1. Casing
Inside is the unit made of EPP (Expanded
PolyPropylene). The outside casing is made of
galvanised sheet metal with 30mm insulation. As a
standard, the side panels and the front are white
(powder paint). The front door has a magnetic strip
which keeps the door closed. The unit top has
sleeve connections made of EPP, where all ducts
are connected.
2. Exhaust air filter
G4, bag (art. No. G10125)
3. By-pass damper
The Temovex AHU has an automatic by-pass
damper which makes the air by-pass the heat
exchanger whenever heat recovery is not
necessary. The by-pass setting is adjusted on the
control panel.
4. Exhaust air fan
The unit has low-energy fan of EC type with
integrated overheating.
5. Supply air fan
The same type as exhaust air fan (see point 4).
6. Heat exchanger
The heat exchanger is a standard highly efficient
counterflow heat exchanger from Recair. The heat
exchanger is made of very thinny, pleated plastic
sheets and and the supply air and exhaust air sides
are completely sealed from each other. This is
important in order to avoid odours and other
contaminants from old air seeping through to fresh
air. The heat exchanger has no moving parts, which
eliminates wear.
7. Supply air filter
F7, bag (art. No. G10126)
8. Elevator device
The elevator device must unfasten to make it
possible to take out the heat exchanger for cleaning.
(See chapter "Maintenance & service").
9. Adjustable feet
The cabinet has adjustable rubber feet.
10. Condensate drain
The Temovex unit is fitted with a condensate drain
at the bottom of the unit. This should be connected
to a drain or fed to a floor drain.
11. Control panel
All settings for fan speed, after-heating, by-pass etc.
are made via the control panel and the AHU's
integrated control system.
If you have added optional parts to your Temovex
AHU, these functions, too, are set via the control
panel.
12. After-heater
Temovex Blue 4 is fitted with an electric afterheater, 0.9 kW.
As an optional extra, a reinforced electric afterheater, 1,8 kW, or a water coil (two different sizes)
for waterborne heating is offered. The heater is
integrated in the unit and settings are made via the
control panel.
In the case of a water coil, the water connections
are at the top of the unit, dimension DN12.
The Temovex Blue 4 with water coil includes a twoway valve and valve motor in the consignment from
REC.

1. Temperature.
Temperature
The outdoor temperature is measured on incoming air close to the AHU. The temperature can differ a little from
the real outdoor temperature, depending on the duct length, insulation etc.
The supply air temperature is measured in the supply air duct, normally about one meter from the AHU. Supply air
is the fresh air that - after possible heating - is sent into the room.
The exhaust air temperature is measured close to the AHU. Exhaust air is the air that leaves the room and goes
back to the AHU, where the heat is recovered.
The extract air temperature is measured close to the AHU. Extract air leaves the AHU and is sent out from the
house.
The room temperature is measured with an external sensor, placed in an appropriate place in the flat/house.
The freeze protection temperature is only used with water heating and shows the temperature of the return water
from the heater. To prevent freezing of the water heater, the AHU will stop if the water temperature is too low.
ECO adjust.
ECO adjust. is only used with exhaust air control and room control, and gives a temperature range where heating
and cooling is disabled.
Example: ECO-adjust 2 degrees and a set temp at 20 degrees means heating and cooling will be disabled
between 18 and 22 degrees. ECO-adjust is activated when ECO is enabled.
Control function
What is shown in the temperature menu depends on the selected control function. There are four control functions
to choose between, depending on application: a) supply air control, b) cascade exhaust air control, c) cascade
room control and d) outdoor compensated supply air control.
For temperature settings and reading, choose the column that corresponds to your configuration.
a) Supply air control b) Exhaust air control c) Room control d) Outdoor compensated supply air
control
* The menu Freeze P temp. is only shown if water heater is configured.

Fan control
Five modes are always available:
· Auto: gives you an optimized function. The temperature is automatically controlled in accordance with
the unit's internal and optimized algorithms.
· Min. flow: The system is forced to use a set minimum air flow.
· Boost flow: The system is forced to boost the air flow. Useful for example if you need to air the building
very fast.
· Max. flow: The system works at set maximum air flow.
· Off: All fans are switched off.
Four other modes are available if those functions are installed and configured. (It is possible to choose these
modes even if the function is not configured, but the system will return to earlier choice after a few seconds.
· Stove: This mode should be used when the stove/fireplace is used. The supply air fan works at a higher
speed than the exhaust air fan, to compensate for the air the stove extracts. The cooling is disabled for a
while after the stove/fireplace has been used, in order to retain the good stove heat.
· Kitchen: Use this mode when the cooker fan is running. The supply air fan works at a higher speed than
the exhaust air fan, to compensate for the air the cooker fan extracts.
· ECO: Suitable to use when no one is at home. The fans switch to minimum flow, but gradually
increase to normal flow when there is need for higher or lower temperature. ECO-adjust gives a
temperature range around the setpoint and neither heat nor cool is enabled.
· Fire: To be used above all when testing the fire function. The supply air fan stops at the same time as
the exhaust air fan works at its maximum speed.
Timer settings
The clock and summer/winter time
The clock can be set and the change between summer and winter time can be made automatic.
Enable timer
The timer is enabled upon delivery and connected to the function Min flow. If the timer is disabled, so are preset
times and holiday schedules.
Time schedule
Two periods a day may be set. Note! To enable the timer from, for example Monday 20:00 until Tuesday 06:00
the settings should be Monday Per 2: 20:00 – 24:00 and Tuesday Per 1: 00:00 – 06:00.
To repeat the same time every day of the week, use the function Monday Ú Friday.
If you want the same time on Saturdays, Sundays and all holidays (specified in holiday settings), use the macro
function Saturday Ú Holiday.
There is a separate menu for holiday schedules.
Holiday schedule
Up to 24 separate holiday periods for a complete year may be programmed. A holiday period may consist of a
succession of days, from 1 to 365. The date is written: MM:DD. (It is important to set the time period from 00:00
one day until 00:00 next day. For example holiday June 6 will be written 06:06 – 06:07.) If that particular day falls
during a holiday period, the system will use the schedule for “Holiday”.

Manual/Auto
In Manual/Auto it is possible to control a number of functions manually, which
is very useful during the start-up process and for troubleshooting.
Available menus are shown here. All functions cannot be configured at the
same time as there are not enough outputs available. Furthermore, some
functions are not needed in the application.
If an output is controlled manually, it means that the normal regulation is out
of order. Therefore, an alarm will be generated as soon an output is changed
to anything else than Auto.
Supply air controller
The output from the supply air controller may be adjusted manually between
0-100%. The output from the temperature controller will follow if it is in Auto
mode.
Fans, By-pass damper, Heat and Cool.
The output to the fans, heater, by-pass damper and cooling may be adjusted
manually between 0-100%. The actual position of the by-pass damper is
displayed in the menu.
Digital outputs
All configured digital output signals, such as ULS, KAVK, CP etc, can be
assigned Auto, On or Off (or a similar word that indicates the two possible
levels of a digital signal).
Filter timer
The filter timer is administered here. The interval between the filter changes
may be set from 6 to 18 months. The menu displays how many months
remain before the filters must be changed. NOTE! This value is updated only
ones a day. This means that if ”Interval” is changed, ”Remains” will not be
updated before next day.
Do not forget to reset the timer when the filters are changed (even if the
filters are changed earlier than expected).

5. Alarm
All current alarms and the status can be seen by pressing the red button.
In this menu alarms can be acknowledged, blocked or unblocked (allow alarm).
There are 2 types of alarms: A and C alarms. A-alarms do not disappear until they have been fixed and
acknowledged. C-alarms are internal alarms and will disappear automatically as soon as the alarm reason has
disappeared.
Some faults cause immediate stop of the unit, as continued operation would be dangerous.
An acknowledged alarm that has not yet been dealt with remains on the menu as Acknowledged. It disappears
from the menu when the fault has been dealt with.
It is possible to block an alarm and continue to run the unit. Note! Do not do this unless you really know what you
are doing, since it could be dangerous and in worst case damage both unit and property.
Alarm history
The last 21 alarms are displayed. You can see when the alarm went off, when it was acknowledged and/or
returned and so on. In this menu, it is not possible to acknowledge or block any alarms.

Cleaning
For best possible performance and a long life, the
AHU should be kept clean. Please see instructions
below on how to clean fans and heat exchanger.
Changing filters
There are two filters in this AHU: exhaust air filter
and supply air filter (fresh air).
Both filters should be changed at least once a year,
and more often if need be. Do not wash the filters,
but exchange them for new ones.
To buy new filters, please contact the local dealer in
your country or order from www.rec-indovent.se
NOTE! The Temovex AHU must be fitted
with the Temovex filters listed on page 1 of this
manual. If the unit operates without filters, the
performance will be affected adversely and fans and
heat exchanger may be seriously damaged.
· Cut off the power.
· Open the unit door.
· Remove Cover plate.
· Remove EPP spacer by
pulling straight out.
· Remove the old outdoor air
filter.
· Release the inner cover by
turn the two hooks. Remove
the cover. (Behind the cover
is the exhaust air filter).
· Remove the old exhaust air
filter.
· Clean accessible surfaces if necessary.
· Fit the new filters and cover in reverse order.
(The shortest filter first).
· Close the unit door.
· Turn on the power.
The unit operates even if the filters are dirty, but the
performance would be less good; energy
consumption increases and heat recovery
decreases.
To turn off/aknowledge filter alarm, see Ch 5.
Cleaning the fans
.
· Cut off the power.
· Open the unit door.
· Remove both upper and lower cover.
· Unfasten the elevator
device at the bottom of
the front side of the unit,
so that the heat
exchanger package is
released from the topunit.
Loosen until it can not
rotate more.
· Pull out the whole exchanger package.
· Unconnect the fan cables from
the PC board.
· The fan package is now standing
on rails at both sides. Pull out the
entire fan package.
· Loosen respectively fan holder
and take out holder inkluding fan
from the EPP package.
· Clean the impeller using a brush or
compressed air.
· Clean accessible surfaces and ducts in the
EPP package if necessary.
· Refit the fans in the fan package.
· Refit the fan package on the rails.
· Refit the exchanger package in the unit.
· Tighten the elevator device and be careful that
the grooves in the different EPP units will fit
each other. Tighten until the grooves are
completely together.
· Reconect the fan cables.
· Refit the covers.
· Close the unit door.
· Turn on the power.
NOTE! The fans must under no
circumstances be cleaned under running
water!.
Cleaning the heat exchanger
· Cut off the power.
· Open the unit door.

Checking the condensate drain
· Open the unit door.
· Remove the
condens hose and
make sure the hose
is not blocked. Even
make sure that the
hose connection to
the unit not is clogged.
· If the drain is clogged, try to remove the
obstruction.If need be, call a plumber.
· Reconnect the hose.
· Close the unit door.
Cleaning the air diffusers
The building's air diffusers must be
cleaned regularly in order to maintain
correct ventilation. Use a dry cloth
and/or a small brush to reach inside the
opening of the diffuser. It can also be
taken down if that makes cleaning
easier. Use a duster or a dry cloth to
remove possible dirt marks in the ceiling
around the device.
NOTE! The air diffuser's setting must not be
changed. If taken down, each diffuser must be
returned to its original place.
Cleaning the duct system
The exhaust air
ducts - and
sometimes the
supply air ducts as
well - may need
cleaning at long
intervals. Dust and
dirt will deteriorate
the capacity of the
AHU if not removed.
Authorized ventilation cleaners should carry out the
cleaning. However, you yourself can easily clean
the part of the duct which is close to the air
diffusers.
Take down the diffuser. Use a vacuum cleaner or
duster to clean the inner part of the duct as far as
you can reach. Refit the diffuser, making sure the
setting is not changed.
Checking the outdoor air intake
Once a year the outdoor air intake should be
checked. Make sure it is not clogged by for
example leaves, snow or ice.
Service
Service and repairs, beyond normal maintenance,
should be carried out by professionals in the
ventilation field, or - if electricity is involved - by an
authorized electrician.
The electric panel must not be opened by
other than authorized specialist.
Interferance with the AHU system may affect
the warranty terms.
Use original spare parts only.
Disposal
Prevent accidents when the AHU is disposed of.
Remove the cable from the wall socket and cut it as
close to the unit as possible. Store and transport
the waste unit lying down.
Please leave the unit to be recycled where such
facilities exist. Check with your local authority for
recycling advice.
