Technical specications
FH-WC is a wiring center for connecting 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 has 8 available outputs.
FH-WC is connected to 230 VAC/50 Hz.
Mounting is made easy due to the symbols
FH-WC is a connection box for use in hydronic
oor heating systems supplied from a manifold.
