THE COMBINED METER FOR THE
COSMO CARTRIDGE
• Programmable limit
• Dissolved Minerals as TDS
• Conductivity in µS/cm
Minerals and salts in the cooling
and heating water circuits lead to
corrosion and deposits. COSMO-
OWH-FP500 filters the aggressive
substances from the water and all-
ows a low maintenance operation.
DATA
Operating pressure
max. 6 bar
Temperature
max. 60°C
Batteries
3 x AA-LR6 Mignon
DESCRIPTION
The measuring counter is battery-operated.
It measures the flow rate in l/min, the total
amount in litres, and the concentration of
dissolved minerals either in µS/cm (micro-
siemens) or TDS (Total Dissolved Solids).
In addition, a boundary value can be fixed
for the maximum mineral concentration
still tolerated in the purified water (outlet
of the device). The boundary value and the
counter reading can be reset.
CHANGING THE BATTERIES
Change the batteries when the battery
warning symbol appears or the display is
faint or blank. Undo the 4 screws on the
front and carefully open the device.
Change the batteries: 3 x AA- LR6 Mignon
Make sure that the seal ring of the
housing is correctly seated!

OPERATING THE MEASURING COUNTER
Warning signal for
boundary value
green = OK
red = STOP!
Boundary value
Recommended:
50 µS/cm or 33 TDS
Boundary value for
set warning
Reset: push 3 sec.
Choose between
Conductivity = µS/cm
THE KEYS
Switch between µS/cm and TDS
Both are used to measure the concen-
tration of dissolved minerals in the water.
The water hardness at the outlet of the
refill appliance can be calculated:
1°dH equals approx. 35 µS/cm.
Boundary value
Each time you touch this key, the boundary
value is raised by 6/7 TDS or by 10 µS/cm.
Holding down the key for 3 seconds resets
the boundary value to zero. Programming
the boundary value serves as a warning
as to when the ion exchanger resin is
exhausted.
ON/OFF
Auto-Modus (1 x touch). The combined
meter begins automatic monitoring.
The eye symbol appears to indicate that
monitoring has been enabled. In auto
mode, the meter only takes measurements
when water is actually passing over it.
If the water draw-off is interrupted, the
meter continues to show the last captured
value. While water is beeing drawn off,
the combined meter measures the
water quality every 10 litres. If the limit
is exceeded in two successive measure-
ments, the display continuously flashes
red. This indicates that the ion exchange
resin is spent and needs replacing.
TDS = ppm
Volume flow measurement (2 x touch)
Measurement of water flow. Mineral
content measurement is not active.
Measurement, short (3 x touch)
The water quality is measured for 10 sec.
and compared to the set limit. The
measured value is shown. If it is above the
limit, the LED glows red; if it is below, the
LED glows green while the measurement is
being taken. If required, the measurement
can be repeated manually.
Off
Press and hold the ON / OFF button for
5 seconds to turn off the meter.
Total flow (Total l)
Press and hold for 3 seconds to reset the
value to 0.
Subject to change.
