Congratulations on the purchase of your new Melnor Two
Zone AquaTimer®! The Melnor Two Zone AquaTimer® will
allow you freedom and flexibility in watering your lawn and
garden.

Battery Installation

Before you begin using your Melnor Two Zone AquaTimer®,
you will need to install four AA batteries. On the lower back
of your AquaTimer® is a small battery door with a tab. Push
down on the tab and the door will slide off easily. Pull out
the black battery holder that is inside the unit. Insert four AA
batteries into the battery holder. Push the battery holder back
into the unit and snap the battery door securely into place. As
soon as the batteries are in the holder, you will hear the valves
activate.

There is a small light at the bottom center of your AquaTimer®,
under which are written the words “Low Battery”. The Low
Battery light will flash when the charge in the batteries is
low, and the valve(s) will close automatically, preventing over
watering. The timer will cease operation until fresh batteries
are installed.

Programming Your AquaTimer

circle surrounding the knob that
represents the length of time
for which you want the water
to run. You have now set the
duration of Zone 1.

Your AquaTimer will begin watering
with the next scheduled watering cycle. Example: If you
program the Frequency to 12, the AquaTimer will begin
watering 12 hours after you program it and every 12 hours
after that.

To program Zone 2, follow the same two steps that you have
just completed for Zone 1. The two zones can be set for
different frequencies and durations.

Your AquaTimer® can be programmed while it is either
attached or unattached to the faucet.

Installing the AquaTimer

At the top of your AquaTimer® is what is known as a
“coupler”. Use the coupler to attach your timer to the outdoor
faucet. Once you have attached the AquaTimer® to the
faucet, open the faucet valve and leave it open.

At the bottom of your AquaTimer, there are two connectors
onto which you can attach two hoses.

®

Your Melnor Two Zone AquaTimer® has two valves, which
makes it possible for you to automatically water two separate
areas (or “zones”) of your lawn or garden on two different
watering schedules. Each zone is controlled by a Frequency
knob and a Duration knob. The knobs can be rotated in either
direction.

Each zone can be programmed independently. The first step
is to set the watering frequency (How often do you want to
water?). There are pre-set timing increments on the unit’s
Frequency knob from as often as once an hour to as little
as once a week. Turn the yellow Frequency knob for Zone
1 and line up its arrow with the number on the green circle
surrounding the knob that represents your desired watering
frequency. You have just set the frequency of Zone 1.

The second step in programming your AquaTimer® is setting
the Duration (How long do you want to water?). There are
pre-set increments on the unit’s Duration knob starting with
one minute per watering session going up to as long as 120
minutes per session. Turn the yellow Duration knob for Zone
1 so that its arrow is lined up with the number on the green

Manual On/Off

Your Melnor Two Zone AquaTimer® allows you to water
manually without removing your AquaTimer® from the faucet.
To turn on your AquaTimer®, simply rotate the desired
Duration knobs to the On position. Turn it back to the Off
position when the watering is complete. You also can
rotate the Duration knobs to the Off position if you want to
cancel the current program. You might want to suspend the
program if it rains, for example. If you do that, you will need
to rotate the knobs back to the desired Duration to resume
its programmed time.

Now Feature

If you would like to water immediately for a set amount of
time, your AquaTimer® can help. Turn the Frequency knob to
“Now” and then set the Duration knob to indicate how long
you want the water to run. For example, if you want to water
your lawn or garden immediately and want the water to run for
three minutes, turn the Frequency knob to Now and turn the
Duration knob to 3. The valve will open and then automatically
close after three minutes.

Modelo 3100 - Reloj automático para riego en
dos zonas “Aqua Timer” de Melnor

¡Felicitaciones por la compra de su nuevo reloj automático
para riego en dos zonas “Aqua Timer” de Melnor! El reloj
automático para riego en dos zonas “Aqua Timer” de Melnor
le brindará libertad y flexibilidad para regar su parque y jardín.

Instalación de las baterías

Antes de comenzar a utilizar su reloj automático para riego
en dos zonas “Aqua Timer” de Melnor, usted necesitará
instalar cuatro baterías AA. En la parte posterior e inferior de
su “Aqua Timer” hay una pequeña puerta para las baterías,
que tiene una aleta. Presione la aleta hacia abajo y la puerta
saldrá deslizándose fácilmente. Quite el sostén negro para
las baterías, que se encuentra dentro de la unidad. Inserte
cuatro baterías AA dentro de dicho sostén. Presione el sostén
de las baterías hacia adentro de la unidad y cierre la puerta a
presión, afirmándola en su lugar. Tan pronto como las baterías
se encuentren en el sostén, usted oirá a las válvulas activarse.

Delayed Watering

You can delay the first watering cycle of each watering zone
by up to 12 hours by using the small button at the bottom
middle of each zone area. Press the delay button 1 time for
each hour you wish to delay the first start time. The “Low
Battery” light will illuminate when you press the button. The
maximum delay is 12 hours.

For example, if you are programming at 4:00 in the afternoon
and you want your timer to water every 12 hours, but you
want the first watering of the day to start at 6:00 a.m., press
the Delay button two times. Without the delay, the first cycle
would have occurred 12 hours after the timer is programmed
(4:00 a.m.). The delay feature changes that to 6:00 a.m. The
timer will then water every 12 hours after that.

Hay una pequeña luz en la parte inferior central de su “Aqua
Timer”, debajo de la cual están escritas las palabras “Low
Battery” (baterías con baja carga). La luz de las baterías
descargadas centelleará cuando la carga de las mismas esté
