4.3.1.1 Four Loop Mode
Four Loop mode provides a limited amount of information about each of the four sen-
sor inputs, and the associated control loops. Each quadrant of the display is dedicated
to one sensor input and the associated loop, if applicable. The top line of each quad-
rant contains the input letter (A, B, C, or D) followed by the user-assignable sensor
name. The sensor readings are presented just below the sensor name in the large
character format for easier viewing from a distance. The sensor reading is displayed in
the units assigned to the respective sensor input's Preferred Units setting, which can
be found under the Input Setup menu (section 4.4). If the input is assigned as the Con-
trol Input of a control loop, then the control Setpoint and Heater Output parameters
are displayed under the sensor reading. If the output is in Open Loop mode, then the
Setpoint parameter is not shown.
