Binary Control
Each loop has three reverse- (heating) and three direct- (cooling) acting binary sequences. The offset to the setpoint is
adjustable for each sequence. The switching hysteresis is adjustable per control loop.
Action of stages: The stages may be activated according three different patterns:
One at the time: Only one stage is active at the time. The lower stage will be switched off when the higher stage gets
active. Example: fan speed control.
Cumulative: Multiple stages are active at the same time: The lower stage stays activated when the higher stage
switches on. Example: Electrical heating stages
Binary coded: In the first step only the first stage is active; in the second step only the second stage. In the third
step both stage 1 and stage 2 are switched on. This is used for heating stages. The size of the
second heating stage should be doubled the size of the first heating stage. For example 100W for the
first stage and 200W for the second stage. With two outputs we could create the following steps: 1.
Step 100W, 2. step 200W, 3. step 300W.

Switching Hysteresis: Defines the difference between switching on and switching off of a digital sequence. A small
hysteresis will increase the number of switching cycles and thus the wear on associated equipment.
Delayed switching. Cumulative Heating/ cooling stages will not switch simultaneously with stage 1, in case of a sudden
demand or at power on. Stage 2 will not start earlier than 5 seconds after stage 1 has been initiated.
