*5
Initialized to control output (cooling) for heating and cooling control, according to the following.
(The defaults for standard control are the defaults in the parameter list.)
• With control output 2: The Control Output 2 Assignment parameter is initialized to control output (cooling).
• If the Digital Controller does not have control output 2 but has four auxiliary outputs, the Auxiliary Output 4
Assignment parameter is initialized to Control Output (Cooling).
• Otherwise, the Auxiliary Output 2 Assignment parameter is initialized to Control Output (Cooling).
*6
If the Program Pattern parameter is set to OFF, the Auxiliary Output 1 Assignment parameter is initialized as follows:
• Digital Controllers with HB and HS alarms: Heater alarm
• Digital Controllers without HB and HS alarms: Alarm 1
If the Program Pattern parameter is not set to OFF, the Auxiliary Output 1 Assignment parameter is initialized to the pro-
gram end output.
*7
If the Program Start parameter is assigned when the program pattern is changed to OFF, the Program Start parameter
will be initialized to "not assigned."
*8
The Integral/Derivative Time Unit parameter is initialized only when the RT parameter is turned ON. The default is as
follows:
• Integral/Derivative Time Unit: 0.1 s (The PID parameters are also initialized when the Integral/Derivative Time Unit
parameter is initialized.)
*9
This parameter is initialized to the new Password to Move to Protect Level password.
*10 These parameters are initialized when the Input Type parameter is changed from a temperature input to an analog input
or from an analog input to a temperature input.
*11 This parameter is initialized when the Input Type parameter is changed from a temperature input to an analog input or
from an analog input to a temperature input. However, it is not initialized if the applicable alarm is an MV absolute-value
upper-limit alarm or an MV absolute-value lower-limit alarm.
*12 This parameter is initialized to 50 (0.50%) if a non-MV alarm is changed to an MV alarm. This parameter is initialized to
2 (0.2°C or 0.02%FS) if an MV alarm is changed to a non-MV alarm.
*13 If the number of multi-SP points is decreased, the multi-SPs will be initialized to 0.
*14 The proportional band is initialized to 8.0 for a temperature input and to 10.0 for an analog input. (The same thing
applies to the cooling side.)
Integral time and derivative time are initialized as follows:
• Integral/Derivative Time Unit of 1 s: integral time to 233, and derivative time to 40. (This applies to both the heating
and cooling constants.)
• Integral/Derivative Time Unit of 0.1 s: integral time to 233.0, and derivative time to 40.0. (This applies to both the
heating and cooling constants.)
*15 If the temperature unit is changed, the value is converted to the new temperature unit.
*16 If all of the model parameters are not 0, they will be initialized for model parameter calculations. However, if any of the
model parameters is 0, they will be initialized to the defaults.
*17 If all of the model parameters are not 0, they will be initialized for model parameter calculations.
*18 Initialization is performed as shown below if the Control Output 1 Assignment parameter is set to a transfer output. The
initialization differs depending on the changed parameter and the transfer output setting.
• Transfer SP: SP upper and lower limits
• Transfer Ramp SP: SP upper and lower limits
• Transfer PV: Input setting range upper and lower limits or scaling upper and lower limits
• Transfer MV (Heating): 100.0/0.0
• Transfer MV (Cooling): 100.0/0.0
*18.1 Initialized only when the transfer output is set to Transfer SP, Transfer Ramp SP, or Transfer PV.
*18.2 Initialized only when the transfer output is set to Transfer MV (Heating) or Simple Transfer MV (Cooling).
*18.3 Initialized to the above default values regardless of the settings for changing the transfer output.
