3.1 Operation

D0000071074

1 Display

2 Progress bar displayed during data transmission

3 Temperature setting OFF, 20°C - 60°C (if the instantaneous

water heater is used to supply a shower) in 0.5°C increments

using the "+" and "-" keys

4 Memory keys "1" and "2"

Shortly after the last setting has been made, the wireless remote

control goes into energy saving mode and the display is switched

off.

The most recently transmitted temperature is still retained in en-

ergy saving mode.

Function of memory keys "1" and "2"

When either of the memory keys are pressed, the temperature

saved for them is brieﬂy displayed. If no other key is pressed within

the next second, the temperature displayed is directly transmitted.

Function keys "+" and "-"

When the "+" or "-" keys are pressed, the most recently transmitted

temperature is brieﬂy displayed. If no other key is pressed within

the next second, the temperature displayed is directly transmitted.

You can change this temperature in 0.5°C steps by pressing any

other key.

The temperature can be adjusted between OFF, 20°C and 60°C,

although if a temperature limit is set in the appliance, this remains

effective.

Holding down "+" or "-" changes the temperature display in 0.5°C

steps until the key is released again.

When the key is released, the required temperature is transmitted.

The required temperature is transmitted approx. 0.5seconds after

the last key is pressed. The progress bar on the display indicates

that data is being transmitted.

f To shut down the heating system, set a temperature of 20°C.

Then press "-" again.

OPERATION

Appliance description

Saving temperature to memory keys

f Set the required temperature using the "+" and "-" keys on

the wireless remote control.

f Press memory key "1" or "2" for 2seconds. The temperature

display ﬂashes once to conﬁrm. You can assign the memory

keys individually for each wireless remote control/ program-

ming unit.

Note

When activating the anti-scalding protection in the in-

stantaneous water heater, you can only set the DHW tem-

perature to the set anti-scalding protection temperature.

Higher temperature settings are not implemented.

3.2 Dynamic anti-scalding protection

Dynamic anti-scalding protection automatically assigns prior-

ity for setting the maximum temperature to the ﬁrst wireless

remote control or programming unit at which a temperature is

set. This priority is available for 2minutes or until 2minutes

after the end of the current draw-off. After this, the priority is

automatically disabled.

Whilst the priority is enabled, the temperature can be reduced

or increased to a maximum of 43°C by other programming

units.

CAUTION Burns

For operation with a shower, please observe the infor-

mation in the instantaneous water heater description

(chapter "Installation/ Safety/ Shower operation").

3.3 Changing the battery

!Material losses

f Remove the old battery.

Any damage caused by a leaking battery is excluded from

the warranty.

ti-scalding protection.

“Con” occasionally ap-

pears on the display.

The wireless remote con-

trol is outside its range.

Reduce the distance

between the wireless

remote control and the

appliance. Resend the

temperature request.

“Con” frequently appears

on the display.

The battery is at the end

of its capacity.

Change the battery (see

chapter "Appliance de-

scription/ Changing the

battery").

If you cannot remedy the fault, notify your qualiﬁed contractor.

To facilitate and speed up your request, provide the number from

the type plate (000000-0000).
