Chapter 4: Programming the Plus Touch

Programming equipment settings
Programming the stages means entering the settings such as set points, idle speeds, ON/OFF times
and durations, and so on.

Programming merged ventilation
Merged mode uses up to four steps. Each step has a temperature range for the equipment that
operates during the step. Each type of ventilation equipment has its own settings for each step. One
of the benefits of merged mode is that it can provide smoother transitions between steps than
staged mode can between stages.
The following example includes two variable stages, one fixed stage, and inlets.

Each step’s start and end temperatures define the range of the step. The equipment columns
(variables, fixed, and inlets) show the settings during the step.
As the temperature rises or falls within a step, the speed of variables and position of inlets will
increase or decrease proportionally; fixed stages will be at their assigned state. When the temperature
rises above or falls below the range for a step, Plus Touch uses the next step. In the example above,
when the temperature is 74.5°F, Plus Touch uses step 2. When the temperature rises over 75°F, the
control uses step 3.
