Technical data

Siemens Building Technologies SpA
Respect current regulations for wiring. The devices should be directly connected to mains
(that is with no switches, etc.) and be permanently powered up.
The positive logic operation of internal relay means an always energized contact (C-NC
open) in no alarm and/or fault condition.
EV control output is solid state type and is sized for an INTELLIGAS
valve with 13W maximum absorbed power. It is not to be used to drive solenoid
valves with higher power consumption.
Indicate control unit number and sensor corresponding to the gas type to be detected
