FUNCTIONS
Control behaviour
•
Signaller with adjustable switching
differential (On/Off control)
•
PID controller (two-point and
continuous)
•
Delta / Star / Off, or two-point
controller with full/partial load
switchover
•
2 x PID control (Heating / Cooling,
three-point, and continuous)
•
Three-point stepping controller
Control parameters are adjusted auto-
matically (self-tuning) or manually via
the front panel or using the BlueCon-
trol
®
software package.
The KS 45 has been prepared for con-
necting PMATune, in order to determi-
ne the optimum control parameters,
also with difficult control loops.
Setpoint functions
•
Adjustable setpoint gradient
0.01...9,999 per minute
•
Setpoint control
•
Master/Slave control
•
Program control with 4 segments
(setpoint/segment times)
•
Timer
•
Setpoint/Program control with
external shift
Timer
