Ecosmart Speed Control
Installation and Maintenance
Always handle with care to avoid damage and distortion, and where
lifting slings are employed use spreaders to ensure slings do not come
into contact with the unit case, or control pack (see fig. 2).
2.2 Dimensions (mm) & Weights (Kg)
Control sizes are selected by matching the unit full load current with
the control code i.e. control code ES-ISC3.3A is suitable for a fan with a
maximum full load current of 3.3A.
The Inverter overload is pre-set at the rating plate value, if a lower
setting is required fit an appropriately sized overload relay to the output
contactor and adjust accordingly.
1.0 INTRODUCTION
ES-ISC Ecosmart Controls
The Ecosmart Energy Saving Speed
Control is designed to control selected
Nuaire fans and to match the range of
integrated Ecosmart control systems.
The control is only available for

accordance with the appropriate authority and conforming to all
statutory and governing regulations i.e. IEE, CIBSE, HVCA etc.
The Ecosmart control is desgined to be installed indoors, away from
any water spray or steam generating source. Fix or mount in upright
position to a secure vibration free vertical surface (see fig. 1 & 3). Ensure
the ventilation grilles are free of obstruction.
If the unit is installed outdoors, the matching size weathering cover
ES-ISC-WP* must be used to provide weather protection.
