The Dual Zone Manager 337 is designed to simplify the wiring between tN4 thermostats and zone valves. The 337 has an
internal transformer that supplies power to the tekmarNet
®
4 (tN4) thermostats and connected zone valves. The 337 has two
tN4 buses with three zones each. The two buses allow the 337 to operate zones on two different water temperatures.
