DIGISTAT
INSTALLATION
DIGISTAT / DT20RF RECEIVER
SETTING UP THE RF LINK
6. Remove the batteries from the Digistat and wait
for the display to fade.
7 Press and hold the ‘SET’ button while re-inserting
the batteries and keep the button depressed until
the display shows ‘rF’.
The Digistat is now in constant transmission mode
enabling it to be correctly positioned within the
home.
8. The receiver display will now show the ‘learnt’
transmitter code and the antenna’ as well as the
signal strength as indicated by the chevrons on
the left hand side of the display.
9. Place the transmitter in the desired final position
and return to the boiler to check the receiver
display. The ideal transmitter position will result in
the receiver display showing 4 chevrons and the
LED will be green.
9. If the LED is red or no LED is showing and the
display indicates 1 or 2 chevrons, the transmitter
will need to be re-positioned until the LED
changes to amber or green and 3 or 4 chevrons
are indicated on the display.
NOTE: If there is no LED and the display shows
‘- - -’, there is no signal being received at all from
the transmitter. Transmission will resume once the
transmitter is re-positioned in a part of the house
where an amber or green LED and 3 or 4
chevrons are achieved.
10. Once you are happy that, when in the desired
location, the transmitter is sending a good signal
to the receiver i.e. amber or green and 3 or 4
chevrons, the transmitter can be fixed to the wall.
