WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet BACnet points list

Updated 6 November 2026

Short answer

BACnet point list for a WaterFurnace heat pump running the IntelliZone2 zoning system. Besides the usual Aurora heat pump points (ABC inputs and outputs, ECM blower, VS pump, refrigerant and power data, humidity and DCV settings) it has a repeated block per zone 1-6 with zone temperature, BAS override, occupancy, setpoints, demand and damper limits. A large share of the rows are marked 'do not map to BAS'.

This page lists 546 BACnet objects for the WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet — 403 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from WaterFurnace’s own free documentation, linked below.

BMS integration notes: WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet

Integration in brief

Map the system points (emergency shutdown, alarm reset, mode, alarm value) once and then one zone block per active zone. Each zone takes a BAS occupancy signal and occupied heating/cooling setpoints, and reports its occupancy status and usable temperature. A zone temperature from the BAS needs BV 11x0 set to BAS and the value on AV 11x2.

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

BV 101 em_shutdown_c shuts the unit down and BV 105 load_shed_c sheds load from the network. Occupancy can come from the BAS per zone (BV 11x6, MV 11x0 or AV 11x9, depending on BV 1000) or from the internal schedule; BV 502 picks internal or external schedule.

Sensors & values from the BMS

For a BAS zone temperature, set BV 11x0 (temp_selector) to BAS and write AV 11x2 (zone_temp_ovrd). AV 504, AV 506 and AV 508 accept BAS space humidity, CO2 and VOC values, and AV 606 a BAS outdoor air temperature (BV 1017 picks the OAT source).

Object ID lookup: WaterFurnace IntelliZone2 IZ2 point IDs by name

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 IntelliZone2 (IZ2) Zoning System, Aurora BACnet 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 WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet

How many BACnet points does the WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet have?

This list has 546 BACnet objects: 354 analog values, 152 binary values, 40 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet BACnet points are writable?

403 of the 546 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 WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet BACnet documentation?

The source is IZ2 BACnet Point List, revision 2021-06-16, published free by WaterFurnace at https://www.waterfurnace.com/literature/intellizone/IZ2%20BACnet%20Point%20List.xlsx.

What are the minimum BACnet points to integrate the WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet?

Start with BV 101 em_shutdown_c (Emergency shutdown command); BV 1106 occ_man_cmd_bv_z1_c (Zone 1 occupancy from the BAS); AV 1111 occ_clg_setpt_z1_c (Zone 1 occupied cooling setpoint); AV 1112 occ_htg_setpt_z1_c (Zone 1 occupied heating setpoint); BV 130 alarm_reset_c (Alarm reset); MV 100 mode_msv (Unit operating mode); AV 1110 eff_occ_st_z1 (Zone 1 effective occupancy status); AV 1100 zone_temp_z1 (Zone 1 temperature in use); BV 141 alarm_hdw_stat_a (ABC alarm output status); AV 119 alarm_enum (Combined system alarm code).

How do I enable BMS control of the WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet?

BV 101 em_shutdown_c shuts the unit down and BV 105 load_shed_c sheds load from the network. Occupancy can come from the BAS per zone (BV 11x6, MV 11x0 or AV 11x9, depending on BV 1000) or from the internal schedule; BV 502 picks internal or external schedule.

Can the BMS supply sensor values to the WaterFurnace IntelliZone2 (IZ2) Zoning System, Aurora BACnet?

For a BAS zone temperature, set BV 11x0 (temp_selector) to BAS and write AV 11x2 (zone_temp_ovrd). AV 504, AV 506 and AV 508 accept BAS space humidity, CO2 and VOC values, and AV 606 a BAS outdoor air temperature (BV 1017 picks the OAT source).

How do I check these points on the real IntelliZone2 (IZ2) Zoning System, Aurora BACnet?

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.
