C4 Manual Rev 7.5.2
When the Probe (substep 4) is specified as 7, the program step turns the optional
load control port off. Substeps 0 - 2 are ignored. Upon power up and changing the
rotary switch this port will be on
. At start and end of program execution, this
port will be automatically set to off.
6.9 Common Programming Issues
6.9.1 Step Numbering
Remember that the first step or substep is 0 instead of 1.
6.9.2 Changing Substep Values
When changing a substep value on the right half of the display, you must use the
<CLEAR/ENTRY> key to clear the previous entry from the display before entering
a new value. Then enter the new value by keying on keypad, then press <ENTER>
to store that new value.

Refrigeration compressor and optional aux/power control ports will return to their
default values of On (HI) and Off (LO) respectively upon changing the setting of
the rotary switch. However before the start and after the end of a program they
will both be LO.
