Installation Manual
10.0 COMMISSIONING
Before commissioning the unit, ensure that all equipment has been
assembled in accordance with the installation procedure all instances
where the unit is in operation the access doors should remain closed; at
no time, during maintenance or otherwise, should anyone be inside a
unit whilst it is in operation.
10.1 Basic Commissioning
The Ecosmart Connect system can only be commissioned by modifying
the controller BACnet object values (in software).
This can be done by connecting to the controller across the network
using any BACnet compatible software.
If a BACnet compatible network is not available, an ESCO-LCD is
required to commission the system. The ESCO-LCD can be permanently
connected on the FC bus (with a separate power supply), or a special
RJ11 connection cable (ESCO-LCD-3M) is supplied for temporary
connection directly to the controller (self-powered). All values will be
retained by the controller once the LCD is disconnected.
See ESCO-LCD section for more connection information, see sections
8.15 & 12.1 for BACnet object lists.
