Safety Notes
Prior to assembly and commissioning
to avoid injury of persons and damages
of the devices, it is absolutely necessary
to carefully read and observe these
instructions.
Necessary assembly, start-up, and
maintenance work must be performed
only by qualied, trained and authorized
personnel.
Prior to assembly and maintenance work
on the controller, the system must be:
- depressurized,
- cooled down,
- emptied and
- cleaned.
Please comply with the instructions of the
system manufacturer or system operator.
Denition of Application
The controller is in combination with
electrical actuators (AMV(E) 1_,2_, 3_, 150)
used for:
- ow and temperature control (AHQM) or
- di. pressure and temperature control
with ow limitation (AHPBM-F)
in water and water glycol mixtures for
heating, district heating and cooling
systems.
The technical parameters on the product
labels determine the use.
Assembly
Admissible Temperatures
1
Admissible Installation Positions
2
The controllers can be installed in
horizontal or vertical pipes with
(connection neck for) electrical
actuator oriented upwards.
Electrical actuator
Installation positions for electrical
actuator AMV(E) have to be observed as
well. Please see relevant Instructions.
Installation Location and
Installation Scheme
AHQM return mounting
4
AHQM ow mounting
5
AHPBM-F ow mounting
3
AHPBM-F controller can only be installed in
ow pipeline in direct-connected heating
system with mixing loop.
Valve Installation
6
1. Clean pipeline system prior to assembly.
2. The installation of a strainer
in
front of the controller is strongly
recommended.
3. Install valve
• The ow direction indicated on the
product label or on the valve must
be observed.
• The valve with mounted weld-on
tailpieces may only be spot welded to
the pipeline .
The weld-on tailpieces may be welded
only without the valve and seals!
If these instructions are not observed,
high welding temperatures may
destroy the seals.
• Flanges
in the pipeline must be in
parallel position and sealing surfaces
must be clean and without any
damage.
Tighten screws in anges crosswise
in 3 steps up to the maximum torque
(50 Nm).
4. Caution:
Mechanical loads of the valve body by the
pipelines are not permitted.
Mounting of electrical actuator
7
Place electrical actuator AMV(E) on the
valve and tighten union nut with wrench
SW 32.
Torque 25 Nm.
Other details:
See instructions for electrical actuator
AMV(E).
Impulse tube mounting
8
• Which impulse tubes to use?
Use impulse tube set AH
• Connection of impulse tube in the
system
• Connection to the pipeline
9
It is strongly recommended to install
the impulse tube to the pipeline
horizontally or upwards .
This prevents dirt accumulation in the
impulse tube and possible malfunction
of the controller.
Connection downwards is not
recommended
.
Insulation
10
The controller may also be insulated.
Insulation of electrical actuator
AMV(E) is not allowed.

Start-up
12
Filling the system, rst start-up
1. Slowly open shut-o valves that are
possibly available on the impulse tube
(AHPBM-F).
2. Open valves in the system.
3. Slowly open shut-o devices
in the
ow pipeline.
4. Slowly open shut-o devices
in the
return pipeline.
Leak and Pressure Tests
Pressure tests should be carried out prior
to the installation of the electrical actuator.
This guarantees that the valve is opened.
Before pressure test, open the adjustable
ow restrictor by turning it to the left
(counter clockwise).
Adjustable ow restrictor has to be
moved by hand not by tool.
Pressure must be gradually increased at
the (+/-) connection .
Non-compliance may cause damages at
the actuator or the valve.
A pressure test of the entire system
must be carried out in accordance with
manufacturer’s instructions.
The maximum test pressure is: 1.5 × PN
PN - see product label!
Putting out of operation
1. Slowly close shut-o devices in the
ow pipeline.
2. Slowly close shut-o devices
in the
return pipeline.
Settings
Dierential Pressure Setting (AHPBM-F)
AHPBM-F is controller with xed ∆p setting.
Therefore setting of ∆p is not required.
If the required dierential pressure is not
attained, a cause may be a too small
pressure loss in the system.
73695230 DH-SMT/SI VI.LR.B1.02 © Danfoss 11/2007 6
Flow Rate Setting (AHQM)
The ow rate is adjusted by means of
limitation of control valve stroke .
There are two possibilities:
1. Adjustment with the ow adjusting
curves,
2. Adjustment with heat meter.
Pre-condition
(Min. di. pressure over the valve)
To achieve maximum ow rate the pressure
dierence Δp
v
across the control valve
must be at least:
p
min
= 0.5 bar
Adjustment with ow adjusting
curves
13
The system don’t need to be active for
being adjusted.
1. Close control valve
by turning the
adjustable ow restrictor to the right
(clockwise) to its stop.
Adjustable ow restrictor has to be
moved by hand not by tool.
2. Select ow adjusting curve in the
diagram (see page 4).
No
Necessary
ow rate
Revolutions of
adjusting throttle
3. Open the adjustable ow restrictor
by determined number of revolutions to
the left (counter clockwise):
Adjustable ow restrictor has to be
moved by hand not by tool.
4. The setting of the valve stroke is
completed, continue with step 2 in
section Adjustment with Heat Meter.
Note:
The setting may be veried with help of a
heat meter if the system is in operation,
see next section.
Flow Adjusting Curves
14
Adjustment with Heat Meter
15
Pre-condition:
The setting can be carried out when the
electrical actuator AMV(E) is dismounted.
The system must be in operation. All units
in the system or a bypass must be
completely open.
1. Observe heat meter indicator:
- turning to the left (counter
clockwise)
increases the ow rate
- turning to the right (clockwise)
decreases the ow rate
Adjustable ow restrictor has to be
moved by hand not by tool.
After the adjustment has been completed
16
:
2. Install the electrical actuator
, see
section Mounting of electrical actuator.
3. Shortly throttle the system and then
re-open it (e.g. by means of the
electrical actuator).
4. Verify ow rate.
The control valve setting is completed.
5. Electrical actuator
may now be
sealed
.
