The display counts down for a period of 10 minutes, with the RF Signal indicator flashing while the signal is being
transmitted. The RF address code will be generated randomly.
When the Boiler Control successfully receives a signal from the ST620 during the pairing operation, the Boiler Control
will store the generated address code into its internal memory. The LED will pulse once every second and go out if the
code is stored correctly, or pulse twice every second if this was unsuccessful. If pairing is unsuccessful then you will have
to re-start the pairing process.
Additional Information
Pressing the Reset button on the ST620 will clear the RF address code and restore the default code which will be saved
into the internal memory of the unit. Replacing the ST620 batteries will not affect the RF code setting, pressing and
holding the SYNC button on the Boiler Control will however clear the RF address code saved into the internal memory,
and switch the Boiler Control into pairing mode, as previously described.
