2. Wiring
Description
The operation of the indoor
unit can be forcedly stopped
when opening the window by
mounting an outside switch
(Procured locally) to the
window and connecting it to
the indoor P.C. board via a
relay.
3. Operation
• While the window closes (CN64 is opened), the indoor unit
performs the usual operation.
• While the window opens (CN64 is short-circuited) and the
indoor unit is operating, the indoor unit stops the operation.
• If a signal is sent from the remote controller while the window
opens (CN64 is short-circuited), the indoor unit ignores the
signal and does not operate. In this case, the receiving sound
“pip” goes off for five times.
• While the window opens, all the operation modes are not used.
• If closing the window again when the window opened and the
indoor unit stopped the operation, the indoor unit continues the
operation stop status and cannot be reset automatically.
• The lead wire, which connects the indoor P.C. board and the
relay, should be long within 2m. If using a longer wire or if not
using a relay, a malfunction may occur.
• The lead wire (length: 500mm) attached with connector, which
connects it with CN64 is prepared as article sold separately.
