Danger: Fumes

Salda Antifrost system uses dis-balancing of the air ow and it may cause negative pressure in premises. Great care should be taken

when using at the same time in premises as another heating appliance what depend on the air in premises. Such appliances include

gas, oil, wood or coal-red boilers and heaters, replaces, continuous ow or other water heaters, gas hobs, cookers or ovens which

draw air in from the room and duct exhaust gases out through a chimney or extraction ducting. The heating appliance can be starved
of oxygen, impairing combustion. In exceptional cases harmful gases could be drawn out of the chimney or extraction ducting back
into the room. In this case we strictly recommend to turn o󰀨 Salda Antifrost and use an external preheater for heat exchanger anti-frost
protection (see Salda Antifrost function on the Remote controller manual).

5.5. MOUNTING

• Installation should only be performed by qualied and trained sta󰀨.

• 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 recommended 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.

Mounting on the wall:

a) To reduce the vibration stick the insulating tape on the unit‘s casing side which touches the wall before mounting the unit on the wall.
b) The unit has to be mounted on the mounting brackets.
c) AHU mounting drawing.
d) After the unit is mounted two wall bracket tabs has to be folded to 90o angle by pliers to avoid the accident fall of the unit.

5.5.2. PLACE REQUIREMENTS FOR THE EQUIPMENT AND MOUNTING POSITIONS

1. The installation position only in the horizontal direction.

2. Install the supporting legs.

3. AmberAir Compact are assembled from separate sections.

4. They must be adjusted without a gradient.

5. Leave space in the front (2xL) that it would be su󰀩cient to open the doors and to remove or install a required component.

EN | 11SMARTY RV v2019.12

5.5.3. CONNECTION OF AIR DUCTS

• Connected air ducts must be straight and have their own xing.

• Make sure that the fans can not be accessed through air duct heads. If it is possible to access the fan, protective grid should be installed. You
can choose it in our website.

• Do not reduce the diameter of the piping near air inlet or exhaust ducts. If you want to reduce the speed of air in the system, drop of pressure
and noise level, you can increase the diameter.

• In order to reduce the level of the noise in the air supply system, install silencers (see chapter on their installation).

• In order to reduce air loss in the system, the air ducts and prole parts should be of class C and higher. Their catalog can be found in our

website.

• If air handling unit is installed in heated premises, outdoor and exhaust air ducts must be insulated in order to avoid heat loses and condensing.
If AHU is installed outdoors, it’s recommended to insulate all the air ducts.

• It is recommended to maintain a distance of up to 8 meters between air intake and air exhaust ducts. Air supplying system should be installed
further from potential air pollution sources.

• Use holders while installing air ducts next to the ventilation equipment. They suppress vibration and ensure a rm installation of various system

parts.

• Necessary holders can be found in our catalog or website.

• A common mistake is that air ducts are attached to improper airow connection. On the ventilation equipment there are signs, indicating the air

duct to be connected. Before starting the system carefully check whether the work was performed properly.

5.5.4. AIR FLOW

The maintenance side can be changed for the ventilation unit, i.e. it can be mounted with the left ambient air inlet or the right ambient air inlet. That
can be implemented by switching over the back door and the front door. The default version of the ventilation unit is right.

6.4. FANS MAINTENANCE

• Maintenance should be performed only by experienced and trained sta󰀨.

• 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 sta󰀨 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.

7.4. DESCRIPTION OF THE UNITS FUNCTIONS

All functions indicated in this section are installed in the software of the control board. However, operation and control of the device depends on

the following:

1. Selected control panel. Full functionality and conguration possibility can be assured only by MB-Gateway web interface SA-Control, SALDA
AIR app.

2. Connected external devices: external heaters, dampers, sensors and etc. (see the description of the acquired air handling system).

3. Internal components of the device: type of heat exchanger (plate or rotor), integrated dampers, sensors and etc. (see components of the
chosen device).

4. Control board type.

Air Handling Unit uses MCB board.

The unit can be congured only with SA-Control remote con trol panel, MB-Gateway web application or SALDA AIR app.

The following control board functions can be fully con trolled only with SA-Control remote con trol panel, MB-Gateway web
application or SALDA AIR app. In case of Stouch remote con trol panel use the description of remote control panel functions
for MCB control board.

7.4.1. SYSTEM MODES

• Stand-by;

• Building protection;

• Economy;

• Comfort.

18 | EN SMARTY RV v2019.12

In Stand-by mode the system is shut down for a permissible period (based on the Stand-by mode blocking function settings).

The Building protection mode is designed to protect premises against moisture accumulation. The system operates at speed 1. Based
on manufacturer’s parameters (by default) this mode controls the temperature (the desirable one is indicated), but, if necessary, it can

be switched o󰀨, i.e. to activate the energy saving mode. Also, if necessary, full recirculation function is activated. (ADJUSTER › USER SETTINGS
› BUILDING PROTECTION MODE TEMPERATURE or USER › MENU › SETTINGS › BUILDING PROTECTION).

After activating the energy saving mode, temperature is maintained only by the heat exchanger. It will seek to maintain the current
temperature in the room; however, if the supply air temperature falls below the minimal supply air temperature level, heaters will be
activated and they will maintain a temperature one degree above the minimum. Also, if the supply air temperature rises above the
maximal supply air temperature level, coolers will be activated and they will maintain a temperature one degree below the maximum.

Economy mode is designed to save energy when people are absent from the premises. The system operates at speed 2. Based on
manufacturer’s parameters this mode controls the temperature maintaining (the desirable one is indicated), but, if necessary, it can

be switched o󰀨, i.e. to activate the energy saving mode. Also full recirculation function is activated. (ADJUSTER › USER SETTINGS › ECONOMY MODE
TEMPERATURE or USER › MENU › SETTINGS › ECONOMY MODE).

Comfort mode is running when people are present in the premises. The system operates at speed 3. In this mode the temperature is
always maintained – it is set in the main window (ADJUSTER › VENTILATION CONTROL or USER › SET POINT).

7.4.2. SYSTEM CONTROL

System modes are changed by the following functions (indicated in a sequential order):

• Weekly Schedule;

• Switching on is activated from an external contactor;

• Manual mode selection;

• Holiday Schedule;

• Stand-by mode blocking.

Based on the Weekly Schedule the system decides in what mode it will be operating; however, the user may change it manually. The system
informs when the next mode change is scheduled. After power loss the mode is selected based on the Weekly Schedule; however, if it is not set,
the mode that was set before the power loss will be activated.
The user may change modes even when the switching on is activated from an external contactor. The only case when it is not possible – active
period of Holiday Schedule of which the system informs and which must be changed to avoid blocking.
Stand-by mode can be blocked by 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 mode shall be activated.

The function order is provided below.

7.4.4. SETTING DATE AND TIME

For smooth execution of schedules, event log and winter/summer function, it is necessary to set proper date and time in section ADJUSTER › USER SETTINGS
› DATE AND TIME SET and click a button DATE AND TIME SET. It can also be indicated in user environment USER › MENU › SETTINGS › DATE AND TIME. Fast synchronization

with the computer time is possible in user and adjuster environment.

7.4.5. SUPPLY AIR TEMPERATURE CONTROL AND COMPENSATION

Temperature for supply air or premises temperature may be indicated. In the service environment section SERVICE › MAIN › SUPPLY AIR TEMPERATURE CONTROL you
can control it based on supply or exhaust air temperature. If control by premises temperature is selected, then it is calculated what kind of air is to
be supplied so that the proper room temperature is maintained. It is limited by allowable limits of supply air temperature.

The air handling unit is not designed to heat premises, therefore it is not necessary to use full capacity for low temperature di󰀨erences – the
compensation in percentage is provided for this purpose. This parameter indicates a percentage of the temperature di󰀨erence (between the set

temperature and premises temperature) to be compensated for by this function. E.g. set point is 20 °C, temperature in the premises 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. When the received value is added to the set temperature we get the required supply air temperature – 2+20=22 °C. This temperature is not
limited as it is within the supply air temperature protection limits. In this case the system maintains the supply air temperature at 22 °C. The closer
the premises temperature is to the set temperature (20 °C), the faster the supply air temperature reaches 20 °C.
It may be too hot in the premises, therefore this function both heats and cools. Preferred (compensated) temperature is displayed in the window

MONITORING (REQUIRED SUPPLY). If the displayed temperature is 0 °C, it means that temperature maintaining of supply air is switched o󰀨.

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

• Fans (operate slower, if it is too hot);

• Recirculation valve (if the ambient air temperature is favourable);

• Water cooler;

• DX cooler;

• Recirculation damper and CO2 (in case of favorable outdoor temperature);

• Bypass damper or rotor (in case of favorable outdoor temperature);

• Recirculation damper and CO2 (in case of favorable outdoor temperature);

• DX heater;

• Water heater;

• Water cooler/heater;

• Electrical heater;

• Fans (operate slower, if it is too cold).

Firstly the system tries to maintain the supply air temperature by means of a heat exchanger. In case of a plate heat exchanger, the bypass damper
is controlled, and in case of a rotary heat exchanger, the rotor rotating speed or interval is changed. The heat exchanger can both heat and cool –

it depends on outdoor and room air temperatures. It is controlled by a PID controller whose coe󰀩cients are indicated in the adjuster environment

section ADJUSTER › PID CONTROLLERS ADJUSTING › HEAT EXCHANGER CONTROL BY SUPPLY AIR TEMPERATURE.
When the heat exchanger operates at full capacity and preferred temperature is not reached, the recirculation damper, then the heater or cooler

etc. is activated (if necessary). Only the components congured for temperature maintaining are activated. It takes 10 s for the system to switch

20 | EN SMARTY RV v2019.12

between the elements.

7.4.6. FAN CONTROL

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

• Building protection;

• Economy;

• Comfort;

• Maximum power.

Fan speed can be controlled by:

• Percentage - speed in percentage is indicated in the adjuster environment window ADJUSTER › AIR FLOWS ADJUSTING: 0 % corresponds to 0, and 100
% – 10 V control signal voltage;

• Pressure - the maximum system pressure is indicated, which based on speed settings in the adjuster environment ADJUSTER › AIR FLOWS ADJUSTING

means 100 % air-ow;

• Air-ow (m3/h) - K factors of supply and exhaust air and the maximum system air-ow (m3/h) are displayed, which based on speed settings in
the adjuster environment ADJUSTER › AIR FLOWS ADJUSTING means 100 %.

Fans based on air-ow and pressure are controlled by PID controller and its coe󰀩cients are indicated in the adjuster environment section ADJUSTER
› PID CONTROLLERS ADJUSTING › FANS SPEED CONTROL BY AIR FLOW OR PRESSURE. Each fan is controlled individually.
In the service environment window SERVICE › FANS › FANS SPEED CONTROL you can limit the minimum and maximum fan control signal voltage. Based on

manufacturer set parameters, the minimum 2V voltage is indicated, which means that 0V voltage signal is sent when fans are o󰀨, and 2V voltage

signal is immediately switched on when rotation is required.

It is possible to specify the nominal ows of supply and exhaust air. Then, the maximal air ow is calculated automatically.

7.4.7. “BOOST“ FUNCTION

Boost ventilation function is used for fast ventilation of premises. It activates the maximum air-ow (speed 4). Boost ventilation has be temporary,
i.e. it must be a nal condition (e.g. CO2 limit, time). The reason for this limitation – protection against dryness. High air ow reduces humidity, and

dry air is harmful for health.
The function is activated by pressing ON and deactivated by pressing OFF button in the BOOST section, or by means of an external contactor
(FANS SPEED SWITCH), which is congured in the service environment (SERVICE › MAIN › FANS SPEED SWITCH) section.
The function is inactive when Stand-by mode is on. Time limit is indicated (ADJUSTER › USER SETTINGS › BOOST TIMER or USER › MENU › SETTINGS › BOOST TIMER). Once the
function is activated, the time is set by the timer and the time is counted till its deactivation. It may be adjusted in real-time, i.e. when the function
is on, in ADJUSTER › VENTILATION CONTROL or in the user environment main window.

7.4.8. WEEKLY SCHEDULE

A weekly schedule consists of 10 weekly events. They can be added, deleted, activated and deactivated. One event indicates time, mode/BOOST
function, days of the week. Also it is possible to indicate the change of settable mode temperature.
The system changes modes according to the Weekly Schedule only at the indicated times, therefore a user can always change the existing mode

manually. This schedule noties of the upcoming mode change by indicating the time remaining till the next event.

The schedule is edited in user environment USER › MENU › SCHEDULE.

7.4.9. HOLIDAY SCHEDULE

This schedule is used when the unit has to operate in uniform mode during holidays. The user interface shows when the schedule period is active
as nobody can change the mode activated by this function (except for protection). 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 dates must be changed. Up to ve holiday periods can be set.

The schedule is edited in the user environment USER › MENU › HOLIDAY.

7.4.10. WINTER/SUMMER MODE

The winter/summer function is set during the cold periods, because some parts of the system have to be protected against cold outdoor air. During

winter it is recommended to leave the unit switched on, therefore it is possible to set blocking of switch-o󰀨. Water heaters must always be switched

on during the entire winter.

The winter mode may be indicated

• Manually;

• By date;

• Based on 3-day mean outdoor temperature, to be calculated only when the fresh air (outdoor) pre-heater is o󰀨.

7.4.11. DRYNESS PROTECTION

This function is designed to protect 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 set limit (30%), fans start operating in speed 2 in comfort mode. A user is notied of the activated protection
and limited air ow.
If the humidity mean exceeds set limit (30%) or the function is switched o󰀨 manually, fans start operating in speed 3 in comfort mode.
The function is switched on/o󰀨 in the section ADJUSTER › USER SETTINGS › DRYNESS PROTECTION or in the window USER › MENU › SETTINGS › OTHER.

EN | 21SMARTY RV v2019.12

7.4.12. NIGHT COOLING FUNCTION

This function is designed to save energy in the morning, when a fresh night air is used to cool down the building. The function is active only in

summer. If it is switched on but not active yet, activation conditions are checked:

• System time from function start to the end (hours/minutes);

• Time is exactly every hour from the start;

• If STAND-BY mode is set, the unit operates in BUILDING PROTECTION mode for 5 minutes so that the actual temperature data is available. The tem­perature is checked after purging. If it is not suitable, the unit returns to STAND-BY mode;

• Outdoor temperature is higher than the set outdoor temperature;

• Exhaust air temperature is higher than the set temperature;

• Exhaust air temperature is higher than the outdoor temperature by at least 2 °C;

• Summer.

If all conditions are met the unit starts operating in COMFORT mode (without temperature maintaining). The main window shows that the Night cooling

function is active. When it is active continuously, the deactivation conditions are checked:

• Time does not correspond to the start/end interval;

• Exhaust air temperature drops below the set temperature;

• Outdoor temperature drops below the set temperature;

• Mode other than COMFORT was switched or the unit has been shut down.

If at least one condition is met, the unit switches o󰀨 the Night cooling function and it switches to the mode that was on prior to activating the func­tion.
The function is congured in the section ADJUSTER › USER SETTINGS › NIGHT COOLING FUNCTION or in the window USER › MENU › SETTINGS › NIGHT COOLINGS.

7.4.13. CO2 REDUCTION FUNCTION

This function is designed to maintain a proper quality of room air. To activate it the exhaust air CO2 sensor must be connected and properly cong­ured in the service environment window SERVICE › SENSORS. When completed, the exhaust air CO2 value is displayed in the section MONITORING.
In the service environment window SERVICE › MAIN › CO2 REDUCTION FUNCTION you can switch on/o󰀨 the function, indicate preferred CO2 level and allowable
limit; when it is exceeded (CO2 set + allowable excess) CO2 is reduced, information is displayed and air-ow is increased. When CO2 reaches the

set point, reduction is switched o󰀨.

CO2 protection is inactive in the stand-by and building protection modes.

7.4.14. FILTER PROTECTIONS

Filter Timer Settings

The lter timer limit is set in the service environment window SERVICE › MAIN › AIR FILTERS PROTECTIONS. The maximum setting is 1 year.

7.4.15. SYSTEM MODE COMMUNICATION WITH EXTERNAL CONTACTOR

This function activates the preferred system switching on by means of external contactor; it indicates what signal will be sent to input. Possible

types of signals:

• Not used;

• Upon pressing a button the selected system mode is activated. After receipt of the rst impulse the function is activated, and after second
impulse – deactivated;

• On/o󰀨; selected system mode is activated. The mode is active while the contactor is on;

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

Function is set in the service environment section SERVICE › MAIN › SYSTEM MODE SWITCH.

7.4.16. FAN SPEEDS FROM AN EXTERNAL SYSTEM CONTACTOR

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 func-

tions:

• 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.

22 | EN SMARTY RV v2019.12

7.4.17. HEAT EXCHANGER CONTROL

Cold - Heat Recuperation

Cold-heat recovery function is designed to control a heat exchanger. Its power is controlled by:

• Using plate heat exchanger - bypass damper. When it is closed, the heat exchanger is operating at full capacity. Its power is reduced by open­ing the damper.

• Rotary heat exchanger power is controlled by changing its rotating speed or interval. When the rotor rotates at full speed, the heat exchanger
is used at full capacity. The power is reduced by slowing down the rotating speed or increasing the interval.

The heat exchanger can both heat and cool – it depends on air temperature. If it is colder outside than in the premises, the heat exchanger pre­heats the outdoor air by using the room heat. If it is colder in the premises than outside, the heat exchanger cools down the outdoor air temperature

by room air. Its power is reduced to the minimum when the target supply air temperature is the same as outdoor one. The higher the di󰀨erence

between the preferred and supply air temperatures, the higher heat exchanger power is used. When it is operating at maximum capacity, it is al­lowed to activate other heating/cooling components.
For this function suitable heat exchanger type is indicated in the window SERVICE › HEAT EXCHANGER and PID controller coe󰀩cients – in the window ADJUSTER
› PID CONTROLLERS ADJUSTING.

PID controller output limits are set for rotor or bypass damper, at which their operation starts.

• If rotor is controlled by 0..10 V signal, at low voltages it does not rotate, the motor heats up, thus the minimum control signal output is limited. If
On/O󰀨 rotary heat exchanger is used, PID percentage for activating the rotor is indicated in the window SERVICE › HEAT EXCHANGER.

• If the bypass damper opens only a few percent, noise can occur, thus minimum opening is limited, which also applies when coming to the full
opening. If the plate heat exchanger with a 3-way bypass damper is used, the opening time of the bypass damper is indicated in the window
SERVICE › HEAT EXCHANGER.

• If a plate heat exchanger with segment valves is controlled by an external controller is used, then the type of the bypass damper “REMOTE CONTROL
LER” is shown in the window “SERVICE › HEAT EXCHANGER”.

• If a plate heat exchanger with segment valves connected to a controller is used, then the type of the bypass damper is shown in the window
“SERVICE  HEAT EXCHANGER” as either “2 SEGMENTS” or “3 SEGMENTS”. In the case of heat recovery control, segments are closed in sequence, i.e. if heat
recovery is not required, then all the segments are closed and the bypass damper is opened.

When the fans are switched on during the heating season, the heat exchanger runs for 10 minutes at full power, until the system stabilizes.

7.4.18. SYSTEM MONITORING

The service and adjuster environment have the window MONITORING where you can monitor operation of the entire system, i.e. see controller
input and output, CO2 values, versions of connected modules, date and time, speed of fans, temperatures, pressure, etc. The amount of informa-

tion depends on the system conguration. This tool is designed for preventive maintenance of the system.

7.4.19. STAND-BY MODE BLOCKING

This function is designed to protect the system against the impermissible unit shutdown and it is recommended to limit the unit shutdown up to 1

hour within 12 hours during the winter season. Possible function modes:

• Always allow shutdown;

• Block shutdown;

• Block shutdown in winter;

• Block shutdown in summer.

It must be indicated for how long the shutdown is permissible within 12 hours. If it is blocked and the system is shut down, the system counts and
informs the user on the remaining time. This function is congured in the service environment (SERVICE › MAIN › SYSTEM BLOCKING).
If the time has expired and Stand-by mode is blocked, the user is informed by the function indication.

7.4.20. AIR FLOW ADJUSTMENT

Air-ows are adjusted in the adjuster environment window ADJUSTER › AIR FLOWS ADJUSTING. There are 4 of them in the system and they are dedicated to
specic modes:

• Building protection;

• Economy;

• Comfort;

• Maximum power (BOOST function).

Air-ows are arranged in an ascending order, i.e. upon setting lower air-ow in COMFORT mode then in ECONOMY mode, the air-ow of the latter is re­duced automatically. With respect to the system conguration, air-ows are indicated in percentage, pressure or amounts of air. 100 % value of
air-ow is indicated in service environment window SERVICE › FANS › FAN SPEED CONTROL.

7.4.21. MANUAL CONTROL OF COMPONENTS

This function manually activates/deactivates the components controlled by digital and analogue outputs. The latter ones are controlled in percent­age, and digital ones – by ON/OFF. Based on manufacturer’s parameters (by default) the status of all components is AUTO , which means that control

is based on air handling unit operating algorithm. Components are displayed by the system conguration. Settings must be saved so they remain

active after power loss.
The lowest power consumption is when the Stand-by mode is on, and position of components – AUTO.
Prior to using the manual control function, it is recommended to activate the force shutdown function, which blocks the air handling unit operating
algorithm.

EN | 23SMARTY RV v2019.12

This can be useful, if you need to check if everything is properly connected. Moreover, in the event of failure, certain components 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 the service environment window SERVICE › SENSORS displays an external (REMOTE) type of a temperature sensor, its temperature may be indicated manu­ally. The values may be indicated via the Modbus interface.

7.4.22. CHANGING PASSWORDS

In the service environment section SERVICE › MAIN › PASSWORD › PASSWORD CHANGING MODE › ON you can change login passwords. For this it is necessary to acti-
vate the change and after entering a preferred password (4 digits), click a button SET. To review and change the parameters without a password,
just set 0.

7.4.23. RESTORING FACTORY DEFAULTS

If set parameters result in incorrect operation of the system, you can always restore the factory defaults in the service environment window SERVICE
› MAIN › FACTORY SETTINGS.

8.3. ELECTRICAL CONNECTION OF THE UNITS

• Electrical connection can only be implemented by the qualied electrician in accordance with the applicable international and national electri­cal safety requirements and requirements for installation of electrical devices.

48 | EN SMARTY RV v2019.12

• Use only power source which meets the requirements specied on the device label.

• Power supply cable should be selected based on the electrical specication of the device. If the device power supply line is far from the unit,
the distance and voltage drop should be considered.

• Device must be earthed.

• Install the control panel at the designated place.

• Install the supplied connection cablebetween the control panel and the HVAC unit. It is recommended to install the control panel separately
from the power cables.

NOTE: If cable is used together with other power cables, shielded control panel cable with earthed shield should be used.
NOTE: The remote control panel can be connected and (or) disconnected only after disconnecting the power supply for the HVAC unit.

• Select the desired fan rotation speed and the supply air temperature using the remote controller.
