EHS Mono HT Quiet

EHS Mono HT Quiet is Samsung’s R32 high-temperature monobloc range. Its outdoor codes use AE080BXY, AE120BXY and AE140BXY prefixes for the 8, 12 and 14 kW capacity classes.

Output and electrical forms

This entry maps the six current outdoor-unit codes:

Capacity class	Single-phase outdoor unit	Three-phase outdoor unit
8 kW	AE080BXYDEG/EU	AE080BXYDGG/EU
12 kW	AE120BXYDEG/EU	AE120BXYDGG/EU
14 kW	AE140BXYDEG/EU	AE140BXYDGG/EU

DEG identifies the 220–240 V single-phase version and DGG identifies the 380–415 V three-phase version. Leaving-water temperature reaches 70°C, while the 8 kW model operates in heating mode down to -30°C.

These limits do not establish the useful output or efficiency at a project’s design point. The exact performance table is needed at the design outdoor temperature and selected heating-water temperature.

Normal and quiet-mode sound figures

The 8 kW outdoor unit has sound figures of 42 dB(A) pressure and 56 dB(A) power. Its four-step quiet mode can reduce sound pressure to 35 dB(A). Those figures use different operating conditions and should not be treated as interchangeable.

The planning or MCS noise calculation uses the declared sound power for the exact outdoor unit, its position and nearby reflective surfaces. A quiet-mode figure is relevant only where the commissioned control settings and design assumptions match it.

System and certification records

Mono HT Quiet keeps R32 in the outdoor unit and connects hydraulically to a Samsung control kit or indoor package. This entry does not prescribe a control-kit, ClimateHub or cylinder pairing.

Exact combinations containing all six outdoor-unit codes were present in the MCS Product Directory on 23 July 2026. Several control-module and ClimateHub pairings exist, so the exact complete combination must be checked against the current MCS record and Samsung compatibility material.
