16.23.1 Step controller heating
Step controller Heating can be set to sequential or binary.
Step contr. heating
Sequential
Step controller Heating activation levels for sequential control.
For binary control the activation levels are calculated by the controller depending on the
number of steps involved
Start step 1: 10 %
Stop step 1: 5 %
Start step 2: 45 %
Stop step 2: 40 %
Start step 3: 70 %
Stop step 3: 65 %
Start step 4: 95 %
Stop step 4: 90 %
Control parameters. Number of groups is used to calculate activation levels for binary
control. Hyst is the switching differential used for each step when running binary control.
Chiller groups: 4
Minimum on/off-
time: 60 sec
Hyst: 0.5 %
