The Decision Making Process ( P. 1 )

• Decisions are made by the UCP, not the device on
  the wall.
• 9x 9 board, same location in all units.
• DDC control, better space temp. control.

3
Increased Reliability

• Fewer Components and moving electromechanical
  parts.
• Less likelihood of equipment down time or
  failure.
• Standard on Voyager Microcontrol units.

4
Direct Digital Control Proportional Integral (
P. 1 )

• P is corrective action proportional to the
  setpoint deviation.
• I is an integral fine tuning loop, rate of
  correction is proportional to error.
• Eliminates steady state error, providing superior
  comfort.

• Tests UCP outputs
• Initiated by applying a short across TEST
  terminals on unit LTB for 2 - 3 seconds and then
  removing.

  unit is in the TEST mode.

TEST Terminals
6
