3Product description
PrimoBox AZB mixing units are available in versions supplying two
or three heating circuits.
PrimoBox AZB mixing units with a low-loss header secure the correct
flow rate of the medium and the correct operation of the pumps in all
heating circuits. They also allow obtaining different flow temperatures
of individual heating circuits.
The PrimoBox AZB mixing unit is enclosed in a metal cabinet. Inside
the cabinet there is a manifold with a built-in low-loss header ensuring
independent operation of individual heating circuits, while minimizing
the impact of circulation pumps on the heat source.
There are versions with heating circuits without mixing, with mixing
by an ARM ProClick actuator on a rotary valve or by mixing with
an ATM thermostatic mixing valve.
Two-section versions of AZB mixing units are made based
on the same manifold as three-section version, but only two pairs
of connections are used.

3.2 Dimensions
Fig. 2: Dimensions of the AZB mixing unit
In the two-zone version equipped with two ATM thermostatic mixing
valves (Art. No. 76 211 00), middle and right connections are used
to facilitate operation of the thermostatic valve knobs.
3.3 Operation
The mixing unit PrimoBox AZB with low-loss header is designed
to divide the heating medium flow from the boiler circuit into two
or three heating circuits. The manifold used with a built-in low-loss
header eliminates the need to balance the primary circuit of the boiler
with other circuits. This ensures smoothness and high efficiency
of the installation operation regardless of the current hydraulic
conditions and the current demand for heating power.
Using the PrimoBox AZB mixing unit with low-loss header allows
reducing the use of number of fittings and pipes necessary to perform
individual installation circuits, and helps to organize and simplifie
the entire installation.
Instruction manual
8 PrimoBox AZB mixing units with low-loss header 200 and 300 series in cabinets
Shut-off valves with thermometers
AZB mixing units are supplied with built-in shut-off valves to facilitate
product maintenance. Check valves have been built into the shut-off
valves. Space for temperature sensors has also been prepared.
The valve knobs contain thermometers to control the temperature
of the heating medium. By turning the knob by 45°, the non-return valve
is forced to open to enable system maintenance and system filling.

button
To mount the ARM ProClick ac-
tuator on the mixing valve
of the AZB unit, the mixing
valve must be set to "50%
opening", i.e. the center of its valve is exactly halfway between the hot
water inlet and the cold water inlet. Then slide the actuator onto the
mixing valve until the ProClick mechanism locks on it. When mounting
the ProClick actuator on a rotary valve, pay attention to the current
position of the valve cover. The valve stem should be positioned
as in Figure 19, and the actuator position indicator should show half
the scale. If the valve is in a different position, set it manually (using
a flat screwdriver, for example) as shown in Fig-
ure 19. If the indicator on the actuator does not
indicate the center of the scale, switch it to man-
ual operation mode, set the actuator with the al-
len key so that the indicator is in the center of
the scale. After putting the actuator
on the valve, switch back to automatic mode.
