2.4 Functions
• Actuating distance and limit position scanner
The calculation of the available lifting stroke is based on the detection of the
two limit positions by the SmartDrive MX patented actuating distance scanner.
The corresponding valve position can be transmitted via the associated
EnOcean protocol to a master controller/gateway.
• Battery warning
The moment the battery drops below a critical voltage the SmartDrive MX will
transmit an error code to a master controller. Furthermore, the battery symbol
will appear on the display screen. From that moment onwards you have 30
days left before the batteries need changing.
The symbol for “adapted“ will disappear. You have to readapt the SmartDrive
MX after a battery replacement by pressing the key (See 5.1)
• Emergency actuating function
The SmartDrive MX opens the valve 100% as soon as the battery voltage
drops below a critical value.
• Internal PI controller
The moment the SmartDrive MX loses continuous radio contact (three times
wake-up without reception) to its taught controller / gateway the internal PI
controller will take over and will adjust the temperature according to the set
temperature value. A parallel option is local adjustability of target temperature
by operating the dial.
Additionally, the display screen shows the symbol -><-. A message sent by
the controller may appear on the smartphone/PC. Simultaneously the
SmartDrive MX uses the reclaim telegrams to check the availability of the
controller at every wake-up. The centre will reassume control as soon as
connection has been re-established.
• Radio interface
The SmartDrive MX comprises an EnOcean radio interface based on 868.3
MHz, as per ISO/IEC 14543-3-10 featuring extremely low energy
consumption. The EEP belonging to the SmartDrive MX is A5-20-04.
• Manual setting of target temperature manually
The manual setting option for target temperature is available via the dial at all
times. As soon as the dial is turned the SmartDrive MX will wake up and show
the set target value on the display. This temperature is shown for a range of
10°C to 30°C in 0.5°C steps.
• Room and supply temperature detection
Supply and room temperature are both detected by an integrated temperature
sensor. A specially developed correction algorithm clears the measured
values of other temperature influences. Thus, actual temperature values are
determined and forwarded for further processing.
• Frost protection
The lowest adjustable target temperature is 10°C. As soon as the actuator has
been taught and connection to the controller has been established, the room
temperature will not drop below 10°C. If the actuator detects via the internal
sensor that the room temperature has dropped below a value of 10°C, the
controller will receive additional communication. (error telegram 0x14 -> !20).
If radio connection is interrupted permanently, the internal PI controller will
take over on reaching the temperature threshold of 10°C and control the room
temperature in such a way that it reaches 10°C.
A precondition for this control is, however, that sufficient heating performance
is in place.

SmartDrive MX
8Version 1.1 - May 2014 Installation and operating instructions
• Valve blocking protection
The blocking protection prevents a locking of the cone during longer valve
shut down. Variable definitions of cycle as well as route are available with the
help of the controller.
• Micro USB interface
The micro USB interface can be used for providing the SmartDrive MX with
energy.
• Keyboard lock
It is possible for the SmartDrive MX to receive a command for key locking via
the controller. In that case, you will no longer be able to set the target
temperature for the SmartDrive MX manually. If key lock is enabled during the
emptying of the batteries, it will be disabled for the new adapting process. If
the SmartDrive MX will loose the connection to the controller, the input lock
will be disabled to allow a manual temperature control.
• Transmitting cycle
The SmartDrive MX spends the greater part of its operating time in deep sleep
mode so as to keep energy consumption as low as possible. You can select
the periods for deep sleep mode by using a radio telegram from a selection of
63 time cycles. The predefined times for the deep sleep mode range from 10s
to 42h. If the index of this field variable is set to 50 or above, the actuator will
interpret this as a command for changing to so-called summer mode.
• Summer mode
Summer mode is characterized by deep sleep mode that from now on will last
at least 3h. The moment this mode is enabled, the valve will open completely,
thus conserving the valve seal among other things. You can exit summer
mode by reducing the cycle period for the deep sleep mode to an index that is
smaller than 50. Afterwards, you must re-adapt the actuator to the valve so as
to re-establish reliable operation.
• Error messages
Various errors may occur during normal operation or commissioning. Error
messages are displayed on the display screen and communicated to the
controller by radio.
For possible error messages, see checklist.

2.5 Data Transfer
The SmartDrive MX comprises a bidirectional EnOcean interface. This allows
data transmission in either direction between the SmartDrive MX and the centre.
The following data can be sent by SmartDrive MX :
•Current valve position
The current valve position is transmitted as a percentage value ranging from
0% to 100%.
•Supply temperature
The current supply temperature is transmitted, ranging from 20 °C to 80 °C.
•Target temperature
The target temperature set manually at the SmartDrive MX is transmitted,
ranging from 10 °C to 30 °C.
•Room temperature
The current room temperature is transmitted, ranging from 10 °C to 30 °.
•Error codes
The SmartDrive MX can send error messages to a remote computer.
8 Trouble shooting on page 15
•Teaching telegram
Additionally, there is the option of sending a teaching telegram (according to
EnOcean Smart Acknowledge-Standard) in order to connect the SmartDrive
MX to a controller.
The following data can be received by the SmartDrive MX:
•Target valve position
The target valve position is transmitted as percentage value, ranging from 0%
to 100%.
•Target temperature
The target temperature, ranging from 10 °C to 30 °C can be transmitted by a
centre to the SmartDrive MX .
•Transmitting cycle
The transmission cycle can be adjusted with the help of a command. Possible
time values have been defined for that purpose.
•Adaptation
You can introduce a new adaptation process with the help of a command.
•Assembly status
To facilitate assembly or disassembly you can use a command that makes the
thermostat tappet retract completely.
•Input lock
You can use a telegram from a centre that disables or enables local entries by
dial or control key.
•Temperature Measurement
Temperature monitoring can be disabled by telegram. ( if using a separate,
external temperature senor)
•Summer / winter function
Switching between summer and winter function
