The tekmarNet ® 4 (tN4) Wiring Center 315 is designed to
operate up to six zone valves in a hydronic heating system.
It can be mounted near a remote zone manifold, providing a
convenient location to wire both thermostats and zone valves
while only requiring two wires to be run back to the mechanical
room. When combined with tekmarNet
® 4 Thermostats, all
devices communicate to provide a synchronized end switch
that reduces cycling of equipment. A zone group pump
relay is also available to switch a pump.
