AC/DC 24 V, modulating (VAV)
The VAV controller operates with setpoint adjusted through analog input signal (terminal 3) and feedback signal
(terminal 5).

Additional functions can be activated by connecting the override inputs z1 and z2.
The priority of these functions is higher than the VAV modulating operation with analog input.
Override control z1
Contact 11-9 = Motor STOP
Contact 11-10 = Damper OPEN
Override control z2
Contact 12-13 = Damper CLOSED
Contact 12-14 = V

11 and 12 without contact = no priority override through z1 or z2
