TRANSITION VPD SETTING
Adjusts how gradually your device will shift
between levels when triggered ON by the
VPD trigger. This will determine how much
the probe VPD needs to increase to step
up to the next level setting.
The higher the transition setting is, the
wider the VPD gap is between levels. The
lower the transition setting is, the smaller
the VPD gap is between levels. If this figure
is set to zero, your device will jump to your
maximum level when triggered ON.
Press the up or down button to set a
transition threshold between 0.1 kPa
and 1.0 kPa. When the sensor VPD first
reaches or crosses the VPD trigger point,
the level will increase by one (exiting OFF
Mode). Each time the threshold level is
crossed, the level will ramp up by one until
it reaches the level set in ON Mode.
EXAMPLE
In this example, your high VPD trigger is
set at 0.1 kPa, the OFF Mode level is 0,
and the ON Mode level is 6. If the transition
threshold is set to 0 kPa, then once the
sensor temperature reaches or exceeds
0.1 kPa, the devices will trigger to run at
level 6. However, if the transition threshold
is set to 0.2 kPa, then the devices will
trigger to run at level 1 when the VPD
reaches or exceeds 0.1 kPa. It will then
ramp up to level 2 when the VPD reaches
or crosses 0.3 kPa, level 3 at 0.5 kPa, etc.
From 1.1 kPa on, it will run at level 6, the
level set in ON Mode.
