Johnson Controls VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan) BACnet points list

Updated 4 November 2026

Short answer

Application 1732-8 (Incr HW Reheat Var Speed Series Fan) is one of the ten preloaded applications in the Johnson Controls VAV1732 controller, which has a built-in damper actuator and velocity pressure sensor and runs on BACnet MS/TP. It controls a series fan-powered VAV box with a variable-speed fan and an incremental hot water reheat valve. Points cover occupancy and unit enable, temperature and airflow setpoints, zone sensors, airflow in L/s, CFM and CMH, damper output, the reheat valve output, the fan command and the loop and state diagnostics.

BMS integration notes: Johnson Controls VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan)

Integration in brief

Set the MS/TP address on the DIP switches, load the 1732-8 application, then enable the unit with UNITEN-MODE, drive occupancy through OCC-SCHEDULE and write the occupied setpoints. Read zone temperature, effective occupancy, airflow and damper output plus the heat and fan commands.

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.

Enable & remote start

UNITEN-MODE (Shutdown or Enable, default Enable) turns the box on or off. Occupancy comes from OCC-SCHEDULE (Occupied, Unoccupied, Standby or Not Set) written by the supervisory schedule; OCC-OVERRIDE overrides it, and EFF-OCC shows the result. SYSTEM-MODE (default Auto) can force cool only, heat only, fan only, water flush or purge.

Sensors & values from the BMS

SA-T (writable, default 13 °C) is the supply air temperature used for automatic warmup: warmup starts when SA-T and ZN-T are reliable and SA-T exceeds ZN-T plus WCT-DIFF; otherwise the BAS can command warmup with WC-C. With ZONE SETPOINT SOURCE set to Remote, the box uses BAS ZN-SP instead of the sensor setpoint.

Questions about the Johnson Controls VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan)

How many BACnet points does the Johnson Controls VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan) have?

This list has 97 BACnet objects: 6 analog inputs, 3 analog outputs, 61 analog values, 1 binary input, 1 binary output, 5 binary values, 20 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Johnson Controls VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan) BACnet points are writable?

41 of the 97 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 Johnson Controls VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan) BACnet documentation?

The source is VAV1717 and VAV1732 VAV Controllers Application Note (LIT-12013794), revision 2021-08-09, published free by Johnson Controls at https://docs.johnsoncontrols.com/bas/api/khub/documents/1A9bXr239BVM1oXYaNZBSA/content.

What are the minimum BACnet points to integrate the Johnson Controls VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan)?

Start with MV 77 UNITEN-MODE (Unit enable: Shutdown or Enable); MV 59 OCC-SCHEDULE (Occupancy from the BAS schedule); AV 3474 CLGOCC-SP (Occupied cooling setpoint, °C); AV 3475 HTGOCC-SP (Occupied heating setpoint, °C); MV 3290 EFF-OCC (Occupancy in effect); AV 277998 ZN-T (Zone temperature, °C); AV 3515 SA-F (Supply airflow, L/s); AO 2131 DPR-O (Damper output, %); AO 2015 HTG-O (Heating valve output, %); BO 2045 SF-C (Box fan on/off output).

How do I enable BMS control of the Johnson Controls VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan)?

UNITEN-MODE (Shutdown or Enable, default Enable) turns the box on or off. Occupancy comes from OCC-SCHEDULE (Occupied, Unoccupied, Standby or Not Set) written by the supervisory schedule; OCC-OVERRIDE overrides it, and EFF-OCC shows the result. SYSTEM-MODE (default Auto) can force cool only, heat only, fan only, water flush or purge.

Can the BMS supply sensor values to the Johnson Controls VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan)?

SA-T (writable, default 13 °C) is the supply air temperature used for automatic warmup: warmup starts when SA-T and ZN-T are reliable and SA-T exceeds ZN-T plus WCT-DIFF; otherwise the BAS can command warmup with WC-C. With ZONE SETPOINT SOURCE set to Remote, the box uses BAS ZN-SP instead of the sensor setpoint.

How do I check these points on the real VAV1732 VAV Controller - Application 1732-8 (Incr HW Reheat Var Speed Series Fan)?

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.
