The tekmarNet 4 Wiring Center 316 is designed to provide a zoning solution for heating systems. It can be used in applications ranging from baseboard zones, to radiant heating zones. This control energizes up to 4 zone pumps. It is capable of providing power for up to 4 tekmarNet ® 4 or stand alone thermostats and energizing their respective 115 V (ac) zones, as well as providing an end switch closure to enable an external device such as a boiler.
