Product Description

AEROTOP T

High Degree of Efficiency and Optimized Defrosting

Thanks to the correspondingly dimensioned air heat exchanger as well as the unique defrosting system, the AEROTOP T heat pump is especially efficient and a cost-saver. This heat pump always exceeds the required degree of efficiency (coefficient) of3.0 (COP at A2W35). Frost forms on the air exchanger, the evaporator, if the exterior temperature is less than 5°C. This results in ice formation and as a consequence reduces the heat exchange and with that the efficiency of the heat pump. The evaporator must be defrosted to remove this frost or ice. However, the defrosting process, carried out by the AEROTOP T by reversing the cooling circuit, is cumbersome since the heat pump does not yield any energy during the defrosting process but still uses electricity. This is frequently unnecessary since frost formation depends on the humidity in the air. Instead of the unnecessary defrosting at timed intervals, the AEROTOP T determines the correct time to defrost the unit using a progressive and well thought out logic with different performance parameters in the cooling circuit. Thanks to this procedure, the unit rarely requires any defrosting during the winter, if any at all, which is a great advantage.

Cooling with AEROTOP TR

The purpose of heat pumps is primarily to supply a building with heat. However, the technology can also be used to cool a building in the summer. This involves actively generating the cooling energy through a process reversal of the heat pump. In case of distributor systems specifically designed for cooling (fan coil or similar), the cooling capacity of the heat pump can be transferred optimally to the building. Cooling ceilings also have a good cooling capacity and comfort level. Floor heaters, however, are only partially suited and provide a limited cooling effect. Radiator heaters are unsuitable.

Cascade

Thanks to the new heat pump controller LOGON B WP61, it is possible to link and operate several heat generators of a system in a cascade arrangement. Cascades with up to 4 heat pumps, or a bivalent operation in combination with fossil heat generators are feasible. When using a cascade formation, the heat generators switch on or off depending on the current energy demand: If the currently running heat pump cannot satisfy the energy demand within a specific time, an additional heat pump/heat generator switches on.

Quiet Operation

Regardless whether installed indoors or outdoors, the air-water heat pump AEROTOP T is characterized by comparatively very low noise emissions. This is possible thanks to the high-performance fan, the very advantageous air routing, the noise--dampening insulation of the cladding, as well as the multi-dampened support of the cooling circuit. Additional noise insulation elements are available for most variants to reduce sound emissions further. AEROTOP T heat pumps are quiet and efficient. However, incorrectly integrating constructional components may result in undesired noise increases if the conditions are unfavorable.

Flexible and Space-Saving

Thanks to the clever utilization of the geometric properties of the radial fan, AEROTOP T heat pumps are among the most flexible, space saving air--water heat pumps. Especially noteworthy is the fact that the heat pump can be placed into the left or right corner of the utility room when not using the air ducts. The exhaust opening is easily moved on-site from the left to the right and even to the top without having to use any additional tools. The intake openi selected as desired without special accessories. AEROTOP T heat pumps are also suitable for outdoors installation when using the corresponding accessories.

Enclosure and Special Components

The enclosure consists of a frame that is completely free of thermal bridging, sound dampened, and specifically developed for use with heat pumps. The cladding and panels feature a high-grade insulation to sound-dampen and thermally insulate the unit. A pedestal or base is not required since the feet of the unit feature a vibrationdampening design. All panels can be detached for easy access to the internal elements of the unit and for control or configuration tasks.

The high-performance radial fan ensures the unit runs efficiently and quietly. The high performance cooling circuit is mounted on a vibrationdampened support and features a thermostatic expansion valve, filter dryer, inspection glass, high-pressure pressure controller with manual reset, and a low-pressure pressure controller with automatic reset function. The hermetic scroll compressor is mounted on a double vibration dampened s upport. The evaporator consists of a large-area finned tube heat exchanger made from aluminum and copper; the condenser consists of a welded chromium steel high performance plate heat exchanger. The environmentally friendly refrigerant R407C is used as the working medium. A flow monitor on the consumer side ensures trouble-free cooling for reversible heat pumps.

Heat Demand and Heat Capacity

The correct dimensioning of the air-water pump is a key task. The heat pump must meet the heat demand of the building. This demand increases as the exterior temperature drops but the heat capacity of the air-water heat pump decreases at the same time. The two charts illustrate this opposing trend.

Correct Dimensioning and Bivalence Point

This makes it clear that a monovalent system with an air-water heat pump as the only heat generator has a clearly overdimensioned heat pump during most of the year and especially during the intermediate season. Not only does this result in higher investments costs, the more frequent switching (on, off) of the heat pump also has a negative effect on the pump's efficiency and thereby increases operating costs (see chart A).

A somewhat smaller heat pump is selected for a bivalent system. This pump is dimensioned not for the exterior design temperature of the system but a slightly higher exterior temperature instead, the so-called bivalence point. If the exterior temperature drops below the bivalence point, an electrical auxiliary heater is switched on, this then covers the missing heat output. The heat pump continues to have priority and, together with the additionally activated electrical heater, delivers the required heat (see chart B).

With a bivalence point, the heat pump is dimensioned exactly to meet the heat demand of the building. With lower exterior temperatures, the electrical auxiliary heater is activated; with higher exterior temperatures, the heat pump is still overdimensioned but to a lesser degree. An optimal annual degree of efficiency (coefficient) is achieved if the bivalence point is set to be slightly below the temperature most frequently occurring at the building location.

Operating Limits

General Information

The rated throughput values for evaporator and condenser are minimum values. Set points and adjusted parameters may not fall below these values to ensure the indicated performance.

Pipes, tubes, and air ducts must be kept as short as possible and routed in such a way that pressure and heat loss are minimized. Incorrectly or badly installed or dimensioned pipes, tubes, or air ducts may damage the heat pump.

Area of Application

The following chart depicts the application area of the air-water heat pump AEROTOP T. Please consult the performance overview for more detailed operating specifications for various heat pump models. The temperature difference at the condenser must be between 7 and 10°C.

Planning Notes

Cooling with Heat Pump Systems

Active Cooling

The cooling energy is produced actively using the heat pump to cool. The purpose of heat pumps is primarily to supply a building with heat. However, the technology can also be used to cool a building in the summer. This requires a process reversal during the cooling cycle. In this case, the heat emission side (condenser) becomes the heat absorption side (evaporator). During this phase, the heat pump functions like a refrigerator. The cooling and heating cycle cannot run at the same time. The use of a cool store is recommended in any case to prevent the heat pump from switching on and off and switching to water heating too often. Depending on the system concept, the heating storage can also be used as cooling storage. In case of distributor systems specifically designed for cooling (fan coil orsimilar), the cooling capacity of the heat pump can be transferred optimally to the building. Cooling ceilings also have a good cooling capacity and comfort level. Floor heaters, however, are only partially suited and provide a limited cooling effect. Radiator heaters are unsuitable.

Active Cooling Insulation

Water at a temperature less than 17°C is considered to be cold water. In the presence of cold water, the usual heating system insulations cannot be used. Suitable insulation, especially when using active cooling, is necessary. Insulation suitable for cold water is primarily used to avoid condensation but also to prevent cold water absorbing any of the heat, and also to protect against external mechanical stresses. Condensation must be avoided with a suitable insulation to prevent surface corrosions on the distributor system or mold in moist layers.

Insulation for cold water must be vapor-- proof and installed to all distributor system elements (pipes, tanks, pumps, cocks, valves, etc.) in a vapor-proof manner. Special insulating materials are commercially available in different designs (e.g. Armaflex, Tubolit). Standards SIA 380, DIN 4140 describe the insulation techniques. Please comply with the guidelines of relevant local professional associations (VSI, VDI, FESI).

General Cooling Information

1. The cooling cycle always must be monitored. If the room air is cooled unchecked, condensation water will emerge. This may damage the equipment or building components. The flow temperature in conjunction with the humidity (dew point contact temperature detector or room sensor for humidity and tempera ture) is best for monitoring.

2. A separate cooling circuit should be planned for the cooling mode. This circuit can be combined with a cooling ceiling or ventilation system, for example. Partial cooling via the floor heater or convectors is also possible if the need for cooling is limited.

3. Water flow must be ensured or cooling is not possible. When cooling via the heating surfaces, thermostatic individual controls must be used that can be switched to cooling mode. The valves are otherwise closed in summer and cooling is impossible.

Measures to Reduce the Building Cooling Capacity

The room cooling capacity is calculated based on the sum of the individual room demand. If the cooling demand exceeds the available cooling capacity, the following reduction measures may be used:

1. Direct sunlight through the window areas can be restricted through constructional measures (shutters, window shades, blinds).

2. The amount of sunlight received by each room frequently differs due to the different cardinal points.

is means that not the entire

Th cooling capacity must be available at the same time. This can reduce the max. simultaneous cooling demand.

3. Nighttime cooling of constructional elements can also lower the daytime cooling demand.

Calculating the Cooling Capacity

The cooling demand is calculated in accordance with national and local standards. E.G.: VDI 2078 : Real estate and buildings DIN 18599: Energetic assessment of nonresidential buildings (also includes air-conditioning or cooling) DIN EN ISO 13790 Energetic assessment of buildings (similar to DIN 18599) only across Europe DIN EN 255 SIA382/2: Room temperature requirements. SIA382/3: Determining the cooling requirement of building.

Cooling is differentiated by internal cooling capacity (e.g. thermal discharge of equipment, persons, lights) and external cooling capacity (sun exposure, heat from building components, and ventilation gains due to exterior air). The estimate acc. to HEA can be used for approximate calculations. However, the conditions listed below must be taken into account as well. The calculations of the implementation phase must be based on national and local standards.

Planning Notes

Cooling with Heat Pump Systems

Comfortable Room Temperature

A room is considered to be thermally comfortable when the room temperature in the summer is below 28°C. This does not apply to air-conditioned rooms. Other factors are affecting thermal comfort ranges as well. Thermal comfort requirements are defined in standard DIN EN 15251, which provides a general guideline when implementing construction projects.

Recommendations for Surface Temperatures of Cooled Floors

When using a floor area for cooling, the comfort requirements and the weather data can be used to estimate the condensation risk so that the surface temperatures should generally be in a range of 20°C to 29°C. Special attention must be paid to floor surfaces that are used when barefoot, for example, in bathrooms, since the surface temperatures perceived as being comfortable may be significantly higher depending on the floor covering. Rooms with high humidity loads, especially bathrooms and kitchens, should not be cooled or only by considering the dew point threshold.

Monitoring Function to Prevent Condensate Precipitation

To avoid condensation, the integrated Logon B WP61 controller features different monitor functions.

1. Flow Temperature Monitor

The temperature is set at the factory to 18°C. This temperature value ensures in almost all cases that condensation does not occur. A dew point monitor should always be used in addition.

2. Dew Point Monitor

This device is attached to critical points such as the floor heating distribution box. As soon as the connected dew point monitor detects condensation, it closes the contact and thereby switches cooling off.

3. Hygrostat

To prevent condensate due to a room humidity that is too high, a hygrostat can be connected, which then realizes a fixed flow temperature increase. As soon as the value set at the hygrostat is exceeded, the hygrostat closes the contact and this triggers the flow temperature set point increase set here.

High-End Solutions

4. Humidistat

To prevent condensate due to a room humidity that is too high, a humidistat can be connected, which then realizes a continuous flow set point increase. If the relative room humidity exceeds an adjustable value, the flow set point is increased steadily.

5. Room Sensor for Humidity and Temperature

The dew point temperature is determined based on the relative room humidity and the associated room air temperature. To prevent water condensation on surfaces, the flow temperature is min. limited by an adjustable value that is above the dew point temperature.

Compact Heat Pump Water Heat Exchanger Pressure Loss

The thermal mixing valve integrated into the compact heat pump routes a part of the flow water back to the accumulation tank at flow temperatures below +30°C. This way the storage tank is heated immediately and the energy depot is available for the defrosting of the evaporator. This upholding function ensures a continuous defrosting process and the system can be operated even when the heating system is cold.

Settings of the Integrated Thermal Mixing Valve of the Compact Heat Pumps

Important: Already provided with factory settings and NORMALLY does not require readjustment.

- AEROTOP T07C (Manually adjustable valve with scale): The factory setting of this valve is set to the minimum (scale at 0) = crank completely closed! (Important: The mark for making adjustments is located on the rear of the valve; use handheld mirror)

- AEROTOP T10-12C (Not manually adjustable, must use key to change settings): Correct adjustment is as follows: Open completely and then turn back 3.5 turns.

Checklist

Correct Installation of an Air-Water Heat Pump

AEROTOP T heat pumps are quiet and efficient. However, incorrectly integrating constructional components may result in undesired noise increases if the conditions are unfavorable. A careful assessment of the noise emissions is required when planning the installation of heat pump systems.

To be considered when installing an air-water heat pump

Each reflecting surface doubles the noise (acoustic power). One wall increases this value by +3dB, one corner by +6dB.

Rooms with reverberant or sound-reflecting floor coverings and walls increase the noise level.

Be careful with dropping the washing

Adherence with the min. clearances reduces noise reflection and air short-circuits and improves airflow near the fan.

Construction measures can reduce noise, plants cannot.

Noise reduction measures considered early on in the development process result in the fewest additional costs. Subsequent measures usually are extremely expensive and cumbersome to implement. [Heat Pump Manual, Federal Energy Agency, Switzerland] The following points apply to the interior and exterior installation of air-water heat pumps.

one corner by +6dB. Avoid solid-borne noise transmission by avoiding reflecting surfaces. Never route air intake or outlet into closed or partially closed spaces such as a corner, foyer, entrance area, covered patio, etc.

Avoid rooms with reverberant or sound-reflecting floor coverings and walls. When installing the heat pump in a room with reverberant or sound-reflecting floor coverings and walls, reflections may increase the sound level. Cover one or two walls with noise-absorbing material if this is the case.

Dropping the washing from lived-in rooms to the place of installation of the heat pump can lead to noise transmission when unfavourably positioned.

Make sure the min. distances and clearances to the air intake and outlet as well as the min. size of the light wells are applied. Avoid walls or flow barriers around the circumference of the heat pump to ensure air can reach the fan evenly. Less pressure losses = low peripheral speed = reduction of the fan noise.

Use constructional measures to interrupt the flow of noise from the heat pump (direct noise propagation). Use solid walls, fences, palisades, etc. to reduce noise levels. Plants, however, do not reduce noise.

Consider different noise sensitivity levels.

Sound absorbing materials reduce noise.

Separation from the structure minimizes structure-borne sounds.

Correct installation of pedestal or base reduces structure-borne sounds.

Correct installation of the ducts reduces air and structure-borne noise transference.

Avoid air short-circuits and airflow barriers.

Always comply with all rules, regulations, and applicable laws.

Avoid placing the heat pump where it may cause problems due to its noise emission (bedrooms, living rooms, neighbors, etc.). Position heat pumps in areas where noise is less likely to be an annoyance. If installed indoors, do not install underneath or next to living or sleeping quarters.

Additional sound absorbing materials or measures must be planned for and used in cases where extreme noise reductions are desired or when installing model Forever GREEN 20C or later. Use only original accessories and spare parts. in extreme cases, it may be advisable to consult a noise expert.

Always use flexible connections throughout: Flexible hoses and tubes for heat distribution, flexible electrical connections, sound isolation of the air ducts by using elastic sleeves or Compriband products.

The base or ground must be level or made level and able to support the load of the equipment. Use the adjustable feet of the heat pump to level the equipment after installation.

All wall openings and ducts must be equipped with the corresponding noise-absorbing materials. Comply with the specified cross-sections and dimensions.

Air intakes and outlets cannot be installed next to each other without using a separating wall. Avoid any airflow obstacles that favor an air short-circuit.

Setup and Connection Instructions

Safety, Transport and Installation

Safety Information

• Compliance with all rules and

instructions of all documentation, labels, type plates, and associated documents of the unit is mandatory.

Transport

• When receiving the shipment, the

heat pump must be checked for completeness as per order confirmation .In case of damaged or missing material, the carrier must be informed in writing immediately.

• Care and due diligence are

required during transport, setup, preparation, or when handling heavy materials that may damage the heat pump.

• Make sure that towing ropes, belts,

or chains used for transport or installation do not damage the heat pump. Do not allow the heat pump to swing back and forth when lifting it up. Never tilt the heat pump more than 15° from its vertical axis.

• The heat pump is affixed to a pallet

at the factory for transport and covered with a protective film to protect the unit from scratches. Do not remove the packaging until the heat pump is positioned at its final location.

Setup

• Setup must be carried out carefully

and accurately.

• AEROTOP T heat pumps can be

installed on a level interior floor without pedestal or base. If installed outdoors, a pedestal or base is required unless the substrate is very firm and can support the load.

• The installation room must have at

least one exterior wall. Rooms with high humidity are unsuitable as installation locations for AEROTOP T heat pumps. A condensate drain must be available.

• The heat pump must be set up on

a level ground and aligned with the adjustable feet. Make sure there is sufficient space to access the control panel and at the sides for inspections and maintenance.

• Make sure the ground is able to

support the load of the heat pump and all accessories. The floor or ground must be free of dust and other foreign particles. If installing in the basement, make sure the selected installation position cannot be flooded.

• The heat pumps may not be placed

on floating floorings.

• Once moved to its final location,

the heat pump must be carefully unpacked and removed from the pallet. Protect heat pump from impact and other damaging forces!

Installation

• The safety regulations and

schemes/diagrams must be strictly observed.

• The accessories and additional

equipment must be installed by a trained service technician (heating contractor) as per the enclosed assembly and installation instructions.

• The noise emissions of the

AEROTOP T heat pump are very low thanks to the sound-absorbing materials used to mount the mobile parts and the insulating cladding. The effective noise value depends also on the size of the installation room, the noise-absorbance or reflection of the materials in the room, as well as the possibility of the noise to spread and transfer via solid bodies, among others.

• Air ducts, pipes, and electrical lines

must be attached to the masonry and not the heat pump.

• All of these connections must be

established using flexible connections so that they can swing freely, especially when the compressor or evaporator starts up. Only then is it possible to avoid transference of sound from solid bodies to the building structure as well as line breakages.

Observe the checklist notes when selecting the installation site for the correct setup of an air-water heat pump

Setup and Connection Instructions

Electrical Connections, Installation Types, Hydraulic Connections, Condensate Drain

Electrical Connections and Control Information

The electrical connections must be established in compliance with local rules and regulations. The current feed may exhibit a max. tolerance of 2% with this power intensity when a voltage of 10% exists. Do not connect the heat pump if the phase difference exceeds more than 2%. Operating the equipment outside of the listed limit values will void the warranty. If necessary, please contact your local electricity company or utility. The internal wiring of the heat pump is carried out at the factory as listed on the electrical diagram included with the unit. The heat pump is equipped with an electrical supply box containing the components listed below.

• Heat pumps and system controller

unit

• Elements to feed the

corresponding components of the heat pump.

An automatic cutout switch or a 3 phase, slow-blow fuse with neutral conductor must be provided externally in compliance with the technical requirements of this documentation. The low voltage cables (control) may not be placed in the same cable c onduits or ducts as the supply cables. The exterior temperature sensor of the controller must be attached to the outside wall of the building in a location protected from the afternoon sun and other heat sources (open windows, chimneys, etc.). Northern and northeastern exposures are preferred. If the room impact is to be activated for a remote control, this control unit must be placed in a reference room (e.g. living room) where it cannot be influenced by an external heat source (e.g. stoves, heaters, air flow, etc.).

Indoor Installation

If installed indoors, AEROTOP T heat pumps do not require base or pedestal.

All heat pump models T20 – T35 must be equipped with noise dampers for air intake and air outlet.

Outdoor Installation

If the heat pump AEROTOP is installed outdoors, the heating pipes and ducts must be as short as possible and they must be well insulated. Place the heat pump on a level and solid surface with the necessary bearing capacity. The corresponding accessories needed for the outdoor installation must be ordered as well.

Heating System Hydraulic Connections

AEROTOP T heat pumps can be connected in any desired layout. The hydraulic connections require flexible ducts to avoid noise transference from pipe openings and solid bodies to the distributor network and from there to the heating elements such as radiators, etc. The ducts can be directed from the right or left and are connected to the inside of the heat pump.

The ductwork must be carried out in such a way that pressure drops at the nominal volume flow do not exceed the available pressure since this would result in a reduction of the heat pump output.

This means that ducts cannot have elbows that are too narrow.

Pipes and du insulated to prevent unnecessary heat loss and the formation of condensate, which could damage the pipe and duct system or the installation location.

cts must also be sufficient

For each heat pump we offer hydraulic standard schemes. The integration of these variants guarantee a safe and faultless operation.

The system must be thoroughly flushed before connecting to the heat pump.

Residues in the heat pipes lead to damages on the heat exchangers und to malfunction of the heat pump. Especially if there is no buffer storage it is recommended to a dirt trap in the heating return flow.

The water filled into the heating system must be handled in accordance with the rules and regulations of the relevant professional associations.

It is important to ventilate the heating system. If not the correct operation of the heat pump is affected. Therefore an exhauster must be provided. The compact heat pumps have an exhauster installed in the flow.

Condensate Drain

The condensate drain should be as close to the heat pump connection as possible. To prevent room air or c analization waste air from being sucked into the heat pump, the condensate drain must be connected airtight to the heat pump using a siphon with a min. height of 100 mm. The condensate drainage pipe cross-section may not be reduced and must be at a continuous 2% incline to ensure water can be ufficiently drained.

34

Commissioning

Conditions, parameterization, maintenance

Requirements for Initial Startup (Commissioning)

The initial startup of the AEROTOP T heat pump must be carried out by our qualified technicians or the warranty will become void.

Operating the heat pump is prohibited if the following conditions exist::

• Construction drying

• System/unit used in unfinished

buildings

• Windows or exterior doors

unfinished and locked.

These cases require the use of a specific construction heating system. Functional heating or surface-ready heating with the heat pump acc. To DIN EN 1264 is only permitted when complying with these conditions. Furthermore, it must be noted that the design of the heat pump concerning its standard operation may not yield the full extent of the required heat output. The following notes must be observed as well: The corresponding rules and regulations of the floor/screed manufacturer! Proper function is only ensured with a correctly installed system (hydraulics, electrical, settings)! Deviations may damage the floor/screed!

Ensure the following points are implemented and checked before the initial startup of the heat pump:

• The control box is installed and

completely connected.

• The heat pump is professionally

and completely installed (hydraulics and electrical).

• All external system components

required for operating the heat pump (circulation pumps, three-way valves, sensors, etc.) are completely and professionally connected.

• The hydraulic connections have

been established completely and professionally.

• All sensors are professionally

installed, shielded, and positioned in the correct locations as outlined by the respective system scheme.

• The heating system is pro-

fessionally installed and has been flushed, charged, vented, and checked for leaks as per rules and regulations.

• The electrical voltage meets the

requirements listed on the type plate of the heat pump.

• All fittings are in operational position.

The following persons must be present to carry out the initial startup process:

• The planer; he or she must indicate

the operational parameters.

• The installer; he or she is

responsible for the functionality and settings of the hydraulic system.

• The system maintainer (customer

or representative); he or she will be instructed in the operation and functions of the system.

If an initial startup is requested without all of these conditions having been met, ELCO rejects any responsibility for system malfunctions or other operational problems. In this case, the system is operated at the risk and responsibility of the owner.

Parameterization

The heat pump and the entire system is controlled with the integrated LOGON B WP61 controller. Please consult the system documentation for the correct parameter settings.

After the Initial Startup

After the initial startup is finished, the AEROTOP T heat pump does not equire any additional interventions or adjustments to the controller. Any desired heating temperature adjustments can be made in accordance with the enclosed user manual for the LOGON B WP61 controller.

Controller Function

Different temperature sensors and ¨ measuring elements in the heat pump, at the exterior air, in the system, in the storage tank, in the hot water tank, and possibly also in the living quarters are used by the controller. If and as needed, the controller passes a heat demand signal to the heat pump. The input of a heating curve is used to control and adjust heating temperatures. The heat pump as well as the system is controlled automatically. The system-relevant parameters are entered when commissioning the climate-based controller.

Heat Pump Upkeep

The AEROTOP T heat pump does not require any special upkeep. However, it is important to keep the system clean and in good working order. The specified leak checks must be carried out as well. From an energetic viewpoint, it is also recommended, especially in case of a new construction, to have the heating parameters checked and optimized by a service technician during the second winter after the initial startup since the initial humidity has now evaporated from the building and the required heating output is less than initially.

Primary focus should be on keeping air intake and outlet free of dust and other foreign particles or objects. The air intake and outlet openings must be kept free of obstructions (e.g. leaves, vehicles, debris).

Only trained and authorized service technicians are permitted to service AEROTOP T heat pumps.

The warranty becomes null and void if the system or heat pump is serviced by other persons or companies that are not authorized to do so.

Error Messages

AEROTOP T heat pumps function without problems as long as the different parameters do not deviate from the intended or specified values. If one or several of these parameters exceed the limit values, the controller depicts the corresponding error in plain text and stops the heat pump if required to protect the different components. The different error messages are described in the LOGON B WP61 user manual. The heat pump is released again with some errors (automatic acknowledgement) once the intended status has been reached again. It is also usually possible to release the heat pump manually.

In order to ensure reliable functionality of your system, we recommend purchasing a maintenance/ service contract.

Air Connections

Air intake and air outlet systems must be protected with grating and kept clean.

It is recommended that light wells are insulated with a sound damping, weather resistant material to prevent dampness problems inside the house The light wells must be drained. The air intake and outlet openings must be kept free of obstructions. Make sure they are installed accordingly. Parking lots or leaves accumulating in fall and possibly suctioned into the system are a problem.

Select the air outlet in such a way that the emerging blast of air is not directly pointed at people, animals, or plants.

The air suction and discharge must not be oriented as the windflow. The correct functioning could be compromised by the wind action.

Duct Length

The possible duct lengths are derived from the available pressure and the pressure loss indicated for the respective accessories.

If the air ducts are more than 3 meters long each side, an accurate design is required. In wind exposed places the uncontrolled airflow can be controlled by using shutters

Due to the radial fan, the available pressure is more than sufficient and can be adjusted for all models T07 to T16, as weel as all T..R, with LOGON B WP61 heat pump controller to meet the needs of the respective system. Please comply with the fan speed setting values (page 18).

Air Intake

The air intake (A) is at the rear of the AEROTOP T. It is possible to place the heat pump against the exterior wall (use wall opening kit WAI). If this instal lation type is not possible, use the air intake box and a flexible duct to connect to the heat pump. The duct can then be directed to the left, right, or the top. Flexible ducts are not possible with AEROTOP T 20 to 35 models and rigid ducts must be used. These are to be connected to the heat pump with a flexible sleeve. Noise dampers for air intake and air outlet are recommended for AEROTOP T20 to T35 heat pumps according to page 35

Air Outlet

If the heating or utility room has two exterior walls, a space-saving corner installation is ideal with the heat pump being placed into the left or right corner. This is possible since the air outlet (B) can be mounted on the left or right side (use wall opening kit).

If a corner installation is not possible (e.g. because the room has only one exterior wall or in case of an existing building), use the panel to connect a flexible duct. The alignment of the air outlet sleeve can be directed to the right (R), left, or top (T) as needed by simply replacing the panel

If air intake and air outlet are connected to the same building side (parallel installation), it must be prevented that emitted air is suctioned back into the system by the heat pump (no air short--circuit!). Flexible ducts are not possible with AEROTOP T 20 to 35 models and rigid ducts must be used. These are to be connected to the heat pump with a flexible sleeve.

Noise dampers for air intake and air outlet are recommended for Forever AEROTOP T20 to T35 heat pumps according to page 35.

Outdoor Installation

Special Conditions, Installation Location

Special Rules for Outdoor Installations

Please observe the general setup, installation, and connection instructions. Place the heat pump on a level and solid surface with the necessary bearing capacity. If not available, provide a cement base, acc. to the snow height, so that the feet of the outdoor unit cannot be covered with snow. The heat pump must be aligned with the adjustable feet.

Heater flow and return must be as short as possible and well insulated to prevent heat losses. The condensate drain must be insulated and protected from frost and have a siphon with a min. height of 100 mm routed into a closed drain. The drain line must not have any crosssection reductions and must be sufficiently suitable to ensure problem-free drainage.

The controller unit must be installed inside of the building (temperature range of +5°C to +40°C). The wall openings for heater flow and return as well as the electrical cables must be carried out according to the rules and regulations. Especially the flexible electrical cables as well as the low voltage (230 or 400V) and the extra-low voltage (sensor and controller cable) must be shielded from one another.

Selecting the Installation Site

Air intake and outlet must be kept clean, unobstructed, and free of snow, leaves, plants, machinery, etc. Comply with min. clearances as specified for air intake, outlet, misc. ducts, and maintenance (see previous page). Avoid an air short-circuit at all costs. Use both sides for the air outlet if strong winds, for example, may cause an air short-circuit. The air intake must be protected from aggressive or corrosive substances such as ammonia, chlorinated substances, etc.

The AEROTOP T heat pump is very quiet. However, since noise is perceived differently by different people, the heat pump should not be installed near windows, sleeping or living quarters (porch, edge of pool, etc.). The distance to neighboring houses should be sufficient as well. It is not advised to install the heat pump in recesses (possible echo or air short-circuit). Local rules and regulations apply.

Observe the checklist notes when selecting the installation site for the correct setup of an air-water heat pump.

Prepunched Opening for Outdoor Installation of an Air-Water Heat Pump

A prepunched opening (1) for the lines routed from the rear of the enclosure into the ground is provided in the unit bottom behind the electrical panel. We recommend routing the lines this way for the heat pump installed outdoors. This involves pulling the heating lines, condensate connection, and the electrical cables through the opening.

General information

In systems with buffer storage, the flow volume over the heater distributor must not be larger than that of the load circuit (heat pump – storage); otherwise, a back-flow effect may be caused by the buffer storage. This would have a negative effect on the efficiency of the system and on the good functionality of the heat pump.

Sensor B3 activates the water heating. Both charge pumps Q3 and Q9 are activated. The thermal mixing valve ensures that the charge is not released to the storage tank until the min. charge temperature has been reached. Charging continues until the set point at sensor B31 has been reached. Protection from Legionella pneumophila bacteria and auxiliary heating to a higher temperature levels is carried out via electrical heater element R6.

Note:

To ensure the Multiaqua service water heat pump is functioning properly, the min. flow of 500l/h must be available in the system in the winter as well as the summer. This means several circuits must be equipped without automatically closing valves. The selected rooms must be those to be cooled during the summer.

AEROTOP T Cascade with PWH Isolating Circuit

A6 Remote control (option) B1 Flow sensor B3 Service water sensor B4 Storage sensor top B9 Exterior sensor

Application / Description:

Several heat pumps, uncoupled, with buffer storage and mixed heating circuit. A heat pump is specifically assigned the task of heating potable water. Water heating with water heater with external exchanger (Magro charge). Optimal with floor heating or radiator heating with variable flow to optimize run times and satisfy higher service water demands.

B10 Bar flow temperature sensor B31 Service water sensor B41 Storage sensor bottom N1 Heat pump controller (built-in)

Function Description: Heating Cycle

The heat pump is activated via sensor B4 and exterior sensor B9 when requesting heat. The storage charge pump Q9 starts running simultaneously. If the currently running heat pump cannot satisfy the energy demand within a specific time, an additional heat pump/heat generator switches on (additional activation controlled by sensor B10 and assigned set point). Charging continues until the set point has been reached at lower sensor B41. The heating circuit mixing valve Y1 is controlled via the flow sensor B1.

Hot Water

Sensor B3 activates the water heating. Both charge pumps Q3 and Q33 are activated. The thermal mixing valve ensures that the charge is not released to the storage tank until the min. charge temperature has been reached.

Charging continues until the set point at sensor B31 has been reached. Protection from Legionella pneumophila bacteria and auxiliary heating to a higher temperature levels is carried out via electrical heater element R6.

Thanks to the PWH isolating circuit, a HP can be dimensioned and selected specifically for producing potable water. For example, a heat pump can be combined with different outputs. This makes it possible to heat potable water more efficiently and allows to run the system more efficiently as well since the heat pump is only specifically assigned to heat potable water in the summer. While in heating mode, the outputs of the two heat pumps are added to cover the required energy demand.

AEROTOP T R with Active Cooling

A6 Remote control (option) B1 Flow sensor B4 Storage sensor, top B9 Exterior sensor

Application / Description:

Reversible heat pump (AEROTOP T), uncoupled, with buffer storage and mixed heating circuit, in combination with a distribution system suitable for heating and cooling (e.g.fain coil).

Function Description: Heating Cycle

The heat pump is activated via sensor B4 and exterior sensor B9 when requesting heat. The storage charge pump Q9 starts running simultaneously. Valves K28 remain in position AB-B. Storage is charged. Charging continues until the set point has been reached at lower sensor B41. The heating circuit mixing valve Y1 is controlled via the flow sensor B1.

K6 Electrical heater element SW Y1 Mixing valve gear K28 Cooling demand

Cooling Cycle

The heat pump is activated via sensor B4 and exterior sensor B9 when requesting cooling. The four-way valve Y22 of the heat pump is also actuated, which results in a process reversal of the heat pump: The heat out side (condenser) becomes the heat absorption side (evaporator), i.e. the heating system is now cooled and the source is heated. Valves K28 are activated simultaneously (position AB-A) and the buffer storage is reversed or discharged. The storage charge pump Q9 starts running simultaneously. Storage is charged. Charging continues until the set point in the buffer has been reached. The cooling circuit mixing valve Y1 is controlled via the flow sensor B1.

Hot Water

Optionally, water heating can be carried out by the Multiaqua - service water heat pump.

Important:

- When used in applications with active cooling, a vapor-diffusion cold insulation is mandatory for all system components (lines, pumps, cocks, charging, storage)!

- In case of floor heaters, only a partial cooling is possible with flow temperatures above 18°C! A condensate monitoring system must be provided!

- Use only in combination with a distribution system suitable for heating and cooling (e.g. fan coil)

- Process reversal valves K28 are recommended with active cooling using a system temperature of 7/12°C and large buffer storage volumes. In case of partial cooling applications (system temperature > 18°C, floor heating) can be omitted.
