ELSNER 70645 KNX TH-UP gl CH- jet black RAL 9005 KNX temperature/humidity sensor

MT Code: ELS_70645
Manufacturer Code: 70645
Brand: ELSNER

The KNX TH-UP gl sensor, ELSNER code 70645, is a specialized device for measuring temperature and humidity in the environment, designed to be integrated into KNX home automation systems.

Key Features

This sensor measures absolute and relative temperature and humidity, also calculating the dew point. It is able to receive values measured externally via bus and to process them with its own data to obtain overall values, such as the average temperature in a room.

Measurements and Installation

The sensor has a glass and plastic housing, available in two colors: pure white (similar to RAL 9010) and black (similar to RAL 9005). The dimensions of the housing are approximately 60 mm x 60 mm, with a mounting depth of approximately 8 mm. The total weight is about 50 grams.

Environmental Conditions

Ambient operating temperature: 0°C... +50°C
Storage temperature: -10°C... +60°C
Maximum relative humidity (RH): 95%, avoiding condensation

Technical Functionality

The sensor operates with a nominal voltage of 30 V SELV and a maximum consumption of 10 mA. It is equipped with KNX +/- connection terminals and supports up to 254 group addresses and 254 assignments. It has 158 communication objects.

Measurements and Controls

Temperature measurement range: 0°C... +50°C
Humidity measurement range: 0% RH... 95% RH
Temperature control with PI regulator (one or two steps) for heating and cooling
Humidity-based ventilation control: dehumidification/humidification (one or two steps)
Adjustable threshold values for each parameter or via communication objects: 3 × temperature, 2 × humidity

Connections and Logic

The output signals can be connected using AND and OR logic. In addition, the sensor includes an integrated drive variable comparator that can compare and output values received via communication objects.
