## LG Therma V R290 1/3-phase Hydrobox indoor unit 6kW/9kW


The LG Therma V R290 Hydrobox (LG-HN16XAHC.NK1) is a compact indoor unit for monobloc heat pumps in residential and light-commercial projects. Within our range of **[heat pumps](https://www.estg.eu/en-gb/assortment/heat-cool/heat-pumps)** from **[LG Electronics](https://www.estg.eu/en-gb/brands/lg-electronics)**, this wall-mounted unit manages central control and indoor hydraulic distribution. The system features switchable electric back-up heating and manages flow temperatures and domestic hot water preparation via a built-in three-way valve. Because the connection to the monobloc outdoor unit is fully hydronic, you install the complete system without an F-gas certificate.


### Advantages of the LG Therma V R290 Hydrobox indoor unit for installers


- **Switchable back-up heater**: flexible connection to a 1-phase supply up to 6 kW or to a 3-phase supply up to 9 kW depending on the distribution board
- **Wide system compatibility**: pairs directly with 1-phase outdoor units from 5 kW to 9 kW and 3-phase outdoor units from 9 kW to 16 kW
- **Pre-assembled hydraulic components**: equipped with a 12-litre expansion vessel, a three-way valve and an electric heater for rapid assembly
- **Fully hydronic connection**: requires no handling of refrigerant pipework, allowing installation without an F-gas certificate
- **Built-in Wi-Fi and touchscreen**: equipped with Wi-Fi for the LG ThinQ app and a 6.8-inch colour touchscreen as standard
- **Quiet operation**: silent in the home with a sound pressure level of only 31 dB(A) at 1 metre distance


### Universal application with switchable electric back-up heating


The letter X in the model code indicates the flexible back-up heater that you adapt to the available mains connection. You connect this heater to a 1-phase circuit up to 6 kW or to a 3-phase supply for 9 kW heating output. This allows you to combine the same indoor unit with 1-phase outdoor units as well as 3-phase outdoor units. This reduces your stock holding and keeps component selection straightforward. The system delivers heating water up to 75°C and heats domestic water in combination with a separate cylinder up to 80°C.


### Complete internal hydraulics and fast installation


This indoor unit saves valuable installation time in the plant room. Components such as the 12-litre expansion vessel, the automatic air vent and the three-way valve are factory integrated. The bottom features clear 1-inch connections for the heating circuit, domestic hot water and pipework to the outdoor unit. Commissioning runs smoothly thanks to the integrated 5-step setup wizard on the 6.8-inch touchscreen. Built-in Wi-Fi connects the system directly to the LG ThinQ app for remote control.
