Overview of HEC air conditioners, error codes and instructions for the control panel

Household climate systems of the Hec trademark are produced by the well-known Chinese manufacturer Haier. The first models appeared on the Russian market in 2011 and gained popularity due to the simplicity and reliability of the design, and at a democratic price. The only difficulty in choosing is a small assortment of Hec split systems. But with the right analysis of possible options, you can always find the best one.

Assortment overview

The range of split systems of this brand does not differ in variety. In fact, Hec air conditioners are a slightly modernized budget Haier series. The shape and color are standard - a white inner block with slightly rounded edges. The outer one does not differ in the original design, but thanks to the competent layout it is reliable.

The choice must be made according to the field of application - for an apartment, office or other office space. The 203 series is the last in the line of models and is characterized by the following features, depending on the type:

• HDR R The most affordable split system Hec. To optimize the control of work, 6 modes have been introduced, depending on the external parameters in the room - air temperature, humidity. They are set manually, there is no automation.
• HNB, HNC and HNA R2. They are characterized by a large selection in terms of power, but structurally do not differ in any way from the above-described model. The advantage is that a more efficient air filter is integrated.
• DB series. These are inverter split systems designed only for high-power models. The positive aspects are energy savings and minimal refrigerant evaporation rates.

For unification, the manufacturer uses a single control panel. Some of the control buttons may be grayed out depending on the model. This point must be checked with the seller before buying.

The horizontal louver adjustment (left / right) can only be done manually. Therefore, the indoor unit should not be placed too high on the wall of the room.

Comparison of characteristics of popular models

To select the optimal model of the Hec split system, it is recommended to first of all 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 work room, as can be seen in the photo in the catalog. Considering that the country of origin is China - you need to carefully approach the external inspection during the purchase and control of the work during the warranty period.

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

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

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 the event of a leak, it will not affect the environment in the room. But for the correct operation of the split system, it is necessary to maintain an optimal fluid level.

When servicing the climate system, only the refrigerant recommended by the manufacturer must be refilled. If another brand is selected, the lines are pre-cleaned, purging is performed.

HEC air conditioner error codes and malfunctions
