Nilan CTS602 with HMI350T - BACnet (spaceLYnk gateway) BACnet points list
Updated 6 November 2026
Nilan's CTS602 controller speaks Modbus; on these commercial units a built-in Schneider spaceLYnk gateway serves a selected set of registers as a BACnet IP server. The BMS can switch the unit on and off, choose the operating mode and ventilation step, write the room temperature setpoint and cooling, supply-air limit, humidity and CO2 settings, reset alarms and edit the week program. It reads temperatures, pressures, humidity, CO2, fan speeds, relay outputs, digital inputs and the three most recent alarms.
This page lists 121 BACnet objects for the Nilan CTS602 with HMI350T - BACnet (spaceLYnk gateway) — 42 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Nilan’s own free documentation, linked below.

BMS integration notes: Nilan CTS602 with HMI350T - BACnet (spaceLYnk gateway)
Connect the spaceLYnk gateway to the BACnet IP network, set its IP address and a unique Device ID and enable its BACnet server. Run the unit with Control.RunSet (BV 2481), set Control.ModeSet, Control.VentSet and Control.TempSet, and read back the actual state, temperatures and the alarm status and codes.
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 2481 | Control.RunSet | Unit on/off (same as the ON/OFF keys) | Write |
| AV 2482 | Control.ModeSet | Mode: 0 off, 1 heat, 2 cool, 3 auto | Write |
| AV 2483 | Control.VentSet | Ventilation step: 0 off, 1-4 | Write |
| AV 2484 | Control.TempSet | Room temperature setpoint, °C | Write |
| AV 2465 | Alarm.Reset | 255 clears all alarms; 101-199 clears one code | Write |
| BV 2361 | Control.RunAct | Actual on/off state | Read |
| AV 2363 | Control.StateDisplay | Actual control state code | Read |
| AV 2335 | Input.T7_Inlet | Supply (inlet) air temperature after heater | Read |
| AV 2351 | Alarm.Status | Alarm bit mask: 0x80 = alarm(s) active | Read |
| AV 2352 | Alarm.List_1_ID | First active alarm display code | Read |
Enable & remote start
Control.RunSet (BV 2481) works like the panel ON/OFF keys; with it off, user input functions can still start the unit.
Network setup
- spaceLYnk default IP 192.168.0.10/24; web login on that address (credentials in the manual).
- BACnet server, Device ID, write priority, port (default 47808) and BBMD are set under Configurator > Utilities > System > Network > BACnet settings.
- IP settings are under Configurator > Utilities > System > Network > Interfaces; the gateway reboots after Apply Changes.
- Disable the KNX connection under Network > KNX connection.
Watch out for
- The spaceLYnk takes the Relinquish Default from the first read of each object; it cannot be changed later.
- Only a selected subset of the CTS602 Modbus list is published as BACnet objects.
- Once a weekly damper self-test day is set (AV 2490) it cannot be switched off.
- Some points apply only to Comfort, VPR or VPM models (see brackets).

Integration notes
- The object instance is the number in the '#' column (2305-2582); the manual gives the BACnet type as '2 (AV)' or '5 (BV)'.
- Square brackets list the unit families marked for a point when it does not apply to all of Comfort, VPR and VPM; T2_Inlet has no family marked.
- Alarm dates and times are 16-bit words packed in DOS date/time format.
- Control.ModeSet value 4 (Service) is read-only; the manual says to write Modbus register 1005 instead.
- Disable the spaceLYnk KNX connection and always answer No to its KNX error box, or several gateways can overwrite each other's setup.
- Source: Register layout, sections 4.1-4.13, pages 9-16 (121 objects).
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 CTS602 with HMI350T - BACnet (spaceLYnk gateway) 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 Nilan CTS602 with HMI350T - BACnet (spaceLYnk gateway)
How many BACnet points does the Nilan CTS602 with HMI350T - BACnet (spaceLYnk gateway) have?
This list has 121 BACnet objects: 88 analog values, 33 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Nilan CTS602 with HMI350T - BACnet (spaceLYnk gateway) BACnet points are writable?
42 of the 121 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 Nilan CTS602 with HMI350T - BACnet (spaceLYnk gateway) BACnet documentation?
The source is Nilan CTS602 w. HMI350T BACnet - BACnet Protocol, Version 2 (CTS602_w_HMI350T_BACnet Version 2), revision 2024-11-07, published free by Nilan at https://www.en.nilan.dk/Files/Files/Engelsk/Downloads/7.%20Modbus%20-%20BACnet/2024-11-07%20CTS602_w_HMI350T_BACnet_Version%202.pdf.
What are the minimum BACnet points to integrate the Nilan CTS602 with HMI350T - BACnet (spaceLYnk gateway)?
Start with BV 2481 Control.RunSet (Unit on/off (same as the ON/OFF keys)); AV 2482 Control.ModeSet (Mode: 0 off, 1 heat, 2 cool, 3 auto); AV 2483 Control.VentSet (Ventilation step: 0 off, 1-4); AV 2484 Control.TempSet (Room temperature setpoint, °C); AV 2465 Alarm.Reset (255 clears all alarms; 101-199 clears one code); BV 2361 Control.RunAct (Actual on/off state); AV 2363 Control.StateDisplay (Actual control state code); AV 2335 Input.T7_Inlet (Supply (inlet) air temperature after heater); AV 2351 Alarm.Status (Alarm bit mask: 0x80 = alarm(s) active); AV 2352 Alarm.List_1_ID (First active alarm display code).
How do I enable BMS control of the Nilan CTS602 with HMI350T - BACnet (spaceLYnk gateway)?
Control.RunSet (BV 2481) works like the panel ON/OFF keys; with it off, user input functions can still start the unit.
How do I check these points on the real CTS602 with HMI350T - BACnet (spaceLYnk gateway)?
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.
