2. Regulation Mode: Set the control parameters
LED Display Explanation Default
AT: Auto-tuning setting. When AT key is set to ON ( ), the execution of the PID auto-tuning function is automatically started.
(PID control)
OFF
P: Proportional Band (PID control) 47.6
I: Integral Time (PID control) 260
D: Derivative Time (PID control) 41
PdoF: Offset output when P or PD control function is ON. (PID control and Ki=0) 0
ioF: Default value of integral volume when PID control function is ON and integral time constant is not equal to 0(zero). AT can
automatically set this parameter. (PID control and Ki≠0)
0
HTS: Set Heating hysteresis when ON/OFF control function is ON. 0
CTS: Set Cooling hysteresis when ON/OFF control function is ON. 0
HTPD: PID heating control cycle setting (PID control)
CLPD: PID cooling control cycle setting (PID control)
Output Selection:
V: 4 sec.
R: 20 sec.
TPOF: Regulate temperature deviation value 0
CRHI: Regulate 20mA output deviation value 0
CRLO: Regulate 4mA output deviation value 0
3. Initial Setting Mode: Initial settings of the controller and communication parameters
LED Display Explanation Default
INPUT: Select input temperature sensor type (Please refer to the contents of the “Temperature Sensor Type and Temperature
Range” for detail)

T-HIGH: Upper limit for temperature range 500.0
T-LOW: Lower limit for temperature range -20.0
CONTROL: Control method setting on the SV display: PID ( ), ON/OFF control ( ), or manual tuning ( )
PID
SWITCH: Select Heating ( ) or Cooling ( ) action
HEAT
AL1 SET: Alarm 1 setting 0
AL2 SET: Alarm 2 setting 0
C WE: Write-in function disable/enable (Displayed when using serial communication) OFF
C NO: Address setting (Displayed when using serial communication) 1
BPS: Baud rate setting (Displayed when using serial communication) 9600
LENGTH: Data length setting (Displayed when using serial communication) 7
PARITY: Parity bit setting (Displayed when using serial communication) E
STOP BIT: Stop bit setting (Displayed when using serial communication) 1
Note: Alarm values should be set in the initial setting mode so AL1H, AL1L, AL2H and AL2L would display in operation mode.
 Heating and Cooling Control
Temperature control is achieved either by heating or by cooling. The heating function starts when the process temperature (PV) is going down, and the cooling
function when the temperature is getting high. It is impossible to operate both functions simultaneously in this controller.
