Information(s)

This symbol indicates that somewhere else in the manual you can ﬁ nd more information about this topic or it will refer you to a local standard.

1.2 Improper use

The Udara air heater is intended for heating systems based on hot air where both the heated and the intake air is distributed through a system of ducts.

If the appliance is used inexpertly or improperly, a situation may be created that entails danger for the user or third parties or can lead to damage to the appliance or the environment.

You may only install the Udara if you combine the appliance with the accessories listed in the manual for the combustion air supply (CAS) and ﬂ ue gas outlet (FGO).

As an installer or user you have the obligation to closely follow the instructions contained in the manual of the appliance or the possible accessories. You

must, moreover, respect all inspection and maintenance conditions

You must connect the appliance electrically in accordance with the protection degree speciﬁ ed on the nameplate and in accordance with the locally applicable regulations.

If you implement changes to the appliance that are not described in the manual, you must ask for written permission from the manufacturer.

Transgressions to these instructions will be deemed not according to the regulations and may lead to dangerous situations or material damage regarding which the manufacturer rejects any responsibility.

1.3 General safety instructions

The installation, mounting, disassembly, commissioning, maintenance and repair must only be performed by professionals. They must have all legal qualiﬁ cations and, by preference, they must have followed training at the manufacturer of the appliance.

As a user, you must closely follow the maintenance instructions. Ask your installer to go through this section if you have any questions.

1.3.1 Danger of fatal injury because of gas leaks

With regard to gas smells in buildings:

• extinguish all naked ﬂ ames (such as from smoking, cookers, etc.).

• Do not operate any doorbells, switches, plugs, telephones, entry panels or other devices

• Close the main gas valve and the gas valve on the product.

• Open windows and doors.

• Evacuate the building and stop third parties from entering the building.

• Warn the ﬁ re brigade using a telephone connection outside the building (for example, at the neighbours).

• If the leak occurs in front of the gas meter, warn the energy company.

Liquid gas is heavier than air and will collect near the ﬂ oor. If the appliance is being installed below ground level, leaking liquid gas will collect and, therefore, there will be an explosion risk.

• Ensure that liquid gas can never escape from the appliance or the gas pipe.

1.3.2 Danger of fatal injury because of ﬂ ammable

substances

Do not use or keep explosive or ﬂ ammable substances (petrol, thinner, paper, etc.) near the appliance.

1.3.3 Danger of fatal injury because of

combustion gases escaping

If ﬂ ue gases escape, this can lead to dangerous situations.

• Only use the appliance with a fully installed CAS/FGO

IHL_UDARA_2016_11_04_BEGB

• Always use the appliance with an installed front cover.

A dangerous situation may occur if the appliance is supplied with insufﬁ cient combustion air.

• Ensure there is a permanent and unobstructed air supply to the set-up room of the appliance in accordance with the applicable standards.

If you smell ﬂ ue gases or you suspect there is a combustion gas leak, you must intervene immediately.

• Open windows and doors and ventilate the building.

• Switch off the product.

• Consult your installer and have the combustion circuit checked for leaks or obstructions.

If the condensate trap is empty, ﬂ ue gas may leak.

• Always use the appliance with a fully ﬁ lled condensate trap.

1.3.4 Danger of fatal injury because of electric

shocks

If you touch components that carry a current, there is a danger of fatal injury because of an electric shock. Before you work on the product:

• Ensure that the current to the appliance has been disconnected.

• Protect against reconnection.

• Always wait a few minutes so that the capacitors in motor controls, etc., are discharged.

1.3.5 Danger of fatal injury because of changes

Unauthorised changes to the product or set-up room can lead to dangerous situations.

• Never remove, bypass or change the temperature probes in the appliance.

• Sealed parts in the appliance must not be opened.

• Never change the piping for gas or the CAS/FGO and the wiring for the voltage.

• The condensate discharge must always be present and changes must never be implemented regarding the condensate discharge.

1.3.6 Danger of ﬁ re or becoming trapped

If you want to connect the appliance without ductwork, you must:

• Install a vent on the suction opening that impedes access to the fan compartment;

• Install a vent or blow plenum on the blow hole so that there is no direct access to the heat exchanger compartment. This vent or plenum must also ensure that ﬂ ammable material cannot fall on the heat exchanger.

These accessories are available from our range. If you do not know which accessories you need, you can contact your dealer for additional information.

Some parts of the appliance can become very hot during and shortly after use.

• Only carry out activities such as maintenance after the appliance has completely cooled down.

1.3.7 Risk of corrosion damage

Chemical products such as solvents, paints, adhesives, soaps, etc., may lead to corrosion in the air heater or in the CAS/FGO.

• Ensure that the combustion air is always dust-free and is not polluted by ﬂ uorine, chlorine, sulphur and other contaminants.

• If the combustion air is being supplied through a chimney duct, it must not have been used in the past as an FGO for fuel oil devices, coal or wood burners or open ﬁ replaces.

• If the appliance is set up in launderettes, ironing parlours, swimming pool rooms, etc., the appliance must be installed in a separate set-up room in which the ambient air is free from chemical contaminants.

• Combustion air that is insufﬁ ciently dust-free can lead to an unreliable ignition and, in extreme cases, even damage to the heat exchanger because of internal dirt. If this risk exists, you must order an intake ﬁ lter for the CAS that is available as an accessory.

1.3.8 Material damage because of unsuitable

tools

In addition to conventional tools, you also need a number of speciﬁ c tools to work on or maintain the Udara appliance.

• You need a special square drill bit, size 2, to loosen the tapping screws.

• In addition, you need a set of Allen wrenches with a rounded side.

• Using a 0-10 Nm torque wrench is recommended.

• You must have a ﬂ ue gas analysing device that can measure the following substances in the ﬂ ue gases: NOx (nitrogen oxides), O2 (residual oxygen) and CO (carbon monoxide). If your appliance cannot measure NOx, it is strictly prohibited to change the adjustment of the appliance or to perform a manual calibration.

1.3.9 Material damage because of frost

If the appliance is not set up frost-free, the appliance can be damaged. If the temperature of the suctioned air drops far below freezing point, frost can even occur in the heat exchanger itself.

In such a case, a bypass must be made using the air outlet duct to the suction duct so that the suctioned air is preheated.

• Also make absolutely sure that the environment in which the appliance is being installed cannot lead to any dangers because of ﬂ oating dust and/or ﬂ ammable or corrosive substances or fumes.

IHL_UDARA_2016_11_04_BEGB

1.3.10 Material damage to the ﬂ exible gas tube

The ﬂ exible gas tube can be damaged because of a heavy load due to a weight or repeated and unnecessary bending.

• Do not suspend the burner and mixing box from the ﬂ exible corrugated gas tube during maintenance

1.3.11 Material damage after water ingress

If the appliance or parts of it are exposed to water ingress, the appliance must be put out of service immediately. All safety components that are exposed to water must, subsequently, be replaced

IHL_UDARA_2016_11_04_BEGB

2 General information

2.1 Description

Multicalor Udara air heaters are gas-ﬁ red condensing and modulating appliances with a cleaner combustion, automatically controlled direct current fans and a gas-adaptive control.

2.2 Gas category

The appliance has been set for being ﬁ red with natural gas of the second family (I2N) ex-factory. If you want to use the appliance with propane, the burner management control system must be adjusted and a new nameplate must be added to the appliance. Only an engineer appointed by the manufacture can do this.

The appliance is delivered ready for use. It is sufﬁ cient to connect the ﬂ ue gas outlet (FGO) duct, the combustion air supply (CAS) duct, the gas pipe, the condensate discharge, the air ducts and the power lines.

2.3 Standard version

The standard version of the appliance is used for the distribution of recycled air to which no more than 25% of outdoor air is added or for the distribution of outdoor air to heat recovery. The appliance will work in this mode ex-factory.

2.5.1 Upﬂ ow

Suctioning takes place at the bottom of the appliance with regard to an upﬂ ow version. The blowing out of the hot air takes place at the top of the appliance. This is also sometimes called a top blowing version.

The ﬁ lter is at the bottom of the air heater as standard. If you want to connect the appliance on its side, you must order an optional ﬁ lter frame.

If side connection is required, we recommend ordering a long tool life ﬁ lter from the accessory range and not to opt for the standard side ﬁ lter frame with regard to the Udara 40 and 50.

2.5.2 Downﬂ ow

Suctioning takes place at the top of the appliance with regard to a downﬂ ow appliance. The blowing out of the hot air takes place at the bottom of the appliance. This is also sometimes called a bottom blowing version.

DF is added to the appliance type with regard to the downﬂ ow version.

2.4 Outdoor air version

The outdoor air version of the appliance is used to distribute air to which more than 25% of outdoor air is added.

Warning!

If the appliance is deployed as an outdoor air version, you must perform the changes speciﬁ ed below to prevent damaging the appliance.

If you want to deploy the appliance as an outdoor air appliance, you must order an additional insulation set to insulate the fan compartment of the Udara air heater. This will limit condensation on the outer housing of the appliance.

In addition, the condensate trap must be installed outside the appliance using an extended hose set with regard to the upﬂ ow versions of the Udara.

The condensate hoses in the fan compartment must also be safeguarded from frost, for example, by installing thermal insulation and/or a heating ribbon around the hoses.

If the temperature of the suctioned air drops below freezing point, the condensate in the heat exchanger itself can freeze. In such a case, a bypass must be made using the air outlet duct to the suction duct so that the suctioned air is preheated. 2

2.5 Versions

The Multicalor Udara appliances are available in 2 versions: upﬂ ow and downﬂ ow.

4.1.4 Set-up room

Pay attention to the following guidelines when determining the place to set up the air heater:

• Position the appliance as closely as possible to the ﬂ ue gas outlet and the combustion air ducts.

• Position the appliance centrally in comparison to the ductwork.

• Position the appliance on a level and robust substrate.

• The appliance must be raised on a wet ﬂ oor.

• Always set up the appliance isolated from the structural structure to prevent the transmission of noise and vibrations.

Danger!

• When using an open return, no appliances with an open combustion chamber may be present in the same set-up room. Strictly respect local standards with regard to the ventilation of the set-up room.

Attention!

The appliance must be level! The appliance must be set up frost-free.

4.1.5 Moving the appliance on site

The air heaters must never be moved using the corners by tilting the appliance. The housing of the appliance can be irrevocably damaged due to this. This damage is not covered by the appliance’s guarantee.

4.2 Installation of the ﬂ ue gas outlet system

4.2.1 Luchttoevoer– en rookgasafvoerleidingen

Danger!

• Protect the ﬂ ue gas outlet with a non-ﬂ amma- ble sheath if it is being guided through walls or cavities made of ﬂ ammable material. Always respect the free space of 25 mm between this sheath and the discharge pipe.

• Every Udara appliance must be equipped with an individual FGO/CAS. Shared discharge systems are not permitted.

• The burner compartment of the Udara is part of the combustion circuit. The appliance must not be put into operation with a missing front cover.

Information(s)

In some countries, the use of CAS or FGO pipes that have not been enclosed in metal or other ﬁ re- retardant material is prohibited. Always consult the local standards before installing.

Udara air heaters are appliances that, by preference, are set up as a closed appliance (type C). This means that the appliance must be connected through a parallel or concentric ﬂ ue gas outlet (FGO) and combustion air supply (CAS).

Combustion gases are discharged through one pipe and air required for the combustion is supplied through the other pipe.

IHL_UDARA_2016_11_04_BEGB

You can also set up the appliance as an open one (type B). If the appliance is set up as B22p, a special air ﬁ lter must be installed on the suction inlet of the Udara air heater. This ﬁ lter will stop the igniter ducts between the premix burners from becoming obstructed and will prevent individual objects from falling into the appliance.

Always position measuring points in the FGO and CAS so that a representative sample of the ﬂ ue gases and the combustion air can be taken. The measuring points must, by preference, be positioned as close as possible to the appliance.

The used CAS and FGO pipes must be gas-tight and must meet the applicable standards. Multicalor has PP and stainless steel pipes in its range that meet all applicable standards. If the discharge of the combustion gases and supply of combustion air takes place through the roof, the especially designed and approved icicle-low roof gland MUGRO SKYLINE must be used.

Les conduites utilisées pour l’évacuation des gaz de fumée et l’alimentation en air de combustion doivent être étanches aux gaz et respecter les normes en vigueur. Dans sa gamme, Multicalor possède des conduites en PP et en inox qui respectent toutes les normes en vigueur.

4.2.1 Type B22p connection

The combustion air is taken from the room with regard to a type B22p connection. The discharge takes place through a gas-tight ﬁ xed or ﬂ exible pipe.

Connecting to another roof gland is not permitted in relation to the approval in accordance with the Gas Appliance Directive. If the discharge of combustion gases and the supply of combustion air takes place through the wall, the especially designed and approved wall gland MUGRO WALL must be used. Connecting to another wall gland is not permitted in relation to the approval in accordance with the Gas Appliance Directive.

The ﬂ ue gas outlet must be installed with a minimum slope of 5 cm/m towards the appliance so that the condensate can ﬂ ow towards the appliance.

1 Measuring point 2 Combustion air supply opening 3 Intake ﬁ lter (dusty rooms) or protective vent

There must always be a direct and non-closable air supply outlet towards the outside with an area of 3 cm²/kW as the total set up power with a minimum of 150 cm². If local standards prescribe stricter requirements, you must, of course, comply with these. Position a protective vent or, when setting up the appliance in dusty rooms, an intake ﬁ lter on the CAS so that no individual objects can fall into the appliance and the burner is safeguarded from contaminants. Always position a measuring point in the FGO. The maximum allowable length for the discharge pipe is speciﬁ ed in table 4.2.7.

Danger!

Never connect an Udara appliance straight on to a standard chimney! A gas-tight FGO must always be used.

4.2.4 Concentric systems (C12/C32)

The ﬂ ue gas outlet (FGO) pipe is surrounded by the combustion air supply (CAS) pipe with regard to a concentric ﬂ ue gas outlet system. Multicalor carries a full range of concentric pipes.

The Y-pipe supplied with the ﬂ ue gas outlet terminal must be positioned on top of the appliance with regard to a concentric connection.

Always position a measuring point in the concentric piping, by preference, immediately after the Y-pipe or, if this is not possible, as close as possible to the appliance.

4.2.5 Chimney renovation (C92)

It is sometimes interesting to install a special ﬂ exible ﬂ ue gas outlet pipe with a diameter of 80 mm in an

existing ﬂ ue gas outlet (conventional) ﬁ replace. The combustion air can then be supplied through the air cavity between the ﬂ ue gas outlet pipe and the existing chimney or in the room itself. The connection between the ﬂ exible pipe in the old ﬂ ue gas duct and the appliance can then take place in parallel or concentrically.

4.5 Elektrische installatieDanger!

• Ensure that the installation is free from voltage (dead) before you start the installation.

• Always connect the earthing.

• Respect all applicable standards (for example, AREI (General Regulations on electrical installations)).

• Always position an external isolator switch at the appliance that will allow you to isolate the appliance from the mains.

• The minimum creepage distance between contacts must be 3 mm.

The electrical installation must always be carried out in accordance with the last publication of the relevant standards and the regulations of the local energy company.

4.4.1 Connecting the power supply

A 3-pole terminal has been installed in the fan compartment where a supplied plug can be installed for the mains power supply. A hole has been included in the housing to lead through the cable. Use the supplied blind grommet or cable coupling to lead through the cable.

Connect the cable to the 230 V~AC power supply with earthing.

We recommend connecting the appliance directly to the distribution box that has a delay fuse (the value to be used is speciﬁ ed in the technical data table).

Attention!

We recommend using circuit breakers with a D switching-off curve because of the high input surge currents of the direct current motors.

You can also connect the cable using a plug to the wall socket outlet with a socket with safety earthing if required.

The Udara must always be supplied with power. If you temporarily put the appliance out of service, the appliance can be set to the standby mode using the RC21.

4.4.2 Connecting the modulating thermostat

The Udara is used, by preference, with the RC21 thermostat for simple residential applications.

A 2-pole terminal has been installed in the fan compartment on which a supplied plug for the thermostat can be installed.

A hole has also been included in the housing to lead through the cable. Connect the thermostat through a shielded and twisted 2-core signal cable with a wire cross-section of 2 x 0.8 mm².

The box is installed at the bottom with regard to the upﬂ ow version and on top of the appliance with regard to the downﬂ ow version. The readmission ducts can also be connected directly on to the side of the air heater if required. Please order the optional ﬁ lter cartridge for a side connection to do this.

The standard side ﬁ lter frame for the Udara 40 and 50 is very small and we recommend using a long tool life ﬁ lter from the range of accessories.

If you want to use an open return (only possible if there are no appliances with an open combustion circuit in the set-up room), you can order a perforated readmission plenum.

f you are connecting an outdoor air duct, a control valve must always be included in the outdoor air duct.

Danger!

• Internal acoustic or thermal insulation in the air distribution box must be able to resist longterm increased temperatures and must be mechanically protected against being detached.

• The insulation must be erosion-proof so that no dust particles end up in the airﬂ ow.

Use the ﬁ gures below as a guideline when determining the ideal size of the air distribution boxes and/or air ducts. Please contact us for advice if you have any doubts or questions.

5 Commissioning

5.1 Switching the appliance on and off

Normally, the appliance must always be supplied with power through the mains power supply. You can follow the following steps to switch the appliance on and off during installation or maintenance.

5.1.1 Switching on

Follow the following steps to switch on the appliance:

• Switch on the mains power supply.

• Open the gas valve.

• Set the room thermostat to the required value.

• After a short waiting time, the appliance will ignite.

If the lock-out symbol is displayed on the appliance screen or an error message is displayed on the RC21 thermostat, you must unlock the appliance by pressing the reset button. You can also unlock the appliance through the RC21.

You must thoroughly vent the gas pipe before starting the appliance with regard to a new installation. A poorly vented gas pipe can mean that the appliance will be in the error mode.

If the appliance does not ignite after repeated attempts and unlocking instances, consult the section about faults and failures or contact the manufacturer or installer.

5.1.2 Switching off

Follow the following steps to switch the appliance off:

• Set the room thermostat 5°C lower than the room temperature.

• Wait until the burner has switched off (the ﬂ ame symbol will no longer be displayed on the screen).

• Close the gas valve.

• Wait until the appliance has fully cooled down (discharge air temperature < 30°C).

• Switch off the mains power supply.

5.2 Regulating the combustion

The combustion of the Udara has been set ex-factory and does not have to be changed normally. If, however, the burner management control system or the gas control block have been replaced, for example, after a fault, the calibration procedure must again be performed.

The simplest way in which to do this is through manual calibration using an RC21 thermostat. Having a device with which you can also measure the NOx (nitrogen oxide) content in the ﬂ ue gases is recommended to ensure the procedure is performed correctly.

to achieve the best possible start behaviour. This value is stored in the burner management control system and cannot be changed by the installer. Next, the heater will start to burn at maximum power

The following will be displayed on the screen:

Attention!

Ensure that sufﬁ cient vents have been opened so that the appliance can get rid of its power. If you do not do so, the overheat control will be activated and the calibration will be interrupted.

If the ﬂ ame signal is stable, “Max ok” will be displayed on the screen. Next, you can change the CO2 in the combustion gases by changing the “Combustion set” value. If you increase the value, you decrease the CO2. If you decrease the value, you increase the CO2.

If you, next, conﬁ rm the setting by pressing “Conﬁ rm”, the controller will continue to the next step.

Next, a combustion test will be performed at approximately 60% of the maximum power.

Enter the installer password to start the procedure; see the “Technical menu” page of the RC21. This password is issued when you follow training at Multicalor.

Next, select the “Calibration, manual complete” option. The appliance will attempt to start a few times until there is ﬂ ame detection. When there is ﬂ ame detection, the correct quantity of gas will be calculated

Cancel Confirm

The working method here is analogous to the previous step. The controller will complete a number of tests and, next, “Med ok” will be displayed on the screen if the combustion is stable. Here you can also change the CO2 in the combustion gases by changing the “Combustion set” value. After pressing “Conﬁ rm”, the appliance will also be tested on low power. If you again conﬁ rm this test by pressing “Conﬁ rm”, the new settings will be stored in the burner management control system.

The normal setting can be read from the table below:

Danger!

• The Udara must only be converted to propane in Belgium by an engineer appointed by the manufacturer because a new nameplate (with another gas category) must be added to the appliance.

• Never use butane (I3B) as the gas type.

The Udara can be very easily converted to be used with liquid gas (propane I3P).

It is sufﬁ cient to set the parameter TSP 9 to the value 1 and, next, perform a new calibration.

In Belgium, this conversion must be carried out by an engineer appointed by the manufacturer because a new nameplate must be added to the appliance.

±0.5%

NOx ±10 ppmCO±10 ppm

Warning!

• Most ﬂ ue gas analysing devices measure the residual oxygen in the ﬂ ue gases and calculate the CO2 based on this value. The Udara works in a vacuum (ﬂ ue gas fan after the combustion chamber) and, therefore, leaks in the combustion circuit (for example, an empty condensate trap) will lead to a dilution of the ﬂ ue gases and an incorrectly measured value. Only change the adjustment if you are sure that the combustion circuit is airtight.

• The integrity of the combustion circuit can be easily established by measuring the concentration of nitrogen oxides (NOx) in the ﬂ ue gases. When the CO2 content is 8.5, the NOx content is approximately 20 ppm (I2N). When the CO2 content is 9.6, the NOx content is approximately 20 ppm (I3P)

IHL_UDARA_2016_11_04_BEGB

6 Operating and setting

6.1 In general

Multicalor Udara air heaters are very advanced appliances where special attention has been paid to a minimum energy consumption.

The appliance is equipped with a unique patented heat exchanger made of stainless steel. The ﬂ ue gases are cooled down to produce condensate in the heat exchanger. The additional heat that is released during this process increases the efﬁ ciency of the combustion to unprecedented levels.

In addition, the power based on electricity has been signiﬁ cantly reduced by using automatically controlled fans with direct current motors. Even when the motor speed is low, the efﬁ ciency will continue to be high so that it is better for the environment and your electric bill will be lower.

The advanced burner management control system is equipped with a gas-adaptive control. This means that the ratio between the combustion air and gas is set, monitored and, if required, adjusted electronically.

Thanks to this gas-adaptive control, you will always be assured the best combustion quality even when the gas quality is not constant.

The burner management control system monitors the gas/air ratio under all conditions and will always adjust this to achieve a safe and efﬁ cient combustion.

This extremely modern control technology also ensures that the gas/air ratio can be adjusted brieﬂ y so that the appliance also ignites reliably under ice cold conditions and after long periods of being idle.

Thanks to the gas-adaptive control, the Udara appliance can reduce its capacity in a steplessly variable manner to approximately 15% of the nominal power.

This offers the best comfort in combination with a modulating room thermostat: the difference between the required and the current room temperature is measured and, based on this, the optimum power is determined to heat up the room quickly or to keep it comfortably warm.

The air quantity will be adjusted automatically to the discharge air temperature so that a pleasant indoor climate and an extremely uniform temperature is obtained.

The installer can set a low, average or high air quantity. These air quantities are linked to a low, average or high air temperature. This ensures you can have high control over the blowing characteristics of the appliance

6.2 Modulating thermostat RC21

We recommend using a Multicalor RC21 timer thermostat to drive the appliance for simple household applications.

3 4

Legend

Number Meaning

1 RC21 thermostat LCD screen 2 Operating pressure button 3 Context button A 4 Context button B

This modulating thermostat exchanges data continuously with the burner management control system so that the good operation of the appliance, the modulation degree and other appliance data of the thermostat can be read.

The thermostat allows you to remotely start the fan. You can choose whether the fan is not operational or runs at a low, average or high speed (also see item

6.6).

The thermostat also allows you to unlock the appliance if a locking fault has occurred.

The thermostat must, by preference, be connected using a twisted and shielded 2-core cable. The polarity is not important.

Pour en savoir plus, référez-vous au manuel fourni avec le thermostat.

For more information refer to the manual that is supplied with the thermostat. For demanding applications such as, for example, connecting to a building management system, the control of different zones or connecting different appliances on 1 thermostat, the standard RC21 thermostat is not suitable.

If you need this additional functionality, you can opt for thermostats from the Multicalor Verventa range that must, however, be connected through a specially shielded bus cable of the following type: JY(ST)Y-MB 2X2X0.8 mm². You can request more information about this from Multicalor.

IHL_UDARA_2016_11_04_BEGB

6.3 Air-conditioning

You can expand the appliance with cooling. A cooling unit must then be installed outside and an evaporator must be installed inside on top of the Udara air heater.

This ensures that you can distribute cold air through the ducts during the summer months.

The RC21 thermostat can be used to switch on the cooling unit.

6.4 Heat pump

You can also expand the appliance with a heat pump. You can then use the heat pump to cool in the summer and to heat in the seasons in-between.

The gas burner will then only be used if the outside is colder and the efﬁ ciency of the heat pump becomes too low or if too many thawing cycles occur.

If you want to connect a heat pump, you must opt for a thermostat of the Multicalor Verventa range. For more information please contact us free from obligation.

6.5 Operation in heating mode

The operation of the air heater can be summarised as follows in normal use:

• If there is a heat demand, the appliance will ignite the burner. The fan will be started on a minimum air ﬂ ow rate.

• The RC21 thermostat will measure the difference between the set and the current room temperature and will increase or decrease the air temperature based on this data.

• The air heater modulates the burner to achieve the set air temperature as best as it can.

• The system fan will adjust the air ﬂ ow rate to the current discharge air temperature.

The air ﬂ ow rates and air temperatures can be set by using the control panel.

The relationship between the air temperature and air speed is displayed in the above graph. If the air temperature is lower than the “low value” (3) parameter, the fan is operational at the “low” (4) speed. If the air temperature is higher than the “high value” (1) parameter, the fan is operational at the “high” (6) speed. In-between these values, the speed of the fan is automatically adjusted based on the air temperature.

The “average value” (5) and “average” (2) parameters serve as an additional checking point to ensure you have more control over the air ﬂ ow rate.

Note: only clean the burner using compressed air. The burner must never be brushed. Make sure that the heat shield in the burner does not fall out of the housing if you disassemble the entire burner.

8. Check the ﬂ ue gas outlet and the combustion air supply for leaks and dirt.

9. Clean both traps. After cleaning, reinstall and ﬁ ll with clean water.

10. Install the components in the reverse sequence, vent the gas pipe thoroughly and again switch on the mains power supply.

11. Check the gas pipe for leaks.

12. If the control is released, allow the appliance to start and, next, generate 100% heat demand using the thermostat. Ensure that the appliance can deliver the appropriate ﬂ ow rate because, if not, the appliance will modulate back. Measure the combustion values and enter them in the appliance ﬁ ring report. If the ﬂ ue gases are hotter than 50°C, check whether there is a problem with the system fan. It is also possible that the load is too high.

13. If the appliance does not start properly, check the combustion. Consult item 5.2 for more information if required. If the combustion is correct, but starting problems occur anyway, you must disassemble the burner and check the distance between the ignition electrodes and the distance from the ionisation electrode to the burner mat. The ionisation current at full load must at least amount to 7 μA.

14. If the distance between the electrodes is correct, you can perform a new automatic or manual calibration if the gas pressure matches the data on the nameplate (must only be performed by engineers who have followed training at Multicalor).

15. Check the settings of the appliance with the values listed on the maintenance card that has been stuck on the inside of the front panel.

16. Replace the air ﬁ lter.

17. Fill in the maintenance card of the appliance.

Warning!

• Replace the ionisation electrode and the ignition electrode every 5 years.

• Replace the air ﬁ lter at least once a year. Using the appliance long term without an air ﬁ lter can damage the appliance.

8 Troubleshooting

8.1 Appliance does not start after 5 attempts

Measure the ionisation current by positioning a current meter (μA) in series at the ionisation electrode and the burner management control system.

8.1.1 An ionisation current is not being formed

If you determine that an ionisation current is not being formed during the ignition phase, this points to a lack of a ﬂ ame.

Check the following:

1. Check whether the gas valve is open.

2. Check the gas pressure in the supply pipe. This

must be in accordance with the technical data.

3. Open the appliance and allow the loose ignition

electrode to spark. If a spark is not formed, you must replace the high-voltage cable, the ignition electrode or the control unit.

4. Check whether the protection shut-off valve swit-

ches by measuring the voltage.

5. Check whether gas is ﬂ owing in the protection

shut-off valve by measuring the drop in pressure over the valve during switching.

6. Remove the burner and check the distance

between the ignition electrode and the earth electrode. That must amount to approximately 3.5 or

4.0 mm.

7. The bottom side of the ignition electrode must be

at a height of 7.2 mm above the metal burner mat.

8. The bottom side of the ionisation electrode must

be at a height of 7.2 mm above the metal burner mat. If the ionisation electrode has been signiﬁ - cantly deformed, it must be replaced.

7. Check whether the double NTC (discharge air temperature) has not been exchanged with the single NTC (intake temperature).

8. Check the settings of the temperature protection by comparing the set parameters with the table in the manual.

9. Check the cabling of the NTCs to the burner management control system.

8.4 Display does not work

1. Check the power supply.

2. Check the connection of the control unit with the display.

3. Check the fuses on the interface printed circuit board system fan display.

4. Check the ﬂ at cable between the interface printed circuit board and the display.

Warning!

Pay attention to the correct connection of the ﬂ at cable. If you press this incorrectly into the connector, the display can be irreparably damaged.

8.5 Flue gas fan operates continuously or

not at all

Check the control cable (X23), if the PWM signal to the fan has been interrupted, the ﬂ ue gas fan runs at high speed. If the control cable is OK, the burner management control system or the ﬂ ue gas fan will probably be faulty.

Burner ON

Brander aanLOCKOUT

8.2 Internal error

Most “internal” errors are caused by a short-circuit in the cable loom or because of a faulty burner management control system.

Check the wiring in accordance with the ﬂ owchart and, if required, replace the burner management control system.

8.3 Overheating and NTC errors

1. Check the ﬁ lter for dirt.

2. Check whether sufﬁ cient air vents are open.

3. Check whether the ducts are sufﬁ ciently large.

4. Check the operation of the system fan and the set air ﬂ ow rates. If required, increase the set air ﬂ ow rates or lower the power of the appliance by adjusting parameter TSP 10 in the burner management control system.

5. Ensure that the appliance can blow without obstruction (especially with regard to downﬂ ow appliances).

6. Check the operation of the temperature probes. The resistance of the probes will be approximately 10 kOhm at room temperature.

If the ﬂ ue gas fan is not working despite the heat demand, check the cabling and check whether the appliance is not locked. Measure the voltage that must at least be 230 V ± 10%. Replace the ﬂ ue gas fan or burner management control system if required.

8.6 System fan operates continuously or not at all

If the fan is operational continuously, check whether the fan position is set to OFF. If this is not the case, it is normal that the fan is operational.

If the fan is not operational despite the fact that a percentage speed is being displayed on the display, ﬁ rst check the power supply voltage of the fan. If this is OK, check whether the fan can turn freely.

8.7 No communication with thermostat

Check the cabling. This must, by preference, be a shielded and twisted cable with a maximum length of 20 m for the RC21.

IHL_UDARA_2016_11_04_BEGB

8.8 Fuse or earth leakage circuit breaker intervenes

Measure the appliance to see if there has been a short-circuit. Make sure that a delay fuse has been used. The switchingoff curve must, by preference, be of the type D in view of the starting currents of the motor controls. If the earth leakage circuit breaker is of the 30 mA type, there may not be any other loads on

8.10 Service request

If it seems that the fault or failure cannot be resolved, contact the manufacturer for assistance. Keep the following data at hand:

• the appliance’s serial number;

• the gas pressure for the gas valve and type;

• measured power supply voltage;

• last appliance ﬁ ring report.

the same earth leakage circuit breaker.

8.9 Loss of ﬂ ame shortly after ignition

Check the FGO and CAS. It is likely that ﬂ ue gas recirculation takes place and the burner management control system switches off the appliance preventively because the ﬂ ame is becoming unstable.

Also check the pressure in the gas pipe and also with other consumers switched on.
