To reach that even temperature and the desired climate, humidity plays a big part. Moisture in the air has a negative effect on one’s health, so it is important to know that our heating airconditioning dehumidifies continuously. Rot, rust, mold and unpleasant odors do not stand a chance to develop and lead to dust mites and allergens. The heating airconditioning also cleans the air with the built-in carbon and dust filter. The heating in the heating airconditioner takes place by using ceramic heating elements. It is easy to use the heating airconditioning, the only thing you have to do is enter the day and night temperatures and the climate control system does the rest! It really could not be more simple. The heating airconditioning has a light sensor for automatic switching between the day and night program and also, dehumidifying during day, night or continuously, is possible. The heating airconditioning comes with a clear comprehensive remote control and you can easily choose the pre-heat function, the slow cool-down function and alarm log function. You can also choose for a dual room function option, with which you can heat or cool two spaces with just one OptiClimate. The fan of the PRO3 can be placed in two different positions (not the Inverter).
