3.2.5 Setting Temperature Units
The next parameter encountered is for setting temperature units. To set the
temperature unit, scroll through the options by pressing the
adjusting
key
until
the setting matching the desired unit is displayed. The table below shows the setting
value for each temperature unit option.
Once the desired setting is displayed, press
the
setting

3.2.6 Output One Mode and Setpoints
The next parameter encountered is for setting the digital output mode for
output 1
.
There are two main types of output modes for the digital output - hysteresis mode
and windowed mode.
Hysteresis mode has two types of actuations, active low and active high, as
shown on the left side of the figure below.
Active Low: Turns the output off when the pressure has reached the high setpoint
(green line). The output remains off until the pressure has dropped below the low
setpoint (blue line).
Active High: Turns the output on when the pressure has reached the high
setpoint. The output remains on until the pressure has dropped below the low
setpoint.
Windowed mode also has two types of actuations, active low and active high, as
shown on the right side of the figure below.
Active Low: Turns the output off when the pressure is between the high setpoint
(green line) and the pressure low setpoint (blue line).
Active High: Turns the output on when the pressure is between the high setpoint
(green line) and the pressure low setpoint (blue line).
