Unplug unit from mains before opening the door (disconnect the power plug from the outlet or if there is a two-pole automatic circuit breaker
installed – disconnect it as well. It is necessary to ensure that it won’t be turned on by third parties) and wait until the full stop of the fans
(for about 2 min.).
Dirt increases air resistance in the lter, therefore less air is sup-
plied into the premises.
It is recommended to change the lters every 3-4 months,
or in accordance to lter timer.
Reset the lter timer in control panel after change of the
lters.
Taking off the lters:
• Open cover.
• Remove the lter.
• Use lters of M5 class.
CAUTION: the heat exchanger can not be used when the
lters are removed!
• Maintenance should be performed only by experienced and trained staff.
• The fan should be inspected and cleaned at least once a year.
• Be sure the fan is disconnected from power source before performing any maintenance or repair.
• Proceed to maintenance and repair after any rotation in the fan is stopped.
• Observe staff safety regulations during maintenance and repair.
• The motor is of heavy duty ball bearing construction. The motor is completely sealed and requires no lubrication for the life of the motor.
• Detach fan from the unit.
• Impeller should be specially checked for buil-up material or dirt which may cause an imbalance. Excessive imbalance can lead to accelerated wear
on motor bearings and noise, vibration.
• Clean impeller and inner housing with mild detergent, water and damp, soft cloth.
• Do not use high pressure cleaner, abrasives, sharp instruments or caustic solvents that may scratch or damage housing and impeller.
• Do not plunge the motor into any uid while cleaning impeller.
• Make sure, that impeller’s balance weights are not moved.
• Make sure the impeller is not hindered.
• Mount the fan back into the unit. Connect the fan to power supply source.
• If after maintenance the fan does not start or stop itself, contact the producer. Malfunction of the fan can be identied according to the pressure in the
system (when pressure switches are connected). When there is a fault in fans’ motor, any separate notice is shown on the control panel.

• When connecting air ducts, consider the notices indicated on the casing of the unit.
• Before connecting to the air duct system, the connection openings of ventilation unit should be closed.
• Do not connect the bends close to connection anges of the unit. The minimum distance of the straight air duct between the unit and the rst branch of
the air duct in the supply air duct must be 1xD, in air exhaust duct 3xD, where D is diameter of the air duct.
• It is recommended to use the accessories-holders. This will reduce vibration transmitted by the unit to the air duct system and environment.
• Enough space must be left for opening of the maintenance door and lter covers.
• If the installed ventilation unit is adherent to the wall, it may transmit noise vibrations to the premises. Though the level of noise caused by the fans is
admissible, it is recommended to mount the unit at the distance of 400 mm from the nearest wall. If it is not possible, the mounting of the unit is recom-
mended on the wall of the room where the level of noise is not important.
• Ducts are connected to the unit in such way that they could be easily disassembled and the heater could be removed from the unit when performing
service or repair works.

Information for the user about active functions, alarms or warnings. Meaning of the indications:
System mode is activated from the external contact
Fans speed is activated form the external contact
Reduction of fans speed according the temperature
Reduction of CO2 level
Active circulation pumps maintenance check up
Heating season (winter)
Cooling season (summer)

Automatic operation of the system is blocked. This function
is activated during service maintenance.
Active holiday schedule. To change the mode it is neces-
sary to stop the function or change the holiday date.
These functions (in sequence as set out) change the modes of the system:
1. blocking of Stand-by mode stand-by mode can be blocked under preferable parameters.
2. holiday schedule user cannot change the mode. System informs about active mode of the holiday schedule. To
stop the function it is necessary to change or disable the period of the holiday;
3. user‘s manual mode selection user can change the modes;
4. active mode form external contact user can override by changing system mode;
5. weekly schedule system operates in mode under weekly schedule, the user can change the current mode manu-
ally. System will inform about the next change of the mode under the schedule;
If any of the above mentioned functions has changed it’s state into Stand-by mode, system checks if the mode is not blocked at the current time. If the
mode is blocked, the system returns to previous mode.
Saving settings after power cut
After a power cut the unit continues operation at the speed and temperature set before the accident.
Smooth temperature control during fans speed reduction
This functions saves the energy at the change of the air ow. It is active when the fans are controlled by percentage, because PID controllers does this
automatically when controlling by the air ow or pressure. If the user sets a higher air ow, this function is gradually starting to increase air ow and
when getting closer to the set value gradually reduces the speed, this way temperature control function experiences less stress, less energy is being
wasted. If the user reduces the air ow, the system stops the coolers and heaters in order to avoid heat/cold wave and gradually changes the air ow.
After the reduction of air ow heaters and coolers continue to operate on demand.
Air ow control
Indication of the air ow in percentage, pressure or air quantity depending on the system conguration.
PID controllers adjusting
The coefcients of all the PID controller are adjusted. The quantity of the coefcients depends on the system conguration.
Manual control
Manual control of the components function activates/deactivates components manually. Components are controlled by digital and analog outputs.
Analogue outputs are controlled in percent, while digital - “on/off”. By default, all components are specied as “Auto” state, which means that the com-
ponent is controlled under the ventilation logics.

Date and time setting
For the proper operation of schedule, events, and heating season functions it is necessary to set the date and time.
Weekly schedule
Weekly schedule consists of 10 weekly events. They can be added, deleted, activated and deactivated. Time, mode and day of the week are set for
one event.
Holiday schedule
The unit operates at one specied mode during the holiday period. The user can check and change the specied holiday period. The active mode of
this function cannot be changed by any other function except for security functions.
Heating season
To protect some of the system parts from cold outdoor air during the cold season it is recommended to keep the unit in operation mode, it can be done
by setting the heating season function which blocks the turn off function of the unit. Water heaters must be turned on during entire cold season period.
The heating season can be set up:
• manually;
• by date;
• by average three-day outdoor air temperature. Average temperature is being calculated only when outdoor air preheater is turned off.
BOOST
BOOST function is used for intensive ventilation of the premises. This function activates the maximum air ow (4th speed). Intensive ventilation must
be temporary, i.e. there must be nite condition (e. g. CO2 limit, time period). The reason for the restriction - protection against dryness. High air ow
reduces humidity and dry air harmful to health.
Night cooling
This function is used for energy saving. Cool night air is used to cool the indoor air in the morning. Function actives for a specied time when the
outside and the room air temperature is higher than the “SetPoint” - 10C (default setting) and the room air temperature is at least 2 degrees warmer
than the outside air. In other cases, the function is inactive. When the function is active, fan operates at speed 3 and heat exchanger cools the air till
the set air temperature limit “SetPoint“.
Event history
The system records 50 recent events (faults, warnings, re damper testing results, etc.). Event description and time is saved in the history.
Filter timer setting
Air lter timer informs the user about time to change the lters. After changing the lters timer should be reset. The user can always see how many
days are left until the next change of the lters. The time is calculated only when the fans are operating.
Protection from dryness
This function protects the premises from dryness. If the function is active, it calculates three days room extract air humidity average. If the average is
lower than 30% in comfort mode, fans start to operate at speed 2. The user is informed about the active protection function and reduced air ow. If the
humidity average is higher than 30% function is deactivated manually, fans star to operate at speed 3 in comfort mode.
Supply air temperature control and compensation
Optional temperature control by supply or extract air temperature. Indication of the permissible minimum and maximum supply air temperature limits
and compensation percent.
Stand-by mode blocking
This function protects the system against impermissible turning off of the unit. Allowed period for turn off in 12 hours should be indicated. If the turn off
is blocked and the system is off, the system calculates the time and informs the user about the remaining time. Possible function modes:
• Never - always allow always turn off;
• Always – always block turning off;
• On Heating Season - block turning off during the heating (winter) season;
• On Cooling Season - block turning off during cooling (summer) season.
System mode from external contact
This function activates the desired mode from the external contact. Type of signal, which will be fed to the input, should be indicated. Possible types
of signals:
• None- not used;
• Push – by impulse on/off;
• On/Off – On/Off by the switch;
• PIR – by PIR sensor.
Fans speed from external contact
This function activates/de activates boost function or desired fans speed combination from external contact. Type of signal, which will be fed to the
input, and its control options should be indicated. Possible signal types and combinations:
• None - not used;
• CUSTOM push - On/Off by the impulse signal;
• CUSTOM On/Off – by the switch On/Off;
• BOOST push – On/Off by the impulse or switch.
CO2 reduction function
This function helps to maintain proper indoor air quality. Indicate the desired level of CO2 and permissible overrun limit. When CO2 exceeds the permis-
sible limit, the CO2 reduction is activated increasing air ow, the information displayed for the user. When CO2 level reaches a set value, the function

19
Smarty 2R VE
www.salda.lt
of CO2 reduction is switched off.
Air ow reduction by the temperature
If the supply air temperature is more important than the air ow, it is possible to turn on air ow reduction depending on the temperature function. If all
the heating power is consumed on the desired temperature support and the desired result is not reached, then reduction of the air ow starts in order
to support enough power for required temperature maintenance.
Supply air heater
Supply air heaters are designed to heat the supplied air in addition, when a heat exchanger heating power is not enough. The heater is controlled by
the PID controller according to the data of set and supply air temperature sensor. One supply air heater can be connected to the system. It can be
either electrical or water. Supply air heater identication versions:
• None;
• Electrical 0..10;
• Electrical On/Off;
• Hydraulic.
Electrical heaters cooling
If an electric heater had been used and system is required to stop the fan, then before stopping the fan heater is turned off and cooled by blowing for
given time period. The user is informed about active heaters cooling function.
Dampers control
Before starting the fans dampers are opened, when fans are stopped dampers are closed. It is possible to congure damper opening/closing time.
By default 30 s.
• Supply/Extract air damper – None, On/Off, Open/Close - open before starting the fan and close when fans are stopped;
• Recirculation damper – Disabled/Enabled – used in heat exchangers anti-frost protection function;
• Fire damper – None, One switch, Two switches.
If On/Off or Open/Close damper type is specied, it is necessary to indicate the opening time.
Fire dampers can be tested either manually or automatically every specied date range. Test results are stored in the events history. The user can
specify the hour of damper testing (user settings), air ow is stopped during the testing.
The enforced stop function
Used to block all the control algorithms. Helpful for service maintenance.
Cold-Heat recuperation
This function controls heat exchanger. Heat recovery takes place when the extracted indoor air is warmer than the outdoor air. Plate heat exchanger
power is controlled with bypass damper. When the damper is closed, full capacity of the heat exchanger is used. After opening the damper the capac-
ity of the heat exchanger is being reduced.
Chimney sweep function
This function works by adjusting the fans speed from external contact function, an external contact is connected to the replace door switch. When
replace door is opened the exhaust air fan is stopped and supply air fan is started at full capacity. This creates overpressure in the room for better
traction of smoke through the chimney.
Default parameters resetting
If the setting of the parameters caused incorrect operation of the system, it is always possible to restore the default settings. User settings, such as
weekly schedule, won’t be changed by restoring to default settings.
Filter protection:
timer limit – air lters time limit is set in service menu. Reset the lters timer after the change of the lters. User can also reset the lters timer. (antras
sakinys kartojasi “air lters time limit is set in service menu”). The maximum permitted time - 1 year. Time calculates only when fans are in operation;
press rely type – it is indicated if the press rely is used for lter protection. Possible combinations:
• None;
• Supply;
• Extract;
• Both.
Fans protection by RPM
If fans have “Tacho” outputs it is possible to identify fan failure by their rotational speed. If the system gives a signal for fans to rotate, but they do not,
the protection is activated, the system stops and displays a warning.
Supply air temperature protection
This function protects against undesirable supply air temperature. Minimal and maximal supply air temperature, permissible time and protection ac-
tions are indicated. That protection is limited by the user‘s as well as other functions supply air temperature settings. By default, the minimum permitted
supply air temperature is + 16.5 °C, and maximum + 35.0 °C. If the supply air temperature drops below 5 oC, equipment stops despite these protection
settings!
Fire protection from external contact
Normal contact state NC/NO and actions in case of re are indicated:
• Stop system;
• Boost supply air;
• Boost extract air;
• Boost supply and extract air.
Fans protection by integrated protection
This protection is active when fans protection function by RPM is off. The fan protection input is active, the system stops.

Electric heaters thermo protection
Electric heater may have two protections. One is automatic, the other manual. Automatic protection automatically shuts down when the heater is
cooled, manual protection must be turned off by pressing the switch which is on the heater.
When the protection activates the heater and its power circuit turns off, the warning is displayed. Minimal shut-off time - 5 minutes. When the protection
recovers, the warning is no longer displayed.
Temperature sensor failure protection
Ability to specify what should be done for each temperature sensor failure event.
Available Options:
• unit is stopped and a warning is displayed;
• the unit is working in emergency mode and the warning is displayed
The system informs the user about the failure warnings and alarms. Alarms are cancelled automatically, while warnings must be cancelled manually. It
is recommended the warnings to be cancelled by a specialist after the detection of the reason for the alert. If at least one warning is active, the system
stops and external fault indication is being activated.
