SAFETY
General information Electrical safety
Always check that the supply voltage to the
equipment is switched off before opening the
service hatch.
Only an authorised electrician may open the
electrical box.
Follow the local regulations on electrical
installations.
In case of a malfunction, always determine the
reason for the malfunction before restarting the
unit.
When you have switched off the power to the
unit, wait for two (2) minutes before starting the
maintenance work. Even though the power is
switched off, the fans continue running and the
post-heating coil remains hot for a while.
Check that the unit is completely isolated from
the mains supply before conducting any voltage
tests, insulation resistance measurements or other
electrical work or measurements. Such work may
damage the sensitive electrical equipment.
Control equipment used in the ventilation units
may cause leakage current. This may affect the
operation of the residual current protection.
All ventilation units containing a control system
must be equipped with an overvoltage protector.

BEFORE INSTALLATION
Choosing the installation location
• Ensure that the ventilation system has been designed
and realised in accordance with the building
regulations.
• We recommend that the unit be installed in the
technical facility.
• Do not install the unit in a room where the
temperature and humidity are high. Under certain
conditions, condensation may occur on the outer
surface of the unit.
• Take the noise level of the unit into account when
choosing the installation location.
• Install the unit on a soundproof wall, if possible.
• Do not install the ventilation unit directly outside
the bedroom, as the unit is never completely silent,
although it is quiet.
• Install an insulation plate behind the ventilation unit,
or try to prevent the sound from being conducted to
the structure by other means. Using soft foam sheets
is recommended (not included in the delivery).
• Ensure that connecting the condensation water
discharge pipe and water trap is possible. Remember
to take the space required by the condensation water
connection into account.
• Install the unit in a warm room (over +5°C).
• Ensure that at least 500 mm of free space is left in
front of and at least 80 mm of free space is left below
the unit for maintenance purposes.
If you would like to know more about the
construction of ventilation systems and the
insulation of ventilation ducts, you can read about
them on our website at www.enervent.com.

Do not connect an external bus to the
motherboard before the bus has been
programmed and is compatible with the control
of the unit.
CAUTION
Installation to the Modbus bus
The ventilation unit can also be controlled via the Modbus
connector X26.
Modbus specification:
• Modbus address 1 (default)
• Data transmission protocol RS485
• Modbus traffic via the motherboard’s Modbus
connector X26
• Speed 9,600, 19,200 or 115,200 bps
• 8-bit
• No parity or parity
The order of the poles in the Freeway connector is marked
in the controller board.
The Modbus registers are available on the Enervent
website at www.enervent.com.

COMMISSIONING
Requirements
Operational requirements for the ventilation unit:
• Supply and exhaust air temperature below +55°C.
• Exhaust air temperature at least +10°C
• Supply air temperature for heat recovery over +5°C
• Supply air temperature over +10°C
• All foreign objects have been removed from the
ventilation system
• Both fans are running
Air flow adjustment
When the unit has been switched on, the air flows must
be adjusted to the designed values.
• The air flows are adjusted in connection with the
commissioning of the ventilation unit.
• The adjustment is made separately for both fans in
each operation mode (= at each fan speed).
Check the following during the adjustment:
• All filters are clean.
• All supply and extract air vents, the roof inlet, and the
outdoor air grilles are in place.
To achieve optimum adjustment values, the air flows
must be measured at each duct opening. A suitable
measurement device is a thermoanemometer or
a differential pressure gauge. With the aid of the
measurement values, the air flow can be adjusted to
match the design values.
A correctly adjusted ventilation unit is quiet and provides
a good thermal economy. In addition, it also maintains
a slight negative pressure in the house. The negative
pressure prevents humidity from entering the walls and
ceiling.
Measure Inspected Notes
The unit has been installed in accordance with the installation
instructions provided by the manufacturer.
The condensation water discharge pipe has been connected to
the water trap, and its operation has been tested.
Silencers have been installed in the supply and extract air ducts.
The terminal devices have been connected to the ductwork.
An outdoor air grille has been installed for the intake of fresh air.
NOTE: Do not cover the grille with a mosquito net. It makes
cleaning difficult.
The unit has been connected to an appropriate power supply.
The ventilation ducts have been insulated in accordance with the
ventilation plan.
The airflows are adjusted according to the ventilation plan.
Commissioning checklist
Do not cover the outdoor air grille with a
mosquito net.

Important information about the control
system
The factory settings are suitable for most installations.
The fan speed settings for various operating modes are
installation specific, and they must be specified and set
separately in connection with each installation. In other
cases, the factory setting must not be changed unless
otherwise instructed in the ventilation system plan.
Make sure that all necessary information is available before
starting to adjust the settings.

The fan speed settings for different operation modes must
be specified and set separately in connection with each
installation. The settings are described in the parameter
table.
