available in operation mode. To select a preset, press the
select key momentarily. The first preset "P_" will appear. Press
the Select key momentarily again to select another menu
preset or continue to press the Select key momentarily to
scroll through the menu presets.
Reviewing Operating Setpoints

Alarm
If air temperature is < (less than the (Air setpoint – 10°C or
18°F) or > (greater than) the (Air setpoint + 10°C or 18°F), the
air temperature display will flash. Pressing any key will stop
the display from flashing.

Air Set point temperature – Water Set point temperature in Fahrenheit
Calculating the Water Temperature
To provide a simple and consistent means of setting the
chamber humidity we have created a relationship between
the water temperature and the air temperature where the
lower heat source is scaled in percent relative humidity.
By setting the humidity to minimum (10%), the lower
temperature will match the air temperature. In applications
where it is necessary to set the lower element temperature
less than the air temperature in dry mode or for a reference is
humidity mode we provide the preceding chart to calculate
the set point.
