Pool’nX: control the pool from KNX (filtration, lighting, pump)

The Pool Commands table of Pool’nX maps each command of the Klereo or PoolCop controller to a KNX group address: filtration, lighting, pump, valve, auxiliaries, heating setpoint. When a write telegram arrives on the address, Pool’nX converts the value and sends the command to the controller.

Intended for the installer who controls the pool from a KNX push button, visualization or logic. The accepted values depend on the controller: see the Klereo table or the PoolCop table.

Before you start

• The type of pool, the credentials and the pool are chosen: see open Pool’nX in Can’nX Cloud.
• In ETS, the sending KNX object writes to the group address with the DPT of the row, shown in the DPT column.

Map a command

1. In the Pool’nX window, next to Pool Commands, click the double-arrow button.
2. The table shows Name, Value, Last event, DPT, KNX Group Address and Active.
3. Find the command with Search by name.
4. Enter the group address in X/Y/Z format, for example 5/2/0 (example), and tick Active.
5. Remove the filters: only the displayed rows are saved.
6. Click Save. Success! confirms the save.

Auto-fill addresses and Clean all addresses work as in the status table.

Pool’nX executes any command whose row has an address, whether the Active box is ticked or not. The box is used by the filter and by the ETS export. To stop an address from controlling the pool, clear it from the row, then save.

Use a different address for each command: if two rows have the same address, only the first one is executed. A read request on the address sends no command.

Read Value and Last event

• Last event: date and time of the last telegram received for this command.
• Value: last value received from the bus. With Klereo, it is shown with its meaning, for example Manual Mode: On (1).

When the command did not succeed, Value shows a message instead of the value:

Message	Controller	Meaning
invalid followed by the value	Klereo	Value not accepted for this output: nothing is sent.
reserved aux	PoolCop Cloud	Auxiliary reserved by the PoolCop: on and off are refused.
no heating aux configured	PoolCop Cloud	No auxiliary controls heating.
PoolCop refused followed by a code	PoolCop Cloud	PoolCop Cloud refused the command.
PoolCop unreachable	PoolCop Cloud	PoolCop Cloud did not respond.
invalid value or aux id	PoolCop (legacy)	Unreadable value or no heating auxiliary.

A value displayed without a message means that Pool’nX received it. Some out-of-range values are not passed on and show no message: check the effect in the statuses.

Check the result

1. Send the command from the visualization, or write the value to the address with the ETS group monitor.
2. Check that Last event and Value are updated.
3. Open Pool Status: the matching state changes once the controller has taken the command into account. With PoolCop Cloud, allow up to about two minutes.
4. Watch the pool equipment.

Troubleshooting

Symptom	Cause and action
Last event does not change	No write telegram received on the address. Check the address entered, that the table was saved, and the address used by the KNX sender.
A command is sent although Active is unticked	The row still has an address. Clear it and save.
Message in Value	See the table above and the controller values.
Status unchanged after the command	The controller has not confirmed yet, or its operating mode takes precedence. Check the state in the controller’s app.
