ELSNER 70973 70973 KNX VOC/TH-UP Touch Mixed Gas/Temperature/Humidity Ambient Controller, Black

The KNX VOC/TH-UP Touch sensor, model 70973, is a versatile and sophisticated environment controller, designed to measure and adjust various environmental parameters. This device measures the volatile organic compounds (VOCs) present in the room air, the temperature and the humidity, and calculates the dew point.

Key Features

• Measurement of volatile organic compounds (VOCs) in the range from 400 to 2000 ppm with a resolution of 1 ppm.
• Temperature measurement in the range from 0 to +50°C with a resolution of 0.1°C and an accuracy of ± 0.5°C.
• Relative humidity measurement in the range from 0% to 95% RH with a resolution of 0.1% and an accuracy of ± 7.5% RH at 0-10% RH, ± 4.5% RH at 10-90% RH and ± 7.5% RH at 90-95% RH.

Control Features

The device includes a PI controller for ventilation based on humidity and VOC concentration, allowing dehumidification/humidification (one or two stages). The threshold values can be adjusted for each parameter or through communication objects.

• 4 AND logic gates and 4 OR logic gates, each with 4 inputs, which can use switching incidents or logic inputs as communication objects.
• 2 comparators of drive variables for the output of minimum, maximum or average values, each with 5 inputs for values received through communication objects.
• Two pressure buttons that can be used to change the ambient temperature (target value), to switch between operating modes or as freely programmable bus buttons.

Integration and Configuration

The device is configured using the KNX ETS 5 software. It operates on a KNX bus supply voltage and has a maximum current consumption of 20 mA.

• Support for up to 254 group addresses and 254 assignments.
• 224 communication objects available.
• Integrated display that shows the measured values and the data received from the bus, such as date and time.

Installation and Design

The KNX VOC/TH-UP Touch sensor is wall-mounted and available in black (RAL 9005). It requires a Ø 60 mm housing, 42 mm deep and a frame suitable for the switching program used in the building.
