B

Vexve AMV range:

The pin is already in the right-hand side of

the valve. Only the Termomix adapter from

the installation kit should be installed on the

stem. The pin side may be changed if the

engine position requires it.

Place valve and motor unit in zero position.

Termomix valves:

A suitable pin screw and adapter from the

installation kit should be installed.

Valve assembly

Connect motor(s) to mixing valve with

included connection adapters.

Motor units are suitable for valves like:

MUT, ESBE (not VRG), LK, Belimo, Barberi,

Vexve.

Esbe VRG serie valves has separate

adapter part available (Vexve nr.1920117)

( A ) Check the valve operational direction

before installation.

( B ) In manual mode check that valve/

motor combination turn 90-degrees with

reasonable torque!

If AM40 consist also

Wireless Room unit:

Connect RF-antenna unit to

RF-connector in AM40, place

antenna as high as possible.

Antenna can be lenghtened

for better RF-reception with ready wire.

(10 meter extension cord Vexve nro.

1920096)

Relay control is used for example pump

control, in that case 230 VAC wire must

be connected to go thru R1 connector by

opening the cover of AM40.

Notice 230 VAC connection needs

professional electrician!!

Contact info connector IN4 connector can

be a normal on/o switch. (Away switch as

default set). It is also usable for future temp.

sensor use.

Attach the AM40 Control Unit with

convenient location with included assembly

parts.

The device can be attached to the wall with

the screws included.

Also 35 mm DIN-rail connectors are ready

in the back of the CPU.

Connect motors to M1 & M2 connectors in

AM40, M1 if only one circuit is in use.

Place Supply Water sensor 1 to pipeline

5-25 cm from mixing valve using pipe

attachment ties. Attach the sensor cable to

IN1 connector in AM40.

Do the same in circuit 2 if included, attach

sensor cable to IN2 connector in AM40.

Attach the external temperature sensor

using wall mount box to suitable place in

outer wall. (Secure location, not direct

sunlight or snow / rain to sensor box).

min.

2 m

Attach the sensor cable to IN3

connector in AM40.

If necessary the sensor wire can be easily

extended with ready to use 10 meter

extension cord (Vexve nro. 1920096).

Cable lenghtening must be located inside

the building!

First start

When You turn on the Power

for the ﬁrst time to AM40

The device ask for basic information that

You can change with arrow keys and

accept the choices witk OK key.

1. Select language

2. Set time

3. Set date

4. Set circuit 1 heating system type,

underﬂoor heating or radiator heating

5. Set the valve operational direction,

clockwise or counterclockwise

6. Set Your own supply water temp. limits

or accept the factory default settings

8

9www.vexve.ﬁ.

7. Set Outdoor-controlled heating curve.

The Left-hand side buttons change the

curve (buttons 1-2), Up&down buttons (5)

are for parallel displacement (ﬁnetune of

inner temperature)

AM40 has the following default curves:

Underﬂoor heating Curve 2

Radiator heating Curve 4

Type of building aect to curve selection as:

Old houses with bigger curves

New houses with smaller curves

Curves: 0.2 - 5.0 in 0.2 steps

5.0 - 9.5 in 0.5 steps

Parallel displacement is not adviced to be

used when You start AM40 for the ﬁrst time.

For end user ﬁnetuning is very easy in

basic display with up&down buttons (5) if

there is constantly too high or low temp in

living area.

When You use a wireless room unit it is

natural to control living area temperature

with RF-Room unit. In that case You can

accept factory default curves in this step.

See outside temp vs. supply water temp.

curve at the end of this manual!

8. After setting up above information You

are in the basic display

Situation in the basic screen:

The outside temperature is displayed top

right corner and the line below it shows

that outside temperature control is in use,

supply water temp is seen next to heating

type symbol.

(above You can see outside controlled

radiator heating where supply water is

45-degrees)

Fine adjustment to room temperature can

be done with up&down buttons (5).

The expected change in room temperature,

(+/-) degrees is showed on the screen with

large digits

Adding a Wireless Room Unit

Wireless Room Unit for the AM40 ECU:

product nr. 1140041: Pack A, Wireless

room Unit & Transmitter

Mechanical assembly:

Connect RF-antenna unit to RF-connector

in ECU, place antenna as high as possible.

Antenna can be extended for better RF-

reception with ready coupled wire.

(10 meter extension cord Vexve nro.

1920096)

Remove the protective plastic from the

batteries in Room Unit and check that “RU”

appears on the screen

After mechanical assembly press button 1

two times to reach the Main menu.

Main menu >> go to Device settings >>

go to Communication menu using

up&down buttons (5)

In Communication menu >> go to RF-

devices where You ﬁnd RF-devices section

Room unit must be powered and word RU

must be on the screen!

(If there is something else on the screen You

must press the commissioning button D on

the room unit with tip of a pen. Select DE

fa

from the commissioning menu and select

Yes for that.

10

11www.vexve.ﬁ.

Pairing starts in AM40 ECU when OK

button is pushed. Immediatelly after that

Right button in room unit must be pressed

too. Now LCD-screens show the texts

”Pair” / “Device pair-up”

After few seconds “Found AM Room Unit”

& “Pair ok” appears on the screens. Now

You must choose the right heating circuit

which room unit controls (H1 default / H2)

and after that all basic data is copied from

AM40 ECU to room unit memory..

You can leave Room Unit menu by pressing

button B (ECO-button)

Room unit menus >>

Adding second heating circuit

For controlling second heating circuit with

AM40 You need second valve motor and

supply water temperature sensor

Product nr. 1140042: Pack B, heating

circuit 2 motor package includes all

necessary parts

Mechanical assembly:

Mechanical assembly is same as in heating

circuit 1 except:

Motor Unit connected to M2 connector.

Supplywater sensor connect to IN2

connector.

A

B

( A ) Check the valve operational direction

before installation.

( B ) In manual mode check that valve/

motor combination turn 90-degrees with

reasonable torque!

After mechanical assembly press button 1

two times to reach the Main menu

Up/down buttons (5) are used for moving in

menus OK button (4) is for enter / accepting

values.

button is for undo/exit.

Main menu >> go to Device settings >> go

to H2 options

12

13www.vexve.ﬁ.

For second Heating Circuit there are three

dierent heating types:

· Radiator heating

· Floor heating

· Constant temperature heating mode to

maintain supply water in adjusted value.

Next You choose the operational direction

of valve and last Control type. Notice that

Control type Room Controlled can be used

when RF Room Unit is in use.

Control type info

Outdoor temperature controlled

system using curves

· curve adjustment is always needed

· even when room compensation is in use

with RF-Room Unit You must roughly

adjust right curve (+/- 5 degrees)

Indoor temperature controlled system

àla AM20-W patented indoor regulation

algorithm that don’t need heating curve

settings at all.

· you can use this control program when

RF-room unit is in use

· no curve settings at all

When You have made the choises press exit

button (3) to enter basic screen.

From now on You ﬁnd Circuit 1 and Circuit 2

basic screens behind the button number 1.

Measured values and Main menu are also

found behind that button.
