3. CONTROL USING TWO REMOTE CONTROLLERS

Two remote controllers can be used to control either one unit or a group of units. Units operate according to the latest com- mand from either of the two remote controllers.

Before operation, be sure to set one remote controller as the “main controller” and the other as the “sub controller”, using dip switch SW17-7 of the remote controller.

3-1 How to set SW17-7 (See Figure 5.)

(1)For the main remote controller, turn SW17-7 OFF.

(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 controllers, except during 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-settings, the timer operation with the shorter remaining-time is effective.

(4)Self-diagnostic function is available with either of the two remote controllers. If one of the remote con- trollers is used for the self-diagnostic function, the other remote controller displays the check mode.

If the self-diagnostic function is reset by either of the two remote controllers, both remote controllers are reset.

4. REMOTE ON-OFF AND INDIVIDUAL REMOTE CONTROLS

This method is available to control one unit or any number of units.

The following operations are available by connecting a relay, a timer adapter (PAC-SA89TA-E), and a remote ON/OFF switch to the system. Timer adapter is an optional part. Other parts are available on the market.

(A)To start all units in order by remote ON-OFF switch

(B)To stop all units simultaneously by remote ON-OFF switch

(C)To switch between the remote ON-OFF control and the individual remote control
