4-RELAY ACTUATOR ITEM F430/4
By means of internal relays, this device executes the commands received
from the control unit or the sensor. It is needed to control loads such as 3-
speed fan-coils, motorised valves, pumps and electric radiators.
It has four independent relays which can be used to command two distinct
loads with ON/OFF function and to command a single load with open/close
function. To manage open/close loads the actuator must be confi gured
with the logic interlock of the two relays (see “Confi guration” section) and
contacts C1/C2 respectively must be considered to open and close the fi rst
valve and contacts C3/C4 to open and close the second valve.
The contacts assume different functions when the actuator is used to control
fan-coils.
Contact C1 is an ON/OFF contact and commands the valve. Contacts C2, C3
and C4 commands the ventilation minimum, average and maximum speed
respectively. The temperature control function automatically selects the
ventilation speed depending on the difference between the temperature set
by the user and the room temperature.
LEGEND
1) Load forcing key: pressing this key activates the loads connected to the
actuator. To activate the load its sensor must be kept unconnected.
2) Light indicator: signals that the relay contact is closed.
3) BUS: connection for bus cable.
4) Configurator socket: housing for the configurators.
