lES-RH Humidity Sens r
l1 ff 10 metre length f plugged
SELV cable
ES-RH Humidity Sens r
Designed to be compatible with the
Ecosmart system, this humidity sensor is
supplied with a pre-plugged, 10 metre length
of communications cable. Note: longer
lengths are available if required.
The sensor operates with Safe Extra Low
Voltage (SELV) with power supplied from
the fan unit via the communications cable.
The ES-RH Sensor will will vary the
ventilation rate automatically according to
the measured humidity.
The sensor has an adjustable 65-85% RH
set point.
Fault indicati n
The LED will change from green to red if
any fan connected in that zone has failed.
Multiple Sens rs
Multiple sensors can be connected to the
networ . Please refer to the actual fan
installation instructions for exact
quantities.
Installing the Sens r
The sensor unit should be installed away
from any direct source of heat (e.g.
radiators) and areas where it would be
subjected to waterspray.
The Sensor is supplied complete with
10 metres of connecting cable with plugs
attached. Sensors are also supplied with all
fixings and are clipped into a bac plate wall
mounting brac et.
a) Fix one end of the 10m cable to the fans
customer connection box (connection
soc ets mar ed NET).
b) Select a suitable location for the sensor
and arrange the cable in position. Leave
approx. 75mm of the cable free at the
mounting point to ease the connection
of the plug. (fig. 1).
c) Carefully separate the sensor from the
bac plate using a small screwdriver
(see Fig 2) Note: the sensor will remain
connected by its internal cable.
d) Release this cable from the brac et by
simply pulling the plug off the soc et pins
in the bac plate.
e) Before fixing the bac plate to the wall,
connect the wall fixed cable end plug to
the UPPER set of pins on the brac et
(fig 3) N te: check the c l ur c de
matching when fitting the plug onto the
pins.
Arrange the cable to lay in the cable slot
at the top of the bac plate moulding and
fix the brac et to the wall surface using
the screws supplied.
f) The sensor plug can now be connected
into the bac plate N te: check the c l ur
c de matching when fitting the plug onto
the pins.
Clip the sensor body in the bac plate arms
and adjust the sensor body to the desired
position.
Data cable installati n
A 4-core SELV data cable is used to
connect devices.
Do not run data cable in the same conduit
as the mains cables and ensure there is a
50mm separation between the data cable
and other cables. The maximum cable run
between any two devices is 300m when it
is installed in accordance with the
instructions.
Please note that the total data cable length
used in any system must be less than
1000m. Keep the number of cable joints to
a minimum to ensure the best data
transmission efficiency between devices.
Adjusting the sens r set p ints
Adjustable RH setting 65 - 85%
Assuming the sensor(s) are installed,
adjustment of the set points achieved by
tilting the sensor forwards which exposes
the adjustment aperture (see fig 5).
Using a small screwdriver, gently turn the
dial either cloc wise or anti-cloc wise to
increase or decrease the set point.
When adjustments are made to the sensor,
the LED light on the sensor front will flash
on and off to show the set point. First,
green flashes will indicate the set point in
TENS, then red flashes will indicate UNITS.
For example seven green flashes and five
red flashes show a set point of 75%.
