Expanded mode
In the heating-cooling control (expanded mode), mix control (expanded mode), or position proportional control (expanded
mode), the number of loops for the heating-cooling control or position proportional control can be expanded using an output
module and others in the system. To use an expanded mode, construct a system such as the one shown below.
