ELSNER 70810 Cala Touch KNX TH 3.x- RAL 9010 pure white Environment Controller with Temperature/Humidity Sensor

The ELSNER 70810 KNX room controller, known as Cala Touch KNX TH, is a versatile and highly functional device for the KNX bus system. This device combines a color touch screen display with environmental control, lighting and mechanical device management capabilities.

Display and Interface

The Cala Touch KNX TH features a color touch screen display with a visible diagonal of 2.3 inches (59 mm) and a resolution of 320 × 240 pixels. The structure of the device includes an authentic glass and plastic frame, available in two colors: pure white RAL 9010 and jet black RAL 9005.

Control Functionality

• Display of current measured values.
• Bus data display (4 universal spaces).
• Temperature control (including changing the mode and indicating if heating or cooling is active); it can also be used as an extension unit to operate another controller.
• Operation of 3 drives (shading, windows) with buttons, sliders and position display (including the position of the blades).
• Turn on or adjust the intensity of the light (with percentage display).
• RGB light control.
• Setting the color temperature of the light.
• HCL control (adaptation of the color temperature of the light over adjustable periods of time).
• Scenes (4 scenes with recall, memory and status indication).
• Weekly timer switch with 8 periods.
• 2 pages of information (each displays 2 text objects).

Sensors and Environmental Conditions

• The device includes an integrated temperature and humidity sensor.
• Temperature measurement range: -20°C to +70°C.
• Humidity measurement range: 0% RH to 100% RH.
• Ambient operating temperature: 0°C to +45°C.
• Ambient humidity (non-condensing): 5% to 95% RH.

Installation and Protection

• Flush mounting (wall mounting in Ø 60 mm junction box, 42 mm deep).
• Degree of protection: IP20.
• Dimensions: approximately 55 × 55 × 35 mm (W × H × D), mounting depth approximately 7 mm.
• Total weight: about 90 grams (including power cable and base plate).

Additional Logic and Functionality

• 4 inputs for binary contacts or T-NTC temperature sensor.
• 8 AND logic gates and 8 OR logic gates, each with 4 inputs.
• 8 multifunction modules (calculators) to modify input data through calculations, condition queries or data point type conversion.
• 4 variable comparators manipulated to output minimum, maximum or average values. 5 inputs each for values received through communication objects.
