Operation of Remote Controller
Please read these instructions carefully before using this appliance.
1. Turn on the ON/OFF button.
2. The temperature display will read 40°C.
3. The priority indicator will illuminate.
4. Select hot water temperature by pushing or button on the remote controller.
5. Turn on the hot water tap or shower. The ``In Use´´ indicator will illuminate
after a short delay.
This indicator will remain illuminated until the hot water tap or shower
is turned o.

pushing or button located on the remote controller.
Remote Controller
Energy-saving Mode
If no data is adjusted within a period of approximately 5 minutes the display becomes
dim. This is energy-saving mode and not a failure.

Thermann Owner’s Guide

Priority Control (Change)
The temperature can only be controlled by the remote controller which has the
priority indication.
When the priority button is turned ON, that controller takes priority control over the
temperature settings. While hot water is being supplied, other remote controllers cannot
be turned o.
Whilst hot water outlets are open, transfer of ``priority´´ to other remote controllers
is not possible. This is safety feature.
HINTS FOR USING REMOTE CONTROLLERS FOR SAFETY AND ENERGY SAVINGS
1. Set the remote controller to a maximum of 42°C for normal bathroom use and to
prevent small children from scalding.
2. For kitchen and laundry use set the main remote controller to 60°C or the desired
temperature.
3. For showering, use settings between 37°C - 39°C and no cold water will be needed
to be mixed, and if other hot or cold water taps are used the temperature will be
maintained.
4. When bathroom remote controller is turned ON the temperature can be adjusted
between 37°C - 48°C.
Up to 50°C the temperature will increase by 1°C with each press of the UP/DOWN
buttons. The temperature can be adjusted continuously by keeping the button pressed.
Between 50°C and 75°C, the temperature is controlled by 5°C increments. The
temperature setting cannot be increased above 42°C while the hot water tap is open.
PLEASE NOTE: FOR TEMPERATURES ABOVE 50°C SCALDING CAN OCCUR
WITHIN SECONDS.
REMOTE CONTROLLER
Warning
Do not turn o the remote controller or change the water temperature while someone
is bathing or washing. That may result in scalds or burns.

of the THERMANN HOT WATER UNIT and the remote controller TEMPERATURE DISPLAY
INDICATOR.
The cause of the fault can be determined after checking the fault numbers display on the
Status Display of the THERMANN HOT WATER UNIT and the remote controller display.
Check the monitor whilst hot water taps are closed.
