The tekmarNet
®
2 Zone Manager 334 is designed to provide a zoning solution for 2-wire tekmarNet
®
2 thermostats used in heating
systems. It can be used in applications ranging from baseboard zones, to remote manifolds for radiant heating. This control energizes
up to 4 zone valves or zone pumps. It is capable of providing power for up to 4 tekmarNet
®
2 thermostats and energizing their respective
24 V (ac) or 5 V (ac) zones, as well as providing a powered Zone Group Pump (powered end switch) contact to enable an external
device such as a manifold pump.
