Cooling Coefficient (Display Level 1)
PV
SV
Cooling coefficient parameter symbol
Cooling coefficient of currently selected loop
•
This sets the coefficient for finding the cooling P constant. It is valid when
SW203-1 is OFF (PID control). The formula for calculating the cooling P
constant is as follows:
Cooling P constant = heating P constant x cooling coefficient
•
The I/D constant is the same for cooling as for heating.
Control Period (Display Level 1)
PV
SV
Heating control period parameter symbol
Heating control period of currently selected loop
(Unit: seconds)
PV
SV
Cooling control period parameter symbol
Cooling control period of currently selected loop
(Unit: seconds)
•
This sets the control period. It is valid when SW203-1 is OFF (PID control), and
only when the heater model is not the C200H-TV
03 (current output type).
•
Cooling loop 1 is invalid when SW203-6 is ON (current output).
•
The control period is the time required to complete one transistor output or volt-
age output ON/OFF cycle.

Hysteresis (Display Level 1)
PV
SV
Hysteresis parameter symbol
Hysteresis of currently selected bank and loop
(Unit:
°
C or
°
F)
•
Hysteresis prevents control output chattering and eliminates noise influences.
•
When switching from ON to OFF, operation proceeds at the set point. When
switching from OFF to ON, operation proceeds at a lower point determined by
the hysteresis SV, as shown in the following illustration.
