The HA04A01KNX device is a DIN rail EIB/KNX actuator for the control of thermoelectric valves with 4 Triac outputs at 24… 230V AC; The device also includes 4 inputs for dry contacts (potential-free).
The outputs can be configured as:
• 4 channels for ON/OFF or PWM
valve control• 2 channels for 3-way valve control
The inputs can be connected to potential-free buttons or switches and can be used for on/off commands, dimming, shutters or blinds/scenarios, sequences, stepper commands, etc. Inputs 1 to 4 can be configured as outputs to activate individual signalling LEDs (see eelectron LEDs code LD00A01ACC / LD00A11ACC) or can be configured as analogue inputs for the connection of NTC temperature probes (see eelectron probes code TS00A01ACC / TS00B01ACC) with which to send 4 temperature measurements on the bus or to manage 4 complete thermostat modules.
Each thermostat module manages 2 stages with integrated PI controller for driving heating and cooling equipment, valves, 2 and 4-pipe fan coils, etc. An additional 4 thermostat modules are available in the device for a total of 8.
There are also 7 logical blocks with which to create simple expressions with logical or threshold operators or complex expressions with algebraic operators, conditional expressions with algebraic operators, and finally use predefined algorithms such as proportional temperature and humidity controls or dew point calculation.
