Two circuits / Multi-circuit
These devices have two to max. four hydraulically separated circuits that are installed either in one
or in two separate, lamellar heat exchangers. As a result, each circuit has a separate pressure or
temperature sensor.
Max. selection
This function relates to two or more circuit devices that work with only one internal controller and
several sensors. The circuit with the higher value on the sensor (pressure or temperature) is
determined as the control variable in the TCS and thus the regulating variable (fan speed).
Separate control:
Both lines of a two-circuit device are not only considered hydraulically but also separately in terms of
control technology. As a result, there are also two internal controllers whose control variable
addresses two different fan groups. Two different refrigerants or heat carriers are possible.
Selection of device design
Also, this function is shown in white and cannot be changed by the customer (manufacturer password
required). The following device designs can be selected from the factory. These are shown as
examples during the selection and on the start screen.
1. Table cooler horizontal single row
2. Table cooler horizontal double row
3. Table cooler vertical single row
4. Table cooler vertical double row
5. Double block cooler V-shape single row
6. Double block cooler V-shape double row
Load factory settings
After selecting the heating system, the factory settings must be loaded during commissioning. The
system sets all device-specific standard settings, setpoints and configures the inputs and outputs.
Attention! All previously made parameter adjustments and customer settings are lost. A prior
comparison of the set parameters with the parameter list on the circuit diagram is essential!
