LK 525 MultiZone 3R is a 3-way valve that can be used as a mix-
ing valve or as a diverting valve in heating systems.
The valve is constructed so that the leakage is less than 0.1% of
Kvs at 100 kPa. It also has a split linear characteristic which means
that the regulation is good even at low flows and capacities.
The valve must not be installed with the motor underneath the
valve unit. Please note that the motor can be installed in only
one position.
The motor operates anti clockwise when the black conductor is
powered and clockwise when the brown conductor is powered.
