Pairing
Failed
When first installed the startup Wizard will include
the pairing of the TPOne-S and the Receiver. If this
function was not completed correctly or failed due
to unreliable connection then this warning will be
shown. Manual pairing can be made by selecting
this option in the installer menu.
Important Note: Ensure that there are no large
metal objects, such as boiler cases, other large
appliances or mirrors in line of sight between
the transmitter and receiver as these will prevent
communication between the TPOne-S and
receiver.
