Technical specications

FH-WC is a wiring center for connecting up to
10 thermal actuators to the room thermostats.
It is provided with two potential-free relays for
controlling a circulation pump and a boiler. The
relays are activated when one or more thermo­stats require heat.

FH-WC is connected to 230 VAC/50 Hz.

Mounting is made easy due to the symbols
printed on the screw terminals.

FH-WC is a connection box for use in hydronic
oor heating systems supplied from a manifold.
