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) zone 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.
SPECIAL REQUIREMENTS
This control is designed for use ONLY with tekmarNet
