4. Introduction
The SC-5v2 includes a larger enclosure for easier installation/maintenance, upgraded HHnet protection
circuits, manual natural ventilation controls, and Programming Parameters are included on the front cover
for user friendly reference. The SC-5v2 is designed to be one of the simplest controllers on the market to
operate, but to also be one of the most powerful.
The SC-5v2 has six main regions on the facepad which should be reviewed.
• Main Display and Active Display Indicators
This section includes the Main Display and four Active Display Indicators which tell what the display
is indicating. If the green light beside “Room Temperature” is lit, then the display is showing the
average inside temperature of your building. Later in this manual you will learn about the other three
parameters.
• Variable Speed Status Indicators
Above the stage status indicators, you will notice either one or two variable speed stage status
indicators. These will flash whenever the variable speed stages are on.
• Stage Status Indicators
On the left hand side of the controller face you will see the five stage status indicators (a small red
LED on the left side of this white region). This light will be lit if the stage is on, and will flash on and
off if it is running because it is on a timer. The blank white region is for you to label your equipment
such as (front heat, back heat, sidewall fans, etc.).
