Tigerflow Mark VI pump system controller BACnet points list
Updated 12 November 2026
The Mark VI controls up to three VFD pumps on zone differential pressure. Over BACnet it reports pump run commands, VFD run and fault feedback, HOA positions, zone differential pressures, flow, pump speeds and supply/return temperatures. The BMS can write a system disable (BV 41) and a differential pressure setpoint for zones 1-3 (AV 41-43).
This page lists 49 BACnet objects for the Tigerflow Mark VI pump system controller — 4 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Tigerflow’s own free documentation, linked below.

BMS integration notes: Tigerflow Mark VI pump system controller
Write BV 41 to disable or release the system and the zone differential pressure setpoints AV 41-43 if the BMS owns the setpoint. Read zone pressures, flow, pump run and fault flags and the general alarm.
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 |
|---|---|---|---|
| BV 41 | Remote System Disable - BAS Signal | System disable from the BMS | Write |
| AV 41 | Remote BAS Zone 1 Setpoint | Zone 1 differential pressure setpoint, psi | Write |
| AV 60 | Zone 1 Differential Pressure | Zone 1 differential pressure, psi | Read |
| AV 64 | Flow Rate | System flow, gpm | Read |
| BV 21 | Pump 1 Run Command | Pump 1 called to run (repeat for pumps 2-3) | Read |
| AV 65 | Pump 1 Speed Signal (%) | Pump 1 speed signal, % (repeat for pumps 2-3) | Read |
| BV 71 | Pump 1 Fault | Pump 1 fault (repeat for pumps 2-3) | Read |
| BV 86 | General/Fatal Alarm | Any general or fatal alarm | Read |
Enable & remote start
BV 41 Remote System Disable - BAS Signal is the only writable binary; the list gives 1 = ON but does not say how it combines with the hard-wired disable input.
Sensors & values from the BMS
AV 41-43 accept zone differential pressure setpoints from the BAS; the list does not say how the controller chooses between local and BAS setpoints.
Watch out for
- The list does not describe BAS-setpoint selection or comm-loss behaviour; confirm on site before relying on AV 41-43.

Integration notes
- Instance plan differs from the Mark V list; do not reuse a Mark V map.
- Instances are printed as BV0001.. / AV0001.. with gaps that are not in the list.
- The list has four zone pressure sensor failure flags but only three zone pressure readings and three BAS zone setpoints.
- The point list does not state the BACnet transport (IP or MS/TP) or device addressing.
- Units as printed: pressure psi, flow GPM, temperatures °F.
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 Mark VI pump system controller and exports what it actually has to Excel — free. New to BACnet?

Questions about the Tigerflow Mark VI pump system controller
How many BACnet points does the Tigerflow Mark VI pump system controller have?
This list has 49 BACnet objects: 12 analog values, 37 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Tigerflow Mark VI pump system controller BACnet points are writable?
4 of the 49 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.
Where is the official Tigerflow Mark VI pump system controller BACnet documentation?
The source is MARK VI - BACNet POINT LIST, revision 2018-04-19, published free by Tigerflow at https://tigerflow.com/demo/wp-content/uploads/2018/05/Mark-VI-BACNet-Point-List-20180419-1.pdf.
What are the minimum BACnet points to integrate the Tigerflow Mark VI pump system controller?
Start with BV 41 Remote System Disable - BAS Signal (System disable from the BMS); AV 41 Remote BAS Zone 1 Setpoint (Zone 1 differential pressure setpoint, psi); AV 60 Zone 1 Differential Pressure (Zone 1 differential pressure, psi); AV 64 Flow Rate (System flow, gpm); BV 21 Pump 1 Run Command (Pump 1 called to run (repeat for pumps 2-3)); AV 65 Pump 1 Speed Signal (%) (Pump 1 speed signal, % (repeat for pumps 2-3)); BV 71 Pump 1 Fault (Pump 1 fault (repeat for pumps 2-3)); BV 86 General/Fatal Alarm (Any general or fatal alarm).
How do I enable BMS control of the Tigerflow Mark VI pump system controller?
BV 41 Remote System Disable - BAS Signal is the only writable binary; the list gives 1 = ON but does not say how it combines with the hard-wired disable input.
Can the BMS supply sensor values to the Tigerflow Mark VI pump system controller?
AV 41-43 accept zone differential pressure setpoints from the BAS; the list does not say how the controller chooses between local and BAS setpoints.
How do I check these points on the real Mark VI pump system controller?
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.
