The optional technician adjustment procedure allows temperature and humidity offsets, °F or °C
display units or display information to be changed at any time. When the unit is powered up,
pressing the tact switch at SW1 will enter the user calibration adjustment mode (See Figure 4).
When pressed, the LCD will show page zero, P0. The page numbers auto-scroll to P5 and then
the unit returns to the normal run mode. Pressing SW1 when any page number is displayed will
show the calibration value that is associated with that page. The variable will auto-scroll and will
show all the allowed values for the selected page. Pressing SW1 when the variable value you
need is shown will record that value and return to showing page numbers.
* When active means when moving the setpoint slider.
** Display toggles through selections.
