Selection Guide
Use the following criteria to confirm the ABB 6138/11-83-500 is the right choice — or to identify the best alternative:
- Step 1 — Protocol: Confirm your system uses KNX/EIB TP. If using Modbus RTU or BACnet MS/TP natively, a gateway or different controller family is required.
- Step 2 — Setpoint Range: Verify the required temperature setpoint range matches the controller’s configured limits (typically 5–35 °C).
- Step 3 — Sensor Inputs: Determine if additional inputs (humidity, CO₂, presence) are needed — if so, consider the 6127 series.
- Step 4 — Display & UI: Confirm whether end-users require a display or push-button interface; select the appropriate 6138 sub-variant.
- Step 5 — Quantity & Lead Time: For large projects, contact Konmask.com for volume pricing and availability confirmation.

Replacement & Compatibility FAQ
Q: Can I replace the 6138/11-83-500 with a Siemens QAX34.1 directly?
A: Functionally similar, but KNX group object mapping differs. Re-parameterization in ETS is required. Recommended only for experienced KNX integrators.
Q: Is the 6138-0-0005 the same as 6138/11-83-500?
A: Yes — these are alternate part number formats for the same ABB product. Both refer to the same SKU.
Q: Do you supply the ETS application file with the unit?
A: We can provide the download link to the official ABB ETS application. Contact us after purchase.
Q: What is the minimum order quantity?
A: No minimum order quantity. Single units and bulk orders are both welcome.
Q: Can this controller work without a KNX bus?
A: No — the 6138/11-83-500 is a bus-powered KNX device and requires a KNX TP infrastructure to operate.
