The module is a printed circuit control and diagnostic device designed for use with Wirsbo Thermostats, Motorized Valve Actuators (MVAs), Thermal Actuators or Zone Valves. The module provides connection to the power supply transformer; interconnections between the individual thermostats and their respective MVAs; thermal 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.
Note: The new zone control modules are not able to be ganged with the older modules. The new modules have a black tint base, the old modules have the green tinted base.
