Wireless small actuator operating modes
!NOTICE
All operating modes including self-controlled mode and frost protection function become available
after startup, i.e. after successful teach-in on a radio partner
Actuator mode
If a 0 to 100% EnOcean telegram is received from an external radio partner for controlling the radio
small actuator, the internal loop controller is not active.
The transmitted actuating signal is translated into a positioning movement.
A suitable radio single room controller takes over the control functions.
Self-controlling operation
The integrated room temperature controller is activated if no external 0 to 100%
EnOcean radio telegram is received.
- Without external operator panel (= emergency mode):
The temperature is controlled to a fixed setpoint of 20 °C using the integrated temperature sensor
(actual value) and the integrated control function of the actuator.
- With external operator panel (EnOcean technology):
Using the operator panel, the users can freely determine the setpoint or enter their own schedule.
The actual value and the setpoint are transmitted via an EnOcean telegram (EEP A5-20-01).
The integrated control algorithm makes room control easy and convenient.
Battery monitoring
The battery capacity is continuously monitored. If the battery capacity is too low, a radio signal is
transmitted to the radio partner and 2 acoustic signal tones are emitted in succession every 6 hours.
If this message is activated, the remaining capacity of the batteries is < 10%.
!NOTICE
The batteries must be replaced within the next 30 days.
As the battery level decreases, the interval between the audible signals becomes shorter and the
number of signal tones increases to 4 signal tones in succession every 3 hours.
If the remaining battery capacity is insufficient to maintain motorized operation, the actuator moves
into the safety position of 50%.
The radio communication with the radio partner still functions in this operating state.

Product DescriptionMD15-FTL-HE, MD15-FTL-OV
Datasheet 3.09-20.315-01-EN Issue 2017-01-09 Rev 1
Valve recognition
During commissioning, the actuator detects the closing point and the total stroke of the valve.
After the batteries are changed or after the unit is successfully taught in on a radio partner, this
detection process is performed again via the Init.
Valve block protection
Block protection prevents the cone from jamming when the valve is inactive for a long time. When
block protection is active, the actuator performs a displacement of 50% once every 21 days.
If the remaining battery level is < 10% (see “Battery monitoring” section), this function is inactive.
This function can be switched on and off (see p. 20).
Automatic closing point control
The small actuator continuously monitors the closing point and corrects it if necessary.
Communication test
The radio communication path to the radio partner is checked.
Performing a communication test has no effect on the transmission/reception interval (see p. 20).
Energy block (automatic “Window open” recognition)
When a window is open, the flow of heat energy to the room is interrupted. An open window is
signified by a large and rapid temperature drop at the MD15-FTL-xx small actuator. If such a drop is
measured by the internal temperature sensor, the small actuator closes the valve for 30 min.
After 30 minutes, the small actuator returns to normal operation and the automatic “Window open”
recognition function is active again.
If the remaining battery level is < 10% (see “Battery monitoring” section), this function is inactive.
This function can be switched on and off (see p. 21).
Frost protection function
If the temperature at the integrated temperature sensor drops below 6 °C, the small actuator opens
the valve until 8 °C is reached.
Summer mode
If the status message “Summer mode on” is received from an external radio partner, the small
actuator closes the valve.
The transmission/reception interval in summer mode is permanently set to 60 minutes.

Radio Interface
The communication with the radio partner is cyclical, bidirectional and includes intelligent reception/
transmission management.
Upon the first reception of the radio telegram (for teaching-in a radio partner, see page 19), the radio
small actuator automatically adapts its operating mode according to the method of control from the
radio partner (actuator mode or self-controlled mode).
NOTE
If the communication with the radio partner is disrupted, the “emergency mode” status bit
(self-controlled mode) is set (can be evaluated for service diagnostics).
After the malfunction has been rectified (details can be found in the documentation of the radio
partner), the radio partner is automatically resynchronized.
!NOTICE
This product uses only EnOcean telegrams
When selecting a radio partner, ensure that the radio interface also works with the EnOcean telegram
EEP A5-20-01 (Battery Powered Actuator).

Mounting the Valve
!NOTICE
The valve may only be installed by qualified technicians. In addition to the generally valid installation
guidelines, the following points are to be observed:
■The pipeline system and the interior of the fitting must be free of foreign objects. In the event of
contaminated media, dirt collectors are to be inserted upstream of the valves with fine screens,
mesh width 0.25 mm.
■There must be no tension between the valve and the pipeline connection.
■To avoid eddy formations in the valve body, the valve should be installed in a straight section of the
pipe. A distance of 10 times the nominal diameter is recommended between the valve flange and
manifold or other similar parts.
■The installation location is to be selected so that the ambient temperature at the actuator is kept
between 0 – +50 °C.
■When carrying out installation, the permissible maximum pressure difference p and the specified
direction of flow must be observed (see table in "Types" section).
■Once the valve is installed, make sure the ball in the valve seating can be moved easily by pushing
in the valve stem.
■Approximately 30 mm of free space is required above the actuator to install the actuator and
remove the housing cover.
■For safety reasons, do not suspend the small actuators from under the valve.
■Observe the direction of flow arrow on the valve body. Inverting the direction of flow impairs control
behavior.
