The regulator is equipped with a specific mechanism allowing circulation
independently of the action of the thermostat.
Used for thermal disinfection of the circuit.
The by-pass mechanism operates manually by simply removing the black
protective cover. By installing the thermoelectric actuator it is possible to
govern the mechanism automatically.
To make sure that the valve is in the open position when putting the
system into operation, the actuator is supplied in the normally open (N/O)
position and stays in this position until it is powered up for the first time.
Screw the red adapter fully down on the thread of the valve body and
couple the thermoelectric actuator onto the adapter.
To remove the actuator, press the release button on the cover and pull it
towards yourself.

Maintenance La cartuccia preassemblata
contenente i componenti di
regolazione può essere rimossa dal
corpo valvola per eventuale controllo,
pulizia o sostituzione.
The preassembled cartridge
containing the control components
can be removed from the valve body
for inspection, cleaning or
replacement.
Il corpo valvola è dotato di attacchi
per il collegamento di prese di
pressione/temperatura, per la verifica
delle perdite di carico e delle effettive
temperature nel circuito.
The valve body is equipped with
connections for fitting with
pressure/temperature ports in order to
check head losses and actual
temperatures in the circuit.
