Appendix
Note (1) Initialized to input setting range upper and lower limits, or scaling upper and lower limits.
(2) Clamped by SP upper and lower limits.
(3) Initialized only when the input type is changed to analog input when RT turns ON. The defaults are
as follows:
RT: OFF
Proportional band: 8.0
Integral time: 233
Derivative time: 40
(4) Initialization is performed as shown below according to the transfer output type setting. The initial-
ization differs depending on the changed parameter and the output type setting.
SP: SP upper and lower limits
Ramp SP: SP upper and lower limits
PV: Input setting range upper and lower limits or scaling upper and lower limits
MV (Heating): 100.0/0.0
MV (Cooling): 100.0/0.0
(4-1) Initialized only when the transfer output type is set to SP, Ramp SP, or PV.
(4-2) Initialized only when the transfer output type is set to MV (Heating) or MV (Cooling).
