CHECKING THE RF SIGNAL STRENGTH (Model HERO-375 Only)
After the Hydrolink
™
RO Module has been added to
the remote, it is useful to check the signal strength on
the remote:
1.
Have the remote in its intended location.
2.
Press the remote’s RIGHT (
) or LEFT (
) buttons
to advance to the status screen for the HERO-375.
3.
With the HERO-375 status screen displayed, press
the SELECT (
) button to display the HERO-375 menu.
4.
Press the DOWN (
) button to scroll through the
menu options until
RF signal strength
is highlighted in
a box (as shown below).
5.
Press the SELECT (
) button, and the screen
shown below will appear. The more bars that are filled
in black, the stronger the signal. The signal strength
display updates every 15 seconds.
6.
To exit this screen, press the LEFT (
) button.
If the signal strength is weak (2 bars or less on the dis-
play), check the RF signal strength of the softener. As
described on Page 14 (Hydrolink
™
Communication
System), during normal operation the RO communi-
cates indirectly with the remote, using the softener to
relay information. Checking the signal between the
softener and remote may help to identify which is the
“weak link” in the chain.
Check the softener’s RF signal strength by going back
to the rolling status screens, advancing to the softener
status screen, pressing SELECT (
) and repeating steps
4 and 5. Since the RO communicates with the remote
through the softener, the link between the softener and
remote may be the weak one. Remedies for low signal
strength include moving the remote to a different loca-
tion and checking again.
If the signal strength of the RO is very weak compared
with the softener’s signal, it may be necessary to take
the Hydrolink
™
RO Module out from under the RO
system cover and mount it to the wall vertically (See
Figure 15) There is a recess on the back of the module
for hanging it from a fastener (not included).
