The tekmarNet
®
2 Zone Expansion Module 324 is designed to provide expansion for a zoning solution used in heating systems. It can
be used in applications ranging from baseboard zones, to remote manifolds for radiant heating. This product expands the number of
zones in a heating system by 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.
