You need wait 6s after your setting data the module will save the date you have set after 6s. Short press button SET: If you start the time setting mode Nixie tube will blink. You could adjust the time T1 and T2 by button+ and button. Please wait 5s after your setting date the module will save the date you have set after 5s . Long press button SET: if you start the parameter setting mode. There are two group parameter for your choice : P0 and P1. You could switch P0 or P1 by short press SET. Under the parameter P0 and P1 you could set the timing mode by the button+ and button. P00: Timing time mode : 0999s.P01: Timing time mode : 0999min.P02: Timing time mode : 0999h.P10: The relay will connect after you delay the T1 time .P11: The relay will disconnect after you delay the T1 time.P12: The relay will connect after you delay the T1 time first Then the relay will disconnect after you delay the T2 time it finish.P13: The relay will disconnect after you delay the T1 time first Then the relay will connect after you delay the T2 time it finish.P14: The relay will connect after you delay the T1 time first Then the relay will disconnect after you delay the T2 time it is cyclic.P15: The relay will disconnect after you delay the T1 time first Then the relay will connect after you delay the T2 time it cyclic.Example: A customer needs 10 seconds to start up and 20 seconds off. Setup is as follows:T1 set time 10 T2 set time 20P0 0 (T1 time range is seconds)P15 (timer work mode)
