Chapter 3 – Basic Cabinet Operation
3.1 Sash Window Operation
3.1.1 Sash Window State
3.1.2 Operating Motorized Sash Window (Only for BSC with motorized sash window)
The motorized sash uses a “push and hold” mechanism, so if you remove your finger from the button the sash
will stop immediately – this is a safety feature to control the closure and prevent anything getting trapped in
the aperture as the sash descends.
Lower Sash from Fully Open Position
When the sash is fully open, pressing the down button and holding it will cause the sash to move to the Safe
Height setting and stop. If the fluorescent lights are on as the sash descends, they will stay on as long as the
sash stops in the Safe Position. If you release the button before the sash has reached Safe Position the lights
will switch off automatically.
Lower Sash from Safe Height Position
When the sash is at safe operating height pressing the down button and holding it will cause the sash to move
down to the fully closed position and stop. If the fluorescent lights are on as the sash descends, they will
switch off automatically as soon as the sash reaches fully closed. If you release the button before the sash has
reached the fully closed position the lights will switch off automatically
Raise Sash from Fully Closed Position
When the sash is fully closed, pressing the up button and holding it will prompt the user to input the password
to turn on the fan. If the password is correct, if it was on fan will turn on and the sash will move up to the Safe
Height setting and stop.
Raise Sash from Safe Height Position
When the sash is safe operation position, pressing the up button and holding it will cause the sash to move up
to the fully open position and stop. If the fluorescent lights are on as the sash rises, they will stay on as long as
the sash is allowed to fully open. Stopping the sash midway will cause the lights to switch off automatically.
