Setting Hot Water Temperature

Use the  

buttons to adjust

the temperature.

(Eg.: 40°C)

Press the

ON/OFF

button to turn it

“On”.

When using RCM3211

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.

Here

*  The 

ON/OFF

 is lit.

*  When Circulation is on, the 

symbol blinks and circulation
mode starts automatically.
