Bosch Control Air 5600 - Water to Air (WAZ software) BACnet points list
Updated 28 October 2026
The Control Air 5600 is Bosch's factory-mounted DDC controller for water-source heat pumps. It speaks BACnet MS/TP (or BACnet over ARC156, Modbus, N2 and Lon) and exposes occupancy, mode, setpoint, sensor, configuration and alarm points as AV/BV/MSV objects. The same point list also documents Modbus registers and N2/LON equivalents.
This page lists 174 BACnet objects for the Bosch Control Air 5600 - Water to Air (WAZ software) — 73 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Bosch’s own free documentation, linked below.

BMS integration notes: Bosch Control Air 5600 - Water to Air (WAZ software)
Leave Control Source at its default (BAS Occupancy Command), then command occupied/unoccupied with occupancy_cmd_1 and set the occupied cooling/heating setpoints. Choose the zone temperature source (ZS sensor, remote sensor or BAS value) and, if the BMS supplies the temperature, write bas_sen_val_1. Monitor current_alarm_1, alm_status_1 and the effective zone temperature.
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 1 | occupancy_cmd_1 | BAS occupied command; 1 enables unit operation | Write |
| AV 15 | ctrl_source_1 | Occupancy source; 2 = BAS occupancy command (default) | Write |
| MV 3 | zone_mode_1 | Auto / heat / cool / off | Write |
| AV 4 | occ_clg_stpt_1 | Occupied cooling setpoint | Write |
| AV 2 | occ_htg_stpt_1 | Occupied heating setpoint | Write |
| AV 16 | sys_status_1 | Unoccupied / occupied / fan only / heating / cooling state | Read |
| AV 7 | eff_zone_temp_1 | Zone temperature in use | Read |
| AV 17 | current_alarm_1 | Active alarm code | Read |
| BV 24 | alm_status_1 | Alarm present flag | Read |
Enable & remote start
Set ctrl_source_1 (AV 15) to 2 = BAS Occupancy Command (factory default) and write occupancy_cmd_1 (BV 1) = 1 to occupy the unit. Other sources are a digital input enable, keypad schedule or manual on. The BAS loop enable point (loop_enabled_1, BV 23) must be 1 to allow heating/cooling; it defaults to 1.
Heartbeat & communication loss
No communication timeout is described. If the BAS temperature source is used and nothing is ever written, the zone temperature defaults to 74 °F; after that the last written value is used indefinitely.
Sensors & values from the BMS
Set the compressor control mode (comp_mode_1, AV 64) to 2 = Zone Control - BAS Sensor and write the zone temperature to bas_sen_val_1 (AV 19). BAS humidity goes to bas_rh_sen_val_1 (AV 56) with rh_bas_sel_1 (AV 51); BAS CO2 to bas_co2_val_1 (AV 49) with co2_bas_ena_1 (AV 106); mixed air to bas_mat_1 (AV 86); outdoor air to effective_oat_1 (AV 29).
Network setup
- BACnet MS/TP runs on the EIA-485 port; the BAS Port Settings DIP switches select the protocol (BACnet MS/TP, N2, Modbus) and baud rate (9.6 to 76.8 kbps), the same for every controller on the trunk.
- The two rotary dials set the MAC address (tens and ones); the controller only reads them at power-up, so change them with power off.
- A Communication jumper selects EIA-485 (MS/TP, N2, Modbus, Lon) or BACnet over ARC156 at 156 kbps.
- Setpoints and configuration can also be changed locally with a BACview terminal or Virtual BACview.
Watch out for
- With a ZS or remote sensor selected, the controller looks for it during the first 30 s after power-up; if missing, the unit stays unoccupied, alarms and shows -60 °F.
- Writing bas_smoke_1 = 1 shuts the supply fan, compressors and reheat valve off.
- The input/output configuration AVs (in1/in2/ao/bo cfg) change how hardware I/O is used; treat them as commissioning settings, not operating points.
- There is a 1-minute delay when the unit changes between heating and cooling.

Integration notes
- Object names end in _1 as printed in the points list.
- Two names were split across lines in the PDF and were re-joined here: eq_temp_1 (AV 1902) and zs_sen_combo_sel_1 (AV 40).
- Many AV points are configuration selectors (input/output assignments); several only matter when that option (economizer, hot gas reheat, VFD, CO2, damper) is installed.
- Writable points are those not marked read-only in the list.
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. Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Control Air 5600 - Water to Air (WAZ software) and exports what it actually has to Excel — free.

Questions about the Bosch Control Air 5600 - Water to Air (WAZ software)
How many BACnet points does the Bosch Control Air 5600 - Water to Air (WAZ software) have?
This list has 174 BACnet objects: 88 analog values, 82 binary values, 4 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Bosch Control Air 5600 - Water to Air (WAZ software) BACnet points are writable?
73 of the 174 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 Bosch Control Air 5600 - Water to Air (WAZ software) BACnet documentation?
The source is Bosch TT - Water to Air Network Integration Points List (WAZ.1.03), published free by Bosch at https://www.bosch-homecomfort.com/us/media/country_pool/service/technical_guides/ipl_waz_1_03.pdf.
What are the minimum BACnet points to integrate the Bosch Control Air 5600 - Water to Air (WAZ software)?
Start with BV 1 occupancy_cmd_1 (BAS occupied command; 1 enables unit operation); AV 15 ctrl_source_1 (Occupancy source; 2 = BAS occupancy command (default)); MV 3 zone_mode_1 (Auto / heat / cool / off); AV 4 occ_clg_stpt_1 (Occupied cooling setpoint); AV 2 occ_htg_stpt_1 (Occupied heating setpoint); AV 16 sys_status_1 (Unoccupied / occupied / fan only / heating / cooling state); AV 7 eff_zone_temp_1 (Zone temperature in use); AV 17 current_alarm_1 (Active alarm code); BV 24 alm_status_1 (Alarm present flag).
How do I enable BMS control of the Bosch Control Air 5600 - Water to Air (WAZ software)?
Set ctrl_source_1 (AV 15) to 2 = BAS Occupancy Command (factory default) and write occupancy_cmd_1 (BV 1) = 1 to occupy the unit. Other sources are a digital input enable, keypad schedule or manual on. The BAS loop enable point (loop_enabled_1, BV 23) must be 1 to allow heating/cooling; it defaults to 1.
Does the Bosch Control Air 5600 - Water to Air (WAZ software) need a BACnet heartbeat or have a communication timeout?
No communication timeout is described. If the BAS temperature source is used and nothing is ever written, the zone temperature defaults to 74 °F; after that the last written value is used indefinitely.
Can the BMS supply sensor values to the Bosch Control Air 5600 - Water to Air (WAZ software)?
Set the compressor control mode (comp_mode_1, AV 64) to 2 = Zone Control - BAS Sensor and write the zone temperature to bas_sen_val_1 (AV 19). BAS humidity goes to bas_rh_sen_val_1 (AV 56) with rh_bas_sel_1 (AV 51); BAS CO2 to bas_co2_val_1 (AV 49) with co2_bas_ena_1 (AV 106); mixed air to bas_mat_1 (AV 86); outdoor air to effective_oat_1 (AV 29).
How do I check these points on the real Control Air 5600 - Water to Air (WAZ software)?
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.
