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

MVA005
User manual and Datasheet
MAR 2019 Page 5 / 33 MVA005_1DS_0319v2e.docx
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 re-
established.
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.

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.

* Remarks to the flowcharts 6.5 and 6.6
"no response within 1 sec” 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
"does (not) have a valid zero point
reference”
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!
"maintenance mode" 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.
