VL-220CZGV

Air quality has been proven to be the main parameter and influencer in comfort, productivity and fatigue. This is due to the high concentration of CO2 caused by insufficient air exchange. To live comfortably, each individual requires 400l of fresh air every hour. For this we present the Lossnay VL-220CZGV heat recovery ventilation system.

Characteristics

Energy EfficientThe highest energy saving in its class. (8.5W minimum input power) Saves heating and cooling costs by minimizing energy loss occuring during ventilation. 

At an ultra-quiet 14dB, it is the quietest product in its class. Blocks outside noise for a more comfortable environment.

Widely adjustable fan speed  

This model can operate at four main fan speeds. In addition, each speed has a range setting of approximately 25, 50, 75 and 100%, allowing optimum air volume control. When used in combination with the CO2 sensor or timer function, the air volume can be controlled according to conditions that realize better performance and reduce power consumption. 

Fan speed precise adjustment function  

Each main fan speed value can be further adjusted slightly. Use the PZ-61DR-E remote controller to adjust the speed. 1) Considering the total hours of Lossnay operation (filter clogging), the fan power can be adjusted automatically after a given period of time. 2) After the unit is installed, when if the air volume is slightly lower or higher than the desired airflow, it is possible to make fine adjustments. (Fan speed 4 is available only 1 down and 2 down)

To keep the Lossnay unit in optimal condition, clean dirt and dust from the filters and the drain pan periodically (at least once every six months or more, depending on the operating environment). 

Multi ventilation (power supply/exhaust) mode  

This mode allows the air supply/exhaust balance to be varied dynamically. The supply/exhaust balance can be selected to suit the usage environment.

The operation pattern for each day of the week. ON / OFF and air volume can be set using the weekly timer function (up to eight zones per day). This function contributes to enhanced energy saving operation. 

Free cooling mode  

During the summer season, the free cooling mode draws cooler outside air into the room. This mode contributes to reduced loads on air conditioning. For this operation, an optional bypass damper P-133DUE-E is required. The user is able to set the OA temp. depending on the preference between 10°C to 30°C
