Submenu
PID
The PID submenu also lets you:
• set the Soft-Start time (parameter SOFT.T, default =
0.0);
• select the type of Auto-Tuning used (parameter Aut.t,
default = CONTI);
• set the derivative time (parameter DERV.S, default = 1);
• set the proportional heating band or hysteresis in ON-
OFF control (parameter H.PB, default = 1.0);
• set the integral heating time (parameter H.IT, default =
4.00);
• set the derivative heating time (parameter H.DT, defau-
lt = 1.00);
• set the maximum heating power limit (parameter
H.P.HI, default = 100.0);
• set the minimum heating power limit (parameter
H.P.LO, default = 0.0);
• select the cooling fluid (parameter COOL, default =
FAN);
• set the cooling setpoint compared to the heating
setpoint (parameter C.SP, default = 0.0);
• set the proportional cooling band or hysteresis in ON-
OFF control (parameter C.PB, default = 1.0);
• set the integral cooling time (parameter C.IT = 4.00);
• set the derivative cooling time (parameter C.DT = 1.00);
• set the maximum cooling power limit (parameter
C.P.HI, default = 100.0);
• set the minimum cooling power limit (parameter
C.P.LO, default = 0.0);
• set the Manual Reset value (parameter RESET, default
= 0);
• set the Reset Power value (parameter P.RST, default =
0.0);
• set the Antireset value (parameter A.RST, default = 0);
• set the Feedforward Power value (parameter, default =
0.0);
• set the deadband (parameter DEAD.B, default = 0);
• set the fault action power (parameter FAULT, default =
0.0);
• set the setpoint gradient in raise (parameter GRAD.I,
default = 0.0);
• set the setpoint gradient in lower (parameter GRAD.D,
default = 0.0);
• select the gradient unit of measurement (parameter
Unit, default = DIG/S);
• set the control output gradient (parameter GRAD.O,
dafault = 0.0);
