PID CONTROL TYPE
HEAt COOL botH
Select the type of PID control desired. When programmed for
Heating action (reverse), the output power decreases when the
Process Value is above the setpoint value. When programmed for
Cooling (direct), the output power will increase if the Process value
is above the Setpoint Value.
PID CONTROL MODE
Auto MAN
Select Automatic or Manual Operation. In Automatic (Auto) mode
(closed loop; On/Off, or PID Control), the controller calculates the
required output to reach and maintain setpoint, and acts accordingly.
In manual mode (MAN), the calculated PID algorithm heat and cool
output percentages are not used to control the controller outputs. The
unit is instead placed into an open loop mode where the control does not work
from a setpoint or process feedback.
The following programming step is only available when PID Control Mode
is set to Manual Mode (MAN).
OUTPUT POWER
-100.0 to 100.0 %
Manual Output Power is the level the PID module will assume in
manual mode.
