Marley MarleyGard CD controller (BACnet) BACnet points list

Updated 4 November 2026

Short answer

The MarleyGard CD is a cooling-tower water treatment controller. It is a BACnet IP device that reports conductivity, pH, ORP, temperatures, water and flow meter totals, flow rates and 4-20 mA inputs for up to four systems, the setpoints and alarm limits, relay states and a large set of alarm flags. Every object in this list is read-only.

This page lists 453 BACnet objects for the Marley MarleyGard CD controller (BACnet) — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Marley’s own free documentation, linked below.

BMS integration notes: Marley MarleyGard CD controller (BACnet)

Integration in brief

Treat the MarleyGard CD as a monitoring device: read the chemistry inputs (conductivity, pH, ORP) and the flow switch for each system in use, and map the per-system All Alarms flags (BV 11, 80, 149, 218) as summary alarms.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Object	Name	Why	Access
AI 0	AI-000	System 1 conductivity	Read
AI 8	AI-008	System 1 pH	Read
AI 12	AI-012	System 1 ORP	Read
BI 0	BI-000	System 1 flow switch	Read
BV 11	BV-011	System 1: any active alarm	Read

Network setup

BACnet IP only (Annex J), on the same Ethernet port used for the WebAdvantage service.
Set the device instance in Configure > Network settings > BAC (some versions show DEV); 4194303 means unconfigured. The UDP port (47808) is set on the same screen.
The BMS must be on the same subnet as the controller, or routing must be set up for BACnet traffic.
Protocol revision 5, B-ASC; ReadProperty only (DS-RP-B).

Watch out for

All objects are read-only in this edition; setpoints and limits cannot be changed from the BMS.
ReadProperty only: no ReadPropertyMultiple or COV, so poll at a modest rate.
BV 93-133 are missing from the published list.

Integration notes

Object names are generic (BI-000, BV-011, AI-008 ...); what each object means is in the Purpose column, shown here as the description.
The setup screen shows an advantagecontrols.com server and the WebAdvantage service, and most object numbers and purposes match Advantage Controls' MegaTron BACnet H22 list, so it looks like a MarleyGard-branded MegaTron (the manual does not say so). This older edition lists fewer objects and marks every one read-only.
The published PDF repeats page 8 as page 9 and does not print BV 93-133; those objects are not listed here.
No engineering units or relay state texts are given; values follow the units configured in the controller.
Most points repeat for System #1 to #4 whether or not those systems are installed.

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the MarleyGard CD controller (BACnet) and exports what it actually has to Excel — free. New to BACnet?
