capable of handling a maximum airflow rate of 25 m\u00b3\/h, alternating between supply and exhaust modes, with a useful internal volume of up to 25 m\u00b3. Equipped with an automatic air barrier damper in accordance with Regulation CE13141-8, a night mode (nighttime noise reduction), and a humidity control function. Sound pressure level at a distance of 3 m below 29 dB in accordance with the UNI EN ISO 3746:1997 standard; external noise attenuation of 44 dB; energy-efficient EC motor; power consumption below 3.35 W.

They can be installed through walls and are therefore particularly well-suited for renovations and partial renovations of rooms where mold is forming due to inadequate ventilation or where CO2-rich air needs to be removed. <\/span><\/p>\n<p><span dir=\"auto\">The maximum airflow rate for each unit is available in four sizes: 25, 50, 60, and 100 m\u00b3\/h, depending on the model. Since they operate 50% of the time in exhaust mode and 50% of the time in supply mode, the air exchange rate is reduced to 12, 25, 30, and 50 m\u00b3\/h, respectively. KERS+ heat recovery units ensure sufficient air exchange for rooms with floor areas of 9, 18, 22, and 37 m\u00b2, depending on the model (with an air exchange rate of 0.5 vol\/h and an interior height of 2.7 m).  <\/span><\/p>\n\n<p>&nbsp;<\/p>\n<p><span dir=\"auto\">The machine is equipped with an EC motor fan with energy recovery, which is capable of reversing the airflow in the recovery unit and operates in two phases:<\/span><\/p>\n<p><strong><span dir=\"auto\">Stage 1:<\/span><\/strong><\/p>\n<p><span dir=\"auto\">The fan draws hot air from the room and sends it through the heat recovery unit to the outside. This cools the air while retaining the heat it contains. <\/span><\/p>\n<p><strong><span dir=\"auto\">Stage 2:<\/span><\/strong><\/p>\n<p><span dir=\"auto\">The fan reverses the airflow and draws in cool air from outside. When this air comes into contact with the heat recovery unit, it is warmed before entering the room. <\/span><\/p>\n<p><span dir=\"auto\">The remote control included as standard equipment allows you to:<\/span><\/p>\n<ul class=\"checklist\">\n<li><span dir=\"auto\">Use Kers+ only in extraction mode or only in input mode.<\/span><\/li>\n<li><span dir=\"auto\">Adjust the fan speed according to the desired humidity level.<\/span><\/li>\n<li><span dir=\"auto\">Setting up automatic night dimming<\/span><\/li>\n<li><span dir=\"auto\">Set up automatic ventilation based on three humidity thresholds<\/span><\/li>\n<li><span dir=\"auto\">To quickly remove unpleasant odors, activate the boosted suction function at maximum speed for 30 minutes.<\/span><\/li>\n<li><span dir=\"auto\">Turn Kers+ on and off.<\/span><\/li>\n<\/ul>\n<p><span dir=\"auto\">Using the device&#8217;s buttons, you can:<\/span><\/p>\n<ul class=\"checklist\">\n<li><span dir=\"auto\">Set three operating speeds<\/span><\/li>\n<li><span dir=\"auto\">Configuring heat recovery and activating automatic nighttime dimming<\/span><\/li>\n<li><span dir=\"auto\">Displays operating speed and the need to clean the filters using LEDs<\/span><\/li>\n<\/ul>\n<p>To install the recovery unit, drill a through-hole in the perimeter wall for KERS+ 25\/50\/60\/100 Wi-Fi-ready devices, with a minimum diameter of 102\/162\/162\/202 mm, at a 2\u00b0 or 3\u00b0 angle outward. The channel can be adjusted according to the actual thickness of the wall. All that is required is a 110\u2013230 Vac power source using a 2&#215;1.5 mm\u00b2 cable. Control is via the device\u2019s retractable buttons, the remote control included in the package, a free remote control adapter, or Wi-Fi.   <\/p>\n<p><strong><a
