3. CONTROL USING TWO REMOTE CONTROLLERS
Two remote controllers are available for control of either one unit or a group of units. Units operate according to the latest com-
mand from either of the two remote controllers.
However, before operation, be sure to set one remote controller for "main controller" and the other for "sub controller", using
dip switch SW17-7 of the remote controller.
3-1 How to set SW17-7
(1) For the main remote controller, turn SW17-7 OFF. (See Figure 5.)
(2) For the sub remote controller, turn SW17-7 ON.
3-2 Remote controller LCD indication
(1) The same indications always appear on both the main and sub remote con-
trollers, excepting in the timer operations.
(2) Timer operations can be set with either of the two remote controllers.
However, LCD indication appears only on the remote controller used for timer
settings.
(3) If both remote controllers are set for timer operation with different time-set-
tings, the timer operation of shorter remaining-time is effective.
(4) Self-diagnostic function is available with either of the two remote controllers.
If one of the remote controllers is used for the self-diagnostic function, the
other remote controllers displays the check mode.
If the self-diagnostic function is reset by either of the two remote controllers,
both remote controllers are reset.
