its, attached on the back). The Mac address serves as a username and
password.
Aer successful login, you have to assign individual access data.
As soon as you have assigned this data, all heating programs and oth-
er parameters can be set easily and conveniently via the app.
Important notice:
In order to guarantee the smooth functionality of all thermostats and devices as a unit, all components (including the devices that will be
added later) must be registered via the gateway as described on page 5 (“Registration of the radiator thermostat”).
Automatic recognition of the IP address and automatic
speech recognition. It is not necessary to set the winter and
summer time or the date and time.

Settings via the thermostat
With a wake-up time (e.g. 7:00 a.m.), the heating phase begins at 7 a.m. The thermostat automatically switches to comfort mode. (The settings
on the thermostat are optional. All settings for the heating programs and temperatures can be made easily and conveniently with the app)
Please note: The Hera+ thermostats only control the individual rooms (temperature and times). Please note the times at which the boiler is set.
With the Comfort program you control your comfort temperature
(factory set to 22 °). The desired temperature and program times can
be conveniently set using the thermostat and the app. If the Sensor
is activated and no people are present within 30 minutes, the system
lowers the temperature by 2 ° and switches to eco mode or night re-
duction aer another 30 minutes (depending on the time of day). If
the Sensor detects a movement, the program immediately switch-
es to comfort mode. If the Sensor is deactivated (only possible via
the app), the temperature remains constant until the next switching
phase (eco or night reduction). You can also find detailed instructions
in the app description.
Comfort heating program
With the Eco program you can set the desired temperature for longer
periods of absence (set to 12° in the factory). The desired tempera-
ture and program times can be conveniently set using the thermo-
stat and the app. By pressing the Eco button on the thermostat, you
can switch directly from Comfort mode to Eco mode. To do this, the
motion Sensor is deactivated for 10 minutes. If the Sensor detects
movement aer 10 minutes, the program switches back to Comfort
mode. If the Sensor is deactivated (only possible via the app), the
temperature remains constant until the next switching phase (Com-
fort or night setback). Detailed instructions can also be found in the
app description.
Eco heating program
Explanation of the heating programs
This program lowers the temperature at night to save energy (set to
16° at the factory). You can easily set the desired temperature and
program time using the thermostat and the app. The motion Sensor
is deactivated during the night setback. By pressing the night set-
back button on the thermostat, you can switch directly from Comfort
mode to night setback. When the Sensor is deactivated (only pos-
sible via the app), the temperature remains constant until the next
switching phase (Eco or Comfort). Detailed instructions can also be
found in the app description.
Night Setback heating program
By pressing the night setback button on the thermostat twice, you
can set the time at which morning comfort is to be activated. Set the
desired time and confirm the setting by pressing the night setback
button again. All settings of the heating programs and temperatures
can be made easily and conveniently with the app. Detailed instruc-
tions can also be found in the app description.
Heating time setting
In the first heat-up phases aer commissioning, the valves are auto-
matically adjusted and set by the Hera+ system. This process is re-
peated several times as required. This process allows the system to
adapt to the individual conditions in the premises.
Adjustment phase Hera+ System
Reset thermostat to factory setting
Switch o the thermostat -> Press the up arrow key until SET and a number appears -> Select „0“ with the arrow keys -> Confirm with the
comfort key -> Switch the thermostat on again („REG“ appears in the display), it must then be registered again.

Declaration of conformity
Note:
When the batteries are empty and the ther-
mostat switches o, the heating continues
to operate in the last activated mode. Frost
protection (6 ° C) is activated to prevent the
heating from freezing and the rooms from
cooling down unintentionally.
What is to be done?
To restore normal operation, please change
the batteries immediately. The system has
a memory function that automatically re-
stores the heating program that was set last.
The devices are not suitable for children and must not be used as toys. Store and dispose of packaging materials in a child-resistant manner.
Do not disassemble the devices, as they do not contain any user-serviceable parts. If the error code E1, E2 etc. is shown on the display or other
defects occur, please return the thermostat to the dealer.
These appliances may be used by children over 8 years of age and by persons with reduced physical, Sensory or mental abilities or lack of
experience and knowledge, provided that they have been supervised or instructed in the safe use of the appliances and understand the risks
involved. Children must not play with the equipment. Cleaning and user maintenance must not be performed by children without supervision
Warning notice
The Hera+ Primus PRO Tres Set is suitable exclusively for controlling underfloor heating systems. The regulation of e.g. cooling circuits, radia-
tors is not permitted and can lead to damage.
Intended use
Valve protection function:
The system opens and closes the valves au-
tomatically once a week, thus ensuring that
the valves do not get stuck or block.
Reset radio underfloor heating bar to factory settings
Press the reset button on the radio underfloor heating bar for 30 seconds -> LED diode starts to flash -> The bar must be registered again with
the gateway and therefore the connected thermostats with the bar.
