Field Devices
Field devices (such as the MS4-TH thermostat, pictured below) provide the information and control points for each equipment controller. These devices are physically connected to their associated equipment controllers, and are installed by Synergy technicians on site. The MS4-TH is a touchscreen combination temperature/humidity sensor, most often used to measure spaces served by VAVs, single zone air handling units, and fan coil units. More information on field devices and our vendors can be found at the bottom of the page.
Equipment Controller
Alerton VLC: Virtual Logic Controllers (VLCs), such as the Alerton VLC-853, are used to control and monitor HVAC equipment. These controllers are all located on site, typically as near to the controlled equipment as possible, and communicate to each other and the main building controller through an MSTP connection.
Main Building Controller
Alerton ACM: The Ascent Control Module, or ACM, can support multiple MSTP network trunks and can be set up to connect directly to a networked user workstation or to be accessible through a password protected IP connection. All equipment controllers will communicate on MSTP networks that are connected to the ACM. A different type of main building controller can be found in the Honeywell section below.
Workstation
The workstation can be one computer connected to the ACM or, if the customer requires, it can be any computer capable of connecting to a designated IP address for the building automation system. The workstation will view and modify equipment status through a program called Alerton Ascent Compass. This is a web-based user interface that is built individually for each unique job/system which allows the end user to view and modify all equipment monitoring and control points.
