The unit has a built-in control unit that controls the operation of the
fans, the rotary heat exchanger and any electric heaters.
The unit is controlled via an external ISYteq Basic or ISYteq Touch 3.5
control panel (accessory), see page 6. The control unit should be in-
stalled in a suitable place.
After being adjusted, the unit can also be operated without a control
panel, but only in one operating mode.
The user can select between the following operating
modes:
“AWAY”
is used when there is reduced need for ventilation, e.g.
when occupants are on holiday
“HOME”
used for normal ventilation flow
“FORCED”
is used when there is a greater need for ventilation (au-
tomatically reverts to normal after 120 minutes)
Use the arrow button to switch operating modes (see figure 2). A LED
shows the current operating mode.
