Replacement & Compatibility FAQ
Q: Can I use 51403427-150 instead of 51403427-175?
A: In most cases yes, but firmware versions must match. We recommend testing in a non-critical loop first or consulting Honeywell’s compatibility matrix.
Q: Is this module available new from stock?
A: Availability varies. Contact us for current stock status — we source globally and can typically fulfill within 3–10 business days.
Q: Do you provide a warranty?
A: Yes. New modules carry manufacturer warranty. Refurbished and surplus units carry a 90-day Konmask functional warranty.
Q: Can you help identify the correct LIM revision for my system?
A: Absolutely. Share your system serial number or configuration report and our engineers will confirm the correct part.
Q: Do you ship internationally?
A: Yes — we ship to 50+ countries with full export documentation. DDP, DAP, and EXW terms available.
