Replacement & Compatibility FAQ
Q: Can I replace RM7890A1015 with RM7890A1014?
A: In most cases yes — both are 7800 Series modules sharing the same subbase footprint. Verify firmware revision compatibility with your system integrator.
Q: Is the RM7890A1015 compatible with 240 VAC systems?
A: No. The A1015 suffix designates 120 VAC / 60 Hz. For 240 VAC applications, consult Konmask.com for the correct variant.
Q: Can I use a Siemens LME series module as a replacement?
A: Siemens LME modules are not direct plug-in replacements — they require different wiring bases and scanner inputs. Cross-brand substitution should only be performed by qualified combustion engineers.
Q: Does Konmask.com provide warranty on this product?
A: Yes. We offer a 12-month warranty against manufacturing defects on all genuine OEM parts. Contact support@konmask.com for warranty claims.
Q: How do I verify authenticity of my Honeywell module?
A: Check the holographic label, date code, and serial number. Konmask.com provides documentation of supply chain traceability upon request.
