Intended use
The radio thermostat may only be used to meas-
ure the ambient temperature and to operate
Easywave radio receivers.
The manufacturer shall not be liable for any dam-
age caused by improper or non-intended use!
Safety instructions
Please read the operating instructions
carefully before using the device!
- Also read the operating instructions for the
devices to be controlled! Do not modify the
devices!

Function
The temperature sensor ST01 is a battery-operat-
ed radio thermostat for indoor use. Detected de-
viations from the setpoint are send via Easywave
radiogram to radio receivers which are connected
to a heating system. That way, the temperature
can be controlled between approx. 14 °C and
approx. 25 °C via radiogram.
The ST01 can be operated in the control mode
ON/OFF or PWM optionally. These control modes
determine the intervals in which radiograms will
be sent:
Format 55
ON/OFF (I/O): If the measured temperature is
above the set target value, the heating is switched
off. If the actual value is below the target value,
the heating is switched on.
The ST01 sends a status telegram with the cur-
rent switching state every 4 hours in order to
not trigger the emergency switching of the cor-
responding receivers (e.g. RCJ15 and RCP22).
This also happens when the ST01 is turned off
(OFF).
PWM (Pulse width modulation, only with com-
patible receivers possible): PWM is an adaptive
control mode. The temperature sensor analyzes
the heating behaviour and sends switching com-
mands in larger time intervals. This extends the
battery life.
You can select three different operating modes
on the temperature sensor: day operation, night
setback and anti-freeze. You can also turn off the
temperature sensor entirely.
In the operating mode day opera-
tion, you can save room temperature
setpoints for the desired day room
temperature permanently.
In the operating mode night setback,
you can save room temperature
setpoints for the desired night room
temperature permanently.
In anti-freeze mode, the temperature
remains constantly around the freez-
ing point in order to prevent pipes
from freezing.
OFF No temperature control at OFF.
The status code B (OFF) is transmit-
ted every 4 hours.
The temperature sensor is delivered with the
following settings:
- Control mode I/O
- Operating mode day operation
- Setpoint room temperature 20 °C.
Start-Up
1. Insert the batteries
Insert the included batteries into the trans-
mitter module.
Make sure the polarity is correct! The
positive pole has to be visible
2. Program ST01 into the receiver and
select temperature
1. Put the receiver into programming mode.
Please read the operating instructions
supplied with the receivers.
2. Press the button or
the sensor to send a telegram.
The Easywave Code A (+) or B (-) will
be sent. For this operation the sensor
must be in the operating mode. All LEDs
must be off.
→ the radio symbol
lights up briefly (2 s) and the transmit-
ter has been programmed into the
receiver
3. Press the
set the temperature setpoint.
4. Do not press any button for 10 seconds.
The sensor switches to operating mode,
the set target value is saved and the
LEDs are off.
3. Mount the sensor
1. Screw or stick the mounting plate (D) to
the installation site.
2. Put the cover frame (C) on the mounting
plate (D).
3. Lock the transmission module (B) on the
catches (E) and mount the cover (A).
Displaying/setting the operat. mode
1. Press the
operating modes
→ the LED in the right column (F) displays
the operating mode of the sensor
→ the LED in the left column (T) displays the
current temperature and the temperature
setpoint
2. Do not press a button for 10 seconds to save
the settings, the LED goes off.
