Simple timer .
For information about how to set the Function Selection of remote controller, refer to section "Installation Manual", item [5]–3 (2).

• If two remote controllers are connected to one machine or group and the timer is used, set the timer only in one remote controller, and set "Timer disabled" in the other. The
system will not operate correctly if two different timers are set in the two remote controllers.

• When the current time reaches a time set at this timer, the Lossnay unit carries out the action set by the timer.
