Review of split system HEC 09HTC03 R2: contender for the crown in the nomination "cheap and cheerful"

Comparison of characteristics of popular models

To select the optimal model of the Hec split system, it is recommended first of all to pay attention to the technical characteristics. The design of the indoor units is standard and can fit well into the interior of an apartment, office or workroom, as can be seen in the photo in the catalog. Considering that the manufacturing country is China, external inspection during the purchase and control of work during the warranty period must be approached carefully.

Considering that the manufacturing country is China, external inspection during the purchase and control of work during the warranty period must be approached carefully.

To compare models, it is recommended to study the following parameters:

• cooling, heating power;
• modes - autostart, timer;
• energy class;
• noise level during operation;
• dimensions of the indoor unit;
• requirements for minimum and maximum outdoor temperatures;
• price.

To simplify the task, you can familiarize yourself with the current parameters, as well as the price indicated in the table.

All systems use R410A refrigerant. It is safe for human health, in case of leakage it will not affect the situation in the room. But for the correct operation of the split system, it is necessary to maintain an optimal fluid level.

The nuances of using a split system

To ensure trouble-free operation of the unit, the manufacturer recommends an annual maintenance of the system and regular cleaning of the air filter. The first work should be entrusted to the specialists of the service center, and the user can handle the second task on their own.

Preventive maintenance consists of the following:

• washing of heat exchangers, cleaning of drainage trays;
• broach of connection contacts;
• checking the operating parameters of the refrigeration circuit, the condition of the terminals, printed circuit boards and connectors.

For cleaning air filter must be removed front panel of the indoor unit by lifting it up.

Next, you need to take the grill by the middle part, pull it up until a characteristic click - it should come out of the latches

The filter can be washed with water or vacuumed. It is installed back after complete drying and the cover of the block is closed. For more information on how to carry out preventive maintenance of the split, read on.

HEC Air Conditioner Error Codes and Malfunctions

During the operation of the split system, malfunctions may occur.They should be divided into two categories - malfunctions and global breakdown. In the latter case, you need to call a specialist to solve the problem. In the instructions, the manufacturer described some types of malfunctions and methods for solving them, but the error codes in the instructions for R2 Heck are not indicated, because. there is no self-diagnosis system.

In the event of a malfunction, do the following.

1. Reread the instructions.
2. Verify that the problem persists after restarting.
3. Proceed according to the manufacturer's recommendations.
4. Do not disassemble the unit yourself, except for cleaning the air filter.

Overview of reviews

If we talk about reviews of the split systems of the HEC line, then for the most part they are positive. Users note the excellent technical characteristics of all HEC models, high power and competent implementation of the functions of heating and cooling rooms. The high efficiency of the R410 refrigerant is also noted, which is used in these split systems.

There are, of course, negative reviews, but their number is relatively small and is within the margin of error when users are faced with a marriage that each manufacturer has.

An overview of the Haier Home Inverter series air conditioner, see the following video.

Terms of use

In general, they do not differ from the requirements that apply to similar split systems from other manufacturers. It should be said a little more about the modes of their work.

• Cooling. This mode lowers the temperature of the air masses in the room. The indoor unit has a special sensor that monitors temperature changes and sends a signal to the compressor unit. You can also change the fan speed within this function.
• Heating. This feature will be interesting, since the split system heat pump consumes significantly less electricity compared to a conventional heater.
• Ventilation. This mode drives air through the split indoor unit and filters it. This does not provoke changes in the temperature regime in the room - it simply recirculates without the influx and removal of air masses.
• Dehumidification. Excess moisture in the room is removed.

Many will be interested in the Auto mode. If it is active, then the split system automatically turns on either cooling or heating. That is, the air conditioner independently maintains the specified settings.

On the control panel in some models you can find a special key called Health. It activates the "Healthy climate" option. Its essence is the removal of various unpleasant odors and enhanced purification of air masses. But, as mentioned, this option is not present in every model.

The restart function allows you to resume the operation of the device at the previously saved settings. In the event of an emergency power outage, the device remembers the necessary parameters. After the power supply is restored to the device, it will tune in to the data that was before the failure.

The light indicator allows you to determine the presence of a breakdown during self-diagnosis and will let the user know about it.

You should also talk a little about the functions of the various keys that are present on the device's remote control. Depending on the configuration of the model, their number may vary. We will look at the most common:

• Cool - cooling;
• Heat - heating;
• Dry - dehumidification;
• Temp - setting the required temperature level;
• Swing - switching the split system to auto mode;
• Timer - setting the timer to turn on or off;
• Health - setting the "Healthy climate" function;
• Lock - blocking the remote control;
• Reset - reset settings to factory values;
• Fan - change the speed of rotation of the cooler;
• Light – panel illumination of indoor module indication.

Advantages and disadvantages of the device

In technical terms, the unit is very well “savvy”. It provides the main systems for protecting equipment from failures, significant functions and options are implemented.

Among the main advantages of the HEC 09HTC03 split are: compactness of the modules, quiet operation, despite the absence of an inverter compressor, a complete set of accessories for installation, ease of control

The popularity of the model, first of all, is due to its affordable price and advanced functionality. Most users are happy with the purchase.

Among the minuses, some consumers distinguish:

• the duration of cooling, heating to the desired temperature;
• with poor-quality installation, the external module vibrates;
• during the change of modes, a slight crackling is heard;
• not economical consumption of electricity;
• no backlight on remote.

In general, the device is worth its money. In most cases, the inefficient operation of the split is associated with unscrupulous installation - poor rolling led to freon leakage. In order not to encounter such a problem, we recommend that you study the installation instructions for the split system.

The lineup

As already mentioned, the range of this series is not diverse. The shape and color of such air conditioners can be called standard because of the white indoor unit, which has somewhat rounded edges.The outdoor unit does not differ in any particularly original design, but thanks to a competent layout, it is as reliable as possible.

The choice of model should be made based on the scope: for an office, apartment or some kind of technical or office space.

To date, models with index 03 in their names are the newest. There are several sub-series, each of which has certain features.

HDR R. This is the most affordable category of split systems. To optimize the control of work, there are 6 modes here, depending on the external parameters in the room: humidity, air temperature, and so on. There is no automation here, so all parameters are set manually.

If we talk about specific models, we should start with HEC-07HTD03/R2. This split system has 4 operating modes: cooling, ventilation, heating and dehumidification. This model is best used in rooms with an area of ​​​​up to 20 square meters. meters. Power consumption is 730W in cooling mode and 635W in heating mode. If we talk about the total power, then it is 2050 watts in both modes. As for the noise during operation, for the indoor unit its level will average 32 dB, and for the external one - 52 dB. The refrigerant used here is R410A, which is considered to be very efficient.

The model also has the functions of automatic selection of the operating mode, timer, automatic restart, night mode.

The next model to be mentioned is HEC-12HNA03/R2. This split system also has 4 operating modes: ventilation, heating, dehumidification, cooling. The recommended floor area for its work is 35 square meters.Power in cooling mode is 3500 W, and when heated - 3800 W. If we talk about the noise level, then for the internal block it is 30 dB, and for the external - about 50 dB. Here, as in the previous model, refrigerant type R410A is used.

As for the functionality of the model, there is an automatic selection of the operating mode, automatic restart, timer and night mode. In addition, there is a remote control. The indoor unit is also equipped with a special display. Separately, it should be said that this is a 2019 model and is not yet available everywhere.

Another model that needs attention is the HEC-09HTC03/R2-K. This split system can operate in both heating and cooling modes. The area served by it is 20 square meters. It can generate a maximum airflow of 8 cubic meters per minute. The refrigerant type R410A is also used here. Separately, it should be said that there is a remote control here, and a special remote control is included. There are also functions of night mode and automatic switching on and off of the air conditioner. Cooled air can be supplied in two modes: turbo and sleep. The features of this model are the ability to adjust the strength and direction of the air flow.

If we talk about the noise level of this model, then for the indoor unit it is 35 dB, and for the external one - 52 dB. Power consumption in cooling mode here will be 885 watts, and heating - 747 watts.

Peculiarities

If we talk about the features of the model range of HEC air conditioners, then it does not differ in any serious variety. Frankly, this is an improved budget split series from Haier.HEC devices, which have the designation R2 in their names, refer to split systems with simple compressor units.

The wall part has a traditional look. The set of such HES systems usually includes:

• outdoor module, which is white;
• indoor unit;
• remote control with a pair of batteries;
• installation accessories;
• instruction manual for the device;
• warranty card.

If we talk about the performance of the indoor unit, then, as a rule, it is as concise as possible. Thanks to this, it suits various interior styles. Air inlets are located on the top of the unit, outlets are on the bottom.

Vertical and horizontal louvers are designed to conveniently control the direction of the air flow. There is an air filter under the front panel. It is removable and provides partial cleaning of the air flow. It needs to be cleaned regularly to remove dust and dirt.

The location of the information display is quite convenient. It is usually located at the bottom of the block on the right. Here you can also find a number of indicator lights:

• power supply - lights up green when the device is active;
• "timer" mode - if it is active, it lights up orange;
• Work - it glows when the device is working.

An infrared receiver is located next to the screen - when it works, an audible signal is generated. And a little higher on the right is the emergency shutdown key.

The outer unit is made of metal and is quite compact. Its weight is just under 25 kilograms. An outlet type grill can be found in the front, and an air inlet is located on the side.

On the right side of such models, the interconnection wire and the refrigeration circuit pipe are connected.

Comparison with similar models

In order to assess the competitive advantages or disadvantages of the unit under consideration, it is advisable to compare its parameters with similar values ​​of air conditioners of the same price category. For comparison, let's take three splits from other manufacturers with similar power and cost.

Competitor #1 - Scoole SC AC SP9 09

budgetary Chinese brand offer with good set of functions. The air conditioner is designed to serve rooms within 25 sq. m, cooling capacity, like that of the HEC split - 9000 BTU.

Specifications:

• operating modes - heating, cooling, drying and ventilation;
• performance for cooling and heating - 2.7 kW and 2.75 kW, respectively;
• power consumption - 756-840 W;
• noise pressure of the indoor module - 24-33 dB;
• the minimum outdoor temperature for heating is from -15°С.

In terms of functionality, the model is not inferior to the unit from HEC. There is an automatic, night mode, the option to remember settings, a timer, system self-diagnosis, fan speed control. Air conditioners are similar in size.

Advantages of Scoole: energy efficiency, quiet operation of the split, fan operation at 4 different speeds. Reviews about the air conditioner are mostly positive: good quality plastic, the unit works efficiently, the external unit is treated with an anti-corrosion coating.

Competitor #2 - Roda RS-A09F/RU-A09F

Another representative of the "nine" series from a Chinese company. The price of the air conditioner is slightly higher than the cost of HEC 09HTC03.The model is very popular among buyers - this is evidenced by many user reviews.

Specifications:

• basic modes: cooling, air heating, dehumidification, ventilation;
• split performance - 2.65 kW and 2.75 kW for cooling and heating, respectively;
• power consumption - 825 W;
• noise from the indoor unit - 33 dB;
• space heating at outdoor temperature not lower than -5°C.

Roda products are in good standing with consumers. Air conditioners are assembled at the AUX plant, where more expensive brands Dax, Midea, Pioneer are also produced. Roda units have a rotary compressor from Toshiba.

Numerous reviews allow us to conclude about the main advantages of the split: the rapid achievement of the desired temperature, the quiet operation of the internal module, affordable pricing, good build quality. Users note simple operation, full functionality, convenience of temperature indication on the front panel. Some use the air conditioner even to cool rooms with an area of ​​​​about 30 square meters. m.

Compared to the HEC split, this model loses in two ways. Firstly, room heating is possible at a temperature of -5 ° C and above, and secondly, the distance between the blocks is reduced to 10 m. The disadvantages are very conditional, but these features should be taken into account when choosing a household unit.

Competitor #3 - Hyundai H-AR2-07H-UI016

Specifications:

• 4 main modes: cooling, room heating, dehumidification, blowing;
• unit performance - 2.39 kW and 2.3 kW for cooling and heating;
• electricity consumption - 800-820 W;
• noise from the internal module - 31 dB;
• the minimum temperature for room heating is -5°C.

The device has a built-in anion generator, there is a night and automatic mode. Of the features of the split, the presence of the “warm start” option can be distinguished. The technology does not allow cold air to enter - the fan turns on only after the air flow has been preheated to the temperature set by the user.

The main plus of the Hyundai air conditioner is a good ratio of price and technical parameters. Cons identified by users: noisy external unit, compressor relay makes clicks when switching modes, plastic looks rather flimsy.
