+## Pairing
+
+Scan the qr code in the battery compartment to get the install code, which is needed for pairing. 
+Put your coordinator into pairing mode by using the 95 chars text string from the qr-code (see below).
+Reset the thermostat and put it into pairing mode by removing one battery and putting the battery back whilst pressing the front button.
+The thermostat should show **RES** after a short moment. Release the button and push it again until the led line indicator lights green.

 ## ZHA
 
-Call the Home Assistant service "zha.permit" with the device IEEE number and installcode from the cover. The zigbee interview works fine after.

+
+## Z2M
+
+You will need a coordinator that supports install codes in Z2M. zstack adapters do support this in Z2M. 
+If your adapter is not supported, you will get the message _Add install code is not supported_.
+
+See: https://github.com/Koenkk/zigbee2mqtt/issues/17492
+
+Use _Add install code_ in Z2M Tools menu to add the qr install-code and put Z2M into pairing mode.
