Operation Control Function By The Wired Remote Controller - Mitsubishi Heavy Industries FDTC50ZHXV Technical Manual

(3) Operation control function by the wired remote controller

(a) Switching sequence of the operation mode switches of remote controller
(b) [CPU reset]
This functions when [Inspection] and [Grill Up/Down] buttons on the remote controller are pressed simultaneously. Operation
is same as that of the power supply reset.
(c) [Power failure compensation function]...Electric power supply failure
• This becomes effective if "Power failure compensation effective" is selected with the setting of remote controller function.
• Since it memorizes always the condition of remote controller, it starts operation according to the contents of memory no
sooner than normal state is recovered after the power failure. Although the auto swing stop position and the timer mode are
cancelled, the weekly timer setting is restored with the holiday setting for all weekdays.
After recovering from the power failure, it readjusts the clock and resets the holiday setting for each weekday so that the
setting of weekly timer becomes effective.
• Content memorized with the power failure compensation are as follows.
Note (1) Items ➅ , ➆ and ➇ are memorized regardless whether the power failure compensation is effective or not while the setting of silent mode is cancelled
regardless whether the power failure compensation is effective or not.
At power failure – Operating/stopped
➀
If it had been operating under the clock off timer mode, time timer mode, the state of stop is memorized. (Although
the timer mode is cancelled at the recovery from power failure, the setting of weekly timer is changed to the holiday
setting for all weekdays.)
Operation mode
➁
Airflow volume mode
➂
Room temperature setting
➃
Louver auto swing/stop
➄
However, the stop position (4-position) is cancelled so that it returns to Position (1).
"Remote controller function items" which have been set with the remote controller function setting ("Indoor
➅
function items" are saved in the memory of indoor unit.)
Upper limit value and lower limit value which have been set with the temperature setting control
➆
Clock timer and weekly timer settings (Other timer settings are not memorized.)
