6.2.1.2. Open/ Close/Off
The open\close\off switch is used for manual control of the curtains.

the manual position. At other times, this switch is not operable, thus

“CLOSE” position of the switch allows current to flow to the PVR-H,
directing power to the “close” windings of the curtain machine. The
“OFF” position does not allow current to the PVR-H, but is not a safe
electrical disconnect for the curtain machine.
