IMPORTANT! Please refer to the
installation instructions of the fan to
check the compatibility of this unit.
Parts check list:
●1 Ecosmart sensor or enabler
●1 off 10 metre length of pre-plugged
SELV cable
All units are compatible with the Nuaire
Ecosmart system, and operates with
Safe Extra Low Voltage (SELV) with
power supplied from the fan via the
communications cable.
Installed Environment
0 - 400C up to 90%RH non-condensing.
Installing the unit
The unit must be installed away from any
direct source of heat (e.g. radiators) and
areas where it would be subjected to steam
or water spray.
The mounting surface must be vibration
free.
The unit is supplied complete with 10 metres
of connecting cable with plugs attached.
Fasteners for wall fixing are included in the
package.
a) Fix one end of the 10m cable to the fans
customer connection box (connection
sockets marked 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) Hold the base of the unit with one hand
and the top half with the other. Twist the
upper half anti-clockwise to open the unit.
(Fig. 2).
d) Feed the cable through the hole of the
lower half of the unit and mark the
locations of the fixing holes on the wall.
There is a raised line inside the base
of the unit to aid alignment to the
horizontal or vertical. (see Fig.3).
e) Fix the base of the unit to the wall
using the fasteners provided, or other
suitable fasteners.
f) Plug the cable into the socket of the
PCB. (Fig.4).
g) Align the slots of the upper and lower
halves of the unit and twist the upper half
clockwise to lock the 2 halves together.
(see Fig. 5).
Data cable installation
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 set point
Use a small screwdriver through the hole
of the casing to reach the adjustment
potentiometer. Gently turn the screwdriver
either clockwise or anti-clockwise to
increase or decrease the set point.
Alternatively, open the unit to gain easy
access to the pot.
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 two green flashes and three
red flashes show a set point of 23.
