CHANNEL: Choose to use a single control loop (choose "Single") or a control loop with 2 outputs, each with a
set of parameters (choose "Dual").
"Dual" mode is used, for example, to control the pH with an acid output and a base output: when the "acid"
output is controlled, the "base" output is at zero and vice versa.
