Marley Engineered Products Smart Series Plus digital heater controller (BACnet MS/TP) BACnet points list

Updated 12 November 2026

Short answer

The Smart Series Plus is a wall-mount digital controller for Marley Engineered Products heaters, built on Honeywell's BACnet FF (TB3026B) platform with application 5 loaded. It joins BACnet MS/TP and exposes the platform's setpoint, display, occupancy and schedule objects plus the heater application's settings: output enable, fan mode, standby, heating loop gains, fan start/stop and BMS scheduling options.

This page lists 208 BACnet objects for the Marley Engineered Products Smart Series Plus digital heater controller (BACnet MS/TP) — 179 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Marley Engineered Products’s own free documentation, linked below.

BMS integration notes: Marley Engineered Products Smart Series Plus digital heater controller (BACnet MS/TP)

Integration in brief

Set Output Enable (BV 2) ON, the MS/TP MAC and device instance (ISU 800-804), and decide between the internal schedule and BMS scheduling (BV 56). Then write occupancy (BV 40) and the occupied setpoint AV 90, and read the room temperature, active heating setpoint and occupied status.

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 2	Output Enable	Output enable; must be ON for the heater to run	Write
BV 56	Enable BMS Scheduling	Enable BMS scheduling (overrides internal schedule)	Write
AV 90	Setpoint (SP)	Occupied space setpoint	Write
AV 96	Unoccupied Heating SP	Unoccupied heating setpoint	Write
BV 9	Enable Communication Failure	Go occupied on MS/TP comm failure	Write
AV 104	Sensed Room Temperature	Room temperature (built-in sensor)	Read
AV 100	Current Heating SP	Active heating setpoint	Read
BV 67	Occupied/Unoccupied Status	Occupied / unoccupied status	Read

Enable & remote start

BV 2 Output Enable must be ON. With BV 56 active the BMS schedules occupancy (BV 40, priority array) instead of the internal schedule.

Heartbeat & communication loss

BV 9 Enable Communication Failure: when active the controller falls back to occupied if MS/TP communication fails.

Network setup

Factory defaults: MS/TP MAC 0 (valid 0-127), device instance 0009999 (valid 0-4194302).
MS/TP MAC is ISU 800 (0-127); device instance is entered in parts through ISU 801-804.
Application selection AV 49 must stay at 5 for Marley heaters.

Watch out for

Table 24 marks several display objects 'Do Not Change'; leave them at their defaults.
SYSTEM block OFF (BV 102 visible) overrides scheduled occupied to unoccupied.

Marley Engineered Products Smart Series Plus digital heater controller (BACnet MS/TP) BACnet objects

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.

Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes

The appendix gives each object a label in an 'Object Name' column, but its property tables say the Object_Name property reads 'AV-nnn' / 'BV-nnn' / 'MV-nnn' for most objects. The labels are used as names here; a scan may show the AV-nnn form.
Physical I/O objects (AI 0-2, AO 0-7, BI 0-2, BO 0-5) and the general-use AV 0-89 / BV 0-63 depend on the loaded application (DDC file); they are not listed here except where the guide names them.
BV 40 (general-use range) is the occupancy command and supports a priority array.
Access comes from the appendix where it has an access column; otherwise it is inferred (displayed/sensed/current/status points and multistates read-only, others writable).
The ordered list in this guide marks the humidity, UV-lamp and several display objects RESERVED; they are left out. Application points (AV 17-79, BV 2-56) come from the guide's setup tables (Tables 21, 23 and 24), with defaults in the descriptions.
Output Enable (BV 2) must be set ON at start-up or the relays stay off.
The object set is the Honeywell BACnet FF platform; see the Honeywell TB3026B list for the full platform including humidity objects.

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 Smart Series Plus digital heater controller (BACnet MS/TP) 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.
