Specifications

RV-19-DC-R32 technical data

Heating capacity and COP at A7/W35: outdoor air 7 °C, water outlet 35 °C. Both fall as the outdoor temperature drops or the water temperature rises. Cooling figures are the manufacturer's nominal ratings. A = outdoor air temperature, W = water outlet temperature, both in °C.

Hydraulics

Water side

Hydraulics
Water connection	DN32
Nominal water flow	2.8 m³/h
Minimum water flow	35 L/min
Minimum system water volume	70 L

Nominal water flow is the rated heating output at a 5 K flow/return difference: 16.1 kW ÷ (1.163 × 5 K) ≈ 2.8 m³/h. The minimum system water volume protects against short cycling and supplies the energy needed during defrost. Where zones can close and the open circuit falls below 70 L, a buffer tank or bypass is required.

Electrical

Supply and protection

Electrical
Power supply	230 V / 50 Hz
Maximum power input	5.00 kW
Maximum current	23 A
Recommended breaker	25 A
Indicative supply cable	4 mm²

30 mA high-speed RCD recommended. Cable size and breaker are indicative guidance only. The final installation must follow the local electrical code, taking into account cable type and installation method, ambient temperature, voltage drop, protective-device coordination and any auxiliary loads.

Controls and technology

What is built into every RV model

Mitsubishi DC inverter compressor

Variable compressor speed follows the heat demand instead of switching on and off at full power.

SG Ready

A two-input energy-management interface: an energy manager or PV system can lock, release or boost operation.

Wi-Fi and 7-inch touchscreen

Multilingual touchscreen control of heating, cooling, hot water and schedules, with remote monitoring and control over Wi-Fi.

Smart Home Ready

Integration through the controller's available interfaces and the SG Ready inputs; the automation architecture decides what is possible.

Automatic defrost

Clears frost from the outdoor coil in cold, humid weather to restore heat transfer.

Cold-climate operation

Heating operation down to −20 °C outdoor, with capacity and COP that change with conditions.

R32 refrigerant

Single-component refrigerant with a GWP of 675, a third of R410A's.

Applications

Where the RV-19-DC-R32 fits

One monobloc unit supplies space heating, space cooling and domestic hot water. Hot water takes priority through a diverting valve, not in parallel with the heating circuit.

Underfloor heatingLow flow temperatures give a heat pump its best seasonal efficiency.

Fan coilsOne set of terminals for heating in winter and cooling in summer.

Low-temperature radiatorsOutput depends on water temperature and radiator size, so check the numbers first.

Domestic hot waterA cylinder on a diverting valve, with hot water priority.

Solar PV integrationStore surplus PV generation as heat, signalled through SG Ready.
