Turn on hot water.

Previous set temperature

(Eg.: 40°C)

Whenever using the hot water, such as when using the shower, check the temperature shown on the remote controller first, and then test the hot water temperature by hand.

Be especially careful if using hot water after previously using water at 60°C or above to prevent scalding.

While the shower is being used, no one other than the user should change the temperature, the power switch must not be turned “off”. (when using sub remote controller.)

WARNING

This is to prevent scalding if the temperature rises. Conversely, if the temperature drops or the power switch is turned “off”, the user may be upset when the water suddenly becomes much colder.

• When a high temperature is set, the readout on the right is shown.

• Please check the temperature displayed before using any hot water. Be especially careful using any hot water after any previous setting of between 60 - 80°C.

• If the power switch on the remote controller is turned “on”, the remote controller has priority in adjusting the temperature.

• When the temperature can be adjusted (console has priority), the display screen is shown as per right.

• If the temperature cannot be adjusted, turn the power switch to “off”, and then turn it “on” again.

• Hot water temperatures are approximations, and may differ from actual temperatures depending on external factors, such as the season and length of piping involved.

• When low temperatures are set (for washing dishes, etc.), if the ambient water temperature is already quite high, it may be difficult to ensure the resultant water temperature is as per the setting.

• When the hot water temperature is adjusted using thermostat-controlled water mixing valves, set the temperature on the remote controller to about 10°C higher than that required to ensure the appropriate temperature.

When setting high temperatures (60 - 80°C);

(Eg.: 60°C)

Temperature display flashes for about 10 seconds to indicate high temperature.

Please switch to the priority setting if the temperature cannot be adjusted (when an additional remote controller is attached).

Circulation Operation

When using RCM3211 Display of on the remote controller

When reducing the temperature setting from very high during

instant hot water operation, be wary of the actual temperature.

To prevent scalding. Even after the temperature is changed, very hot water remains within the pipe.
