York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP) BACnet points list

Updated 6 November 2026

Short answer

The 50-65 ton Series 100 rooftop's IPU control board speaks BACnet MS/TP on Port 1 and Modbus on Port 4. The table lists about 240 objects: air temperatures, pressures, airflows, CO2, unit mode and ten active fault and three warning codes as AIs; compressor, fan, heat and fault BIs; setpoints, limits and BAS inputs (zone, outdoor temperature and humidity) as AVs; and 0/1 BAS commands published as both AVs and BVs. Hot gas reheat points are included.

This page lists 243 BACnet objects for the York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP) — 98 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from York’s own free documentation, linked below.

BMS integration notes: York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP)

Integration in brief

Connect to Port 1 of the IPU control board on BACnet MS/TP. Command occupancy with OCCUPNCY_CMD, stop or release the unit with UNIT_STOP and write the occupied zone setpoints; feed zone temperature through AV 40 if the control method is set to comm zone temp. Read supply air and zone temperatures, supply fan status, unit mode and the fault inputs.

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
AV 88	OCCUPNCY_CMD	Occupancy command (1 = occupied)	Write
AV 93	UNIT_STOP	Unit stop (1 = stopped, 0 = normal)	Write
AV 21	OCC_ZN_COOL	Occupied zone cooling setpoint	Write
AV 22	OCC_ZN_HEAT	Occupied zone heating setpoint	Write
AI 58	UNIT_MODE	Current operating mode index	Read
BI 59	SUPPLY_FAN	Supply fan on/off	Read
AI 46	SUP_AIR_TEMP	Supply air temperature	Read
AI 60	ZONE_TEMP	Zone temperature	Read
BI 2	COL/HEAT_FLT	Cooling/heating fault (1 = faulted)	Read
AI 71	FAULT_1	Active fault code 1	Read

Enable & remote start

OCCUPNCY_CMD (AV 88 or BV 12) puts the unit in occupied (1) or unoccupied (0) mode and UNIT_STOP (AV 93 or BV 17) stops it (1) or returns it to normal operation (0). BAS reset and BAS sensor inputs must first be enabled at the unit with the SERVICE key; AV 40 zone temperature needs the control method set to comm zone temp.

Sensors & values from the BMS

AV 40 ZONE_TEMP_BAS feeds zone temperature when the control method is set to comm zone temp. AV 55 OAT_CURR_BAS, AV 56 OAH_CURR_BAS and AV 61 HUM_LVL_BAS feed outdoor temperature, outdoor humidity and zone humidity once enabled in the unit. AV 43 CO2_INSIDE and the BAS reset values (duct static, supply air) must be enabled with the SERVICE key before they are used.

Network setup

Port 1 carries BACnet MS/TP (P1 PROTOCOL = BACNET); baud 1200 to 76800 is set with the SERVICE key.
MAC address 0-127 from the IPU DIP switches or P1 MANUAL MAC ADDRESS; the device instance defaults to 23000 + MAC, or DE MODIFIER ADDRESS x 100 + DE MODIFIER OFFSET.
Cycle main power after changing the MAC address or port settings.
The Ethernet port is not functional; BACnet IP needs a gateway (the manual suggests a JCI NCE).
LON and N2 need an E-Link gateway on Port 1.

Watch out for

Each 0/1 command is listed as both an AV and a BV with the same name; use one of them, not both.
Points marked FlexSys, VAV, CV or 70-150 ton only report only on those units.
Setpoint and status AIs report in imperial units.

Integration notes

Access is from the READ/WRITE column. The table lists each 0/1 BAS command twice, as an AV (77-99) and a BV (1-23) with the same name; both are kept.
Descriptions are the user interface names from the table. Points marked FlexSys, VAV, CV or a tonnage range only exist on those units.
Units are taken from the description column where it states them (°F, "WC, CFM, %, ppm, psig).
The Modbus register addresses in the same table are not reproduced.
Compared with the 70-150 ton list this table adds FAULT_1-10 and WARNING_1-3 code AIs, hot gas reheat objects, and BAS outdoor temperature, outdoor humidity and zone humidity inputs; AV 15 is named RAT_HEAT_SP here.
FAULT and WARNING objects carry code numbers from the fault and warning tables in the IOM.

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 Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native 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.

Questions about the York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP)

How many BACnet points does the York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP) have?

This list has 243 BACnet objects: 79 analog inputs, 74 analog values, 66 binary inputs, 24 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP) BACnet points are writable?

98 of the 243 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 York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP) BACnet documentation?

The source is Series 100 Single Packaged Rooftop Units 50-65 Ton, Mod F - Installation, Operation, Maintenance (Table 53, BACnet MS/TP, Modbus, BACnet IP) (100.50-NOM5 (120)), revision 2020-01-20, published free by York at https://docs.johnsoncontrols.com/ductedsystems/api/khub/documents/PwDHFbfBgQxp4HQ4ucu1fw/content.

What are the minimum BACnet points to integrate the York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP)?

Start with AV 88 OCCUPNCY_CMD (Occupancy command (1 = occupied)); AV 93 UNIT_STOP (Unit stop (1 = stopped, 0 = normal)); AV 21 OCC_ZN_COOL (Occupied zone cooling setpoint); AV 22 OCC_ZN_HEAT (Occupied zone heating setpoint); AI 58 UNIT_MODE (Current operating mode index); BI 59 SUPPLY_FAN (Supply fan on/off); AI 46 SUP_AIR_TEMP (Supply air temperature); AI 60 ZONE_TEMP (Zone temperature); BI 2 COL/HEAT_FLT (Cooling/heating fault (1 = faulted)); AI 71 FAULT_1 (Active fault code 1).

How do I enable BMS control of the York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP)?

Can the BMS supply sensor values to the York Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP)?

How do I check these points on the real Series 100 YPAL Rooftop, 50-65 ton, Mod F (IPU, native BACnet MS/TP)?

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.
