The Zone Control Module is designed for use with Uponor Thermostats, Motorized Valve Actuators (MVAs),
Thermal Actuators or Zone Valves. The Zone Control Module provides connection between the thermostats
and their respective actuators or zone valves; and the connection between the end switches and the pump
or boiler relay. The modules are internally fused for protection from over current or direct shorts from the
power supply transformer. The end switch circuit is also protected from over current, and a 2 amp fuse is
factory installed.

The Powered Four- and Six-zone Controllers include transformers for low-voltage operations and relays to
operate line-voltage controls. Fully fuse-protected, they also include an isolated end switch and built-in
DHW priority switch. The indicator lights show full functionality of the products wired to the Powered Zone
Controllers. A 3-amp delay fuse protects the Powered Four-zone Controller. A 7-amp delay fuse protects
the Powered Six-zone Controller.

The Motorized Valve Actuator (MVA) (24VAC) features quick-opening motorized valve head that mounts
directly onto TruFLOW Valved Manifolds. The open/close indicator allows for easy visual inspection. It
provides individual fl ow control on a multi-zoned manifold (manifold serving more than one zone). MVA
includes end switch for activation of relay (pump), heat plant or other auxiliary devices. Do not mount
actuators upside down.
