LCD SCREEN BACKLIGHT
The LCD backlight can be turned on or off.
To turn the light off press and hold down the (˅) button. Press and release
the (R) button. Release the (˅) button. Repeat to turn the light on. The
light remembers the state it was last left in, if power is turned off. The light
can be left permanently on or off as required.
TEMPERATURE
The E30 monitors its internal temperature when running. Pressing the
(˅) button while the controller is operating normally displays the current
internal temperature.
PRESS (and release) THE (P) BUTTON
When the E30 is powered up, pressing the (P) button, holding it down
for 1 second and releasing it takes you to the top of the menu. Pressing
and releasing the (P) button loads whatever the screen is displaying into
the E30’s memory. The memory is non-volatile and settings are retained
when power is off. You can exit the menu at any time by pressing and
releasing the (R) button. Any settings you have made up to that point will
be retained. There is no need to step all the way through the menu when
making a change to a setting.
INSTALLING THE E30
1) Do not install the E30 in a fully exposed outdoor location. The E30
is weatherproof, however, to ensure a long reliable life, we recommend
it be protected from direct exposure to the sun and rain. A skull cap
is provided with the E30 and we recommend it be used to protect the
E30 when direct observation of the LCD screen is not required.
2) Do not expose the E30 to freezing. If the pipework in which the
E30 is installed freezes, the pressure sensor in the E30 may fail. If the
E30 is to be used in areas where low temperatures will be encountered,
always lag the pipework for several metres either side of the E30.
Also lag the base of the E30 to prevent the unit and any adjacent
pipework from freezing.
3) Do not use this controller in hot water applications. The E30 is not
designed to be used in water hotter than 60ºC.
