AWT series

The AWT series includes 3 models with an All-in-one indoor unit, which means that it includes an indoor unit for control unit and a 250 litre stainless steel sanitary water storage tank water. In addition, it includes most of the elements required for installation (diverter valve, expansion tank, safety valve, ....).

By using components from leading suppliers (see table) and smart control, great energy savings and quiet operation are made possible. All AW-R32-M series are rated A+++.

Simple and cost-effective installation

In a monobloc system the outdoor unit has a closed refrigerant circuit and a heat exchanger. The outdoor unit can be connected directly to the heating system, which means that no refrigeration technicians are needed during installation. The automatic and self-learning defrost function, combined with the nano-coated evaporator, reduces defrosting time to a minimum and increases the efficiency.

Control your heating system

AWT-R32-M can be controlled locally or remotely thru smartphone or computer. Make all the necessary settings for an efficient, trouble-free operation with the new user-friendly touch display. Even when you are not at home you have full control of your heating system thru your smartphone or computer.

Two heating curves

AWT-R32-M uses a heat curve to provide a constant indoor temperature, regardless of the outdoor temperature. When the outdoor temperature drops, the heat pump raises the temperature of the water to the heating system and vice versa when the outdoor temperature rises. Different heating systems require different temperatures, e.g. floor heating and radiators. AWT-R32-M have the possibility to set two heating curves if you have two different heating systems in your home. With two heating curves the possibilities to save even more energy is possible and, in some cases, costs on components that would otherwise have to be installed in the system.

Anti-Legionella Program

Anti-Legionella Program

If sanitary hot water is provided directly from the HWT (hot water tank), the water inside the tank must be periodically heated to temperatures over 60°C to eliminate the risk of bacterial growth inside the storage tank. ES controls this sanitization function according to the parameter settings automatically for a healthy life.

Auto Heat-Cool

Auto Heat-Cool

ES unit utilizes Automatic Heat/Cool Switch-over function to enable the user a truly unattended automatic operation of the system. User can choose to set this mode based on the ambient temperature, room temperature, or a signal input from other external devices.

DHW Storage

DHW Storage

Sanitary Hot Water should have the top priority in any heating system (if it is included). ES system offers an enhanced 2-step sanitary water production logic, that allows the users better satisfy the heating requirements, while sanitary hot water is also tenable. User can choose to run the system for high temperature sanitary hot water when the heating load is low and for medium temperature sanitary hot water when heating load is high.

Dual Water Temperature

Dual Water Temperature

Different heating systems require differing levels of water temperatures, such as the case with floor heating systems and radiator heating systems. ES system provides the users with the ability to set up two separate heat curve programs, for different water temperatures. A low temperature curve for floor heating and a high temperature curve for the radiators. When high temperature water is required, ES unit runs high-heat-demanding curve. When high temperature water is no longer needed or after it is reached, the unit automatically switches to low-heat-demanding curve operation with lower water set temperatures for a more economical and energy-saving operation.

Eco Touch

Eco Touch

With a 4.3" touch screen operation panel, EcoTouch can combine various heating equipment, to optimize the energy consumption of the entire system as a whole. Its sophisticated control logic smartly manages the system components and allows the integration with other common control systems to satisfy the complex demands of various applications, for highly efficient operation while minimizing the power consumption.

Economical Operation

Economical Operation

As the ambient temperature drops, the heating efficiency of heat pumps drops along. In some countries or regions, when ambient temperature drops to a certain level, usage of other heating sources, such as a gas boiler, may become more economical than the use of the heat pump. ES unit allows the user to stop running the heat pump and turn on other heating appliances, when the ambient temperature drops to a certain level.

Error-Shielding

Error-Shielding

Unit Operation with minor errors. When ES unit detects an error, the related error code will display on the operation panel. If the error is a minor one that won t adversely affect the system, the unit keeps on operating under a safe working instruction despite of the error, whereby the living space can still be kept reasonably comfortable. However if the error may result in an unsafe condition, the system will shut down and won t start until the error is removed.

Heating curve control

Heating curve control

With the ES Heating Curve Logic users can set up the system to meet their optimum comfort levels based on the changing heat demand, insulation levels, etc. ES system can adjust the outlet water temperatures based on the ambient temperature, by continually monitoring and adjusting it in opposite direction with the current ambient temperature levels to ensure the optimum comfort in the living spaces.

Low noise

Low noise

ES units use a special variable speed fan motor and fan blades with innovative blade design to reduce the sound level given up from the heat pump. The compressor is placed in an extra compartment that is insulated with sound absorbing materials. With these technologies we achieve low sound levels that makes the units almost not hearable, even running at maximum speeds. The units can also be set to work during the night in even lower sound levels via weekly timers.

Power Consumption Peak-Evading

Power Consumption Peak-Evading

In some countries or regions, power companies encourage people to use less power at peak time by adjusting their pricing for consumed power based on the certain times of the day, called the peak timing. ES system has the ability to receive the related signals from the power company and adjust its operation or even stop its operation upon receiving the signal. When this function is activated, user can set up the operation of water pump and the control signal to other heating appliances, like gas boiler or oil boiler. This function is an excellent tool for maximized energy savings.

R32 refrigerant

R32 refrigerant

R32 is a eco friendly refrigerant. The conventional refrigerants used for inverter heat pumps today has a global worming potential (GWP) more then three times higher than R32 refrigerant which is used for the new ES heat pump Line. The units have also less refrigerant volume for the same or even higher heating capacities. With this refrigerant we fulfil the EU norms that are not mandatory yet, but will become in the future. It also contributes to a high efficiency working of the heat pump.

Reduced Setpoint for Heating

Reduced Setpoint for Heating

In this mode ES system adjusts outlet water temperature or room temperature to save energy and lowers the operation noise by reducing the working speed of the compressor and fan motor for optimum sleeping comfort.

Room Temperature Compensation

Room Temperature Compensation

When the water temperature control function is utilized, users can still connect the optional room temperature sensor to allow the ES system to adjust the outlet water temperature automatically based on the difference between the desired room temperature and the actual room temperature measured.

Room Temperature Control

Room Temperature Control

In addition to water temperature control function, users can also choose to control the room temperatures. In this mode, ES unit will manage the outlet water temperature and work towards achieving and maintaining the set room temperature.

Software Update

Software Update

ES unit is equipped with a USB port for any future software updates and improvements.

Unit Working Status

Unit Working Status

Installer and the user can view the real-time operation status of the unit, like working voltage/current, water flow, unit capacity, COP, temperatures readings, system high and low pressures, etc.

Vacation Mode

Vacation Mode

Built-in Vacation Mode allows the users to set the system to operate under minimized vacation settings between the programmed starting and ending time of their vacation periods. In this mode, ES system works to maintain the minimal required temperatures to save the maximum amount of energy. System will switch back to normal mode at the ending time of vacation mode properly, so that the occupants will be welcome with proper heating temperature and sanitary hot water, upon returning from their vacations.
