AJAX Relay User Manual

For detection and pairing to occur, the device should be located in the coverage
area of the hub’s wireless network (at the same object). The connection request
is transmitted only at the moment of switching on the device.
If the device failed to pair, wait 30 seconds and then retry. Relay will appear in
the list of hub devices.
The device statuses update depends on the ping interval set in the hub settings.
The default value is 36 seconds.
When switching on for the first time, Relay contacts are open! When deleting Relay from
the system, contacts open!
