Part 2 - System overview
Introduction
Thank you for buying a Harvst WaterMate - this guide will walk you through the
concepts, modes of operation, and how to install the system.
WaterMate is a complete kit of parts; containing everything you need to set up
automatic irrigation.
WaterMate comes in two sizes:
Mini
Pro
Designed for smaller greenhouses, up to
6m2 of watered area.
The Pro kit comes with a more powerful
pump, and more pipework, for larger
greenhouses and polytunnels, up to
40m2 of watered area.
There are three power options:
Solar
Mains
4-season
Powered by a solar panel,
or plugged in using a
mains charger for
additional watering time
throughout the year when
there may not be as much
sunshine, or if your
location does not get
much sun.
Powered by a 240v power
supply, for installations
which require heavy duty
watering or have no sun.
As per the mains version,
with 3 additional power
outputs for extra pumps,
grow lights or low voltage
heaters. Powered by a
240v power supply.

Control unit
The brains of the system, it controls the pumps and valves.
●Timer - from twice a day, to once every 5 days. A straightforward timer routine
is a good baseline to work with. As the seasons change, update your program.
●Temperature - Choose to water more when itʼs hot, or less when itʼs cold.
Settings and control
Settings are managed on a smartphone, tablet or laptop. If the control box is within
range of home WiFi, you can also monitor and control your system from anywhere that
has an internet connection. Read more about the control unit, and how to manage
settings, in Part 3 of this guide
Dual zone valves
Watering can be managed in two separate zones via an electric water valve, depending
on whatʼs growing in each zone. You might want misters or sprayers for seedlings on
greenhouse staging, and drippers for larger plants such as tomatoes or peppers. Or, you
can water your two zones based on how much water they need; a dryer zone for one
plant and a wetter zone for another.
Water supply
Garden hose
Feed directly into the
water valves. Leave the
hose tap turned on and
Watermate will manage
the rest.
Mini pump
A submersible pump
capable of providing
water for small
greenhouses.
Pro pump
An inline pump capable of
providing larger amounts of
water at a high pressure, for
larger greenhouses and
polytunnels.
Irrigation parts
Supplied with the Watermate are a range of pipes, hoses and fittings for you to install
into your own greenhouse or polytunnel. See how to install the valves, pump and other
components in Part 4 of this guide.

Part 3 - The control unit
Solar powered systems
Solar powered control boxes have a built-in battery, which must be kept charged using
the solar panel. As soon as you receive your WaterMate system, plug in the solar panel
and put it in a sunny location so that the battery is fully charged when you come to set
up and test.
The solar panel must be plugged in at all times, to keep the battery in good condition.
The solar panel should be mounted outside the greenhouse or polytunnel; try to
position it so that it catches the most sun possible.
The built-in battery will provide enough power for up to ten minutes of watering per
day, and will recharge fully on a sunny summer day; more than enough for most
greenhouses and polytunnels.
Charging will be disabled below 5°C or above 45°C to ensure a long battery life. If
possible, do not mount the control unit in full sun, so that you get more charging time
in the summer.
8
Power saving (sleep)
The control unit will go to sleep when it is not doing anything, to save battery power. It
wakes up every 30 minutes to take readings, and to turn on the water pump if required.
To change settings, or override the watering, the control box needs to be awake.
To wake the unit up press the override button on the top until you hear a rising tone.
Winter commissioning
When you set up your system for the first time, youʼll want to run the pump to test your
pipes and fittings. This will probably run the battery down - when the battery is low,
you will hear a falling tone from the control unit and the pump wonʼt run for long, if at
all.
In the winter, with overcast skies and a low sun, your battery may not recharge fully
within a few days. You can either wait until you have more sun, or you can buy a top-up
/ trickle charger to take the place of the solar panel over winter.
