Operation; Maintenance - Zehnder ComfoCool Q600 Manual Del Usuario

this purpose:
■ Where possible your selected temperature profi le
is maintained by opening the heat-recovery bypass
valve. Thereby guaranteeing continued ventilation
while ensuring tempered supply air. This process
usually runs at night.
You can check the current bypass state in the menu
STATUS under the option BYPASS STATE.
■ When the temperature can no longer be maintained
by opening the bypass valve, then the system begins
active air temperation by activating a refrigerant
circuit. This may be required on a hot, sunny
summer's day, or if there is a lot of sunlight in your
dwelling. The system tempers the temperature of the
supply air. Moreover, the system extracts moisture
from the air, adding to a pleasant indoor climate.
You can see when the active refrigerant circuit is
on when the following symbol
operating panel. The ComfoCool Q600 makes a noise
similar to a fridge.

4. Operation

Your ventilation system with air temperation is controlled
using the operating panel. Consult the operating panel
manual for more detailed information. The system's key
functions are:
■ The ventilation level. Select from the following
settings:
o Away (PRESET A). Only use this setting when
you plan to be away for an extended period. The
ComfoCool Q600 is always off when this setting is
selected.
o Preset 1 . This is the lowest setting. Use this
setting when there are fewer people than normal in
your home.
o Preset 2 . This is the normal setting. Use this
setting when the dwelling is being used normally.
o Preset 3 . This is the highest setting. Use this
setting when you require extra ventilation, e.g. when
cooking, showering or if you are entertaining. Also
use this setting when the dwelling needs to be
tempered.
o Temporary high level BOOST. When you use this
setting, the system will ventilate at level three for
a given period. The system will then return to the
previous setting. Use this setting when cooking or
showering.
■ The temperature profi le. Your ComfoCool Q600
equipped ventilation system tries continuously to
maintain the temperature of the return temperature of
the heat-recovery unit based on your set temperature
profi le. This temperature may have to be achieved
by the unit automatically opening the bypass valve
or activating the active air temperation. For more

appears on the
information, read section 3.
o The temperature profi le can be set by selecting
COOL, NORMAL or WARM in the menu TASK
MENU under the option TEMPERATURE PROFILE.
■ Your heat-recovery unit is fi tted with a system
that detects whether it is summer or winter. In the
summer, the active air temperation can be activated,
while this is not desirable under normal winter
conditions.
o Active air temperation can be deactivated. In
the menu TASK MENU you will see an option
COMFOCOOL that can be set to either OFF or
AUTO. Select "ComfoCool Q600 Off" if you do
not wish to use active air temperation, even if your
dwelling gets warmer than the required temperature
profi le.
Please make sure your ComfoCool Q600 ventilation
system is checked and cleaned by a installer once every
4 years. Note: Only a recognised cooling-technology
installer may disassemble and clean the ComfoCool
Q600.
Cleaning condensation drain
Your ventilation system is fi tted with siphons for the
condensation drain. When running, the ComfoCool
Q600 discharges no more than 2.5 litres of condensation
an hour. It is therefore important that the siphons and
especially the drain's waste-water connector are clean
and clear of blockages. Check your condensation drain
once a year.
Cleaning ventilation valves
Your ventilation system is fi tted with valves for air supply
and air exhaust. Exhaust valves are fi tted in the wall or
ceiling of the kitchen, bathroom and toilet. Supply valves
are fi tted in the wall or ceiling of the living room and the
bedrooms. If the valves become visibly dirty, then clean
them. Hold the valve on its outer edge and pull it with a
rotating movement entirely from the wall or ceiling. Clean
the valve with soap, then rinse it and dry it. Always
remount the valve in the wall or ceiling in the same way
you removed it. Take care not to swap the valves, and
try to avoid altering the valve settings.
Filters
Your heat-recovery unit is equipped with fi lters
that prevent the heat exchanger from becoming
contaminated with dust. It is very important that these
fi lters are cleaned or replaced occasionally. Consult the
heat-recovery unit manual for instructions.
