<2> Setting the Water Temperature
The current water temperature will appear in the area
labeled .
How to Change the Temperature Setting
1. To lower the water temperature setting
Press the Set Temperature button .

• The settable ranges for the “Hot Water” and “Heating” modes are as
follows. *1, *2
Note:
*1 Available ranges vary depending on the type of unit connected.
*2 If the temperature ranges are restricted from the remote controller, the
settable ranges may be narrower than shown above. If an attempt is made
to set a value outside of the restricted range, the display will show a
message indicating that the range is currently restricted.
For information about how to set and clear the restrictions, refer to
[4]–2. (3) (page 49).
*3 Temperatures can be displayed in Celsius or Fahrenheit (factory setting:
Fahrenheit). For information about how to select °C or °F , refer to
[4]–4. (1) (page 49).
*4 If the target water temperature setting for the Heating mode has been set
to a temperature outside of the remote controller’s setting range (above
55°C) from the circuit board, any signal from the remote controller to
change the temperature setting will be ignored. If this happens, disconnect
the remote controller, set the target temperature to 55°C or below from the
circuit board, reconnect the remote controller, and then change the
temperature setting from the remote controller.
• Water temperature can be controlled based on the inlet or outlet
temperature.
* The water temperature range that can be displayed is between 0 °C to
100 °C. Outside this range, the display flashes either 0 °C or 100 °C.

the week.
• Each operation event can consist of any of the following: ON/OFF time
together with a temperature setting, ON/OFF time only, or temperature
setting only.
• When the timer reaches the preset time, the schedule event will take
place.
