MVA003 User manual and device specification

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 wi reless design ma kes
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,
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.



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.

occurs once every 10
seconds for the
duration of 10 minutes,
then relaxes to once
every 10 minutes.

Success: Single red

Failure: 3x red flash,
unit returns to mounting
position = OFF

Controller or gateway
either not present or
not in pairing mode, so
that pairing fails

Unit is not attached to
an appropriate valve,
an inadequate adapter
is being used,
motor or gear error,
unit is not paired,
unit cannot contact the
controller

4) Get new target value
(while buttons not
locked)

5) Return to mounting
positon

6) RESET
from normal operation

 One hour after this

action, the pushbutton
switch will lock and can
only be unlocked, by
performing RESET
Press pushbutton once.
Unit requests new
settings from controller
or gateway
Press pushbutton twice
within 2 seconds.
Unit moves the plunger
fully in and sets inner
stop reference anew,
then turns off,
remaining in mounting
position
Push and hold the
button for at least 10
seconds:
Unit moves to 50%,
resets, awakes, moves
the plunger fully in,
does the run-in

Success: Single red
flash

Failure: 3x red flash
3x red flash, unit
returns to mounting
position = OFF

After 10 sec have
elapsed and RESET is
triggered:
Single red flash

For run-in sequence,
see item (3)

Unit is not paired, unit

3 Notes on radio operation

3.1 Transmission range

The radio transmission range is limited by both the distance between transmitter and receive r, and by
interference. Indoors, building materials play an important role. Major reflections and si gnal 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.
