Operating principle

Forced convection for heating

Cold air from the window areas and

cooled air are drawn in and trans-

ported through the heat exchanger.

Heated air rises. Installation in front

of window areas provides a specific

shielding against cold air.

For more information, see chapter

"General information"

Forced convection for cooling

Warmed air is drawn in, cooled in

the register and discharged into the

room as cool air.

Installation in front of window areas

provides a specific shielding against

the thermal radiation due to inci-

dent solar radiation.

For more information, see chapter

"General information".

Tender specification

Version KC481 heating and cooling in 4-conductor system

Ready-to-install floor pans for the floor area. Operating prin-

ciple: Forced convection with a cross-flow fan for heating and

cooling in a 4-conductor system.

anthracite grey (RAL 7016), external, adjustable and acoustically

decoupled height adjustments (pre-installed). Condensate pan

integrated into floor pan, incl. two drain connections (Ø 15 mm)

on the sides.

Register made of copper pipes and aluminium fins, anthracite

grey (RAL7016) coated and mounted in transversal steel girder

of galvanised sheet steel, acoustically decoupled.

Cooling: Standard left to the face or room side connection with

euro taper and union nut (3/4“ internal thread) and air vent.

heat register (cross-flow fan on the window side). Protective

cover over the cross-flow fan. Cross-flow fan with energy-saving

EC motors 24 V, wired ready for connection.

Low-noise fan operation, infinitely variable via analogue

interface (0 – 10 V). Actuator control signal 24 V DC, infinitely

variable via analogue interface (0 – 10 V). Synchronised control

of fan speed and water flow for a hydraulically balanced pipe

system and especially energy-efficient operation while maintai-

ning a minimum spread between flow and return temperature.

Factory configuration of appropriate control algorithm.

Aluminium roll-up grille as standard. Acoustic decoupling

through placement of the aluminium roll-up grille on rubber

elements in the floor pan. Consisting of sturdy lengthwise pro-

file bars, natural colour anodised, with profile bar dimensions

of 20 x 6 mm. .Grille with a total height of 20 mm and an open

cross-section of 70%.

Control system

Control systemIn the course of converting from AC to EC technology for the

Ascotherm eco fan motors, a powerful and innovative control

system was developed. The new Ascotherm eco control system

conforms to the growing demands for both modern single-room

control and connection to a building management system via a

KNX BUS.

Attention was also payed to ensure easy installation during de-

velopment of the control system. The control board is compatible

with all Ascotherm eco trench convectors having EC cross-flow

fans (KRN81, KC281, KC481) and already installed at the factory

in a casing with protection class IP65. The installed electrical

components are already completely wired and thus ready for

connection upon arrival from the factory. Customer-specific

upgrades of the system in the form of various signal inputs and

outputs (plug-in contacts) are possible at any time.

Electrical connection

In a standard situation, only the mains supply (220-240 V AC, con-

ductor cross-section of at least 1,5 mm²) and the communication

line to the Ascotherm eco room thermostat (wire cross-section

0,25 mm², twisted-pair conductors, max. permissible line length

30 m) need to be connected on site.

Depending on the configuration and type of optional control

components, the following additional external connections can

be provided on-site:

• Internal bus line to additional convectors in a combined

control system (up to 6 convectors), wire cross-section at least

0,25 mm², max. permissible line length 100 m

• Bus line to a higher-level building management system, wire

cross-section at least 0,25 mm², max. Permissible line going

700 m between Ascotherm eco with KNX plug-in card and IP

router

• Line connection to an external room temperature sensor

• Line connection to an RF receiver (for receiving input signals

from window contact sensors and presence detectors)

The following optional control components are wired inside the

floor pan.

Connection can be made at the factory (with a corresponding

order) or by the installer:

• Thermoelectric actuator 24 V DC, control voltage 0-10 V DC

• Surface sensor for flow temperatures (possible for heating

and cooling circuits on the KC481)

• Dew point sensor (KC281 and KC481)

• KNX plug-in card

For more detailed information about electrical connections, see

the electrical installation instruction.

Commissioning

Every Ascotherm eco trench convector is supplied with all control

parameters preset at the factory. Depending on the situation

(e.g. control with or without a building management system),

convector type and individual needs of the customer, control sys-

tem parameters can be set during commissioning with the aid of

an Ascotherm eco room thermostat (see accessory ZE00770003).

Control characteristics / functional overview

• Infinitely variable control of the fan speed in relation to the

room's heat requirement (difference between set tempera-

ture and room temperature)

• Synchronised control of fan speed and valve stroke (water

flow) for a hydraulically balanced pipe system and especial-

ly energy-efficient operation (maintenance of a minimum

spread between flow and return temperature). According to a

preliminary study conducted by Prof. Dr.-Ing. Rainer Hirsch-

berg, University of Aachen, this can save 8% of the thermal

energy and more than 80% of the electrical energy (recircula-

tion) compared to systems without synchronised control.

Control system

• In a combined control system, control based on several room

temperatures (sensing via external room temperature sensors

– optional accessory) is possible

• even greater energy efficiency possible through optional ac-

cessory incorporation of window contact sensors and presence

detectors into the control system (both wireless)

• automatic changeover in the 2-pipe cooling mode through

installation of flow temperature sensors (accessory)

Connection sets for the Ascotherm ecoIt is recommended that the Ascotherm eco be fitted with preset

kv connection sets (see accessories range). On request, the instal-

lation can be done at the factory.

The Ascotherm eco units are fitted with preset connection sets

depending on the heating or cooling capacity.

Ascotherm eco units can also be fitted with the fine-adjusting

valve. The adjustable valve insert permits reproducible settings of

low water flow rates. The setting values can be taken from the

diagram.

1) Dimensions characteristic |MT| and ordering code need to be stated when ordering (for description, see chapter "General informati-on" and colour chart)

Top grilles

are attractively shaped, solid and robust. There are practically

no limits to how they can be integrated into the architectural

design of the room, thanks to the choice of various profile forms,

materials and

Surface finishes. The grilles can easily be removed for cleaning

and then returned to their original positions.

• periodic or extended draining of the system

• operation with steam

• addition of substances (e.g. chemicals, antifreeze) to the

heating water that can have a corrosive effect on copper or

sealing materials

• excessive sludge deposition in the trench convector

• occasional or constant drag-in of oxygen into the system (e.g.

lines and pipes that are not sealed against diffusion)

• leaks in the heating system

Special versions according to drawings

If necessary, the customer receives a dimensional drawing for

review and approval; the order will be produced after this is

returned. In the event that the order is cancelled, the customer

must pay compensation for the services and costs incurred up to

that point.

Paint finishes

Stoved enamel powder coating (packaged) in all RAL colours

according to customer specifications; colour deviations customary

in the industry are possible.

Use only original RAL colour samples for colour matching.

For production reasons, paint finishes are subject to slight colour

deviations, caused in part by specific light conditions. There

may also be differences when comparing painted surfaces with

painted ceramic products. Because of limitations in the printing

process, the illustrated colours are not binding.

The floor pans and possibly aluminium grilles are finished in

accordance with DIN 55900. They must be transported with care

and protected against damage at the construction site.

Noises

Noise emission depends on the design, size and fan speed. The

acoustic power levels were measured using DIN 45635-1 as a

reference.

According to E DIN EN 16430-1 (Fan-assisted radiators, convectors

and trench convectors - Part 1: Technical specifications and requi-

rements), the sound pressure level can be defined with a room

absorption of 8 dB(A). This corresponds to a distance of 2 m from

the tested unit, a room volume of 100 m3 and a reverberation

time of 0,5 s.

The acoustic characteristics of the room influence the noise level.

Accordingly, the actual values may differ. It is recommended that

the Ascotherm eco be designed for operation at a moderate

speed.

Acoustic

Sources of noise cause the air to oscillate; it compresses and

expands alternately.

These pressure changes dither the existing air pressure and pro-

pagated through the air in sinusoidal form. When these pressure

fluctuations reach our ear, the air pressure waves are transfor-

med into mechanical vibrations by the eardrum.

The process of hearing is begun.

The human ear only senses the airborne sound; the following

two factors are decisive:

a: Sound pressure

b: Frequency

1. Sound pressure

The sound pressure is the change in pressure of the air caused by

a sound source. These pressure fluctuations are measured in N/

m², and are designated with the letter p.

The sound pressure is a measure of the sound level. It depends

on the distance between the sound source and the measurement

location as well as the properties of the room.

The sound pressure is unsuitable for calculating the expansion of

sound on the sound propagation paths. For this it is necessary to

determine the acoustic power of the sound source.

2. Acoustic power

The energy converted into sound by a component (sound source)

is called acoustic power. This acoustic power is transmitted to the

air in the form of pressure fluctuations.

The acoustic power is a value that cannot be measured directly. It

is determined by integrating the acoustic pressure over a hemis-

pherical or spherical surface about the sound source.

The acoustic power is thus a value that is independent of space

and distance.

It will be used for all of the following calculations.

The acoustic power is stated in watt [W].

For practical use, dimensionless figures have been introduced

based on the work of A. G. Bell.

3. Sound pressure level

The logarithmic relationship of a sound pressure p to the refe-

rence value p0 is designated acoustic pressure level LP; the unit

used to specify it is the decibel [dB].

Lp = 10 lg ( p )2

p0

p = Effective value of the sound pressure at a certain

spot in the room

p0 = Reference sound pressure, specified internationally at 2 x

10-5 N/m²

4. Acoustic power level

The acoustic power level LW is defined by:

LW = 10 lg ( P ) in dBP0

P = Acoustic power in watts

P0 = Reference power, specify internationally at 1 x 10-12 watts

The sound pressure level is the sound generated at the sound

source (the energy transmitted to the air), while the acoustic

pressure level is the sound registered at a certain distance from

the sound source.

Thus generally the acoustic power level is larger than the

acoustic pressure level.

5. Frequency assessment

Humans perceive the same sound pressure level differently at dif-

ferent frequencies. A sound pressure level is generally perceived

as quieter and less annoying at low frequencies than at higher

frequencies.

In order to take this subjective perception into account, the

objectively measured sound pressure levels are adapted to the

perception of sound levels. This is called assessment of the sound

pressure level.

This assessment is done by subtracting a certain amount from

the measured sound pressure level for frequencies that humans

are less sensitive to, while adding a certain amount in the other

frequency ranges.

Of the various assessments, the A-weighting has become virtually

the only one used.

This provides information in the form of a single figure that is

designated as an A-weighted acoustic pressure level or an A-

weighted sound pressure power.

The unit is called db[A].

6. Sound level additions

If several sound sources are present, then the corresponding

levels have to be added to form a total sound level.

The same principles apply here for both the sound pressure level

and the acoustic power level.

When there is more than one sound source with the same level,

the following relationship applies:

Ltot = L1 + 10 x log n [dB]

Calculation: General informationCalculation of the heating requirements of buildings is perfor-

Basic principles heat outputsThe heat outputs of Ascotherm eco trench convectors were

measured and established in accordance with E DIN EN 16430

"Fan-assisted radiators, convectors and trench convectors" Part

1: "Technical specifications and requirements" and Part 2 "Test

method and rating for thermal output".

Standard heat output ΦS (∆T = 50 K)

The standard heat output ΦS in watts of a radiator indicates the

heat flow that is emitted under the following conditions:

- Flow temperature t1 = 75 °C

- Return temperature t2 = 65 °C

- Room temperature tr = 20 °C

- Air pressure p = 1013 hPa

From this follows the average heating water temperature tm in

°C.

put is calculated as follows:

Φ = ΦS x∆T

or Φ = ΦS x CK∆Tn

where n = exponent and CK = correction factor of the heat

output characteristic curve (see technical data of the radiators).

Planning, assembly and installation information, cooling outputs


Calculation: General informationThe cooling load of buildings is calculated on the basis of

VDI 2078.

Basic principles, cooling outputsThe cooling outputs of Ascotherm eco trench convectors were

measured and established in accordance with E DIN EN 16430

"Fan-assisted radiators, convectors and trench convectors" Part

1: "Technical specifications and requirements" and Part 3 "Test

method and rating for cooling outputs".

Standard cooling output PKN (∆T = 10 K)

The cold air flow generated under the following conditions is

designated the total standard cooling output PKN in watts of an

Ascotherm eco:

t1 [°C] = Cool water inflow t1 = 16 °C

t2 [°C] = Cool water outflow t2 = 18 °C

tr [°C] = Room temperature tr = 27 °C

Air pressure p = 1013 hPa

Relative humidity ϕ = 50 %

This produces the average cooling water temperature tm in °C.

tm =t1 + t2

Cooling output PK (when deviating from ∆T = 10 K)

For temperature loss ∆T that deviate from ∆T = 10 K, the cooling

output is calculated as follows:

PK = PKN x∆T

or PK = PKN x CK∆Tn

where n = exponent and CK = correction factor of the heat out-

Note regarding "Basics of cooling outputs":

The calculations above are for a dimensioning with dry cooling.

If system parameters that result in condensation on the cooling

register are intentionally selected during planning, the sensible

cooling output needs to be considered in addition to the total

cooling output. In this case, the sensible cooling output is the

determining factor for performance the cooling load.

Example of system dimensioning under normal conditions

Dew point tableFor a correct dry cooling dimensioning without condensation,

the flow temperature of the cool water needs to be taken into

account. The flow temperature of the cooling water can be

taken as the lowest possible surface temperature of fin compon-

ents. Assuming normal conditions (room air temperature 27 °C,

relative humidity 50%), the

dew point will be 15.8 °C. This means that condensation can be

expected if the flow temperature of the cool water drops below

15.8 °C. Beneficial drying effects associated with fan operation

are not taken into account, since this effect depends largely on

the fan speed.

Planning, assembly and installation instructions

Scope of delivery• External, adjustable and acoustically decoupled height adjust-

ments (pre-installed)

• For KRP91, KRN92 and KRN81 aluminium linear grille (on

request, delivery can be postponed until the end of the

construction phase)

• For KC281 and KC481 aluminium roll-up grille (on request,

delivery can be postponed until the end of the construction

phase)

• Plastic elements for acoustic decoupling

• Installation cover and edge bar protection (for protection

during the construction phase)

Planning advices• To compensate for cold air that occurs on large window areas,

the trench convectors must be dimensioned to extend along

the entire length of the window.

• The thermal behaviour of screeds and floors can compress the

floor pans of trench convectors. To prevent this, expansion

joints must be provided.

• When electrical cables or a thermostatic sensor head with a

remote sensor will be used, it is necessary to install an empty

conduit.

• The installation cover supplied serves to protect the convec-

tor during the construction phase and should be replaced

with the supplied linear grille or roll-up grille only after all

construction work has been completed. The installation cover

has only limited loading capability and is not suitable for use

as a surface to support scaffolds, ladders etc.

• The convector must be accessible for maintenance work at

any time.

Installation instructions

Positioning and arrangement

• Remove the packaging film and packaging cardboard from

the trench convector before installation. If the top grille

has already been delivered, store it in a safe location until

construction work has been completed.

• Place the trench convector in position and use the external

height adjustments to align it. The height adjustments can be

placed in the correct position with the aid of a screwdriver.

• Use the mounting brackets to secure the floor pan to the

floor.

• If necessary, use insulation underneath and on the sides of the

floor pan as well.

• Note the acoustic decoupling

Connecting of the trench convector

• Water connection to the face (as standard) or room sided with

openings already provided for pipe entry (on request, other

connection arrangements also possible).

• Attach fittings and connect convector to pipework.

• To prevent entry of screed into the floor pan, seal the provi-

ded openings with suitable material. (e. g. plastic plugs from

the accessory range)

• Perform a pressure test.

• Cover the convector with the supplied installation cover for

protection

• When components from other manufacturers are used (e.g.

connection set, actuator,…) that are not in the accessory

range for the Ascotherm eco, pay attention to the installation

dimensions.

Intended use

The Ascotherm KRN81, KC281 and KC481 are intended exclusi-

vely for use in indoor areas (e.g. conservatories, residential and

commercial areas, showrooms, etc. The Ascotherm KRN81, KC281

and KC481 cannot be used in swimming pools, damp locations

and outdoor areas. In case of doubt, always consult the manufac-

turer. Any other or additional use shall be considered as impro-

per use.

Safety instructions

• Electrical work may be carried out only by authorised electri-

cians. Connection must comply with valid VDE regulations and

the EVU directives.

• When installing Ascotherm KRN81, KC281 and KC481, a suita-

ble residual current-operated protective device (RCD) / earth

leakage circuit breaker (less than or equal to 30 mA) must be

installed.

• In case of failure to comply with the regulations and directives

malfunctions with consequential damage and endangerment

of individuals can occur. Mixing up wires or connecting impro-

perly can result in MORTAL DANGER!

• Note additional safety information in the installation instruc-

tions.
