Wire it, add it to Can’nX Cloud, connect Klereo or PoolCop and map its KNX group addresses, step by step and in the right order. canonical: https://wiki.can-nx.com/en/demarrer/poolnx/ language: en --- # I bought a Pool’nX: step-by-step commissioning A new Pool’nX is commissioned in eight steps, from the electrical cabinet to the KNX bus: wiring, adding it to Can’nX Cloud, connecting the Klereo or PoolCop controller, then mapping statuses and commands to KNX group addresses. Follow them in order: each guide ends with a link to the next step. ## Before you start - Room for 2 modules on a DIN rail, in a watertight cabinet, and a 9-30 V DC power supply of at least 2 W. - An RJ45 cable to a switch or the Internet box, with Internet access. - A Can’nX Cloud account allowed to create a project and add a gateway to it. - For a Klereo pool, the username and password of a Klereo Connect account that sees the pool. For a PoolCop, access to the PoolCop account to generate an API key. - The ETS project of the installation, where the pool’s group addresses will be created. ## Commission the Pool’nX, step by step 1. [Wire the gateway](https://wiki.can-nx.com/en/guides/pool-install-wiring/) to the KNX bus, the power supply and the Ethernet network. Note the MAC address and serial number before closing the cabinet. 2. [Add it to a Can’nX Cloud project](https://wiki.can-nx.com/en/guides/pool-install-cloud/) with its QR code, or with its MAC address and serial number, then start its initialization: about ten minutes, with the gateway powered and connected to the Internet. 3. [Open the Pool’nX window](https://wiki.can-nx.com/en/guides/pool-access/) from the gateway page and find its settings. 4. Connect the pool controller: [Klereo, with the Klereo Connect credentials](https://wiki.can-nx.com/en/guides/pool-klereo-connect/), or [PoolCop, with a PoolCop Cloud API key](https://wiki.can-nx.com/en/guides/pool-poolcop-connect/). Choose the right type of pool from the start: changing it erases the whole configuration. 5. [Send the statuses on the KNX bus](https://wiki.can-nx.com/en/guides/pool-knx-status/): one group address per measurement or state, with the DPT set by Pool’nX. The values of each controller are in [the Klereo table](https://wiki.can-nx.com/en/guides/pool-klereo-knx/) and [the PoolCop table](https://wiki.can-nx.com/en/guides/pool-poolcop-knx/). 6. [Map the commands](https://wiki.can-nx.com/en/guides/pool-knx-commands/) the pool receives from the KNX bus: filtration, lighting, pump, valve, auxiliaries, heating setpoint. 7. [Export the addresses to ETS](https://wiki.can-nx.com/en/guides/pool-knx-ets-export/) as a CSV file, import it into the ETS project, then link the addresses to the objects of the KNX devices and program them. 8. [Set the options](https://wiki.can-nx.com/en/guides/pool-options/): periodic status sending or on request via KNX, and a watchdog sent every minute. ## Check the commissioning - In the project’s gateway list, the icon in the **Online** column is green. - In the **Pool Status** table, **Live values** is followed by a green dot. - A command sent from the bus updates **Last event**, then the matching state in **Pool Status**. With PoolCop Cloud, allow up to about two minutes. Then watch the pool equipment. ## Depending on your installation - [Control the water temperature](https://wiki.can-nx.com/en/guides/pool-temperature-control/) by hysteresis, with a KNX sensor and actuator. - [Connect a non-KNX supervisor](https://wiki.can-nx.com/en/guides/pool-tcp-client/) over TCP, port 50000. - On site, [the local configuration site](https://wiki.can-nx.com/en/guides/pool-local-config/) sets the IP address, DHCP, time server and credentials. It also gives access to [KNX-IP and the address tables](https://wiki.can-nx.com/en/guides/pool-local-knxip/) and to [the group monitor](https://wiki.can-nx.com/en/guides/pool-local-monitoring/). ## Troubleshooting For an offline gateway or an abnormal LED, see [Pool’nX wiring](https://wiki.can-nx.com/en/guides/pool-install-wiring/). [Pool’nX questions and troubleshooting](https://wiki.can-nx.com/en/guides/pool-help/) answers the other frequent cases: greyed-out button, empty pool list, PoolCop key rejected, status missing from the bus, command with no effect.
