FOREWORD
All Enervent ventilation units are designed and manufactured for use all year round. In Finland the ventilation units have
been installed in houses and other spaces for over 20 years and their popularity is increasing each year. Because of the
knowledge and experience we have amassed during these years, we can now manufacture more energy ecient and user
friendly ventilation units. The Enervent unit series is the result of a long product development. All units in the series are
very versatile and exible.

OPERATING PRINCIPLE
The ventilation units are based on a regenerative heat recovery This is achieved with a rotating heat exchanger through
which incoming air and extract air ow in opposite direction. Aluminium foils within the heat exchanger transfer heat
from the extract air to the supply air. A characteristic of the regenerative heat exchanger is its high rate of heat recovery
(or eciency).
The eciency varies from 75% to 85%, depending on the proportion of supply air and extract air (the heat from the supply
air fan is taken into account). Thanks to their high eciency, the units save heating energy at the same time as they provide
excellent indoor air quality; therefore they pay themselves back in a relatively short time.

OVERVIEW
DUCT HEAT INSULATION
Ventilation ducts must be thermally insulated to prevent water from condensing to the inner or external duct surfaces in any
circumstances. Additionally, the air temperature must not decrease or increase excessively in the ducts because of external fac-
tors. The ventilation engineer calculates the insulation requirements depending on the placement of the ducts and the air temperatu-
res.When the insulation materials are designed, it must be taken into account that the extract air temperature may decrease signicantly
belowzerodegrees.TheOptimizersoftware,whichisavailablefromEnstoEnervent’swebsite,canbeusedtocalculatetheextractair
temperature with dierent outside air temperatures. Calculation software available from insulation material manufacturers can also be
used when designing the insulation material thickness.
Table 1: Ventilation duct thermal insulation in heating use
Supply air duct from the ventilation unit to the
supply valve
The insulation must be designed and implemented so that the
maximum air temperature change in the duct is less than 1°C.
Extract air duct from the supply valve to the venti-
lation unit
The insulation must be designed and implemented so that the
maximum air temperature change in the duct is less than 1°C.
Table 2: Ventilation duct thermal insulation in cooling use
Supply air duct from the ventilation unit to the
supply valve
The insulation must be designed and implemented so that the
maximum air temperature change in the duct is less than 1°C. At
least 18 mm of cellular rubber insulation on the duct surface and
sucient additional insulation.
Extract air duct from the supply valve to the venti-
lation unit
The insulation must be designed and implemented so that the
maximum air temperature change in the duct is less than 1°C.
Ventilation Duct Insulation Examples:
Outside air duct (fresh air duct)
Cold spaces: 100 mm of sheet, mat, or pipe-covering insulation (plus the blown wool, when used).
Warm/semi-warm spaces*:
Option 1: 80 mm insulation with vapour-proof external surface
Option 2: 20 mm of cellular rubber insulation on the duct surface and 50 mm insulation with vapour-proof external surface.
The insulation must prevent water vapour from condensing to the external duct surface and excessive air temperature rise during sum-
mer.
Supply air duct
Cold/semi-warm spaces*:
In standard ventilation the insulation must be designed and implemented so that the maximum air temperature change in the duct is
less than 1°C. For example, 100 mm of sheet, mat, or pipe-covering insulation can be used (plus the blown wool, when used).
Warm spaces: Insulation is not required in standard ventilation.
In heating and cooling use see tables 1 and 2.
Extract air duct
Warm spaces: Insulation is not required in standard ventilation.
Cold/semi-warm spaces*:
In standard ventilation the insulation must be designed and implemented so that the maximum air temperature change in the duct is
less than 1°C. For example, 100 mm of sheet, mat, or pipe-covering insulation can be used (plus the blown wool, when used).
In heating and cooling use see tables 1 and 2.
Exhaust air duct
Cold spaces: 100 mm of sheet, mat, or pipe-covering insulation
Warm/semi-warm spaces:
Option 1: 80 mm insulation with vapour-proof external surface
Option 2: 20 mm of cellular rubber insulation on the duct surface and 50 mm insulation with vapour-proof external surface.
The insulation must prevent water vapour from condensing to the external and internal duct surfaces.
Circulation air duct
The insulation must be designed and implemented so that the maximum air temperature change in the duct is less than 1°C.**
*) A semi-warm space refers also to dropped ceilings, sub-oors, and casings.
**) When Kotilämpö systems are renewed, the recycling air duct can be left as it is.
Sound insulation is not taken into account in these insulation instructions and examples.

be preerd to an exterior wall for the units installed on a wall.
The LTR-2, LTR-3, LTR-6 and LTR-7 units can be installed in either a warm or cold space. The unit must be equipped with 100
mm extra insulation, if it is installed in a cold space. Suitable places for installation are for instance store rooms or the attic.
The unit should be placed on a plain surface on an elastic material that absorbs sound. For example, a 100 mm thick insula-
tion plate is suitable as bedding
If the unit is used to ventilate an area with a swimming pool, the unit must be drained. For more information see the drai-
nage instruction on the next spread.
PHASES OF INSTALLATION:
N.B.! To reduce the weight of the unit you can remove the heat recovery wheel before mounting the unit.
Plaza, Pingvin Pingvin XL and Pandion on the wall
1. Mark and cut the holes into the ceiling.
2. Draw the ducts through the holes to the required height. The gaps between duct and steam barrier are then
sealed, with for instance ventilation tape.
3. Place a piece of insulation material behind the unit to reduce the transfer of machine noise or vibration. We re-
commend that soft cellular plastic is used (not included in delivery). The unit surface should be equipped
with extra insulation (i.e. cellular plastic) if the unit is placed with one side towards an exterior wall or there is risk
that condense might develop on the exterior of the unit.
4. Pingvin and Pandion units: Install the rear attachment bracket directly to the wall at required height. Place the
unit onto the rear bracket and fasten it to the wall with the two top brackets. Attach the rear bracket with plate
screws to the bottom of the unit. It is crucial for Pingvin unit drainige that the unit is slightly tilted back .
Plaza: Place the unit on the wall and fasten it to the wall with the two top brackets.
4. Connect the unit to the ductsystem. It is recommended that silencers be installed to the extract and supply air
ducts.
5. Drain the unit. Read the drainage instruction.

Enervent EDA MD EN 2013_1
INSTALLATION
Pandion on the oor, Pelican and Pegasos
1. Install the unit on the oor or on a level built for the unit so that it stands on its own rubber pads. Leave at least
a 10 mm opening between the back of the unit and the wall and at least a 15 mm opening to the sides. Also
take into account the space needed for drainage below the unit.
2. Make sure that there is at least 95 cm of free space in front of the unit’s maintenance hatch and remember to
leave the electric wirings easily accessible. The unit has a connecting plug. The connecting cable is located in
the front corner above the smaller door. The length of the cable is 120 cm.
3. Connect the ducts to the unit with exible connectors. Silencers are recommended for the supply air and
extract air ducts.
4. Drain the unit. Read the drainage instruction.
LTR-2, LTR-3, LTR-6 and LTR-7
1. Place the unit on the insulation plate (i.e. 100 mm insulation covered with chipboard) in a storage room or in
the attic on a custom made shelf. Take into consideration the potential need for a drain.
2. Check that there is enough free space on top (above the service hatch) (LTR-2 and LTR-3 min. 50 cm, LTR-6 min
60 cm, LTR-7 min. 70 cm) and that the electrical inlets are accessible. Take into consideration that opening the
hatches requires a certain amount of space.
3. Connect the ducts to the spigots on the unit. It is recommended that silencers be installed to the extract and
supply air ducts.
4. Drain the unit. Read the drainage instruction.
N.B! Detailed dimension drawings can be found in the Chapter Technical information at the end of this manual.
Installation of duct coil
Some of the models have the after heating/cooling water coils in the duct. The duct coil is placed in the supply air duct
after the ventilation unit. The supply air temperature sensor is placed in the duct after the coil. The water coil return water
sensor is placed on the return water pipe of the coil. VEAB CWK duct coolers are manufactured only in one handedness.
Make sure the service hatch can be opened at need.The air ow direction is marked on the coil.The coil must not be turned
the oposite way, becuse the condense water drain will not work properly. Tilt the coil a little towards the condens water
drain to ensure eective draining.

INSTALALTION
DRAINING THE VENTILATION UNIT
All Enervent-units with cooling must be drained. We recommend that also other units are drained. When air cools down
(condenses) condense water forms i.e. in winter time when the humid inside air meets the cold heat recovery wheel or
if the unit is equipped with cooling. The condense water drain must not be directly connected to a sewer! The condense
water should be led in a falling, at least Ø15 mm pipe, through a water lock to a oor drain or such. The pipe must at all
timeslielowerthanthebottomoftheventilationunit.Theremustnotbeanylongerhorizontalsectionsonthepipeand
there mustn’t be more than one water lock. If the unit is equipped with more than one condense water draines, each one
must have a water lock of its own.
There is under pressure in the ventilation unit. We recommend a hight dierence of (A) 75 mm, or at least the under pres-
sure divided with 10 in millimeters (i.e. 500 Pa under pressure -> 50 mm), between the unit drain and the water lock drain.
We recommend that the hight of backwater in the water lock (B) is 50 mm, or at least the under pressure divided with
20 in millimeters (i.e. 500 Pa under pressure -> 25 mm hight of backwater). Over pressure is prevailing in a duct coil. We
recommend the hight dierence (A) between the duct coil drain and the water lock drain is 25 mm. The water lock hight
of backwater (B) must be 75 mm, or at least the under pressure divided wit 10 in millimeters (i.e. 500 Pa under pressure ->
50 mm). The water lock must be lled with water before starting up the unit. The water lock might dry up if water is not
accumulated in it. If this happens, ait might get into the pipe and hinder water from entering the water lock, which might
result in an irritating ”bubbling” sound.

STARTING THE UNIT
Before the unit is ready for use the following installations should take place:
- Assemble the unit as stated in the chapter Installation in this manual.
- Connect the drainage outlet with its own hose to an outow supplied with a water lock (if the unit ventilates a
space with swimming pool or if it is equipped with cooling).
- Install the duct and the silencers.
- EDW model coil, valve, valve actuator, return water temperature sensor and supply air duct sensor are installed
and connected.
- Water circulation of the EDW model coil is connected.
- Assemble the terminals onto the ducts.
- Provide the outside air duct with an outside air grating. N.B! the grating must not be provided with an insect net
because it is dicult to keep clean.
- Make the roof pass-through. We recommend the use of a factory made, insulated roof pass-through.
- Insulate the ducts as instructed.
- Provide the unit with the appropriate power supply.
- Connect the control panel to the unit with the RJ4P4C cable provided (to the connector OP1 of mother board).
The unit’s mother board is in the electrical connection box. In vertical units the connection box is behind the
 smallerdoorunderacoverplatefastenedwithscrews.Inhorizontalunitstheconnectionboxisundertheser-
vice hatch in the upper part of the unit.
- Program the external bus. NOTE! The programming must be nished before the RJ45-bus connector is con-
nected to the mother board.
- Fill out the warranty and all possible changes in the parameter list (eld settings) at the end of this instruction.
Open the unit’s maintenance hatch when all the above mentioned installation work is done. Check that the unit is clean
on the inside, that there are no extra articles inside the unit and that the lters are clean. Close the maintenance hatch
carefully.
NB! The device is not to be started or used when the hatch is open!
SUPPLY AND EXTRACT AIR CALIBRATION
After the unit has been switched on its airows must be calibrated to its planned values. When making the calibration all
lters should be clean, all supply and extract air valves, the roof pass-through and the outside air grating should be in place.
The outside air grating must not be provided with an insect net. The extract air ow should be ca. 5 - 10 % higher than
the supply air ow. To achieve optimal values during calibration the airows should be measured at each duct opening.
A suitable measuring instrument would be a thermo anemometer. With the help of registered values the airow can be
regulated to achieve the projected values. A correctly calibrated ventilation unit is quiet and gives a good heat return and
it also upholds a small under-pressure in the house. The under-pressure stops humidity from entering the walls and ceiling.
OVERVIEW ON VENTILATION
The ventilation unit should never be switched o. Always keep the ventilation at suitable power! If the ventilation is insuf-
cient, the humidity indoors becomes too high and can result in the formation of condensation on cold window surfaces.
A relative humidity of 40 - 45 % indoors is recommended (room temperature of 20 - 22°C). At these levels condensation will
not form and the humidity will be at a healthy level. Check the indoors humidity levels regularly. This can be done with a
hygrometer. When the humidity rises above 45 % one should increase the ventilation and when the humidity goes lower
than 40 % one should lower the ventilation. Check regularly that the lters are not dirty! During winter the extract air lter
becomes dirtier more quickly than the supply air lter. As a result of this the airow lessens, which leads to a lower humidity
indoors. This also leads to lower temperatures. Check the lters each month! At each lter inspection, check that the heat
exchanger is functioning correctly, meaning that it is rotating. Cover both the outside air intake and the exhaust air outtake
if the unit is not to be used for a longer period. This way you stop moisture from condensing on e.g. the fans’electric motors.

ALARM
All alarm and service messages are visible in the unit’s Alarm menu. 20 alarms are shown in the list. An alarm can have one
of the following three statuses; ON, RES reset, but still active or OFF.
The alarms are divided into three classes, class A, class AB and class B. Class A alarms shut down the unit. Class AB-alarms set
the unit in failsafe mode. In failsafe mode the extract air fan runs on smallest eciency and the supply air fan stands still1.
Class B alarms do not aect the unit’s function. An alarm symbol is ashing in the display when class A and class AB alarms
are active. The light is not shown at class B alarms.
The unit doesn’t start before a class A alarm has been reset. Class AB-alarms reset automatically and the unit automatically
starts when the alarm no longer is valid.
For example TE30 min. alarm: If the extract air temperature has dropped below the set value for more than 10 min an alarm
i activated (ON) and the units goes into failsafe mode (AB-alarm). If the alarm is reset the alarm changes to RES mode, but
the failsafe situation continues. The unit does not start before the temperature rises over the set value and the alarm goes
into OFF mode.
There are two relay outputs for alarms on the EDA motherboard: ALM A and ALM B. Output ALM A conducts when a class
A alarm is active. Output ALM B conducts when an A- or AB-alarm is active and the time is within the alarm B output vali-
dity. The alarm B output can conduct weekdays between 9 am and 10 pm.
1 In passive house models also the extract air fan stops.

If the end time for the time program is smaller than the start time,
the control interprets that the time program continues over the
day limit. In this case the next day also needs to be an allowed day. Example: Start: 16:00, End: 08:00, Allowed days: Mo, Tu,
We. This time programming means that the program start on Monday at 16:00, ends on Tuesday at 08:00, starts again on
Tuesday at 16:00 and ends on Wednesday at 08:00. After that the program is active again next Monday at 16:00.

Time program events:
Ventilation eect (1-8) for ventilation units with alternating current fans. The number of available ventilation eects
depend on the fan eect’s initial settings. If the speed of the supply air and extract air fan is the same, the number of avai-
lable eects are 8. If the dierence in speed is of 1, then the available number of eects are 7, if the dierence is of 3, then
the number is 5 etc.
Ventilation eect (20-100%) for ventilation units with eco direct current fans. The maximum available ventilation ef-
fect depends on the fan eect’s initial settings. If the speed of the supply air and extract air fan is the same, the maximum
eect available is 100%. If the dierence in speed is 10% then the available eect is 90% etc.
Away: The unit is set to the Away state.
Long away: The unit is set to the Long away state.
Max heat: Maximum heat is turned on. Event continues until the timer runs out or the limit value is reached.
Max cooling: Maximum cooling is turned on. Functions in the same way as max heat.
No heating: heating prohibited.
No cooling: Cooling prohibited.
Temp. drop: The temperatures set point is lowered according to the amount set in settings.

The dierence in speed between the supply air and extract air fan
is set in the normal speed menu. The set values do not dene
the fan speeds, just the dierence between them. The set values
aect the fan speed columns in the EDA control panel basic view
- the number of columns decline with the quantity of dierence.
For more information see the chapter about display symbols on
page 10.
The fan speed, during overpressure, is selected so that there is
enough natural draft in the chimney while lighting a re in the
replace. 10 – 15 minutes is usually enough.
