ENGLISH

Make sure that the doors and windows are shut thight.

Avoid opening doors and windows as much as possible to keep the cool air in the room.

Clean the air filter regularly.

Blockages in the air filter reduce the airflow and lower cooling and dehumidifying effects. Clean at least once every two weeks.

Ventilate the room occasionally.

Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.

Use high fan speed for effective and fast cooling.

The unit gives its rated cooling capacity when the fan speed is high.

VMH09SB-1, VMH18SB-1, VMH12SB-1, VMH24SB-1 specifications

The Heat Controller VMH series, featuring the VMH12SB-1, VMH09SB-1, VMH24SB-1, and VMH18SB-1 models, represents a significant advancement in heating and cooling technology. These models are crafted to cater to diverse climate control needs, making them ideal for both residential and commercial settings.

One of the standout features across the VMH series is the variable speed inverter technology. This innovative approach allows the systems to adjust their cooling and heating output based on the room’s current temperature, leading to more efficient energy consumption and consistent comfort levels. Instead of frequently cycling on and off, these units operate at varying speeds, ensuring they maintain the desired temperature with minimal energy use.

Users can expect a high SEER (Seasonal Energy Efficiency Ratio) rating, particularly with the VMH24SB-1 model, which boasts efficiencies that can significantly reduce electric bills. This is not only beneficial for pocketbooks but also for reducing the carbon footprint, as these units utilize eco-friendly refrigerants that comply with the latest environmental regulations.

The VMH series is also equipped with a user-friendly digital thermostat, providing precise temperature control. Some models even come with remote control capabilities, allowing users to adjust settings from the comfort of their couch or while out of the house. This smart feature offers the convenience of programming schedules and settings that suit individual lifestyles.

Regarding installation, the VMH models are designed to be unobtrusive, with sleek and modern designs that fit seamlessly into various decors. The units are compact and come with flexible installation options, making them suitable for smaller living spaces as well as larger areas.

Moreover, the series includes a robust filtration system that improves indoor air quality by trapping dust, allergens, and other contaminants. This focus on air purification is essential for creating a healthier living environment, particularly for individuals with respiratory conditions.

In summary, the Heat Controller VMH12SB-1, VMH09SB-1, VMH24SB-1, and VMH18SB-1 units provide a blend of efficiency, comfort, and convenience. With their advanced inverter technology, high energy efficiency ratings, and smart features, these systems are designed to meet the demands of modern living while contributing positively to the environment. Whether for heating or cooling, the VMH series stands as a reliable choice for achieving optimal indoor climate control.
