Climatix 6XX products are designed for use in ventilation, air conditioning, refrig-eration and district heating plants and provide a broad range of control and moni-toring functions. The product range is of modular design and primarily comprises controllers (ver-sions with or without HMI) and different add-on I/O modules, including step motor and factory- or field-mounted communication modules. Different HMIs can be con-nected to the controllers, either directly (local HMI) or via the network (remote HMI). The controllers are freely programmable.
The Climatix controllers are freely programmable with the help of a powerful SAPRO software tool, thus saving time and effort in air conditioning, ventilation and refrigeration application development and testing. A superior commissioning tool called SCOPE is also available free of charge. A number of defined inputs / outputs (analog or digital) plus freely programmable I/O channels make it possible to create a host of applications with or without addi-tional modules to meet specific requirements. In fact, on-board I/O functionality does not suffice, a peripheral bus allows for connecting further local and remote I/O extension modules. The number and type of I/Os on the controller and extension modules are opti-mized for air conditioning, ventilation and refrigeration applications. On-board communication interfaces round off this scalable and intelligent control system. Additional communication modules can be added to the system in accordance with integration requirements.
The controllers can be operated with or without HMI – with the same functional-ity. The Climatix 6XX controllers offer an inbuilt HMI or an external local HMI (typi-cally mounted on metal panels). In addition, a remote HMI is available, operating on the process bus, with power supply and communication over the same 2 wires (using KNX TP1 technology) to optimize installation costs.
The additional I/O extension product range for connection via the peripheral bus comprises different I/O extension modules, some of them also with programmable channel configuration. Specific modules for step motor control are also available via the peripheral bus.
Using extension I/O modules, it is easy to design units with certain main funtionali-ties provided by a controller plus extension I/Os, and then have extra functionalities by adding other extension I/O modules according to needs.
This flexibility in HW combinations also allows modularity of electrical panel design, supported by a suitable concept of mechanical properties, communication and power supply possibilities available on all extension I/O modules Additional communication modules (BACnet/IP, BACnet/MSTP, LON, MBus, Mod-bus RS-485 and advanced programmable Web modules) extend the connectivity options of Climatix controllers, aimed at matching integration interface require-ments, or to povide specific servicing choices.

Connecting the extension modules
Specification for pheripheral bus cable and power supply: • If the total length of the pheripheral bus cable exceeds 3 m, shielded cables
must be used (L1 + L2 + Lx = >3 m)
• If the total length of the pheripheral bus cable is less than 3 m, shielded cables are not required (L1 + L2 + Lx = <3 m)
• Each shield must be grounded at one side only • Maximum bus cable length is 30 m (L1 + L2 + Ln = <30 m) • To connect the bus cable to the modules, use the board-to-wire terminals • GND of the power supply must be grounded (see illustration above) • Connections from one plant to another can be effected via a 2-wire bus cable
(A+ and B-). In this case, the modules must be powered by a separate supply (see illustration above). All plants must have the same GND. GND of the power supply must be grounded at one point only
• Refer to the pass-through-current rules for limiting the current across each de-vice within the individual limits

Addressing the extension modules
The extension modules are equipped with DIP switches for communication with the controller. Switches 1, 2, 3, 4, and 5 are configurable to set the slave address, while switch 6 acts as peripheral bus termination. When the extension module op-erates as the termination in the network, switch 6 must be set to ON.
By combining switches 1, 2, 3, 4 or 5, a maximum of 31 slave addresses can be configured. Below are some configuration examples:

The same address of extension module must be set in the application program of the controller. Zero cannot be set as the slave address.
Connecting the extension modules
The pass-through current is the maximum current that can flow across each device to limit the current within the defined safety levels. When extension modules are powered by a controller or some other extension module over the peripheral bus lines, a calculation is necessary to make certain that the total apparent power for this group of devices does not exceed 96 VA. If this is the case, the group of controllers and extension modules must be subdi-vided into 2 subgroups, enabling each of them to draw less than 96 VA. Note: When using AC 24 V power supply, power consumption is higher than that resulting from DC 24 V, the reason being the better efficiency of DC power supply. As a result, with DC 24 V power supply, the number of extension modules that can be connected to the same power supply line is greater than with AC 24 V. Maximum number of extension modules 31 (1…31)
Maximun pass-through current per group 96 VA
Cable lengths Total of max. 30 m
Below are some examples that show a number of choices: The following table provides the maximal capacity of the controllers, considering the full load configuration for each device. For this reason, the values used in other configurations can be smaller than those stated here.
