Wireless Control Switch With Automatic Control; Wired Three-Position Switch - Heatrae Sadia ADVANCE Installer Manual

4.4. Wireless control switch with automatic
control/timer
This wireless control switch allows you to select the ventilation
speed (capacity) of the unit:
Auto setting, automatic mode; sensor-based
control (CO , RV and/or PIR). The capacity is
2
regulated between low and high.
Level 1, low speed; when one person is
present during the day or night, or when no-
one is present.
Level 3, high speed; during cooking,
showering or bathing, or when a lot of people
are present.
Timer; high speed for switching the unit to
high speed for an adjustable period.
High speed remains active for a maximum of 24 hours, after which
the unit switches back to medium or low speed, depending on
which of these was selected last.
Once the timer has run out, the unit switches back to the last
selected speed before the timer was started, unless that was high
speed. In that case the unit switches back to medium or low speed,
depending on which of these was selected last.
The duration of the timer can be set as follows:
Press the timer button once: 10 minutes at high speed
●
Press the timer button twice: 20 minutes at high speed
●
Press the timer button three times: 30 minutes at high speed.
●
The timer can be stopped at any time by pressing the button for
low speed, high speed or automatic mode.
Note
If sensors have been paired with the ventilation unit, low speed
or high speed will remain active for a maximum of one day, after
which automatic mode will be activated.

4.5. Wired three-position switch

This control switch is connected directly using connecting wires.
The wired control switch can be combined with one or more
wireless control switches.
Using the wired three-position switch, the unit can be put into three
different ventilation modes (capacities) by turning the switch:
Level 1, low speed; when one person is
1
present during the day or night, or when no-
one is present.
Level 2, medium speed; during the day or
2
night when more than one person is present.
Level 3, high speed; during cooking,
3
showering or bathing, or when a lot of people
are present.
High speed remains active for a maximum of 24 hours, after which
the unit switches back to medium or low speed, depending on
which of these was selected last.
Note
If the wired control switch is combined with a wireless control
switch, there is a risk that the ventilation unit may be set to high
by the wired switch and then to low by the wireless switch. In this
case, the wired switch will indicate high speed when the
ventilation unit is actually running at low speed.
In order to re-activate the wired control switch in this situation,
you should first switch it to another speed.
Note
For ventilation units with which sensors have been paired (CO
RV and/or PIR), Mode 2 operates as an automatic mode.
Note
If sensors have been paired with the ventilation unit, low speed
or high speed will remain active for a maximum of one day, after
which automatic mode will be activated.
