What should you do if an external device is connected to the Lossnay’s “On/Off” function?

If an external device is connected the “On/Off” function of this device, it will also control the Lossnay operation. If you would like to turn ON the Lossnay alone while the external device is OFF, operate it by the Lossnay remote controller. The fan speed is on Fan speed 3 or Fan speed 4. The ventilation mode is “Auto Ventilation Mode”. If 2 remote controllers are used, the last controller to be used has priority.

What is the automatic ventilation mode and how does it work?

The automatic ventilation mode automatically provides the correct ventilation for the conditions in the room. If the air outside is cooler than the air inside the building during the cooling season, “By-pass” ventilation will draw in the cooler outside air and reduce the cooling load on the system. “By-pass” ventilation can be used to release hot air from inside the building that has accumulated in buildings during the hot summer season. During cold season, fresh air can be drawn in and used as is to cool rooms where the temperature has risen due to the use of office equipment. When set to auto ventilation mode while using the pre-heater function, the outdoor temperature may be detected as higher and the mode may change to by-pass mode, even in winter. In the case of “By-pass” ventilation, the supply air temperature slightly rises more than the outside air temperature because of the heat effect around the ducts or the unit motors.

---

What is the “BY-PASS VENTILATE” setting?

The fresh air passes through the Lossnay cores and the return room air is exhausted direct. Lossnay By-pass ventilate is normally operated during the spring/autumn season.

---

What is the “LOSSNAY ENERGY RECOVERY VENTILATE” setting?

Both fresh air supply and return air pass through the energy recovery cores. Energy recovery ventilation makes the fresh air temperature close to the indoor temperature in the winter and the summer season.

---
