Main menu display
When unit is first plugged in to AC power, the control
panel display will briefly cycle through a series of
displays. This is part of the unit’s self-diagnosis
procedure and no user intervention is required.
Once the self-diagnosis is complete, the display will
show the following information:
UNIT ON 00 HRS
INLET 00°C / INLET 00%
The first line of the display shows the total number of
hours the unit has been in operation. This value may be
reset to zero to track job hours (see “Job Hours Reset”
below). The second line of the display alternates
between inlet temperature and inlet humidity.
When fitted, the optional LGR1800i wireless transmitter
continuously seeks a connection with a HygroTrac
gateway. When a connection is established, a wireless
symbol
appears in the lower right corner of the
display.
No information is presented on the display when the unit
is not plugged in.
User settings menu
A number of settings may be changed by the user.
System information is also available. These items are
accessed by pressing the
DISPLAY MENU key. Each
press of the key will display the next parameter (see list
below). When you reach the parameter you wish to
adjust, press the
MENU SELECTON key to increase
the value. Press
DISPLAY MENU again to accept the
setting and re-start the display cycle. If no keys are
selected for 20 seconds the display will automatically
reset and return to the normal display mode.
