Suitable for residential buildings under reconstruction as a replacement for vacuum ventilation using fans or for new construction where constant ventilation without heat leakage is required.
- ease of assembly - easy to control - simple maintenance - quiet operation - economical EC motor
The unit operates in two 60 second cycles:
I cycle The warm air removed from the room flows through the heat exchanger and transfers the heat. After 60 seconds of heating the heat exchanger, the ventilation unit switches to supply mode.
II cycle Fresh, cool outdoor air flows through the heat exchanger. The air is heated by the heat that was previously accumulated in the heat exchanger. After 60 seconds, the fan switches back to suction mode and the cycle repeats.
Control The unit is controlled using a remote control. When you turn On/Off on the remote control, the fan starts at the speed at which it was turned off. You have a choice of 2 fan speeds. The speed at which the fan operates is indicated by a colored LED on the front panel of the indoor unit. The first (lower) speed corresponds to the green color, the second (higher) speed corresponds to the blue LED color. Changing the remote control commands is confirmed by a short-term decrease in the brightness of the LED diode. The operation of the unit can be controlled using a humidity sensor. Using the included plastic screwdriver, set the desired humidity level on the potentiometer in the range of 60-90%. If the humidity in the room exceeds the set value, the unit will automatically switch to the second (higher) speed and work until the humidity returns to normal. After venting the moisture, the unit returns to its previous operating mode. At high outdoor air humidity, the recuperation unit can switch to the second (higher) speed due to the humidity sensor being triggered. If such switching is undesirable, temporarily switch off the humidity sensor. Night mode switches the fan to the first (quieter) speed and dims the backlight of the operating light for 8 hours. In this mode, the unit does not respond to switching speeds and triggering the humidity sensor. After this time, the fan will return to the previous operating mode. You can turn off night mode at any time using the remote control.
