Holman EVIE WX8RS User Manual

INTRODUCTION
Your EVIE Sensor communicates to the WX8 to automatically disable your
watering schedules after 5mm of rain, reducing your water usage in the process.
The sensor uses two electrodes (A) connected
to a Radio Frequency (RF) Transmitter.
When water begins to fill the sensor, the circuit between the two electrodes
completes, and the RF Transmitter can wirelessly communicate to the WX8
to stop watering. After the water in the sensor evaporates, the circuit is once
again disconnected, and the RF Transmitter tells the WX8 it can continue with
your watering schedules. The sensor holds a maximum of 25mm of rainfall.
Your EVIE Sensor regulates how quickly watering will resume
after rain. This comes from the amount of rainfall collected,
and how quickly it evaporates in heat or wind.
ΠWhen water fills above the internal electrodes (A), the
EVIE Sensor will detect the moisture and any automatic
watering starts will be disabled in Holman Home
ΠAs the water evaporates and the water level drops below the centre weir (B),
the sensor will report back to your WX8 as dry, and any automatic watering
starts will be reinstated in Holman Home
PAIRING TO THE WX8 IRRIGATION CONTROLLER
ΠYour EVIE Sensor should
already be paired with your
WX8 Irrigation Controller
1. Check the DEVICE INFORMATION (C)
page in Holman Home to ensure
your EVIE Sensor is paired
to the WX8 correctly and the
battery is in good condition
2. If your EVIE Sensor does not appear
to be paired to your WX8, please see
our pairing instructions overleaf

INSTALLATION
ΠTo communicate to the WX8 Irrigation Controller, the
EVIE Sensor needs to be installed no more than 20 metres
from the controller with a clear line of sight
D
ΠThe EVIE Sensor needs to be mounted horizontally on a gutter
and attached with the wing nut screw (D) provided
ΠChoose a gutter location where the EVIE Sensor will not be
knocked by surrounding trees or by potentially strong wind
ΠEnsure the EVIE Sensor is with 50m range of your WX8
ΠUse the elbow screw (E) to level the EVIE Sensor on your gutter
CHECKING YOUR EVIE SENSOR
To check if your EVIE Sensor is
working, please follow these steps:
1. Fill the sensor with water
2. Stand at ground level, holding the
sensor under your gutter near the
intended installation point
3. You will need to wait up to a minute
for Holman Home to detect moisture
through the EVIE Sensor
4. Holman Home should currently
report (F) that the EVIE Sensor
is detecting and that automatic
watering starts have been disabled
5. Once Holman Home has confirmed it is
working correctly, empty the water and
install the sensor in the desired location
