Section 2. Control Panel Overview

2.1

Indoor Control Panel

The indoor control panel serves as a means of turning equipment on and off, entering programs to run equipment
automatically at selected times, and displaying what is going on in the rest of the system. Programs (and other
information entered through the controller) are stored in a memory chip on the power center board, even during a
power interruption (however long).
2.2

Controller

The power center supplies the controller 10 VDC via the two (2) outside wires (red and green) of the four (4)
conductor cables. If the voltage drops below 8 VDC, the display will flicker on and off. The two (2) inner wires
(yellow and black) provide the two-way communication link between the controller and the power center. They
communicate via serial communication, using signals like the standard "RS-485".
If either of the communication wires (inner pair) is broken or misconnected, but the power supply wires (the outer
pair) are connected properly, the controller will stop responding. It may show a steady screen of information, and stop
responding to its buttons. If power is then interrupted, the controller will lock up. The way it locks up will depend on
the type of controller.
1. Locked-up All Button. All LEDs will be on and the text will resemble the following: "6700 REV C".
2. Locked-up OneTouch. The screen will be covered with dots, with a line of text that resembles the following:
"Firmware Rev XXX".
2.3

Reset Switch

1. All Button Controller. Pressing the reset switch, located on the left side, will momentarily display the software
part numbers and revision letters for both the controller's micro controller chip and the power center's fi rmware
chip. The reset switch also resets the micro controller, but does not remove any programming, AUX labels, etc.
2. OneTouch Controller. The reset switch can be used to show the revision code for the fi rmware for both the
controller's micro controller chip and the power center's fi rmware chip.
