ELSNER 71162 KNX eTR 205 Light, black RAL 9005

The ELSNER 71162 device, known as KNX eTR 205 Light, is a room temperature controller that integrates various functions for climate control and lighting.

Key Features

This device is designed to be mounted on the wall and has a plastic and glass structure, available in two colors: RAL 9003 (white) and RAL 9005 (black).

Dimensions and Assembly

• Dimensions of the enclosure: approximately 81.5 x 81.5 mm (width x height)
• Mounting depth: about 12 mm
• Total weight: about 70 g
• Direct wall mounting or with a Ø 60 mm wall socket or with a Ø 68 mm hole socket

Environmental Conditions

• Operating temperature: 0°C... +55°C
• Storage temperature: -30°C... +85°C
• Relative air humidity: 5%... 95% RH, avoid condensation

Temperature Control Functionality

The device includes an integrated temperature sensor and can receive external temperature values through the KNX bus, allowing a mixed value to be calculated between internal and external measurement, with a proportion that can be set as a percentage.

• Temperature control with two areas (warmer, colder)
• PI-controller for heating (one or two levels) and cooling (one or two levels) based on temperature, with separate setpoints or basic setpoints
• Output of minimum and maximum values

Functionality of LEDs and Buttons

The LEDs can be configured in different ways:

• All LEDs off
• All LEDs as ambient lighting
• Individual control of each LED

The buttons can be configured for different functions:

• switchgear
• Selector
• 8- or 16-bit encoder
• Recall scenarios

Power and Connectivity

The device operates on the KNX bus voltage and has a maximum consumption of 25 mA.

• Connectivity via KNX +/- bus terminals

Protection and Security

The device has an IP 10 degree of protection and complies with safety regulations relating to overvoltage category III and degree of contamination 2.
