Programming the VT8600 with Lua
The VT8600 Room Controllers are programmable using
the open programming language Lua. Although BMS
often use open protocols and standards, their Program
BACnet objects and scripting features remain proprietary
and incompatible with third party devices. The VT8600
Room Controllers use of an open language enables
interopreability with all systems.
Programming with BMS Integration
When integrated into a BACnet MS/TP BMS, the VT8600
offers 10 Program BACnet objects able to contain 480
characters each. No special software, license or tool is
required.
• BACnet MS/TP integration into BMS
• 10 Program BACnet objects (Lua scripts)
• Each object can contain 480 characters max
Programming without Integration
When there is no BACnet MS/TP integration, a Lua script can
be uploaded directly into the VT8600 unit using the Uploader
VT8000 tool. Unlike the 10 PG objects used when the unit is
integrated via BACnet MS/TP, there is only one script, which
can contain up to 16KB.
• No BACnet MS/TP integration
• 1 Lua script of 16KB max
• Uploader VT8000 tool allows upload of scripts
Applications for HVAC and Beyond
Programming can be used to go beyond the pre-congured
control sequences of the VT8600 to create customized HVAC
applications. It can also be used to comply with specic
project requirements and manage other applications, such as
lighting and other equipment.
Using Lua scripts also enables you to take advantage of the
extra inputs and outputs of the VT8600 to manage other
devices, such as sensors and relays.
Uploader VT8000
Lua scripts, standby screen images and rmware upgrades
can be loaded into the VT8600 using the Uploader VT8000
tool and a USB/Micro-USB cable.
