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 step1: 10 %
Stop step1: 5 %
Start step2: 45 %
Stop step2: 40 %
Start step3: 70 %
Stop step3: 65 %
Start step4: 95 %
Stop step4: 90 %
Control parameters. Heater groups is used to calculate activation levels for binary control.
"Hyst." is the switching differential used for each step when running binary control.
Nbr of steps: 4
Minimum on/off
time: 60 s
Hyst: 0.5 %
17.25.2 Step controller cooling
"Step controller Cooling" can be set to sequential or binary.
Step contr. cooling
Sequential 
"Step controller Cooling" 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: 50 %
Stop step 2: 45 %
Start step 3: 95 %
Stop step 3: 90 %
Control parameters. Chiller groups is used to calculate activation levels for binary control.
“Hyst.” is the switching differential used for each step when running binary control.
Nbr of steps: 3
Minimum on/off-
time: 60 sec
Hyst: 0.5 %
When DX cooling is used in conjunction with pressure controlled or flow controlled fans it is
possible to block DX cooling if the supply air fan control signal falls below a preset values.
The blocking level is individually settable for each DX cooling step.
At lower SAF output
block step1: 0 %
block step2: 0 %
block step3: 0 %
