The set temperature will remain until the set end time. After-
wards the EVN SmartHome wall thermostat will switch to Auto
mode. Radio control commands like those from a window
contact or the weekly de-scaling run will still be performed.
17.7 Setting valve protection function (dEC)
To prevent the build-up of lime scale in the valve a so called
“de-scaling run” will be performed weekly for the radiator
thermostats. You can change the set time for this function
(factory setting: Saturday, 12:00 p.m.) as follows:
• Press the Menu button for more than 3 seconds.
• Select the “dEC” menu item with the (
+

While the “de-scaling run” is performed the display will
show “CAL”.
17.8 Open window function / airing (
, AEr)
During the airing of a room the EVN SmartHome Wall Ther-
will automatically reduce the room temperature to
save heating costs. Meanwhile, in this phase the display of
the EVN SmartHome Wall The and all taught-in
devices will show the open window symbol (
).
Combined with a EVN SmartHome Window Sensor the
opening and closing of a window will be detected time-ac-
curate. The temperature will only be reduced to the facto-
ry setting of 12° C while the window is opened. Once the
EVN SmartHome Window Sensor registers the closing of
the window, all components installed in the room will be
reset to the previous mode.
To change the reduced temperature setting proceed as
follows:
• Press the Mode button for more than 3 seconds.
• Select the “AEr” menu item with the (
+
) and (
-

• Confirm the setting with the OK button.
• Set the temperature with the (
+
) and (
-
) buttons.
• Confirm the setting with the OK button.
17.9 Setting the offset temperature (tOF)
As the temperature is measured on the room control unit the
temperature distribution can vary throughout a room. To
adjust this, a temperature offset of ±3.5°C can be set. If a
nominal temperature of e.g. 20°C is set at the room con-
trol unit but the room presents with only 18°C an offset of
-2.0°C needs to be set.
• Press the Menu button for more than 3 seconds.
• Select the “tOF” menu item with the (
+
) and (
-
) buttons.
• Confirm the setting with the OK button.
• Set the offset temperature with the (
+
) and (
-
) buttons.
• Confirm the setting with the OK button.
18. Teach-out / Reset (rES)
The initial state of the EVN SmartHome Wall The
can be restored manually, e.g. to teach-in a single room
solution to a EVN SmartHome Cube or to re-install an in-
correctly operating system. Restoring the initial state de-
letes all settings and information about taught-in devices.
