CTM AH-8HN Air Handler / Fan Coil – 8,000 BTU – 230V – NMEA 2000

Boats running NMEA 2000 networks and needing 8,000 BTU of central chiller cooling get the same MFD integration in the CTM AH-8HN Air Handler, adding NMEA 2000 connectivity to CTM’s mid-capacity fan coil for control through Garmin Empirbus, OneHelm, and Raymarine YachtSense.

This dometic au-hv replacement nmea unit works as a drop-in swap for aging Dometic AU-HV air handlers while adding modern network integration — a meaningful upgrade for boats already running an NMEA 2000 backbone that want their HVAC system talking to the same displays as everything else onboard.

Why Choose the CTM AH-8HN

This unit carries CTM’s standard 2-year warranty against material and workmanship defects. Given the significant specification discrepancies identified above, confirming the actual chilled water connection size and minimum flow rate directly with CTM before ordering is strongly recommended.

What to Know Before Installing

• Confirm actual chilled water connection specifications directly with CTM given the discrepancies noted above
• Requires a matching CTM CW-series chiller as the central cooling source
• If replacing a Dometic AU-HV air handler, waterline connections need adapting from 1/2″ to 3/4″ — adapter included
• NMEA 2000 Starter Kit and temperature/humidity sensor are included with this unit
