boiler regulation or from a timer. at closing the inputs X16
the complete boiler will be heated up to 65° C.
Warning: in order to avoid the increased danger of
scalding it is recommended to install a cold water mixing
plant.
additionally to the external activation there is also the possibility to enable the legionella circuit via an integrated time
switch.
