SK07-TTHC-4B (ohne phys. Sensoren)

Description

• Air temperature (external connection, PT1000)
• Air temperature and humidity (external connection, SHT71)
• Calculated values absolute humidity, dew point temperature and energy content (enthalpy)
• Primary temperature input also weighted with additional mixing temperature
• Control functions for heating and cooling applications (can be combined)
• Setpoint temperatures for Comfort, Standby, Economy and Protection, selectable via KNX HVAC objects
• Setpoint change via objects
• Storage of minimum and maximum temperature
• Heat and frost alarm
• Limits for temperature, humidity
• Fan control via humidity limits and external inputs
• Detecting of dew point temperature with alarm / regulation at risk of condensation
• Adaptation for setpoint and limits temperatures
• Controller output 0..100% or programmable PWM for thermal actuators
• Valve rinse function
• Second temperature controller as auxiliary controller

Four binary inputs / outputs (floating)

• Light control as switch / button with short, long, double and both function
• Dimmer
• Blind and shutter control
• Programmable Encoder
• Temperature adjustment
• The binary inputs can be configured as outputs (LED / Beeper)

Four logic blocks for the logical link between internal and external signals

• 10 associated logic inputs / outputs
• Heat- and cooling-request as additionally available signals
• Functions "AND, OR, NOT, XOR" for binary logic
• Functions "+ - *" for 8-bit values
• Function "=" for conditional forwarding of events

Applications

• Detection and control of room temperature and humidity
• Decentralised control for steady KNX-valves or thermal actuators
• Decentralised ventilation control depending on humidity and air quality
• Detecting of component temperature and temperature control to prevent condensation and structural damage
• Evaluation of external switches and push buttons for switching functions
