Does Emmeti’s Modulo Compact and Modulo Plus Motorised ball valves have an end switch/ auxiliary switch/ proving switch ?

Yes, each actuator has an auxiliary switch (this is the same as an end switch or proving switch).  This is designed to switch on when a 2-way (zone) opens (or switches flow direction in the case of a three-way valve) and allows a boiler, for example, to be switched on when the valve opens and off again when the valve closes/ switches direction.
