NuAire ECOSMART CLASSIC CONTROL Series Commissioning Manual

Introduction
This leaflet is intended to support the main Installation and
Maintenance Instructions supplied with the fan unit, available
on request from the Nuaire Technical Library. Telephone:

1. Getting started
The Ecosmart Twinfan is designed for maximum control
flexibility. Apart from the power supply, an enabling signal is
always required to set the fan running. This enabling signal
can be a switched live signal (connected to the SL terminal of
each fan) or an enabling device plugged in the NET connection
(see table 'Ecosmart compatible devices').
If an enabling signal is not available, connect a link wire
between 'L' & 'SL'
Additional sensor and manual control may be added. For
example: to run the fan with a temperature sensor, connect a
link across L to SL (enabling signal) and connect a temperature
sensor in one of the sockets labelled 'NET' The fan will now
adjust it's speed according to temperature.
To obtain manual control, connect a link across L to SL
(enabling signal) and connect a user control in one of the
sockets labelled 'NET'.
Figure 1. Example Fan Control module connection details.
Note:
Remove the link wire if a switched live
signal is present or an enabling device
or a BMS is connected to the'NET
