Rotation and Switch Network Input modules are directly connected to Output Control modules in Central Heating Applications, Central Cooling Applications, or Central Cooling with Optimization Applications, unless otherwise indicated. The primary use of Rotation modules is to immediately recalculate the equipment starting order. You can command this input for manual rotation, or you can schedule it for automatic rotation. The primary use of Maintenance Switch modules is to stop equipment from running during repairs or maintenance. You can command Switch modules ON to put a piece of equipment out of service. This action results in stopping the equipment if it is running and taking it out of the rotation sequence until you command the maintenance switch OFF.
The following table describes the Rotation and Switch Network Input modules and lists the applications in which they are used.
