CAUTION:
- The control timer has a built-in back-up
battery and the clock function is available
within 2 weeks in case of power failure.
If the power failure continues more than
2 weeks, set the present time again.
- The RUN indicator is turned on at ON
time and turned off at OFF time.
In case that that the indoor unit operation
is started or stopped by the remote
control switch or the central station used
together with the timer, the RUN
indicator is not changed.
- The flickering of the RUN indicator
shows the abnormal condition of the
Timer.
Check to ensure that the wiring
connection and the setting of dip
switches are correct.
In the case that the RUN indicator is still
flickered after checking, contact your
distributor or dealer of HITACHI.
CAUTION:
- It may take approximately 15 seconds to
start (or stop) operation after ON time (or
OFF time) according to the controller used

stopped during the setting mode condition.
After the completion of setting, set the
Timer at the monitor mode. (After 3
minutes with leaving the Timer at the
setting mode, the Timer is changed to the
monitor mode automatically.)
- In the case that the Timer is used with the

Station" for details.

setting is not available. After recovery the
