Johnson Controls VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat) BACnet points list

Updated 4 November 2026

Short answer

Application 1717-4 (Incr HW Reheat) is one of the ten preloaded applications in the Johnson Controls VAV1717 controller, which has a built-in damper actuator and velocity pressure sensor and runs on BACnet MS/TP. It controls a single-duct VAV box with an incremental (floating) 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 and the loop and state diagnostics.

This page lists 91 BACnet objects for the Johnson Controls VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat) — 40 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Johnson Controls’s own free documentation, linked below.

BMS integration notes: Johnson Controls VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat)

Integration in brief

Set the MS/TP address on the DIP switches, load the 1717-4 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 command.

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.

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 VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat) and exports what it actually has to Excel — free.

Questions about the Johnson Controls VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat)

How many BACnet points does the Johnson Controls VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat) have?

This list has 91 BACnet objects: 6 analog inputs, 2 analog outputs, 59 analog values, 1 binary input, 5 binary values, 18 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Johnson Controls VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat) BACnet points are writable?

40 of the 91 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 VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat) 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 VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat)?

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 278004 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, %).

How do I enable BMS control of the Johnson Controls VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat)?

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 VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat)?

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 VAV1717 VAV Controller - Application 1717-4 (Incr HW Reheat)?

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.
