A practical, legal overview for owners, installers, and service technicians 1. What is the Danfoss MCT‑10? | Feature | Description | |---------|-------------| | Product line | Danfoss MCT (Modular Control & Test) is a family of digital controllers used in heating, ventilation, air‑conditioning, and refrigeration (HVAC‑R) systems. | | MCT‑10 model | A compact, 10‑channel controller that can host a variety of I/O modules (temperature, pressure, flow, etc.). It runs the MCT‑Software (configuration, monitoring, and diagnostics). | | Typical applications | Chiller plant control, heat‑pump monitoring, building‑automation zones, and test‑equipment rigs. | | Why a license key? | The software that programs the controller contains proprietary algorithms, advanced diagnostics, and cloud‑connectivity features. Danfoss protects this intellectual property with a license‑key system that activates the full feature set for a specific hardware unit. | 2. What Is a License Key, and How Does It Work? | Aspect | Explanation | |--------|-------------| | Definition | A string of characters (often alphanumeric) that uniquely authorises a particular MCT‑10 controller to run the full‑feature version of the Danfoss software. | | Binding | The key is typically bound to the controller’s serial number or hardware ID, so it cannot be reused on a different unit. | | Activation flow | 1. Install the MCT‑Software on a PC. 2. Connect the PC to the MCT‑10 via USB, Ethernet, or the Danfoss‑specific interface. 3. The software reads the controller’s ID and prompts you for a license key. 4. You enter the key; the software validates it against Danfoss’s licensing server (or offline checksum file). 5. Once validated, the controller is unlocked for the licensed features. | | Types of licenses | • Per‑device (single‑unit) – one key per controller. • Floating/Network – a central server holds a pool of seats that can be checked out by multiple controllers (rare for MCT‑10). • Time‑based trial – a temporary key for evaluation (usually 30‑days). | 3. How to Obtain a Legitimate License Key | Step | Action | Details | |------|--------|---------| | 1. Verify product eligibility | Confirm you have a genuine Danfoss MCT‑10 (serial number on the label). | Counterfeit hardware will not accept a valid key. | | 2. Register the device | Log in to the Danfoss Customer Portal (https://portal.danfoss.com) and create an account if you do not have one. | Registration links the serial number to your account and simplifies future renewals. | | 3. Purchase the appropriate software package | Options include: • Standard MCT‑Software (basic configuration). • Advanced Diagnostics & Cloud (adds remote monitoring). | The purchase invoice will contain a license‑key or a “request‑key” link. | | 4. Receive the key | After payment, Danfoss will send the key via: • Email (encrypted PDF). • Direct download from the portal (requires login). | Keep the key in a secure location; it is your proof of entitlement. | | 5. Activate | Follow the on‑screen wizard in the MCT‑Software to enter the key. The software will confirm successful activation. | If you encounter an error, the portal usually offers a “re‑issue” option after verifying the hardware ID. | Tip: If you are an installer or integrator handling multiple units, consider purchasing a multi‑device license bundle . This reduces per‑unit cost and gives you a single master key that can be allocated per serial number through the portal. 4. Where the License Is Stored | Location | What’s stored | Access method | |----------|---------------|----------------| | On the controller (flash memory) | Encrypted flag indicating “licensed” and a hash of the key + hardware ID. | Not user‑editable; the controller validates the flag each power‑up. | | On the PC (local license file) | A copy of the key used for offline activation. | Usually C:\Users\<User>\Danfoss\MCT10\license.dat . Deleting it does not affect the controller’s license, but you’ll need to re‑enter the key if you reinstall the software. | | Cloud/portal (account‑wide record) | Central record of which serial numbers have been assigned which keys. | Useful for audits, renewals, and support tickets. | 5. Common License‑Key Issues & Troubleshooting | Symptom | Likely cause | Fix | |---------|--------------|-----| | “Invalid license key” message | • Typo when entering the key. • Key meant for a different model (e.g., MCT‑5). | Re‑type carefully; verify the key matches the MCT‑10 model. | | “License already in use” | The key is bound to another controller’s serial number. | Check that you are using the correct serial number; contact Danfoss support with proof of purchase for re‑issuance. | | “Cannot contact licensing server” (offline) | No internet, firewall blocks the Danfoss validation URL. | Use the offline activation file provided with the purchase (usually a .lic file you import). | | License disappears after firmware update | Firmware reset cleared the stored flag. | Re‑apply the key after the update; the software will re‑validate against the same hardware ID. | | Expired trial key | Time‑based trial reached its limit. | Purchase a full‑version key or request an extension (some trial extensions are possible for evaluation partners). |
