relay is showing 'off'. Why doesn't it turn on?" The answer is that the DT-7 does not check
what time it is and then look to see if it is "supposed" to be on or off. It just advances its clock,
minute by minute, and when it encounters an instruction, it executes the instruction. On initial
set-up, use the test button to put the unit in the desired initial state.
If an on and off instruction both occur at exactly the same time and day, the off instruction
will be executed and the on instruction will be ignored. An instruction is erased by
incrementing the hours, minutes, and day buttons to restore the horizontal (null) lines. Note
that momentarily pressing the reset detent will eliminate all program data from the unit as well
as eliminating the time setting. The reset detent has the same effect as removing all power
(including the battery) from the unit.
