The unit ensures a continuous supply of fresh and filtered air in the home. In winter, it heats the supply air, and in summer, it cools it, so the fresh air does not enter the room too cold or too hot. In addition, the unit removes excess moisture from the air.<\/p>\n<p>The unit is only 450 mm wide and is installed on the floor, so no space or work is required under the ceiling. Such a compact heat pump ventilation unit is well suited for apartments, terraced houses, and smaller private houses where the utility room is small.<\/p>\n<h3>Main advantages<\/h3>\n<ul>\n<li><strong>Only 450 mm wide<\/strong> \u2013 fits into a narrow niche, storage room, or technical room.<\/li>\n<li><strong>Heating and cooling<\/strong> \u2013 nominal heating capacity 3.96 kW and cooling capacity 3.67 kW.<\/li>\n<li><strong>Quiet<\/strong> \u2013 noise level only 37\/42 dB(A).<\/li>\n<li><strong>Hexagonal counterflow enthalpy heat exchanger<\/strong> recovers both heat and moisture from the exhaust air.<\/li>\n<li><strong>DC inverter compressor and EC fans<\/strong> operate energy-efficiently. You can choose between 10 speeds and 5 operating modes, and the COP is over 6.<\/li>\n<li><strong>Automatic bypass valve<\/strong> switches the device to 100% fresh air mode in suitable weather.<\/li>\n<li><strong>Operates at outside temperatures from \u221215 \u00b0C to +50 \u00b0C<\/strong>, complies with ErP 2018 requirements and uses R32 refrigerant.<\/li>\n<\/ul>\n<h3>Easy installation<\/h3>\n<p>The heat pump ventilation unit is connected to ducts via side horizontal connections with a diameter of \u00d8195 mm. Fewer bends mean lower pressure drops and quieter operation. The unit uses a standard 220 V single-phase power supply.<\/p>\n<h3>Smart leadership<\/h3>\n<p>The heat pump ventilation unit can be controlled via a touch-sensitive wall panel or the Smart Life app, available in the Google Play and App Store. The device supports Wi-Fi and Zigbee connectivity, as well as Amazon Alexa and Google Assistant. Air quality can be monitored using CO\u2082, humidity, TVOC, and PM2.5 sensors.<\/p>\n<p>Additional options are as follows:<\/p>\n<ul>\n<li>temperature and humidity control,<\/li>\n<li>weekly timer and scenarios,<\/li>\n<li>group management,<\/li>\n<li>RS485 interface,<\/li>\n<li>weather forecast-based management,<\/li>\n<li>automatic defrost,<\/li>\n<li>filter change and fault notifications.<\/li>\n<\/ul>\n<h3>Technical data<\/h3>\n<table>\n<tbody>\n<tr>\n<td>Nominal airflow<\/td>\n<td>400 m\u00b3\/h<\/td>\n<\/tr>\n<tr>\n<td>Extraction air volume (ventilation \/ heating-cooling)<\/td>\n<td>400 \/ 400 m\u00b3\/h<\/td>\n<\/tr>\n<tr>\n<td>External static pressure<\/td>\n<td>100 Pa<\/td>\n<\/tr>\n<tr>\n<th colspan=\"2\">Ventilation mode<\/th>\n<\/tr>\n<tr>\n<td>Temperature efficiency (heating \/ cooling)<\/td>\n<td>77% \/ 71%<\/td>\n<\/tr>\n<tr>\n<td>Enthalpy efficiency (heating \/ cooling)<\/td>\n<td>75% \/ 65%<\/td>\n<\/tr>\n<tr>\n<td>Input power \/ current<\/td>\n<td>185 W \/ 1.67 A<\/td>\n<\/tr>\n<tr>\n<th colspan=\"2\">Cooling<\/th>\n<\/tr>\n<tr>\n<td>Nominal \/ maximum cooling capacity<\/td>\n<td>3,67 \/ 3,91 kW<\/td>\n<\/tr>\n<tr>\n<td>Input power \/ operating current<\/td>\n<td>850 W \/ 4.61 A<\/td>\n<\/tr>\n<tr>\n<th colspan=\"2\">Fuel<\/th>\n<\/tr>\n<tr>\n<td>Nominal \/ maximum heating capacity<\/td>\n<td>3.96 \/ 4.21 kW<\/td>\n<\/tr>\n<tr>\n<td>Input power \/ operating current<\/td>\n<td>730 W \/ 4.04 A<\/td>\n<\/tr>\n<tr>\n<th colspan=\"2\">General information<\/th>\n<\/tr>\n<tr>\n<td>Noise level<\/td>\n<td>37\/42 dB(A)<\/td>\n<\/tr>\n<tr>\n<td>Toilet<\/td>\n<td>220 V, 1 phase, 50\/60 Hz<\/td>\n<\/tr>\n<tr>\n<td>Dimensions (L \u00d7 W \u00d7 H)<\/td>\n<td>1300 \u00d7 450 \u00d7 865 mm<\/td>\n<\/tr>\n<tr>\n<td>Weight<\/td>\n<td>130 kg<\/td>\n<\/tr>\n<tr>\n<td>Channel connection diameter<\/td>\n<td>\u00d8195 mm<\/td>\n<\/tr>\n<tr>\n<td>Vent height \/ base height<\/td>\n<td>40 \/ 40 mm<\/td>\n<\/tr>\n<tr>\n<td>Drain pipe<\/td>\n<td>G1\/2, 21 mm<\/td>\n<\/tr>\n<tr>\n<td>Refrigerant \/ quantity<\/td>\n<td>R32 \/ 320 g<\/td>\n<\/tr>\n<tr>\n<td>Operating temperature<\/td>\n<td>-15 to +50 \u00b0C<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Need a larger air volume?
