Get a manual. The system is easy to program if you have one. Just realize that the memory battery is probably dead. If you do not replace it, you will need to reprogram the system every time you lose power.
Also, even when they were new, the old Macrotels did not keep good time. Frankly, I would not waste my time setting the correct time and date as it will be wrong again in a few days.
Lastly, double check the model of your KSU before purchasing a manual.
