The tekmarNet® 2 Wiring Center 313 is designed to provide a zoning solution for heating systems. It can be used in applications ranging from baseboard zones, to remote manifolds for radiant heating. This product provides power for up to four tekmarNet ® 2 thermostats, and up to four 24 V (ac) zones valve outputs, as well as providing an end switch closure to enable an external device such as a boiler. A line voltage output on the back of the control can operate a zone group pump if required. An outdoor sensor input is included and provides the outdoor air temperature reading on each thermostat when an optional outdoor sensor is installed.
