The tekmarNet
®
4 Wiring Center 35 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 control energizes up to 6 zone valves. It is capable of providing
power for up to 6 tekmarNet
®
4, or stand alone thermostats, and energizing their respective 24 V (ac) zones, as well as providing an
end switch closure to enable an external device such as a boiler.
