The discreet design of the T9000 thermostats blends harmoniously into any interior. Its square shape with rounded edges and its clearly structured display lend the device an unobtrusive appearance. In the development of the series, great importance was placed on compatibility. The thermostats are equally suitable for heat pumps and ventilation units. They are designed for use with electric cabinets in Europe and Asia and can be easily retrofitted thanks to the use of simple and standardised components.
