Samsung EHS Mono HT Quiet 8 kW

Compatibility

Compatible with EpiSensor Edge through a Samsung MIM-B19N Modbus module

Samsung documents the outdoor/control-kit pairing and a separate MIM-B19N/B19NT EHS register table on Modbus RTU. Edge reads the module through a ZMB-31 or the Gateway’s serial interface: communication status, unit type, water-in, water-out and hot-water temperatures. An EpiSensor ZEM on the unit’s supply provides the electrical input for COP.

Check accessory fit and wiring with the Samsung installer, then record the installed controller, MIM-B19N revision and tracked EHS device address. The following addresses are best-effort candidates from DB68-07538A-03 and should be compared with the local controller. PV, Smart Grid Ready and other control writes require their own commissioned design.

Specifications

Samsung's 2026 installation manual distinguishes the single-phase AE080BXYDEG from the three-phase AE080BXYDGG and higher-capacity models. For the 8 kW unit it specifies 220-240 V, 50 Hz supply, 2.7 kg R32, 1-inch water connections, 126 kg net mass and a 1,270 × 1,018 × 530 mm enclosure.¹

Interface

Documented measurements and integration boundaries for EHS Mono HT Quiet 8 kW.

• The February 2026 outdoor manual lists AE080BXYDEG as 1-phase 220-240 V, 50 Hz, using 2.7 kg of R32. It lists MIM-E03EN and MIM-E03CN control kits; its certification table ties AE080BXYDEG/EU to both kits for space heating only.
• Samsung's product brochure shows a PV contact and Smart Grid Ready function with the MIM-E03EN kit. These are installer-configured control contacts, not a live PV production meter, heat meter or published software dispatch API.
• The MIM-B19N/B19NT manual gives Modbus RTU settings of 9600 baud, 8 data bits, even parity and one stop bit. Its Samsung R1/R2 side uses the proprietary Control Layer Protocol; the A/B side serves Modbus. The installer must establish the correct Samsung bus attachment for the fitted system.
• For tracked EHS device address IU, the module's table uses a base PDU address of 50 + 50 × IU. Water-in temperature is base + 15, water-out is base + 16 and hot-water temperature is base + 25. Read-only temperature values are expressed as Celsius × 10. For IU 3, these candidates are 215, 216 and 225; a raw positive value of 400 represents 40 °C.
• Communication status is base + 0: bits 0, 1 and 2 indicate present, correct type and ready, while bit 3 indicates a communication error. Unit type at base + 1 has EHS codes 115-117 in its lower byte. The manual says registers start at zero and retain their last value after a lost Samsung link, so check tracking and freshness before interpreting temperatures.
• SmartThings operation is optional and requires Samsung's supported controller, Wi-Fi kit, network and account. An app connection is not evidence of a local third-party data endpoint.
• An 8 kW nameplate and a nominal COP do not establish measured heat delivery or seasonal performance. Use a hydronic heat meter and electricity metering that includes every compressor, pump, booster and backup load inside the stated COP boundary.

Setup

1. Identify the whole Samsung system

   Read the outdoor AE080BXYDEG/EU nameplate and the actual MIM-E03EN/CN or ClimateHub controller label. Capture firmware, optional Wi-Fi and any auxiliary heater arrangement.

2. Trace the hydronic and electrical boundaries

   Record flow and return circuits, circulation pumps, domestic-hot-water storage, booster/backup heater feeds and the point of grid connection. Decide which loads and heat flows a performance metric will include.

3. Check the fitted Modbus module

   Have the Samsung installer check MIM-B19N/B19NT accessory fit and its bus connection. Record the module's DIP/rotary slave address, tracked EHS address and revision. Configure the read client for 9600 baud, 8E1 and inspect module tracking before selecting points.

4. Try the published EHS read candidates

   Use the table's base address 50 + 50 × IU for the actual tracked EHS address. Start with communication status and unit type, then water-in at base + 15 or water-out at base + 16 using FC04. Compare temperatures divided by 10 with the Samsung controller. If a point is absent, check tracking, the device address and controller configuration rather than guessing a different equipment map.

5. Meter heat and power independently

   Install or identify suitable thermal and electrical meters at the chosen boundary. Align intervals and sign conventions; use controller temperatures or operating states to explain operation, not to substitute for measured delivered heat.

6. Preserve commissioned controls

   Keep PV contact, Smart Grid Ready, frost protection, hot-water priority and heater operation under the approved system design. A flexibility proposal needs documented permissions, limits and fail-safe behavior before control.

Common questions

Where should I start with Modbus monitoring?

Start at a compatible, installer-fitted MIM-B19N/B19NT module that tracks the controller as EHS. Samsung's table provides status, unit type and temperature candidates using the tracked device address. This guide gives that best-effort starting map; compare it with the controller before saving the monitoring configuration.^1, 4

Does the PV contact report solar generation?

No. The brochure shows a PV contact as a control input on the MIM-E03EN system. A separate PV inverter or meter supplies generation data, and the contact's commissioned meaning needs its kit instructions.²

Does Smart Grid Ready make the heat pump dispatch-ready for a VPP?

The brochure names Smart Grid Ready, but does not establish remote commands, acknowledgement, override priority or fail-safe behavior for this installation. A VPP design needs those controls specified and accepted separately.²

Can Samsung's nominal COP prove operating efficiency?

No. The brochure's nominal COP is a laboratory operating-point figure. A site COP needs delivered heat and the included electrical inputs measured across the same period and a declared boundary.^1, 2
