1. Mounting the AMER module on
AMV 323/423/523
A) Mount AMV motor on valve (fig. 1.1).
B) Remove lid from AMV motor (fig. 1.2).
C) Fit staybolts supplied with the AMER
module (fig. 1.3). If replacing a
module, the staybolts must also be
replaced.
D) If the AMER module is to be set up
using mains voltage, follow the
instructions in section 6: Automatic
setting up of AMER module .
E) Mount the AMER module in the motor
by pushing it half in over the
staybolts. Connect module leads in
motor terminal board (fig. 1.4) and
then push module fully into place.
Note: Before connecting the control
signal from the regulator to the AMER
24 V module, mains voltage must be
connected correctly as described in
section 6. Mains voltage.
2. Fuse (230 V ~ only)
A) The fuse can be removed/replaced by
turning the fuse holder in the direction
of the arrow (figs. 2.1 and 2.2).

4. Control voltage
Normal operation
The control signal from terminal 61
(P regulation) or from terminal 62
(PI regulation) must be connected to
terminal 41.
Operation with override
The control signal from terminal 61
(P regulation) or from terminal 62
(PI regulation) must be connected to
terminal 41.
The override signal (e.g. from a clock or
frost thermostat) must be connected to
terminal 40 and terminal 10 or 12.
Override can be annulled via a switch.
Always use the contact set that has low
contact resistance.
Note: Plug in the module only when
mains voltage is connected and checked
as described in section 6. Mains voltage.

5. Connection of temperature sensor
A Pt 1000 Ω temperature sensor must
be connected to terminals 21 and 22
(fig. 4.1).
6. Mains voltage
AMER 24 V
Terminal 6 must be connected to phase
(L) and terminal 7 must be connected to
neutral (N) (fig. 4.1). Do not swap the
leads when connecting mains voltage to
the AMER 24 V module; it will damage
the module. Using a measuring
instrument, check as shown in fig. 6.1 to
make sure that 24 V mains is connected
correctly. If the measured voltage
exceeds 3 V ~, mains voltage is
incorrectly connected. When mains
voltage is correctly connected, plug in
the regulator control signal (fig. 6.2).
AMER 230 V
There are no special instructions
regarding lead connection for mains
voltage, i.e. mains voltage is connected
to a transformer in the AMER 230 V
module.
7. Valve travel setting ("Stroke" set)
in the AMER module memory
Manual setting of AMER module
(Normal when adjusting motor valves
individually).
- Approx. 5 s after mains voltage is
connected, the red LED (by the
function switch) lights up (fig. 7.1).
- Press in the "Stroke" set button with a
screwdriver (fig. 7.1).
- The LED will flash while the motor
runs through a close/open cycle.
- When the valve travel has been
registered in the AMER module
memory, the LED again lights up
constantly and manual setting is
complete.
Automatic setting of AMER module
(Normal when setting several motor
valves at same time).
- Before mounting the AMER module,
clip the jumper on its underside
(fig. 7.2). (Note: it is still possible to
set the AMER module manually after
the jumper has been clipped).
- Switch on mains voltage until the red
LED (by the function switch) lights up
constantly.
- Switch off mains voltage for a
minimum of 6 s. (LED goes out).
- Switch on mains voltage for between
1 and 5 s. (The LED should remain
out).
- Switch off mains voltage for a
minimum of 6 s.
- Switch on mains voltage. The LED
will flash and the AMER module starts
automatic setting.
- When automatic setting is registered
in the AMER module memory, the
LED lights up again constantly and
automatic setting is complete.

Note: When the jumper is clipped, the
AMER module opens and closes the
valve completely, both in connection with
automatic setting and with possible
current failure during operation.
Therefore BE CAREFUL - there is a risk
of scalding when, for example, an AMER
module with clipped jumper is used for
regulating service hot water.
