I don't have instructions to program a Noma timer . It has a time and mode buttons but I have not been successful in trying to figure it out. What does P , C and E modes indicate.

Noma makes so many programmable timers and they are all different. Your best bet is to track down the Noma website and look for customer support.

The C stands for current time, you ned to program that 1st, a dot after the HR indicates PM
P indicated start of program, push time button unitl desired on time remember a dot appears after th PM hours. Press mode button & an E appears, end time, press time button to get selected off time, a 12 with Dot means it ill go off at 12 midnight, a 1 w/o dot means 1 AM

KM are you saying this is the sequence for all Noma timers?
