[TP-65] Pairing (Re-syncing) Follow
How do I connect my TP65?
If you can't see the OUT reading on your display unit, you may need to pair or re-sync your device with the remote sensor. Please follow this step:
With both units side by side, take the batteries out of both units. Once this is done, you can put the batteries into the indoor unit first. Then, you'll have 3 minutes to put the batteries into the remote sensor.
If this is unsuccessful, please try these steps again with a new set of batteries.
Note: If more than 3 minutes have elapsed from the time you put the batteries
into the indoor unit and you haven't put the batteries into the remote sensor
you may have to repeat the pairing process.
