Safety Guidelines

1. Follow the installation instructions.
2. Use the appliance
• according to its intended use
• in good condition
• with due regard to safety and risk of danger.
3. Note that the appliance is exclusively for use in the
applications detailed in these installation instructions.
Any other use will not be considered to comply with
requirements and would invalidate the warranty.
4. Please take note that any assembly, commissioning,
servicing and adjustment work may only be carried out
by authorized persons.
5. Immediately rectify any malfunctions which may
influence safety.

Description of Function

As throttle valve the Alwa-Kombi-4 limits the flow through the
circulation pipe. This is achieved either by manually closing
the valve to a certain position or automatically, when the valve
is equipped with a thermal actuator.
Manual presetting: the valve is preset according to a
calculated value and stays in that position. The flow of the
water is limited by the narrowed valve opening.
Automatic regulation: the valve is equipped with a thermal
actuator and preset to the desired water temperature. The
thermal actuator holds the water temperature at the valve to
the exact degree.
When the water temperature falls the valve opens and the
flow of warm water increases. When the water temperature
rises, the valve closes and shuts-off when the preset water
temperature is reached (except for a leakage rate).
With manual presetting the valve can only be set for optimal
operation under „full load". The automatic regulation process
allows a permanent regulation and by that an optimal supply
of all pipelines under most economical energy use.
As part of Honeywell´s "Kombi" family of valves, additional
functions can also be fitted and used after the valve has been
installed. The functions are carried out by installing adapters
into the cartridge spindle:
• The thermal actuator (preferably 50 - 60 °C [122 - 140
°F]) can be installed at any time without interrupting the
supply of warm water. The actuator is simply screwed
into the spindle and allows permanent hydronic
balancing based on the water temperature in the
circulation pipe
• The draining adapter is fitted to drain a pipe or riser and
can be removed when the draining process is finished.
It can be used with any Alwa-Kombi-4 potable water
balancing valve and also with any Honeywell Kombi-3-
plus heating/cooling balancing valve

• The sampling valve is used in conjunction with the drain
adapter and is used to determine chemical and
microbiological parameters

Assembly

5.1 Manual adjustment of Alwa-Kombi-4
following calculation
1. Close valve
2. Undo bolt and remove handwheel
3. Set the calculated value by turning the setting wheel to
the left or to the right
4. Replace handwheel, tighten bolt and open valve
5.2 Automatically setting the circulation
temperature
1. Take the scale value from the knurling on the
temperature controlled actuator and set on the valve as
described under 5.1 (figs. 1 - 3)
2. Fit handwheel and temperature controlled actuator
3. Tighten finger-tight to the stop
4. Open valve again
