Item 8, Failsafe Operation and Display When Wireless
Connection Is Interrupted. The range of the wireless
connection is largely dependent upon the room conditions
and the battery charge level of the wireless room
temperature sensors. Reinforced walls and ceilings and
metal casings reduce the effective communications range.
This device does not require maintenance.
Depending on the device type or packaging size, the device
is delivered either in a closed state or already opened for
faster mounting. After being mounted, the wireless heating
control should be connected according to the connection
diagram (Item 10).
4. Initial Operation
When you turn on the power, the wireless heating control
(receiver) is immediately ready for use and the wireless
room temperature sensors (transmitters) belonging to it can
be registered (Item 4.1). After assigning the wireless room
temperature sensors to the wireless heating control, ensure
that heating is functioning using the actual transmission
path. To do so, set the target value of the wireless room
temperature sensor to the maximum value. Heating must
activate within three minutes. Caution: Due to the control
range, this check can only be performed when the room
temperature is below 28–29 °C.
4.1 Registration function (establishing the
wireless connection)
The registration function is used to assign a wireless room
temperature sensor (transmitter) to the corresponding
wireless heating control (receiver).
Before registration:
A wireless room temperature sensor can be registered with
a wireless heating control in the following three scenarios:
1.) A wireless room temperature sensor has not yet been
registered with the wireless heating control. In this case, the
light on the wireless heating control is continuously red.
2.) One or more wireless room temperature sensors were
registered with the wireless heating control within the past
hour. In this case, the light on the wireless heating control is
green, indicating a working wireless connection to the
sensors.
3.) One or more wireless room temperature sensors were
registered with the wireless heating control more than one
hour ago. In this case, the light on the wireless heating
control is off, indicating a working wireless connection to the
sensors.
Registration procedure:
Note: To activate the registration mode on the wireless
room
temperature
sensors,
follow
/installation instructions. There is usually a register button
on the sensor. However, wireless room temperature
sensors with a display may also have a button combination
with indication on the display.
1.) Briefly press the register button on the wireless heating
control. The light on the wireless heating control flashes
red for a maximum of 30 seconds. If no wireless room
temperature sensor is registered during this time, the light
stops flashing and returns to its initial state.
2.) Activate the registration procedure on the wireless room
temperature sensor. The light on the wireless heating
control switches from flashing red to green, and the wireless
connection is established.

registered sensor is valid.
** Only one wireless room temperature sensor with a clock
can be registered. When you register a second wireless
room temperature sensor with a clock, the previous one is
deleted. The last registered sensor is valid.
4.3 Installation mode indication
The temporary installation mode indication on the wireless
heating control helps you to more quickly check the wireless
connection under the actual conditions of use during
installation. Installation mode begins when a wireless room
temperature sensor has been successfully registered and
lasts approximately one hour. During this process,
installation mode is indicated by a continuous green light.
When you register more than one wireless room
temperature sensor, the time starts over after the last
registration procedure. To reduce installation time, any loss
of connection during this time will be indicated after two
minutes. For other displays on the wireless heating control,
see Item 5, Indicator Lights. After placing the wireless room
temperature sensor in the room you want to regulate, you
should again check for the continuous green light on the
wireless heating control to ensure that the wireless
connection is working. If the wireless connection has been
interrupted, the light will turn red after two minutes. One hour
after registration, the green light goes out, indicating normal
operation.
4.4 Wireless connection function and assignment
check
You can use this function to check whether wireless room
temperature sensors (transmitters) are correctly assigned to
various wireless heating controls (receivers). This makes it
easy to find mistakes later on.
Start the registration procedure on the wireless room
temperature sensor during this time, the light on the
wireless room temperature sensor flashes red. If the light on
the wireless heating control starts to flash green, the sensor
is registered with it and the wireless connection is
established. Caution: For wireless room temperature
sensors with a register button, only press the button briefly.
If you press the register button on the wireless room
temperature sensor longer than ten seconds, the device
switches to deregistration mode (see Item 7.1).

6. Master-slave control (automatic operation for
multiple rooms via central wireless room temperature
sensor with a clock)
6.1. Explanation of terms
Master (main control or pilot control) – is a higher-level
control with a higher priority than the slave control, which
influences the temperature control of the room in which it is
installed and is also responsible for energy-saving times and
special functions in all rooms where it has been registered.
Slave (follow-up control or satellite control) – is a lower-
level control with less priority than the master control, which
only influences the temperature control of the room in which
it is installed.
Energy-saving times – are time periods when heating is
adjusted to a lower room temperature or cooling is adjusted
to a higher room temperature in order to save energy.
Energy-saving times are usually during the periodic

be entered as a clock program in the master.
ECO temperature – ECO (also ECON) comes from the
word "economy" and refers to saving. With regard to room
1*
temperature control, energy is saved during the absence of
persons or during rest periods by adjusting the temperature
to a value which allows the consumers to be switched on
less often instead of to the comfort temperature.

Special functions – are functions that are activated by the
master device. These functions include holiday function,
party function, on/off function, self-learning function, and
valve and pump protection. These functions are described
in the operating/installation instructions of the master.
Wireless heating control (also called "receiver"
colloquially) – is a heating control that receives target and

actual temperature values and other special functions
wirelessly and adjusts the heating for the room accordingly.
Wireless
room
temperature
sensor
"transmitter" colloquially) – is a temperature sensor that
measures the room temperature and transmits this value to
the wireless heating control wirelessly. Wireless room
temperature sensors are usually equipped with target value
regulators to set the desired temperature. An exception is a
wireless room temperature sensor that is used for
calculating the average room temperature when the room
heats unevenly. Wireless room temperature sensors with
clocks use a time-controlled energy-saving function for
individual-room temperature control and can be used as a
master.
6.2 Installation of master-slave control
The master-slave control is an extension of an existing
individual-room temperature control. For individual-room
temperature control, a wireless room temperature sensor
with a target value regulator (transmitter) is registered with
each wireless heating control (receiver) of a room. To
establish a master-slave control, an additional wireless
room temperature sensor with a clock is registered with the
wireless heating controls of the individual rooms. During
installation, you do not have to pay attention to the
sequence in which the different wireless room temperature
sensors are registered, but note Item 4.2. No other wireless
room temperature sensor is installed in the room where the
master is. For the master-slave control, you should pay
special attention to the range of the wireless connection,
since installation requires greater transmission paths to be
bridged. Therefore, after installation you should check the
wireless connection over the entire transmission path (see
Item 4.3).
Wireless room temperature sensor function type 003 has a
switch that you can use to switch between comfort and
energy-saving operation modes. Within a master-slave
installation, the ECO function of the switch switches
automatically to "participation in master-slave operation". In
the comfort operation switch setting, the room will not
participate in master-slave operation, and the temperature
is permanently set to the target value of the room sensor.
6.3 Master-slave functions
For these functions, also follow the operating/installation
instructions for the master being used.
Energy-saving function – The energy-saving times
entered in the master apply to all rooms in which the master-
slave control is installed. During comfort heating times, the
temperatures set on the individual slaves apply. During
energy-saving times, the ECO temperature of the master
applies, but only if the master's ECO temperature is lower
than the slave's comfort temperature. The energy-saving
function is activated for all rooms with slaves when the
master is set to the ECO operation mode.
Holiday function – The holiday time entered in the master
applies to all rooms in which the master-slave control is
installed. During holiday time, the holiday temperature of the
master applies, but only if the master's holiday temperature
is lower than the slave's comfort temperature.
Party function – The party time entered in the master
applies to all rooms in which the master-slave control is
installed. Until the end of the party time, the temperature in
all rooms is adjusted according to the comfort temperature
values of the individual slaves.
On/off function – The on/off function on the master applies
to all rooms in which the master-slave control is installed.
Caution: This function does not provide frost, valve or pump
protection. If these functions are to be provided without
switching on the heating when undesired, set the operation
mode on the master to "ECO energy-saving operation" and
set an appropriate desired ECO temperature for the frost
protection. You can also set the target temperature in all
rooms to the minimum.
Self-learning function – If the self-learning function in the
adjustment menu of the master is activated, it applies to all
rooms in which the master-slave control is installed. It is
assumed that the times required to heat up the individual
rooms are not that different.
7. Deregistration of All Wireless Room Temperature
Sensors from the Wireless Heating Control (Deletion of
Entire Reception Channel)
This
function
is
required
to
transmitters from the memory of the wireless heating
control.
Press and hold the register button on the wireless room
temperature control until the light turns continuous red after
approximately 10 seconds. The successful deletion of the
entire reception channel is indicated by a continuous red
light for the deleted channel, and the control is deactivated.
After the deletion procedure, the wireless heating control is
(also
called
delete
non-functional
