EELECTRON HA08A01KNX DIN HEATING ACTUATOR 8 IN / 8 OUT

The HA08A01KNX device is a EIB/KNX DIN rail actuators for electrothermal valves with 8 Triac outputs at 24… 230V AC; the devices include 8 inputs for dry (potential-free) contacts.

The outputs can be configured as:

• 8 channels for valve control in ON / OFF or PWM

• 4 channels for 3-points valve control

Inputs can be connected to buttons or switches (potential-free) and can be used for on / off commands, dimming, shutters or blinds / scenarios, sequences, step commands, etc. Inputs from 1 to 4 can be configured as outputs to activate single signaling 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 an integrated PI controller for controlling heating and cooling equipment, valves, 2 and 4 pipe fan coils, etc. Additional 4 thermostat modules are available in the device for a total of 8.

Moreover, 8 logic blocks are available to implement simple expressions with logical or threshold operator or complex expressions with algebraic and conditional operators; It’s possible to use predefined algorithms as proportional controls of temperature and humidity or dew point calculation.
