System modes:

• Stand-by

• Building protection

• Economy

• Comfort

In stand-by mode the system is shut down for a permissible shutdown period (based on the stand-by mode blocking function settings).
The building protection mode is designed to protect a building against moisture accumulation. In this mode the system operates at speed 1. By default,
in this mode temperature maintenance is controlled (preferred temperature is indicated). However, if necessary, temperature maintenance can be
switched o󰀨.
Economy mode is designed to save energy when people are not in the room. In this mode the system operates at speed 2. By default, in this mode
temperature maintenance is controlled (preferred temperature is indicated). However, if necessary, temperature maintenance can be switched o󰀨.
Comfort mode is used when people are present in the room. In this mode the system operates at speed 3. In this mode the temperature is always
maintained.

System mode can be changed automatically by the functions (in a sequential order as indicated):

1 - Weekly Schedule
2 - Mode is activated from an external contactor
3 - User’s manual mode selection
4 - Holiday Schedule
5 - Stand-by mode blocking

Based on the weekly schedule the system decides which mode it will be operating in; however, the user may change the existing mode manually. The
system will inform when the next mode change is scheduled. After power loss the mode is selected based on the weekly schedule; however, if the
schedule is not set, the mode used before the power loss will be activated.
The user may change modes only when the mode is activated from an external contactor. The only case when the user cannot change the mode is
when the period of a holiday schedule is active. The system informs that the holiday schedule mode is active. To prevent blocking, the period of the
holiday schedule must be changed.
Stand-by mode can be blocked based on selected parameters. If at least one of the above functions changes its mode into stand-by mode, it must be
checked whether this mode is not currently blocked. If it is blocked, the previous selected mode is on.
The function order is provided below.

ule interval.

A weekly schedule consists of 10 weekly events. They can be added, deleted, activated and deactivated. One event indicates time, mode and days
of the week.
The system changes modes based on the weekly schedule only when the indicated time comes; therefore a user can always change the existing mode
manually. This schedule noties the user of the upcoming mode change by indicating the time remaining till the next event.

A holiday schedule is used when the unit has to operate in an indicated mode during holidays. The user interface shows when the schedule period is
active as the mode activated by this function (except for protections) can be changed by no-one. In order to control the system in a normal manner,
the holiday schedule period must be deactivated, i.e. zero values must be indicated or period dates must be changed. Up to ve holiday periods can
be indicated.

The winter/summer function is used to set upcoming cold periods, because some part of the system need to be protected against cold outdoor air.
During the winter period it is recommended to leave the unit on, therefore it is possible to set that the system switch-o󰀨 is blocked during the winter
period. Water heaters must be always on during the entire winter period.

temporary, i.e. it must be a nal condition (e.g. CO2 limit, time). The reason for this limitation is protection against dryness. The function is activated
manually and from the external system contactor.
The function is inactive in stand-by mode. Time limit shall be set to this function. Once the function is activated, the indicated time is set for the function
timer and time is counted till the function deactivation. This time may be adjusted in real-time, i.e. when the function is on.

This function is designed to protected premises against dryness. If the function is active, it calculates the 3-day mean humidity of extract air from the
premises. If the mean drops below 30%, fans start operating at speed 2 in comfort mode. A user is notied of the activated protection and limited air
ow.
If the humidity mean exceeds 30% or the function is switched o󰀨 manually, fans start operating at speed 3 in comfort mode.

This function is designed to save energy which is used to cool a building in the morning by cool night air.

If the function is on but not active, activation conditions are checked:

1 - System time is between function start and function end (hours/minutes).
2 - Time is every hour since the start.
3 - If “Stand-by” mode is set, the unit operates in “Building protection” for 5 minutes so that the actual temperature data is available. Temperatures

are checked after purging. If wrong temperatures are received the unit returns to “Stand-by” mode.

4 - Outdoor temperature is higher than the set outdoor temperature.
5 - Extract air temperature is higher than the set temperature.
6 - Extract air temperature is higher than the outdoor temperature by at least 2 °C.
7 - Summer time.

If all conditions are fullled the unit starts operating in “Comfort” mode (without temperature maintenance). The main window shows that the night
cooling function is active.

Where the function is active, the deactivation conditions are regularly checked:

1 - Time does not correspond to the start/end interval.
2 - Extract air temperature drops below the set point.
3 - Outdoor air temperature drops below the set point.
4 - Mode other than “Comfort” was switched or the unit has been shut down

If at least one condition is correct, the unit switches o󰀨 the night cooling function and it switches to the mode that was on prior to activating the function.

The air lter timer is designed to inform the user on lter replacement. After lters have been replaced, the timer must be reset. The user can always
see how many days remain till the lter replacement. When the time expires, the warning on lter replacement is displayed. The lter timer limit can
be set in the service environment. Maximum permissible time – 1 year. Time is calculated only when fans are rotating.
This timer also shall be automatically reset to cancel lter clogging warning.

The system noties the user of system failures by alarms and warnings. Warnings are cancelled automatically, whereas alarms must be cancelled
manually. It is recommended that alarms are cancelled by a specialist prior to nding out the causes of the alarm. If at least one alarm is active, the
system is shut down and external failure indication is activated. All possible alarms and warnings are provided in the table below.

The system records 50 recent events (failures, alarms, re damper testing results, etc.). The log stores the event description and time.

Every unit has a conguration version specic to this unit, which is saved in the production line. Besides the system conguration and software ver­sions the running time is also displayed since the unit manufacture date. Running time is calculated when fans are rotating.

4 air ows are used in the system and they are dedicated to specic modes:

1. Building protection

2. Economy

3. Comfort

4. “BOOST” function

The ows are displayed in ascending order, i.e. when “Comfort” mode is set to lower air ow than that of “Economy” one, the “Economy” mode air ow
will be reduced automatically. With respect to the system conguration, air ows are indicated in percentage or pressure or amounts of air. 100% value
of air ow is indicated in service environment.

Smarty 2X/3X V

This function is used to adjust the coe󰀩cients of the existing PID controllers. The number of coe󰀩cients depends on the system conguration. If the
system operation for any reasons is unstable (uctuating), PID coe󰀩cients may be adjusted. We recommend this to be done by a specialist.

The function of manual control of components is designed to activate/deactivate the components manually. Components are controlled by digital and
analogue outputs. Analogue outputs are controlled in percentage, and digital output are controlled by “on/o󰀨”. By default, all components are attributed
“Auto” status which means that a component is controlled based on ventilation logic. Components are displayed by the system conguration. Settings
must be saved so that they remain the same after power loss.
The minimum unit consumption in stand-by mode is ensured only when all the manual control components are set to “Auto” position.
Prior to using the manual control function, it is recommended to activate the force shutdown function which blocks the ventilation logic functions.
This function may be useful, if you need to check whether everything is properly connected. Moreover, in the event of failure, certain component can
be activated so that the unit operates irrespective of sensors and protections. Of course, this method should be applied in exceptional cases until the
failure is rectied.
If an external (“Remote”) type of a temperature sensor is displayed, the sensor temperature may be indicated manually, and the values may be indi­cated via the Modbus interface.

This function is used to monitor controller input and output values, versions of connected modules, system date and time, fan speeds, temperatures,
CO2 value, pressure, etc. The amount of information depends on the system conguration. This tool is designed for preventive maintenance of the
system.

This function is designed to protect the system against the impermissible unit shutdown. It is recommended to limit the unit shutdown up to 1 hour
within 12 hours during the winter period. Possible function modes:

• Always allow shutdown

• Block shutdown

• Block shutdown during winter period

• Block shutdown during summer period

It must be indicated for the function for how long the switch-o󰀨 is permissible within 12 hours. If the switch-o󰀨 is blocked and the system is shut down,
the system counts the time and informs the user on the remaining time.
If the time has expired and stand-by mode is blocked, the user is informed by the function indication.

Temperature may be indicated for supply air or room temperature. The temperature can be maintained based on supply or extract air temperature. If
control by room temperature is selected, the function calculates the temperature to be supplied to maintain proper room temperature. Temperature is
limited based on supply air temperature permissible limits.
The ventilation unit is not designed to heat premises; therefore it is not necessary to use full capacity for low temperature di󰀨erences as the compensa­tion in percentage is provided for in this function. This parameter indicates a percentage part of the temperature di󰀨erence (between the set point and
room temperature) to be compensated by this function. E.g. set point is 20°C, room temperature is 16°C, compensation is 50%, di󰀨erence between
the indicated and existing temperatures is 20-16=4°C. Since 50% is compensated, then 4*50%=2°C, and when the received value is added to the set
point we get the required supply air temperature 2+20=22°C. As this temperature is within the supply air temperature protection limits, it is not limited.
In this case the system will maintain the supply air temperature at 22°C. The closer room temperature is to the set point (20°C), the closer required
supply air temperature is to 20°C.
It can be also too hot in the room, therefore this function is compensating in both directions (both heats and cools). The required (compensated) tem­perature is displayed in the window “Monitoring” (“Required supply t.”). If it is displayed that the required temperature is equal to 0°C it means that the
supply air temperature maintenance is switched o󰀨.

The supply air temperature is maintained by the following components (in a sequential order as indicated):

• Fans (if too hot the speed is decreased)

• Cooler

• Recirculation damper (in case of favourable outdoor air temperature)

• Bypass damper (in case of favourable outdoor air temperature)

• Heater

• Fans (if too cold the speed is decreased)

The system rst of all tries to maintain the supply air temperature by means of a heat exchanger. If plate heat exchanger is used, the bypass damper is
used. The heat exchanger can both cool and heat with respect to outdoor and room air temperatures. The heat exchanger is controlled based on PID
controller assigned to it. When the heat exchanger operates at full capacity and required temperature is not reached, the recirculation damper, then
the heater or cooler is activated (if necessary) etc. Only the components congured for temperature maintenance are activated. From one component
to another one the system switches over in 60 seconds.

This function is designed to limit the supply air temperature. The minimum and maximum supply air temperatures are indicated for the function as well
as permissible time and protection actions (display only an alarm or shut down the unit). This function limits supply air temperature set by the user
and other functions. If the temperature is controlled based on room temperature, this function does not allow supplying warmer or cooler air than that
indicated in the protection.
If the system fails to maintain the right temperature, i.e. supply air temperature remains outside the limits for an indicated period of time, the unit is shut
down (if indicated) and alarm is displayed. By default, the minimum permissible supply air temperature is 16.5°C, maximum temperature is 40.0°C.

This function is designed to activate the preferred system mode by means of an external contactor. The function indicates a type of a signal to be sent
to the input.

Possible types of signals:

• Not used

www.salda.lt

23

Smarty 2X/3X V

• Button click. Selected system mode is activated. Function is activated when it receives an impulse. It is deactivated when it receives the impulse

again.

• On/o. Selected system mode is activated. Mode is active when contactor is on.

• PIR sensor. When the sensor is activated, the selected system mode is activated. If the signal is not received within 30 minutes, the mode is

deactivated.

This function is designed to activate/deactivate the boost ventilation function or preferred combination of fan speeds by means of an external contactor.
The function indicates a type of a signal to be sent to the input and components controlled by it. Possible combinations of signal types and functions:

• Not used.

• On/o. Selected fan speed combination is activated. Function is on when contactor is on.

• Button click. Selected fan speed combination is activated. Function is activated when it receives an impulse. It is deactivated when it receives

the impulse again.

• On/o. Boost ventilation function is controlled. Function is on when contactor is on. If the boost ventilation function is not terminated by means of

this function within the boost ventilation time limit, force shutdown is used after the time expires.

• Button click. Boost ventilation function is controlled. Function is activated when it receives an impulse. It is deactivated when it receives the

impulse again.

• If the boost ventilation function is not terminated by means of this function within the boost ventilation time limit, force shutdown is used after the
time expires.
It is also indicated whether boost ventilation will be activated or combination of fan speeds is preferred, i.e. it is possible to indicate preferred supply
and extract air fan speeds individually.

1.24.1 Chimney Sweep Function

When the function of fan speed from an external contactor is used, the function can be adjusted so that it helps to light a re in a replace. The external
contactor may be connected to the switch of the replace door. It must be indicated in the function that “On/O󰀨” signal will be used, minimum extract
air fan speed and maximum supply air fan speed must be indicated. This combination will create the pressure in a room, which will improve the smoke
extract through a chimney as well as burning. When the replace door is opened, the function will be activated. When the door is closed, the function
will be deactivated.

1.25.1 Filter Timer Settings

Filter timer limit is set to the function. The maximum setting can be 1 year.

1.25.2 Air Filter Protections based on Pressure Relays (only Smarty 2X/3X V 1.1)

The function checks if the lters are clogged by means of pressure switches. Available function operating combinations:

• Not available

• Supply air

• Extract air

• Supply and extract air
When pressure switches are activated an alarm is displayed.

A re protection signal can be connected to this controller. By default, the signal input is normally closed (NC). Input conguration can be changed.
When the signal is lost for an indicated period of time, the protection is activated, warning is displayed and indicated mode is performed. Protection
is terminated upon cancelling the warning. It is possible to set a timespan during which the system does not activate. It is possible to select system
behaviour when this function activates:

• Stop the system

• Run supply air fan in full speed and stop extract air fan

• Run extract air fan in full speed and stop supply air fan

• Run supply and extract air fans in full speed

This function is designed to maintain a proper quality of room air.
Where CO2 exceeds the permissible limit, CO2 reduction is activated and air ow is increased. When CO2 reaches the set point, this function is
switched o󰀨.

Login passwords can be changed in the service environment. To change passwords of service and adjuster environments the password must be
activated.
The password consists of 4 digits. If password is not necessary for parameter review and change, set the password (number “0”).

This function allows to restore the factory defaults.

The preferred air ow can be indicated in percentage or 4 xed speeds where each of them is dedicated to a relevant system mode:

1. Building protection

2. Economy

3. Comfort

4. “BOOST” function

Fan speed can be controlled based on:

• Percentage value. Speed percentage is indicated. 0% corresponds to 0V control signal voltage, 100% corresponds to 10V control signal voltage.

• Pressure. The maximum system pressure is indicated which means 100% air ow.

24

www.salda.lt

Smarty 2X/3X V

• Air ow (m3/h). Supply and extract air factor K and maximum system air ow (m3/h) is indicated which means 100% air ow.

The fans are controlled by PID controller based on air ow and pressure. Every fan is controlled individually.
It is possible to limit the minimum and maximum fan control signal voltage. By default, minimum 2V voltage is indicated which means that 0V voltage
signal is sent when fans are o󰀨, and 2V voltage signal is immediately sent when rotation is required.

1.30.1 Fan Protection based on Rotating Speed

If fans have “tacho” outputs, the fan failure can be identied based on their rotating speed. If the system sends the signal for fans to rotate and they
fail to rotate, then protection is activated, system operation is shut down and alarm is displayed.

1.30.2 Air Flow Protection based on Pressure (only in Smarty 3X V 1.1 version)

Where this protection is activated the system must reach the required pressure or air ow. If the system fails to reach the required air ow or pressure
within the indicated period of time, the protection is activated, unit is shut down and alarm is displayed. This may happen due to failures of air ow/
pressure transmitters, pressure hose defect, clogged ow, impeller defects, incorrect factor K, etc.

1.30.3 Protection of Premises with a Fireplace (only in Smarty 2X/3X V 1.1 versions)

This protection is used for premises with a replace. It protects against improper air pressure di󰀨erence which can result in presence of ue gas
(carbon black) in premises. Pressure switch must be connected to the assigned digital input to measure pressure drop in the premises and inside the
chimney. Upon activation of this protection the pressure switch will shut down the unit and display the alarm.

1.30.4 Slowing Down Air Flows based on Temperature

If supply air temperature is more important than air ow, the function of air ow slowing down based on temperature may be switched on. If full heat­ing/cooling capacity is used to reach the desired temperature and it is not reached, the air ow is slowed down to have su󰀩cient power to maintain
the desired temperature.

1.30.5 Continuous Temperature Maintenance by Slowing Fans Down

This function is designed to save energy when air ow is changed. It is active when fans are controlled based on percentage, since PID controllers
do it automatically if it is controlled based on air ows or pressure. Fast change of air ows imbalances the temperature maintenance function and
consumes energy until it is balanced again. If a user sets a higher air ow, this function starts gradually increasing the air ow and gradually slows
down the conversion speed when it approaches the set value. In this way the temperature maintenance function su󰀨ers less stress and consumes less
energy. If the user reduces the air ow, the system switches o󰀨 coolers and heaters to prevent from the heat/cold wave and gradually changes the air
ow. After the air ow has been reduced, heaters and coolers continue operating as required.

The following dampers can be connected to the system:

• Supply/extract air dampers (On/O󰀨 or OpenClose type). The damper is opened prior to starting fans and closed after fan shutdown.

If On/O󰀨 or OpenClose type damper is indicated, proper opening time must be indicated.

1.32.1 Cold - Heat Recuperation (no bypass dampers in Smarty 2X/3X V 1.3 versions)

Cold-heat recuperation function is designed to control a heat exchanger. The plate heat exchanger power is controlled by means of a bypass damper.
When the damper is closed, the heat exchanger is used at full capacity. When opening the damper the heat exchanger power is reduced.
The heat exchanger can both heat and cool based on outdoor air temperature. If it is colder outdoors than in the room, the heat exchanger pre-heats
outdoor air by using the room air heat. If it is colder in the room than outdoors, the heat exchanger cools down the outdoor air by using the room air.
The heat exchanger power is reduced to the minimum when the system required supply air temperature is the same as outdoor air temperature. The
higher the di󰀨erence between required and supply air temperatures, the higher the heat exchanger power is used. Only when the heat exchanger is
used at full capacity, it is allowed to activate other heating/cooling components.
The coe󰀩cients of the heat exchanger, heat exchanger PID controller are set to this function.
PID controller output limits are set to bypass damper from which point to start operation. If the bypass damper opens only at several percent the noise
can occur, thus its minimal opening limit is limited. This limit also applies when approaching the full opening.

1.32.2 Plate Heat Exchanger Anti-Frost Protection

This protection is designed to protect the heat exchanger against accumulation of ice as the accumulated ice can damage the structure of the heat
exchanger. Protection activation/deactivation is possible based on:

• Indicated outdoor air temperature

• Indicated extract air temperature

• ndicated extract air temperature di󰀨erence from the calculated freezing point (this temperature is calculated based on outdoor air temperature,

room air temperature and humidity)

• Based on pressure switch

Possible safeguards (performed in a sequential order as indicated):

1 - Reduction of supply air ow (-30 %)
2 - Outdoor air heating with pre-heater
3 - Bypass damper opening
4 - Unit shut down (based on supply air temperature)

Protection activation conditions and safeguards can be activated optionally. Also time is indicated to switch over from one protection to another one
after time expires. If at least one activation condition is fullled, the protection is activated and warning is displayed. It begins from the least energy

www.salda.lt

25

Smarty 2X/3X V

consuming safeguards, i.e. if allowed, the supply air ow is reduced. If the protection does not help during the indicated period of time, then the other
protection is activated. Switching over from one protection to another one is done in a sequential order.
Outdoor and extract air recirculation is e󰀨ective and energy-saving protection, but supplies the extract air to the supply air ow.
Outdoor air pre-heater can be used at full capacity or to maintain the set temperature. If temperature maintenance is selected, at rst the activated
protection will switch on the pre-heater at full capacity for a certain time period and then maintain the indicated temperature.
When using the bypass damper the supply air heater must be connected. The opening of the damper will reduce the cold air ow through the heat
exchanger, but it will cool down the supply air which must be heated up by the supply air heater. This protection slowly opens the bypass damper as
far as activation conditions are fullled. When suitable conditions are met the damper will be stopped for 5 min. and then slowly closed. If the supply
air temperature drops below the permissible limit (insu󰀩cient heater power), then the damper will be closed by force based on supply air temperature.

Only either pre-heater or heater can be connected to
MiniMCB basic board.

1.33.1 Supply Air Heater

Supply air heaters are designed to additionally pre-heat the supply air when the heat exchanger heating power is insu󰀩cient. The heater is controlled
by means of a PID controller based on temperature indicated by the system and data of the supply air temperature sensor. One supply air heater can
be connected to this system.

Possible options of supply air heaters in this system:

• Supply air heater is not used.

• Electric heater is controlled by 0..10VDC signal

• Electric heater is controlled by On/O󰀨 signal. PWM control interval in seconds is indicated to control this heater.

Also it is possible to swap the connectors of pre-heater and heater protections and control signals.

1.33.2 Electric Heater Thermal Protections

The electric heater can have two protections. One is automatic, another one is manual. The automatic protection is automatically o󰀨 when the heater
cools down, whereas the manual protection must be deactivated by pressing the switch on the heater.
When the automatic protection is activated, the heater and its power circuit are o󰀨, warning is displayed. Minimum switch-o󰀨 time – 5 minutes. When
the protection is restored, the warning is no longer displayed.
If the manual protection is activated, the heater and its power circuit are o󰀨, an alarm is displayed, the indicated protection action is performed. By de­fault, full speed blowing is performed so that maximum cooling of the heater is ensured as there is a probability that the manual protection can jam and
leave the heater running. Of course, if the manual protection is properly activated, the supply air temperature can quickly drop to critical temperature
during winter period if full speed blowing is on and the system would be shut down in any case.

1.33.3 Electric Heater Cooling

If an electric heater is used and the system wants to stop the fan, heaters are switched o󰀨 prior to shutting fans down and they are cooled down by
blowing for an indicated period of time. A user is notied of heater cooling.

1.33.4 Outdoor Air Pre-Heater (not applicable to Smarty 2X/3X V 1.1 versions as they have integrated internal pre-heater)

Outdoor air pre-heaters are controlled based on anti-frost protection. Possible options of outdoor air heaters in this system:

• Supply air pre-heater is not used.

• Electric pre-heater is controlled by 0..10VDC signal

• Electric pre-heater is controlled by On/O󰀨 signal. PWM control interval in seconds is indicated to control this heater.

In this system it is possible to indicate a normal status of every digital input, i.e. indicate whether the contactor is normally open or closed (Normally
Open (NO), Normally Closed (NC)). The re protection contactor must be NC as in case of re the contactor may break if a cable burns.

In this system two 0-10VDC air quality sensors and eight temperature sensors may be used.

The following can be connected to two 0-10VDC inputs:

• Supply air RH sensor

• Extract air CO2 sensor

• Extract air RH sensor

• Supply air pressure sensor

• Extract air pressure sensor

0V and 10V values are indicated for these sensors. Types of temperature sensors:

• “None” – sensor is not connected

• “Remote” – remote sensor. Sensor temperature can be indicated via Modbus.

• “NTC 10K 3997” – NTC sensor is connected.

In this system all types of sensors and failure action are indicated. Possible failure actions:

• Do nothing – only warning is displayed

• Shut down the system – the system is shutdown, alarm is displayed.

• Emergency mode – operation is continued, but sensor-dependent functions are switched o󰀨. Warning is displayed.

MiniMCB controller has two independent communications lines. One line is dedicated for remote control panels, another one is for BMS network.
The line dedicated to the BMS network is galvanized. Used communication protocol – Modbus RTU.

Unit controller miniMCB has integrated protection against short-circuit.
F1 - 1A (5x20) controller power supply 230VAC/24VDC protection.

To ensure safe maintenance of the unit, it is necessary to
remove the plug from the power network.

Prior to start-up the system must be thoroughly cleaned. Check whether:

• operation systems and unit elements as well as automation and automation devices were not damaged during installation,

• all consumers are connected to power supply and t for service,

• all necessary automation elements are installed and connected to power supply and miniMCB basic, EX1 terminal blocks,

• cable connection to miniMCB basic, EX1 terminal blocks comply with the existing power connection diagrams,

• all electrical equipment protection elements are properly connected (if they are additionally used),

• cables and wires correspond to all applicable safety and functional requirements, diameters, etc.,

• earthing and protection systems are properly installed,

• condition of all seals and sealing surfaces is proper.

Failure Cause Explanation / corrective actions

Unit is not operating No supply voltages

Two-pole protection device is o󰀨 or a current
leakage relay is active (if installed by the in­staller)

Air supply heater or heater is not operating or
malfunctioning (if installed)

Too low air ow at rated fan speed Clogged supply and/or extract air lter(s) Filter replacement needed

Filters are clogged and no message is shown
on the remote control

The controller is used with NTC sensors.
Default sensor NTC
10 kΩ β (25/85) 3977
Limits for temperature measurement -30 ...105 °C.
Accuracy - ± 0,2 %
Safety class – IP-54

Too low air ow in air ducts activates automatic
protection

Manual protection is activated

Wrong time in lter timers
