1 Introduction
This document defines the properties of Micropelt’s battery free thermostatic radiator valve MVA003. The unit
is directly mounted onto the radiator valves, 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 MVA003 contains a thermoelectric harvesting module and integral energy storage. The internal
storage is charged throughout the heating season from surplus energy produced by the harvesting element.
This allows the actuator to operate 365 day/year. Beyond this, it contains an electromechanical valve actuator,
aradiomoduleandamicrocontroller thatmakes allparts ofthe system work together. Theactuator isequipped
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.
MVA003 is operating with EnOcean standard EEP A5-20-01 (4BS) valve position or set temperature.
MVA003 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.
MVA003 has a button lock after one hour function integrated that will prevent from unintended use.
The unit’s user interface consists of one user button and one LED. An ambient temperature sensor serves
both the temperature control and the antifreeze function. The actuator fits a standard radiator valve M30 x 1.5
mm.

3 Notes on radio operation
3.1 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”.
3.2 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.
3.3 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.

Setpoint Selection
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.
Valve position / Set temperature in actuator mode (DB_3)
Based on 4.2.1:
Target temperature (°C): The room control unit transmits a target temperature between 0°C and +40°C
which will be used as by the internal control loop to calculate valve positions.
It is recommended to also transmit the RCU temperature used to operate the MVA internal control loop
(p-controller with GAIN).
Valve positon (%): From the external radio master a control value of 0..100% is transmitted and the valve
actuator executes a valve movement (0% = valve closed / 100% = valve open).

MVA003 User manual and device specification
Preliminary
May 2017 Page 8 of 20 1DSMVA003_0217v7e
Summer Mode (DB_1.Bit_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 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.
Recognition of valve position
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.
4.3 Example of a radio protocol
Radio protocol of valve actuator MVA to server /controller /gateway
Example in HEX "0x32 0x60 0x89 0x08"
DB.3 = 0x32 = 50: valve position is 50%
DB.2 = 0x60: DB2.Bit_5 = 1 (Energy storage charged) / DB2.Bit_6 = 1 (Harvesting active)
DB.1 = 0x89 = 137: Internal temperature = 40*DB.1/255 = 40*137/255 = 21,5 °C
DB.0 = 0x08: Data telegram
Radio protocol from server /controller /gateway to valve actuator
VALVE POS: Example in HEX "0x05 0x81 0x00 0x08"
DB.3 = 0x05 = 5: new valve position is 5%
DB.2 0x77 = 119: room temperature = 255 - 119 = 136 = 40*136/255 = 21,3 °C
DB.1 = 0x00: DB_1.Bit_3 = 0: regular radio cycle 10 Minutes (no summer mode)

7 User Control description
7.1 Installation with Manual Pairing
Pairing / Teach-In, Mounting position and OFF
Set the EnOcean controller or gateway to pairing mode. Then take the MVA003 from its packing and press
the button at least twice within 2 seconds. MVA003 confirms successful pairing by a single flash of the red
LED. An unsuccessful pairing attempt is indicated by a 6x flash of the red LED. In this case, check the
setting of the EnOcean gateway and repeat the pairing procedure. In case the MVA003 is not in mounting
position already, it now moves to mounting position (= shipping condition = OFF). It does so, even if the
pairing attempt failed.
Attaching the unit to the radiator valve
After pairing, the MVA003 is always in mounting position, e.g. the plunger is moved fully inwards so that
the unit can be attached to a radiator valve without force. Remove any existing thermostatic head that may
be affixed to the radiator valve. Assure that the valve seat and the valve thread are clean, then place the
MVA003 against the valve seat and tighten the connecting nut. If appropriate, secure the connecting nut
through a theft-protection bracket.
Activating the unit
Press the MVA003 button once for < 1 sec, in order to initiate the run-in sequence. This calibrates the unit
against the particular valve, determining closed-valve and open-valve positions. A singlered flash indicates
success and a triple red flash indicates failure. In the event of failure, the MVA003 will return to mounting
position and power down. In this case, verify that the unit is correctly and firmly attached to the valve. In
case of an adapter piece being used, verify that it’s the correct adapter for the valve and that it is installed
according to the instructions. Once everything is checked and any errors are corrected, repeat this
paragraph.
Start using MVA003
After activation, MVA003 powers up its radio and contacts the EnOcean controller / gateway, requesting
new settings. It does so every 10 minutes; however, for the first 10 minutes after activation, the radio
communication period is 10 seconds as to speed up installation and test of a freshly installed unit.
Return to mounting position
Double press the button. The device will turn the motor back to mounting position and switch off.
RESET
The MVA003 RESET function is useful if the unit exhibits inexplicable behavior. It is being triggered by
pressing the pushbutton for at least 10 seconds. A single red flash confirms that the 10 sec have elapsed
and the reset-sequence starts. Now it depends if the unit was in normal operation or in mounting position
(=off).
If MVA003 was in normal operation, the valve is opened 50%, then the actual reset is applied to the unit.
The motor moves fully inward, then goes through the run-in sequence and finally enters normal operation.
At first, the radio communicates every 10 seconds. After 10 minutes have elapsed, it switches to the user-
set radio communication period (default is 10 minutes)
If MVA003 was in mounting position (=off), the motor moves against the inner end stop, thereby
recalibrating. There is no further motor movement. The unit remains in mounting position and switches off.
Removal of MVA003 from the Valve
Press the pushbutton twice. If the motor starts moving, wait for it to stop. Loosen the connecting nut,
remove the unit and place it into its original packing.

7.2 Installation with Remote Commissioning
Attaching the unit to the radiator valve
Take the MVA003 from itspacking. It should be in mounting position, e.g. the plunger is moved fully inwards
so that the unit can be attached to a radiator valve without force. Remove any existing thermostatic head
that may be affixed to the radiator valve. Assure that the valve seat and the valve thread are clean, then
place the MVA003 against the valve seat and tighten the connecting nut. If appropriate, secure the
connecting nut through a theft-protection bracket.
Activating the unit
Press the push-button of the MVA003 buttons once for < 1 sec, in order to initiate the run-in sequence. This
calibrates the unit against the particular valve, determining closed-valve and open-valve positions. A single
red flash indicates success and a triple red flash indicates failure. In the unlikely event of failure, start over
from mounting position. Section 0 explains how to get there.
Start using MVA003
After activation, MVA003 powers up its radio and contacts the EnOcean controller / gateway, requesting
new settings.
The controller / gateway then switches the MVA003 into Remote Commissioning mode by responding
using Remote Management command UNLOCK instead of 4BS (refer to section 4).
In order to accomplish the configuration of a freshly installed unit as fast as possible, the radio first
communicates every 10 seconds. After 10 minutes have elapsed, the communication period relaxes to the
default 10 minutes.
Return to mounting position
Double press the button. The device will turn the motor back to mounting position and switch off.
