Description

UK (British Standard)

Base module with KNX for temperature and humidity measurement

  • The room sensor for flush mounting consists of a base - and front modüle
  • Temperature control as continuous control (PID algorithm) for pure heating operation‚ heating and cooling operation‚ and adjustable control value as continuous control value 0…100%‚ or as pulsewidth modulated (PWM) switching signal On/Off
  • Ventilation control across 3 settable switching points for relative humidity‚ and 3 switching signal objects On/Off‚ or one control value object 0…100% to control a ventilation actuator
  • Setpoints for room temperature and relative humidity adjustable via KNX bus
  • 1 analog input to connect temperature sensors with NTC 10k sensing element to measure room‚ floor‚ or ceiling temperature
  • 2 multi-functional binary inputs to control window contacts or switches for blinds and/or lighting control
  • Settable commissioning and control parameters
  • Power supply via KNX-bus‚ bus load < 5 Ma
  • Integrated bus coupler with programming button and LED
