ARCUS-EDS 30541352 SK30-TTHC-R Dark grey

The ARCUS-EDS 30541352 product, called SK30-TTHC-R, is a temperature and humidity controller designed for air conditioning and heating applications within the KNX system.

Key Features

This device integrates temperature and humidity sensors inside its housing and offers a connection for an external PT1000 sensor.

Temperature and Humidity Control

The SK30-TTHC-R allows you to adjust the temperature for comfort, standby, economy and protection. The setpoint can be changed using a rotary controller or KNX objects.

The device also manages alarms for overheating and freezing, and includes temperature and humidity limits.

Control functions

• Decentralized ventilation control based on humidity.
• Condensation temperature detection and adjustment to prevent condensation.
• Temperature component control and temperature regulation to prevent structural damage.
• Valve rinse function for thermal actuators.
• Second temperature controller as an auxiliary controller.

Interface and I/O

The device includes two binary (floating) inputs and outputs that can be configured as outputs (LED/Beeper).

The rotary controller allows you to change the operating state (comfort/standby) and to increase/decrease the temperature setpoint in several steps.

Logic and Signals

Four logical blocks for the logical connection between internal and external signals.

• 10 associated logical inputs and outputs.
• “AND, OR, NOT, XOR” logical functions for binary values.
• “+ - *” functions for 8-bit values.
• “=” function for conditional forwarding of events.

Technical Data

Temperature range: -20°C to +80°C, with accuracy ± 0.3°C and resolution ± 0.01°C.

Humidity range: 0% to 95% R.h, with accuracy ± 3% R.h (20-80%) at +20°C, otherwise ± 5% R.h.

KNX Bus supply voltage: 21-32VDC, with an approximate power consumption of 240mW (at 24VDC).

Operating temperature: -20°C to +80°C, humidity: -20°C to +85°C for storage and -20°C to +80°C for operation.
