8. Commissioning
8.1 Setting outlet pressure
(AQA therm HFB-1717 BA)
The factory setting of the pressure reducer is 1.5 bar.
The system pressure should be at least 2 bar higher
than the outlet pressure setting.
1. Close the shut-off ball valve on the inlet side of
the AQA therm HFB-1717 BA and on the outlet
side of the AQA therm HES.
- The outlet-side shut-off ball valve on the AQA
therm HFB-1717 BA must remain open.
2. Depressurise the outlet side by opening the sam-
pling valve (bleed valve on AQA therm HES).
3. Slacken the compression spring
- Use the adapter to get to the compression
spring. Turn the adapter to the left (-) as far as
it will go.
4. Slowly open the shut-off ball valve on the inlet side.
5. Turn the adapter until the pressure gauge reaches
the required value.
6. Re-tighten the slotted screw.
7. Slowly open the shut-off ball valve on the outlet side.
8.2 Setting AQA therm HES generation 2016
with electronical display with ‘smart’ set-up
and ‘smart’ operation
a) Remove the electronics housing, insert the battery
and replace the housing.
b) ‘Smart’ set-up:
The custom electronics of the AQA therm HES
generation 2016, with just 3 clicks, enable easy,
quick and intelligent setting of the operating
parameters, majoring on the preferred low-salt
process for natural, perfect heating water without
additives.
- no laborious searching in tables
- no fault-prone sensors
- all the attributes of modern smart metering
design and
- practical expansion options
„Smart”-operation:
Monitoring of the flushing, filling and refilling
volumes is available via the plain text display.
You can also use a ‘smart’ function to:
- turn the acoustic monitoring signal on/off
- register the relevant data
- send control signals to a solenoid valve
(available from Q4/2016)
- connect an SMS box – for sending alarm
messages to a mobile phone when cartridges
are depleted (available from Q4/2016).
c) The assigned selection fields in the display move
with each keystroke to the selected position. The
selection is logged if you pause on the position
for more than 3 seconds.
d) If the AQA therm HES operates without a cart-
ridge in the flushing process, select ‘NONE’,
and connect the flushing/dummy plug (Art.-no.
084154).
e) If the AQA therm HES is used for filling or refil-
ling, please insert the cartridge (see no. 8.7.).
Press the cartridge/cartridge button to toggle
between the different cartridges, pausing on the
selected cartridge for 3 seconds to log it.
f) The pre-defined hardness ranges for the ‘smart’ set-
up cover over 90% of the application areas. For
water hardness >26 °dH/46.3 °fH/463 ppm, the
maximum water hardness should be logged. An
estimate to the nearest litre can be seen using the
classic comparison method with the capacity tab-
le, ditto for the intermediate ranges (see cartridge
operation manual or no. 13).
g) If, according to the ‘smart’ set-up, cartridge ca-
pacity falls below 10%, the service LED will flash
yellow. When the cartridge is totally depleted, or
if the cartridge has been in use for longer than 5
years, the service display will flash red and emit
a beep. (Factory setting is tone on; to turn off, see
8.3 point h.)
h) Where necessary, use the ON/INFO button to
advance to turn the cartridge replacement sound
signal on or off, set the position required and
pause for 3 seconds to log the selection. Factory
setting: signal always on.
i) To reset the entire filling quantity in litres, please
press the ON/INFO button and the water Was-
serhärte/hardness button together for 3 seconds.
8.3 Flushing the system
Some national standards stipulate flushing the hea-
ting system, so a flushing/ dummy plug is necessa-
ry. This can be installed instead of the AQA therm
hardness-reducing cartridge (HRC) or desalination
cartridge (SRC). After flushing, reconnect the cart-
ridge to fill the system.
