Two Zone AquaTimer

English/ Français/ Español

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

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

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.

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 for Immediate Watering

The Melnor Two Zone AquaTimer® Model 3100 is a device designed to automate lawn and garden watering across two separate areas, or "zones," each with its own programmable schedule. This allows for freedom and flexibility in managing watering tasks.

Function Description:

The AquaTimer® connects to an outdoor faucet via a coupler at the top of the unit. It features two valves, each controlled by a Frequency knob and a Duration knob, allowing independent programming for each zone. The Frequency knob sets how often watering occurs, with pre-set increments ranging from once an hour to once a week. The Duration knob determines how long each watering session lasts, with increments from one minute up to 120 minutes. Once programmed, the AquaTimer® will begin watering at the next scheduled cycle. For example, if programmed for a frequency of 12 hours, watering will start 12 hours after programming and continue every 12 hours thereafter.

The device also includes a "Now" feature, enabling immediate manual watering for a set duration without altering the programmed schedule. To use this, the Frequency knob is turned to "Now" and the Duration knob is set to the desired time. The valve will open and then automatically close after the specified duration.

A manual On/Off function is also available. Users can rotate the Duration knobs to the "On" position for manual watering and back to "Off" when complete. Rotating the Duration knobs to "Off" can also cancel a current program, useful for suspending watering due to rain, for instance. To resume the programmed time, the knobs must be rotated back to the desired Duration setting.

The AquaTimer® supports delayed watering for each zone by up to 12 hours using a small button at the bottom middle of each zone area. Each press of this button delays the first start time by one hour. The "Low Battery" light illuminates when the delay button is pressed.

Important Technical Specifications:

The AquaTimer® requires four AA alkaline batteries for operation. It is designed for outdoor use only, with clean water, and for residential applications. The device should not be exposed to temperatures at or below 32° F (0° C).

Usage Features:

Two Independent Zones: Allows for different watering schedules for two distinct areas.
Programmable Frequency: Users can select watering intervals from hourly to weekly.
Programmable Duration: Watering sessions can be set from 1 minute to 120 minutes.
Manual On/Off: Provides flexibility for immediate watering or program suspension.
"Now" Feature: Enables instant watering for a specified duration.
Delayed Watering: The first watering cycle can be delayed by up to 12 hours per zone.
Low Battery Indicator: A flashing light warns when battery charge is low, and valves close automatically to prevent overwatering.
Easy Programming: Knobs can be rotated in either direction for setting frequency and duration. Programming can be done whether the unit is attached or unattached to the faucet.

Maintenance Features:

Battery Replacement: Four fresh AA alkaline batteries are required. The battery door is located on the lower back of the unit. The device will cease operation until fresh batteries are installed.
Seasonal Battery Replacement: Batteries should be replaced at the beginning of each watering season.
Long-Term Storage: Batteries should be removed if the AquaTimer® will not be used for an extended period of time.
Filter Washer Cleaning: A filter washer inside the coupler at the top of the AquaTimer® should be cleaned regularly to prevent clogging.
Faucet Management: The faucet valve should be left open once the AquaTimer® is attached. If the AquaTimer® will not be used for an extended period, the faucet should be turned off.
Handling Precautions: To avoid damage to the faucet connection, users should not tug on a hose while it is attached to the AquaTimer®.

The AquaTimer® is designed to simplify garden and lawn care by providing reliable and customizable watering automation.
