ELSNER 70982 Cala KNX T 101- black RAL9005 Ambient Temperature Controller

The Cala KNX T 101 room temperature controller, model 70982, is a temperature control device designed for integration into the KNX system. This controller measures the ambient temperature and displays the current value through digits illuminated in white.

Key Features

The Cala KNX T 101 has an elegant and functional design, with a case made of glass, plastic and metal, available in black RAL 9005.

Dimensions and Assembly

The dimensions of the device are 55mm x 55mm x 35mm, with a mounting depth of approximately 7mm. The total weight is about 50g.

Control Functionality

The controller uses a PI controller for heating (one or two stages) and cooling (one or two stages), depending on the temperature. The adjustment takes place according to separate reference values or a basic reference temperature.

The measured temperature can be a combination of the value measured by the internal sensor and external values, with proportions adjustable in percentage.

User Interface

The user interface includes two touch buttons (+/-) for adjusting the room temperature. The display shows the current value or the reference value.
