way without having to stand in front of your electric box with a torch, trying to program the unit. It can then be returned when set up to your requirements.
Programming is quite straight forward once you get used to it's idiosyncrasies.
It is all controlled by the tiny joy stick which also has a push button in the centre.
Start by pushing the centre button straight in, It will then show a list of functions. Use the up / down side of the joystick to choose the function you want.
If you just want to turn your device ON for example (with the front facia back in place in the switchboard) just click down past the bottom of the visible list till you see ON. Then press the centre button in. You will hear a click as the relay turns ON. Repeat the same for OFF or AUTO. The unit would normally be left in the AUTO mode to perform it's programmed timing routine.
There is also a RESET position which clears all data to allow you to start over, clean.
Use this same method to set the TIME & DATE. Use the joystick left & right or up & down to set the right time & date.
It has enough smarts to figure if it is day 1 or 7, seen in the LCD bars at the very top under plastic 1-7 numerals.
When your ready to set the timer up for the Turn On & Off times that you have chosen then press the CENTRE BUTTON IN and use the up & down joystick to select "PROG" for programming.
Note that on the lower grey plastic sides of the LCD display there is the letters stamped On on one side and Off on the other.
You use this as an indicator when setting up your ON & OFF times on the LCD display. The LCD display only puts a black marker on the actual LCD to indicate your chosen times.
You will use the up / down joystick to line up the time of day that you want and the Right joystick to mark all the spots between the hours you choose.
Very hard for me to get to specific here without running in and out to my timer, So.... remove your timer control facia and sit down somewhere comfortable & undisturbed and play around with these settings until you get them right. Then carefully plug the unit back in and .... voila... your in business.
Now.... back to finding a replacement for my timer which has bad contacts and sometimes won't turn the hot water ON when it should. 7 Years of On / Off for the hot water aint bad!

NOTE:
This is a seven day timer. At the very top of the LCD Display, from left to right you will see numbers engraved in the plastic. Once you programmed your date, there will be a tiny LCD mark under one of these numbers to indicate what day of the week it is 1-7.
When you have decided what hours you want the timer to turn ON & OFF, you will notice a tiny mark under position 1. You have actually only programmed position 1.
To program the other days of the week this timer has no shortcuts. You must continue the time programming (using joy stick) past 24 hours (Into the next Day) for it to move to the next days settings. Continue further for the remaining days of week. You will notice a notch under the etched plastic numbers. This indicates wether your programming a turn ON time for Monday thru Sunday.
It's definitely a pain to set up if you aren't aware of how it's done. Cant find a manual on line as a PDF file.
I will look through my paperwork and see if I still have the programming chart!

Good Luck with Yours
