Control
Sensor
5.2.2
This screen displays Temperature and Relative Humidity as
measured by the control temperature and RH sensor
inputs. If the controller is configured for proportional control,
the
%RH
value is replaced with the percentage (
%
) of the
proportional input signal controlling humidity production.
The control dew point is calculated by the controller based
on the control temperature and relative humidity sensor
inputs and then shown at the bottom of the display screen.
** See Note 2.
Limit Sensor
5.2.3
This screen appears if the controller is configured with limit
sensors. It displays Temperature and Relative Humidity as
measured by the limit temperature and RH sensor inputs.
The limit dew point is calculated by the controller based on
the limit sensor inputs. ** Note 2.
Conductivity
5.2.4
This screen is displayed if the conductivity sensor option is
selected. It shows the current conductivity in MicroSiemens
as well as the selected scaling factors being applied to the
sensor (low or high).
Control
Points
5.2.5
This screen displays the control points and the actual
values. The top two lines show the set point and the actual
control value and will display in % if proportional control is
configured, %RH if humidity control is configured or in °F if
dew point control is configured.
If Limit is active, then the Limit Active line will appear and
the next two lines show the set point and the actual limit
value and will display in %RH if humidity limit is configured
or in °F if dew point limit is configured.
Cabinet Temperature
5.2.6
This screen displays the current operating temperature
inside the controller cabinet and the "On/Off" operating
status of the cooling fan. The screen also displays the set
point for the cabinet fan to turn on and the temperature
threshold for triggering a high temperature alarm.
NTC Temperature Sensors
5.2.7
A screen is provided for each optional NTC sensor utilized
with the unit (up to four). These screens appear only if the
option is selected.
The NTC numbers coincide with the reference designators
that appear in the electrical drawing. These screens display
the current operating temperature measured by the sensor.
The screen also displays the set points for triggering a high
temperature and a low temperature alarm.
