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);
