AXC 30 Expansion Card – Versatile Control Capabilities

The AXC 30 expansion card is a module that allows you to expand the functionality of the heating system with additional control options. It is a key element for installers and users who want to adapt the operation of the heat pump to individual needs and increase energy efficiency. This card allows you to connect and control various additional functions, such as auxiliary heaters controlled by a three-way or step valve.

Versatility and Flexibility

AXC 30 offers a wide range of configuration options, allowing integration with various elements of the heating installation. This makes it possible to precisely adapt the system to the specifics of the building and user preferences. This module is used both in new installations and in modernized heating systems.

Installation and Connection

The AXC 30 expansion card is mounted on the wall as a separate electrical module. Connection is made via the connection card (terminal AA100-X9) of the control module, and in the case of more accessories – in series. It is important to consult the operating instructions of the device when connecting accessories. The minimum cross-sectional area of communication and signal cables should be 0.5 mm² for lengths up to 50 m (e.g. EKKX, LiYY).

Safety of Use

The relay contacts on the expansion card have a maximum load of 2 A (230 V), ensuring safe operation of the system. The DIP switch (S2) on the AXC 30 card allows configuration of settings according to the requirements of the installation. In addition, the card has an overcurrent switch (AA25-FC1) to protect against overloads.
