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
7. Set Outdoor-controlled heating curve.
The Left-hand side buttons change the curve
(buttons 1-2), Up&down buttons (5) are for paral-
lel displacement (finetune of inner temperature)
AM40 has the following default curves:
Underfloor heating Curve 2
Radiator heating Curve 4
Type of building aect 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

AM40 with Outdoor Temperature Control:
A. If Your house is constantly too cool or warm,
press up/down keys (5):
Adjust room temperature with up&down keys (5)
and accept with OK key.
This control adjusts the room temperature
with the assumed room degrees from the start
situation
B. If Your house is too cool or too warm in cold
period, press key (4) twice:
Select higher curve if it’s too cool or lower curve
if it’s too warm.
Higher curve with key 1
Lower Curve with key 2
Curves from 0.2 up to 5.0 in 0.2 steps
from 5.0 up to 9.5 in 0.5 steps
Room Temperature Control
AM40 accessories
In this chart You can see formula between
outside temp and supply water temp with dif-
ferent curves
Example:
-10 ºC outside temperature
Supply water +40 ºC using curve 4
Supply water +30 ºC using curve 2
Notice that min limit and max limit aect how
hot/cool supply water can be!
To check those values press key(4) once when
you are in the basic screen.
Modifying is also possible in same menu with OK
button(4) and up&down buttons (5)

Vexve AMV range:
The pin is already in the left-hand side of the
valve. Only the Termomix adapter from the instal-
lation 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 instal-
lation 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. At-
tach the sensor cable to IN1 connector in AM40.
Do the same in circuit 2 if included, attach sen-
sor 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!
