2 Use and safety recommendations

 The metallic part of the unit’s housing serves as a heat sink. Be sure that the air circulation around it

is not obstructed by furniture, curtains, plants, or other objects.

 If the device has been stored in a cold environment, make sure that it resumes close to room

temperature before use. This is to prevent condensation from forming.

 The thermostatic radiator valve is designed for indoor use only. Do not allow the thermostatic radiator

valve to get wet. Its sensitive electronics can be affected.

 The unit is best cleaned with a dry or slightly damp cloth. Do not use aggressive cleaning agents or

solvents.

 Refrain from exposing the unit to environmental stress such as high mechanical forces (do not step

on it), strong vibrations, direct sunlight or extreme temperatures.

 The unit must not be disassembled or modified. In case you are unsure how to use the unit, please

get in touch with your beta test consultant.

 Be aware that correct operation can be affected by strong electromagnetic fields. Typical sources of

such are mobile phones, 2-way radios, RC transmitters, microwave ovens, electric motors.

 The housing contains actuated springs that can lead to injuries if released. For servicing, refer to

qualified service personnel.

 The thermostatic radiator valve has been designed and must solely be used for the purpose of

controlling a M30 x 1.5 heater valve. Any other use may pose a hazard to the device itself, to the
equipment involved, or to the health of the user.

 When operating the device in a workplace environment, be sure to observe the workplace regulations

that may apply.

 The self-powered thermostatic radiator valve is suitable solely for controlling water-filled heating

radiators. Any other use – including control of floor heating systems - is not permitted and can result
in damage. Do not disassemble or modify any part of the product. It is important to comply with the
safety notice included in these operating instructions.

MVA004 User manual and device specification

3 System description

This document defines the properties of Micropelt’s battery free thermostatic radiator valve MVA004. The unit
is directly mounted onto radiator valve bodies (M30x1,5 thread), where it controls the room temperature, based
on signals of a central controller. It is radio-controlled and powered by energy harvesting, so it neither requires
any cabling work nor does it consume batteries. It is designed for maintenance-free operation. The wireless
design makes the unit ideal for retrofit installation and cost-sensitive projects, where cabling cost is prohibitive.

At its heart, the MVA004 contains a thermoelectric harvesting module and integral energy storage. Beyond
this, it contains an electromechanical valve actuator, a radio module and a microcontroller that makes all parts
of the system work together. The actuator is equipped with a number of hard- and software functions that not
only allow remote-management (ReMan) and -commissioning (ReCom) but also features unique status and
monitoring capabilities. The device also offers a debug- and deployment-friendly radio communication interval
of 10 seconds for the first 10 minutes following its initial activation.

At its user interface, MVA004 has a red and a green LED, which are described in more detail in section 4. Two
internal temperature sensors are used with a) its internal temperature controller and freeze protection control
(ambient sensor) and b) the automatic radio duty cycle control of 2, 5 or 10 minutes (flow temperature sensor).

 MVA004 is operating with EnOcean standard EEP A5-20-01 (4BS) in either valve position or set

temperature mode. According to the standard protocol, the drive reports to the room controller every 2/5 or 10
minutes (auto radio interval based on flow temperature) and transmits the value of its valve position. The room
controller responds with either a new control value in the value range 0% (valve closed) to 100% (valve
maximum open) or setpoint temperature (0 ... 40 ° C). When the setpoint changes, the actuator motor moves
the motor to the new position.

 When operating with the setpoint temperature, it is recommended to use a separate, external room

temperature sensor, which transmits the room temperature to the room controller, which then transmits it to
the drive (as described in A5-20-01 protocol). Without external room temperature, the internal controller uses
the sensor installed in the drive (picture page 5). By heat input from the radiator in the drive, there are
deviations between the measured and actual room temperature, which are compensated by means of an
integrated correction function.

 The actuator is in the delivery state in mounting position (motor positon is fully retracted). The actuator has

valve recognition. Unmounted but activated will automatically move the motor back to mounting position and
switch-off the actuator.

 The internal energy storage of the actuator is fully charged upon delivery, so that sufficient energy is

available for installation and up to approximately one year of operation. The drive works 365 days a year.
When the heating system is switched on, the actuator then supplies itself independently via the heat of the
heating circuit. Due to the surplus of generated energy in winter, the internal storage provides sufficient energy
for the year-round operation including transition periods and summer.

 In the event of a radio failure (6 unsuccessful communication attempts), the internal temperature controller

is activated and the radiator is regulated to a preset 21 ° C. A change of the radio interval does not take place.
The drive goes into normal operation as soon as the radio communication is restored.

 When operating in unheated rooms, the internal memory will eventually be discharged. The drive then

moves to the 50% position to recharge the memory. Operation of the drive in unheated rooms is not
recommended

MVA004 User manual and device specification

 MVA004 is designed for low power operation. Therefore, all ReMan and ReCom operations are internally

time limited and must be executed within less than 5 seconds. It is strongly recommended to use script
command sets (contact Micropelt for examples) and execute ReMan only for initial teach over the air (Link
Table) and device configuration following its initial deployment.

 MVA004 has a button lock after one hour function integrated that will prevent from unintended use.

4 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.

6 Notes on radio operation

6.1 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”.

6.2 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.

6.3 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.

7.2 Description of individual functions

Based on section 7.2

7.2.1 Setpoint Selection (DB1.2, RCU to MVA004)

Selection whether A5-20-01 and the actuator is used with Valve Position (Controller running in the room or
building control system) or with its internal temperature control loop.

7.2.2 Valve position [%] and Set temperature [°C] in actuator mode (DB3, RCU to MVA004)

The external radio partner transmits the temperature setpoint for the internal controller (0 ... + 40°C, DB3.7 ...
DB3.0 = 0 ... 255). The use of a separate, external room temperature sensor is recommended whose room
temperature (DB2.7 ... DB2.0) is transmitted to the drive by the room controller as part of the A5-20-01
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, DB2.7 ... DB2.0 must be set to 0x00. Values not

equal to 0x00 are interpreted as sent room temperatures and thus lead to faulty control behavior.

Valve positon (%):The external radio partner transmits a 0 ... 100% control signal (DB3.7 ... DB3.0 = 0 ...

100) and converts it into an actuating movement by the actuator (0% = closed valve / 100% = completely
open valve).

7.2.3 Summer Mode (DB1.3)

When the actuator receives the status message „Summer mode ON“ from the external radio master, then
the valve opens and the transmit/receive interval is increased from 2/5/10 minutes to 8 hours. It is possible to
wake up the iTRV through 1 x pressing the push button. Then the iTRV receives the new setting from the
room controller.

7.2.4 Recognition of valve position and reference run

The valve actuator recognizes during the teach-in the closing position of the valve. During operation the
valve actuator does a full stroke (self-calibration) after every 30 movements, to avoid malfunction of the
valve. It is not intended to trigger the recognition of the valve position via room controller.

7.3 Example of a radio protocol

Radio protocol of valve actuator MVA to server /controller /gateway

Example in HEX "0x32 0x70 0x89 0x08"

 DB3.7…DB3.0 = 0x32 = 50: valve position is 50%

 DB2.7…DB2.0 = 0x70 includes

o DB2.4 = 1 Energy storage capacity sufficient

o DB2.5 = 1 Energy storage charged

o DB2.6 = 1 Harvesting active

 DB1.7…DB1.0 = 0x89 = 137: Internal temperature = 40*DB.1/255 = 40*137/255 = 21,5 °C

 DB2.7…DB2.0 = 0x77 = 119: room temperature = 255 - 119 = 136 => 40 * 136 / 255 = 21,3 °C

 DB1.7…DB1.0 = 0x00:

o DB1.3 = 0: regular default radio cycle (no summer mode)

o DB1.2 = 0: DB3.7…DB3.0 is set to valve position %

 DB0.7…DB0.0 = 0x08: Data telegram

SET_TEMP: Example in HEX "0x80 0x81 0x04 0x08"

 DB3.7…DB3.0 = 0x80 = 128: New target temperature is 40 * 128 / 255 = 20,1°C

 DB2.7…DB2.0 = 0x81 = 129: room temperature = 255 - 129 = 126 => 40 * 126 / 255 = 19,8 °C

 DB1.7…DB1.0 = 0x04:

o DB1.3 = 0: regular default radio cycle (no summer mode)
