Operation Instructions
11
[Notes]
When “Weekly timer”, “Preset mode”, “Clock timer” “Temp. timer” have been set at the same time, then the latter
takes the priority.
This setting is valid only when the unit is turned on.
Under the “Cool” or “Cool + Hot water” mode, the setting targets at “WT-Cool”; while under the “Heat” or “Heat +
Hot water” mode, the setting targets at “WT-Heat”.
When start time of period 2 is the same as that of period 1, then the former takes prevalence.
”Temp.timer” is judged based on timer.
During this setting, when temperature is set manually, then this setting will take prevalence.
Under the “Hot water” mode, this function will be reserved.
This function will be memorized upon power failure.
2.2.12 Emergen. Mode
[Operation Instructions]
1. At the function setting page, set the mode to “Heat” or “Hot water”.
2. At the function setting page, select “Emergen.mode” and set it to “On” or “Off”.
3. When “Emergen.mode” has activated, the corresponding icon will appear at the upper side of the menu page.

[Notes]
The emergency mode is allowed on conditions that there is some error or protection and the compressor has
stopped at least for three minutes. If the error or protection has not been recovered, the unit can access to the
emergency mode through the wired controller (when the unit is off).
Under the emergency mode, “Hot water” or “Heat” cannot be performed at the same time.
When the running mode is set to “Heat”, if “Other thermal” or “Optional E-Heater” is set to “Without”, the unit
will fail to access to the “Emergen. mode”.
When the unit performs “Heat” under “Emergen. mode” and the controller detects “HP-Water Switch”, “Auxi.
heater 1”, “Auxi. heater 1”, and “Temp-AHLW”, this mode will quit at once. In the same way, when errors mentioned
above occur, “Emergen. mode” cannot be activated.
When the unit performs “Hot water” under “Emergen. mode” and the controller detects “Auxi.-WTH”, this mode
will quit at once. In the same way, when errors mentioned above occur, “Emergen. mode” cannot be activated.
When this function has been activated, “Weekly timer”, “Preset mode”, “Clock timer”,and “Temp timer” will be
deactivated. Beside “On/Off”, “Mode”, “Quiet mode”, “Weekly timer”, “Preset mode”, “Clock timer”,and “Temp timer”
operation are unavailable.
Under “Emergen. mode”, the thermostat does not work.
This function can be activated only when the unit is turned off. If dosing so with the unit keeping “On”, a window
will pop up, saying “Please turn off the system first!”.
“Floor debug”, “Disinfection”, and“Holiday mode” cannot be activated at the same with this function. When
doing so, a window will pop up, saying “Please disable the emergen. mode!”.
Upon power failure, “Emergen. mode” will back to “Off”.
