Operation
Bypass
The bypass ensures, should it be necessary, that there is no heat transfer between air extracted and supplied� This means that the
house cools down in a controlled and gradual manner� This function is active mainly in the summer� The bypass opens if the indoor
temperature rises above the set comfort temperature (set to 21.5 °C by default) and the outdoor temperature is above 10 °C�
As the comfort temperature in the sleep zone and the day zone can be different, it is possible to define different comfort tempera-
tures in zone-controlled systems, e�g�: 21�5° for the day zone and 18° for the night zone�
The unit contains 2 bypasses� Either only the right-hand bypass or only the left-hand bypass will serve, depending on the selection
of L or R in the initial installation screen� The software will always close the non-selected bypass�
