Base module with KNX for temperature and humidity measurement
• Base module without sensor for plugging onto a front module
• 1 analog input to connect temperature sensors with NTC 10k sensing element to measure room, oor,
or ceiling temperature
• 2 multifunctional binary inputs to connect window contacts or buttons
• Power supply via KNX bus, bus load < 5 mA
• Temperature control as continuous control (PID algorithm) for pure heating operation, heating and
cooling operation, and adjustable positioning variable as continuous positioning signal 0…100%, or as
pulse-width modulated (PWM) switching signal On/Off,
• Ventilation control across 3 settable switching steps for relative humidity, and 3 switching signal
objects On/Off, or one positioning signal object 0…100% to control a ventilation actor
• Via setpoints for room temperature and relative humidity adjustable via KNX bus
• Adjustable commissioning and control parameters
• Integrated bus coupler with programming button and LED
