Advantage Controls MegaTron Controller (BACnet H21 / H25) BACnet points list

Updated 4 November 2026

Short answer

With the H21 or H25 option the MegaTron is a read-only BACnet IP device. It reports conductivity, pH, ORP, temperatures, water meter and flow meter values and up to sixteen 4-20 mA / 0-5 V inputs for up to four systems, plus alarm flags, setpoints, timer run times and relay states. Every object in this manual is marked Read Only, so the BMS can monitor but not adjust the controller.

This page lists 537 BACnet objects for the Advantage Controls MegaTron Controller (BACnet H21 / H25) — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Advantage Controls’s own free documentation, linked below.

BMS integration notes: Advantage Controls MegaTron Controller (BACnet H21 / H25)

Integration in brief

Monitoring only. Read the chemistry inputs (conductivity, pH, ORP) and the flow switch for each system in use, and the per-system alarm BVs you need (there is no summary alarm object in this list). All objects are read-only, so setpoints and relays are changed at the controller, not from the BMS.

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 ID lookup: Advantage Controls MegaTron Controller point IDs by name

Integration notes

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 MegaTron Controller (BACnet H21 / H25) and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the Advantage Controls MegaTron Controller (BACnet H21 / H25)

How many BACnet points does the Advantage Controls MegaTron Controller (BACnet H21 / H25) have?

This list has 537 BACnet objects: 72 analog inputs, 127 analog values, 4 binary inputs, 314 binary values, 20 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Advantage Controls MegaTron Controller (BACnet H21 / H25) BACnet points are writable?

None of the listed objects are marked writable in the source documentation.

Where is the official Advantage Controls MegaTron Controller (BACnet H21 / H25) BACnet documentation?

The source is MegaTron Controller Supplemental BACnet H21 / H25 Communications Manual (M-BACnet), revision 07/2026, published free by Advantage Controls at https://www.advantagecontrols.com/downloads/pdf/M-BACnet.pdf.

What are the minimum BACnet points to integrate the Advantage Controls MegaTron Controller (BACnet H21 / H25)?

Start with AI 0 AI-000 (System 1 conductivity); AI 8 AI-008 (System 1 pH); AI 12 AI-012 (System 1 ORP); BI 0 BI-000 (System 1 flow switch); AV 0 AV-000 (System 1 conductivity setpoint 1 (read only)).

How do I check these points on the real MegaTron Controller (BACnet H21 / H25)?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
