ARCUS-EDS 30516361 SK30-TC-RSTF White

ARCUS-EDS 30513261 Product Description

The KNX SK20-TC-VOC-2B sensor from Arcus-EDS GmbH is a specialized device for measuring and controlling indoor temperature and air quality. This sensor is designed to be integrated into KNX-based climate control systems.

Key Features

• Internal temperature measurement with an HTU21 sensor, with a resolution of 0.02°C and an accuracy of ± 0.4°C (between 5°C and 60°C) and ± 0.8°C outside this range.
• Measurement of the level of VOC (Volatile Organic Compounds) with a range of 400.. 10000 ppm of CO2 equivalents.
• Combined control for heating and cooling applications, with setpoint temperatures selectable for Comfort, Standby, Economy and Protection.
• Change setpoints through KNX objects.
• Storage of minimum and maximum temperatures.
• Alarm for overheating and freezing.
• Temperature limits.
• Fan control via external inputs.
• Adaptation for setpoint and maximum temperatures.
• 0... 100% controller output or programmable PWM for thermal actuators.
• Valve flushing function.
• Second temperature controller as an auxiliary controller.
• Two binary contacts.
• Four logical blocks for the logical connection between internal and external signals.
• 10 associated logical inputs/outputs.
• Request for heating and cooling as additional signals available.
• “AND, OR, NOT, XOR” logical functions for binary values and “+ - *” functions for 8-bit values.
• “=” function for conditional forwarding of events.
