TEKMAR 316 - Control Description The tekmarNet®4 (tN4) Wiring Center 316 is designed to operate up to four zone pumps in a hydronic heating system. It provides a convenient location to wire both thermostats and zone pumps while only requiring two wires to integrate with the rest of the mechanical equipment. The 316 is optimized for use with tekmarNet®4 Thermostats. These thermostats communicate with the tN4 Wiring Center to provide a synchronized end switch that reduces cycling of equipment.
