CENTRAL COMMAND II
The Central Command II control system implemented on majority our machines in Septem-
ber of 2002. This new control system utilized a controller Manufactured by P&G Drives of 
the UK. The new P&G controller is feature-rich and simplified our control systems.

easily identifiable by the LCD display on the control panel. 
All machine that are equipped with Central Command II 
have this display. The display is the same on all of our 
machines and is fully interchangeable from machine to

CONTROLLER IDENTIFICATION
To date of this publication we have used 3 versions of the P&G controller. These versions 
are easily identifiable. The V.2 (Trio) and V.3 (Trio +) controls can be identified by unplug-
ging any of the high amperage output plugs; Brush, Vacuum, Traction. When the plug is 
out. Look down into the cavity of the controller that the plug was in and note the color of 
the circuit board. If the circuit board is GREEN the controller is a V.2 (Trio). If the circuit 
board is BLUE the controller is a V.3 (Trio +). If the controller has 8 lug terminals across 
the front and NO high amperage plugs the controller is a V.4 (Trio + HD).
