Datasheet

SK10-THC-KFF – KNX duct sensor for temperature/humidity

Item no: 30531057

The SK10-THC-KFF by Arcus-EDS is a KNX sensor for temperature and relative humidity, designed for installation in ventilation ducts with an inner diameter from Ø150 mm. It features integrated measurement and control functions and is suitable for HVAC applications in building automation. Its robust housing and IP54/65 rating make it resistant to demanding conditions.

Applications

• Measurement and control of temperature and humidity in ducts
• Indoor climate control in HVAC systems
• Dew point monitoring to prevent condensation
• Fan and humidity control via KNX

Main features

• Air temperature measurement (sensor on housing)
• Relative humidity (sensor on housing)
• Calculated values: absolute humidity, dew point, enthalpy
• Control functions for heating and cooling (combined if needed)
• Selectable setpoints: Comfort, Standby, Economy, Protection
• Setpoint adjustment via KNX objects
• Recording of minimum and maximum temperature
• Heat and frost alarms
• Threshold monitoring for temperature and humidity
• Fan control via humidity thresholds or external inputs
• Dew point detection with alarm and regulation
• Adjustable setpoints and limit functions
• Controller output: 0–100% or programmable PWM
• Valve flushing function
• Secondary temperature controller (auxiliary)
• 4 logic blocks for internal/external KNX signals
