4 System description

This document defines the properties of Micropelt’s battery free, intelligent thermostatic radiator valve (iTRV).
MVA005 is an 868MHz EnOcean wireless actuator, which is self-powered through thermal energy harvesting.
It is used to single room control heating radiators with standard valve connection M30x1.5 (Section 13). To
operate the device, the unit must be paired with a compatible room controller or gateway unit supporting EEP
A5-20-06. The pairing is done either via manual 4BS Teach-In or trough EnOcean Remote Commissioning.
Once mounted and activated on the valve body, a calibration cycle starts to automatically adapt itself to the
individual valve and is ready for use. Adapter are available for a majority of non M30x1.5 valve bodies (Section

14).

Room controller time schedules can be conveniently used to set individual room temperatures at different
times and to a desired °C value. By lowering room temperatures in times of absence, heating costs can be
saved without any loss of comfort. Reducing the room temperature by only a few °C does further add to
reduction of heating energy consumption and respective CO2 pollution.

The actuator generates the required electrical energy for operation (motor, sensors and radio communication)
by means of a built-in thermoelectric generator (TEG) and therefore operates maintenance-free. It is powered
from the temperature difference between the radiator heat and ambient temperature (usually room
temperature). An additional energy source such as a battery or external power supply is not required. The
internal energy storage is fully charged upon delivery, so that sufficient energy is available for installation and
up to approximately one year of operation. In winter and heating season, the actuator then supplies itself
independently trough the converted heat of the heating circuit. Due to the surplus of generated energy in
winter, the internal storage provides sufficient energy for 365 days per year operation including transition
periods and summer.

The product is delivered in mounting position (off) with the valve plunger completely retracted. The drive does
recognize when installed on a valve body by means of internal force and travel distance measurement.
Unmounted activation does allow to execute Remote Commissioning operation (Instant SIGNAL telegram is
transmitted immediately after each activation from mounting position) but will always return the device back to
mounting position to switch off. The drive does have a built-in motor error detection "ACO". The ACO bit does
signal incomplete or unsuccessful reference runs from mounting, motor issues during normal operation as well
as motor runs from mounting position and back to mounting position (Section 8.2.6).

The actuator operates with the EnOcean equipment profiles EEP A5-20-06 in either valve position (% value
transmitted) or temperature setpoint using its internal temperature control loop (°C setpoint transmitted). The
device has a built-in flow temperature sensor to automatically switch its Radio communication cycle (2, 5 or
10 minutes) based on available radiator temperatures. Installation and activation will immediately set the radio
communication interval to every 2 minutes and for an installation period of 30 minutes to provide quicker
feedback (Section 8.2.9). The ambient temperature value transmitted during such installation period is the raw
and actual temperature (Without approximation and smoothing). The device transmits a variety of information
to the room control unit including flow and ambient temperature, received radio signal strength, radio
communication failure, window open detection (Refer to Section 8). The control units responds either with a
new position value in the range 0% (valve closed) to 100% (valve open) or temperature setpoint (0 ... 40°C).
Setpoint changes will be instantly processed and new position values are calculated.

The MVA005 has a red and a green LED to support and indicate successful or failed operations for activation
and deactivation (More details in Section 6).

The device is equipped with a dial for local user setpoint changes that are instantly transmitted to the room
controller. The controller however decides whether or not and how these local changes are accepted and
processed by responding with a corresponding telegram answer that includes or ignores the local change
request. In valve position mode, all local changes are transmitted as relative values. Changes in temperature
setpoint mode are added or subtracted to the current set point temperature and transmitted as absolute
temperature value on the controller (Section 8). Successful local inputs are confirmed by a corresponding
number of discreet ton signals. Successive inputs within a maximum time period of 5 seconds time are
transmitted as a result value to the room controller. Example: 2 x right (+ 2°C) followed by 2 tone signals.
Within the 5 seconds period 3 x left (-3°C) followed by 3 tones. The result of -1°C is transferred after 5 seconds

MAR 2019 Page 4 / 33 MVA005_1DS_0319v2e.docx

MVA005
User manual and Datasheet

on the room control unit. There will be no further tone signal to confirm the result of -1°C. Incorrect inputs will
be displayed by an approx. 2 seconds long red LED signal. Failed attempts will require a waiting period of 2
seconds. Local changes will lead to an instant telegram transmission to the room controller. In case of no
response from the correspondent room controller, another telegram will be transmitted 1 second later.

Integrated temperature sensors (valve body and environment) are both used to control the radio interval and
internal temperature controller, window-detection as well as freeze protection. The ambient sensor is used to
measure the room temperature. During heating operation, the ambient sensor is influenced by the near-field
of the radiator as well as self-heating of the metallic device housing. The resulting temperature failure due to
offset is compensated on the basis of the flow sensor and a built-in temperature compensation
(approximation), as well as a subsequent smoothing function. Within the first 30 minutes after activation, the
actuator sends the actual ambient temperature without any corrections. After 30 minutes, the device sets the
ambient temperature to its smoothing start value to 20°C that will be kept as long as the calibration cycle takes.
The approximation process in a non-heating cycle takes 3 x 10 minutes. Device activation in an active heating
cycle will extend the start value and smoothing cycle to as long as the measured ambient and flow sensor
values stabilize with deviations smaller than 1°C. When operated in temperature setpoint, the use of an
external room temperature sensor is recommended which is then transmitted to the MVA005 with every 4BS
telegram through the room controller. Without external room sensor, the built-in ambient sensor is used with
the respective in accuracy given the nearfield radiator environment or any other related effects such as
mounting position, curtains, furniture. (See picture 4.1).

Anti-freeze protection uses the flow sensor integrated in the metallic valve connection. Standard freeze
protection is active at <6°C. With a temperature setpoint transmission of 0°C, than the freeze protection
temperature is also lowered to 0°C. It does not matter if the 0°C setpoint value was requested by radio or by
manual adjustment.

Alternate flashing of red and green LEDs in 0.5 second intervals signals a sensor error (short circuit or
interruption). In this condition, normal operation is not possible.

Window open detects any temperature drop within a time period of 2 minutes on the local ambient temperature
sensor. Once a given negative temperature change is detected, the device sets the DWO bit (Section 8.2.7)
and immediately reports the state transmitting a 4BS telegram to the room controller. Its transmitted ambient
temperature is the actual temperature value (no approximation or smoothing). The window open detection
function is limited to the transmission of data telegrams and setting the DWO bit, no further internal reactions
by the actuator apply. The detection of a temperature drop depends on a recognizable stream of cold air in
the close environment of the actuator. For a reliable detection, the drive must be installed in unspoilt situation
and on radiators below the respective window. Fully opened windows in winter season are usually reliably
detected at low outside ambient temperatures. Window in tilt position and heaters in faraway distance to the
window cannot be detected reliable. The window open function is independent of the selected communication
interval and automatically runs every 2 minutes. Should the temperature fall further and below freeze protection
temperature of 6°C (respectively 0°C), the drive automatically opens to prevent from freeze related damages.

Radio failures after 6 unsuccessful 4BS communication attempts in paired situation are reported with its status
bit RCE. The actuator automatically switches to its internal temperature control using the last received and
valid temperature setpoint from the control unit. With the lack of a valid temperature setpoint °C value (e.g.
SPS=0 operation), the internal default value of 21°C is used. Radio signal strength of the received telegram
(RSS) is also activated due to lack of incoming data telegrams. There is no change on the radio communication
cycle. The local offset function of the dial remains active and any local adjustments are calculated from a
default value 21°C. E.g. 5 x left decreases the setpoint from 21°C to 16°C, independent from the last received
setpoint value. Due to lack of response from the master control unit keeps the drive this setpoint and regulates
accordingly. Consecutive local changes are again calculated from the default value of 21°C, e.g. 3 x right =
24°C followed by 1x right = 22°C. The drive returns to normal operation, once the radio communication is re­established.

When permanently use in unheated rooms, the internal storage will be ultimately discharged. In such
circumstance, the drive automatically opens to 50% for recharging. For operation in unheated rooms, the valve
and its EEP A5-20-06 provide options to reduce and minimize energy consumption through either stand-by
operation (SBY Bit) or summer bit (SB) 8 hours radio interval. Using the local offset input, the drive can at any
time be activated from standby (SBY) and returns to normal operation.

MVA005
User manual and Datasheet

The MVA005 is equipped with hard - and software functions to simplify installation, control and real-time
monitoring. Apart from standard, manual 4BS teach-in are EnOcean Remote Commissioning (ReCom)
operations available to teach and configure the device prior deployment or during operation. ReCom is
operated with separate from 4BS and periodically transmitted SIGNAL (0x09) telegrams. Single or multiple
ReCom commands must be executed within an 8 seconds time period after the UNLOCK command. ReCom
can be used to set its link-table and change device-internal parameters such as control loop gain, temperature
offset parameter or readout of its internal storage value (Refer to Section 9.5).

The drive can be restarted by means of manual RESET (Section 6.5). Holding the dial in one of the two end
positions for 10 seconds restarts the drive, runs a reference run and activates the 30-minute maintenance
interval. The drive then communicates for the next 30 minutes in a 2 minute interval. The ambient temperature
is the effective measured temperature of the ambient sensor. After the maintenance interval, the temperature
approximation and smoothing function restarts. Existing teach-in connections to the room controller and
remote commissioning settings are retained during manual RESET.

5 Energy-supply through thermal Energy Harvesting

The actuator generates the necessary electrical energy for operation by means of a thermoelectric generator
(TEG), which gains electrical energy from the temperature difference between radiator flow and room
temperature. During the heating season, excess energy is accumulated in the internal storage for operation in
transition periods and summer. The energy balance of the actuator is designed to allow operation through 365
days per year when used in typical radiator heating installations.

If, in exceptional cases, the storage voltage drop below a certain limit, the actuator reports this status to the
room controller and takes the protection position (50% valve opening or maintains the set value, whichever is
the higher). Subsequently, the actuator goes to sleep and waits until the memory is re-charged by the
thermoelectric generator back to a sufficient level. As soon as enough energy is available, the actuator
resumes normal operation.

The protection position ensures that the heating valve cannot calcify in an end position and freeze protection
is ensured. Unexpected room temperatures will occur.

Note: As long as the link table is not correctly described (no teach-in), the drive will remain in self-controlled
mode at 21°C and does ignore any room controller. Local inputs / changes to the setpoint temperature on the
dial are possible. Local entries lead to the immediate transmission of a data telegram.

6.5 Remarks Remote Commissioning

 The ReCom specification of the EnOcean Alliance applies
 ReMan / ReCom processes are executed in response to the signal sent by the drive (SIG)
 SIG telegrams are sent:

o Every time the drive is started from the installation position
o For drives in operation: Deactivate the drive by turning it against the left or right stop, hold

for 5 seconds until 1x green LED, release, 3x red LED

o Cyclic, during operation and parallel to regular 4BS communication in a default time interval

of 12 hours
NOTE: The SIG telegram interval can only be changed by means of ReCom (see product

specification).

 The maximum waiting time for an UNLOCK response to a signal telegram is 1 second

NOTE: Analogous to 4BS communication on A5-20-01 and A5-20-06

 ReCom starts with an UNLOCK, the required Default Security Code (SC) is 0x53C65E34
 Writing the link table and parameters requires prior modification of the Default Security Code
 Invalid SCs (0x00000000 and 0xFFFFFFFF) are automatically reset to the default SC
 Changing the SC plus writing the link table plus writing parameters can be done in one pass.
 The sequence of processing individual parameters or sequence of link table / parameter is freely

selectable.
NOTE: Note the Maturity time of the radio module with successive commands.

 The maximum available time window between UNLOCK and LOCK is 8 seconds
 If there is physical access to the device, the SEC CODE can be manually reset to its default value

 Device has received no radio answer and therefore transmits the user

offset a second time.

 With radio answer from the controller, only one telegram is sent
 The device receives its zero reference by a reference run. He loses it by

driving in mounting position.

 Note: A device that has been unscrewed from the valve without moving to

mounting position retains its zero reference!

 In this mode, the device communicates the actual measured

uncompensated ambient temperature. In addition, the radio period is 2
min.

 After 30 minutes, the device switches to normal operation.

7 Notes on radio operation

7.1 Transmission range

The radio transmission range is limited by both the distance between transmitter and receiver, and by
interference. Indoors, building materials play an important role. Major reflections and signal losses are due to
metallic parts, such as reinforcements in walls and metallized foils, which are used on thermal insulation
products.

Penetration of radio signals:

Material Penetration

Wood, gypsum, uncoated glass 90..100 %
Brick, chipboard 65.. 95 %
Reinforced concrete 10.. 90 %
Metal, aluminum facings 0.. 10 %

For an evaluation of the environment, please see guide values listed below:

Conditions Range / penetration

Line-of-sight Typ 30 m range in passages, up to 100 m in
halls
Plasterboard and wood walls Typ 30 m range through max. 5 walls
Brick and foamed concrete walls Typ 20 m range through max. 3 walls
Reinforced concrete walls & ceilings Typ 10 m range through max. 1 ceiling

Supply blocks and lift shafts should be treated as shields.

In addition, the angle at which the signal enters the wall has to be considered. A shallow angle increases the
effective wall strength as well as the attenuation of the signal. Whenever possible, signals should enter walls
perpendicularly. Alcoves should be circumvented.

For additional information, refer to the EnOcean White Paper “EnOcean Wireless
Systems – Range Planning Guide”.

7.2 Other interference sources

Common sources of interference are devices that generate high-frequency signals. These are typically
computers, audio-/video systems, electronic transformers and ballasts. The distance of the actuator to such
devices should be more than 0.5 m.

7.3 Loss of communication with the room controller

If the actuator cannot establish a dependable radio communication with the room controller, i.e. more than 6
times in sequence the room controller does not receive a radio signal, then the actuator switches to a
reduced radio pattern. The typical 10 minute radio period is extended to one transmission every hour,
reducing the energy consumption while radio contact is interrupted. In addition, the actuator enters the safe
position. Once the radio contact to the room controller recovers, the actuator reverts to requesting
instructions from the controller every 10 minutes.

User manual and Datasheet

8.2 Description of individual functions

Pls. also refer to the officially published EEP A5-20-06 description and Table 8.1

8.2.1 Setpoint Selection (SPS)

DIRECTION-2.
Selection whether A5-20-06 and the actuator is used with Valve Position (Controller running in the room or
building control system) or with its internal temperature control loop.

8.2.2 Operating mode (SP)

DIRECTION-2.

Setpoint Temperature °C:
The controller transmits the temperature setpoint for the internal controller (0 ... + 40°C, DB3.0 ... DB3.7 = 0
... 80). The use of a separate, external room temperature sensor is recommended whose room temperature
(DB2.0 ... DB2.7) is transmitted to the drive by the room controller as part of the A5-20-06 protocol. The internal
controller thus does not use the ambient temperature measured in the near field of the radiator, but the actual
room temperature. When operating with an internal temperature sensor, DB2.0 ... DB2.7 must be set to 0x00.
Every values not equal to zero (0x00) is interpreted as a valid room temperature value and thus will be used
and potentially result in faulty control behavior.

Valve position %:
The controller transmits 0 ... 100% (DB3.0 ... DB3.7 = 0 ... 100) and converts it into an actuating movement by
the actuator (0% = closed valve / 100% = completely open valve).

8.2.3 Local offset (LO)

DIRECTION-1.
The MVA005 local offset (LO) function offers a convenient way for end users to request temperature changes
locally at the actuator/radiator while the room control unit may be out of reach or may not be accessible at the
time of the desired temperature change. Nevertheless, LO follows a master (control unit) and slave (MVA005)
structure, which requires the control units to confirm any local change with corresponding data sent to the
respective actuator device.

Setpoint Temperature °C:
Local changes of +/- 1°C … +/- 5°C will be transmitted to the control unit as absolute °C value calculated from
the effective setpoint, plus or minus the desired °C value change. Example: Setpoint controller = 21°C + 2°C
local offset change = 23°C transmitted value.

Valve position %:
Local changes of +/- 1°C … +/- 5°C will be transmitted to the control unit as relative value.

8.2.4 Radio communication interval (RFC)

DIRECTION-2.
The 4BS radio communication interval of the actuator can be freely determined within the EEP specified range
by the room controller. This allows to e.g. reduce radio traffic and power consumption when outside of the
heating times (e.g. overnight, absence, setback mode), while in heating periods the response times of the
drive can be shortened. In default “auto” setting, the drive uses and varies between 2, 5 and 10 minutes based
on its internal flow temperature sensor. (2 minutes at T flow> 50 ° C, 5 minutes at T flow> 45 ° C, otherwise
10 minutes). Continuous operation with a radio interval of less than 5 minutes leads to increased energy
consumption and faster discharge of the internal storage. Short radio intervals must be coordinated with the
available flow temperature and heating times. If necessary, check the voltage of the internal memory by means
of remote commissioning.

MAR 2019 Page 20 / 33 MVA005_1DS_0319v2e.docx

MVA005
User manual and Datasheet

SIGNAL telegram cycle time can also be changed within the specified range through Remote Commissioning.
Pls. refer to the DDF and Section 9.5.

8.2.5 Summer bit (SB)

DIRECTION-2.
The actuator receives the status bit summer mode from the external controller through Standard 4BS message.
The valve closes while the radio communication interval is increased to once every 8 hours. It is possible to
wake up the iTRV through any local control setting. The actuator executes and transmits the local change and
continues with normal operation (unless the controller does transmit the summer bit again).

8.2.6 Valve recognition and ACO

The valve actuator does have a built-in valve recognition by means of force and distance measurement. Self­calibration is executed every time it moves to 0% position (full close). During operation the valve actuator does
a full stroke (self-calibration) once per week to avoid malfunction of the valve. It is not needed to trigger the
self-calibration (reference runs) through the control unit.

8.2.7 Window open detection (DWO)

DIRECTION-1.
Negative temperature changes within a given time period (2 minutes) measured with the ambient sensor are
used to detect open windows. The MVA005 immediately sets the DWO bit according to A5-20-06 and triggers
a 4BS standard telegram transmission to the room controller for further processing (e.g. closing the radiator
for 30 minutes). The window open detection function is limited to the transmission of data telegrams and setting
the DWO bit, no further internal reactions by the actuator apply.
Should the temperature fall further and below freeze protection temperature of 6°C, the drive automatically
opens to prevent from freeze related damages. DWO measurements are executed regularly within a 2 minutes
cycle and independent from the standard radio communication cycle set by the room controller. The window
open DWO is cleared as soon as the ambient temperature does not measure the specified changes over time.

8.2.8 Radio strength and com. error (RSS & RCE)

DIRECTION-1
The RSS (Radio signal strength) Bit is used to provide feedback about the radio signal strength of received
telegrams from its control unit, which will be helpful to analyze the radio quality in both directions. Received
telegram signal strength of <-80dBm will set the RSS bit. RCE (Radio communication error) is used to signal
radio loss following 6 consecutive missing data telegrams from the control unit to the valve actuator. In case
of RCE, the RSS bit will also be set.

8.2.9 Reference Run (Maintenance)

By setting the REF bit, the drive executes a reference run and restarts. The communication interval is set to 2
minutes (maintenance interval) for the next 30 minutes and the (uncorrected) ambient temperature measured
at the drive is transmitted. When the 30 minutes have elapsed, the temperature approximation and smoothing
restarts. 21 ° C are set as the default temperature setpoint, but they are overwritten by the first valid telegram
of the room controller.

Pls. contact Micropelt for further details and device description file (DDF, xml).

Description INDEX 0 = Ambient to Target Offset [K]

The ambient to target offset parameter [K] is related to a function to correct the ambient temperature

measured in the actuator. Due to its mechanical design and the near field of the radiator, the temperature

measured is subject to deviations relative to the actual room temperature. In automatic mode (0x00), the

drive uses its integrated flow sensor (valve adapter) to determine the actual room temperature value with

its internal approximation function. In all other settings than automatic mode, an absolute value is

subtracted from or added to the effective measured temperature. Example setting 0x07 = +3K: The

temperature output by the ambient sensor is the effectively measured temperature minus 3°C.

Description INDEX 1 = Radio communication interval [s/min]

The radio interval is only relevant when operating in radio communication failure mode (RCE, or controller

disabled) and controls the transmit interval of 4BS standard telegrams according to A5-20-06. In standard

operation, the 4BS defined radio interval will always override the parameter internal setting.

Description INDEX 11 = Ambient to Target Offset (A) Parameter

The so-called “A” parameter is used within the internal temperature approximation function to calculate

ambient temperature corrections based on actual measured flow (valve adapter) temperatures. In steady

sensor state, the A factor describes the level of parallel shift of the ambient temperature. Function [T

Approximated = T Ambient - ((T Flow - T Ambient) * Offset A Parameter)]. Differences in time constants

when radiators are turned on and off are compensated with an overlaying smoothing function to eliminate

temperature peaks. The smoothing function is based 2 internal arrays with 3 consecutive temperature

values that are compared in its deviations (<1°C) over a time period of 3 x 10 minutes.

Description INDEX 12 = Temperature Control Gain „P“ Parameter (only when SPS = 1)

The P parameter describes the gain/multiplier within the temperature control loop (only when SPS = 1) to

calculate the valve adjustment % value. The default value of 90 corresponds to a valve opening of 18%

when T Ambient the Setpoint temperature difference is 1°C. Note: The Automatic Ambient to Target Offset

(Index 0 = 0x00) mode does us the approximated temperature to calculate the valve opening value, which

is why the corresponding valve opening angles may be different to the above mentioned calculated value.

Description INDEX 14 = Signal Communication Interval

The signal communication interval can be changed from its default value of 12 hours to carry out Remote

commissioning operations with short(er) time intervals.
