This equipment has been tested and found to comply with the limits for
a Class A digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions in this manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.

Be sure that all products from Andover Controls Corporation is
grounded to true earth ground. This kind of ground protects the
equipment from lightning strikes and other power surges in the area.
We cannot guarantee that the controller system will operate as
documented unless you properly grou nd all control lers .

Be sure to have your grounds inspected before you begin the

substandard electrical grounds.
An example of a substandard ground is a galvanized steel cold water
pipe. As the pipe corrodes, it does not act as a true ground. The corrosion acts as an insulator, raising the potential of the pipe with respect to
the ground.
When lightning strikes in the area of the ins talla tion, it drastically
changes the potential of the earth.
Surges of much lower potential also impact the reliability of Andover
Controls equipment.
Since properly grounded Andover Controls units respond to changes in

potential more rapidly than poorly grounded electrical systems, a poorly grounded building tries to reach ground through the Andover
Controls system. The surge of current can destroy electronic components on the controller board.
Inspecting the Ground
You can check your ground as follows:
1. Check your ground by first inspecting the building power
distribution panel for earth ground termination. If the ground
termination is any of the following, it is not adequate and must be
corrected:
• Does not exist.
• Is connected to a corroded or galvanized pipe.
• Is connected using a small gauge wire (smaller than 14 AWG).

5. Inside, find the jumper wire to the right of the heat sink. It is labeled

6. To switch from 115 V to 230 V, remove the jumper and move it
down one pin. Placing the jumper in the 230 V position effectively
disconnects it, but keeps it in a safe pl ace if you ever want to switch
back.
To switch from 230 V to 115 V, remove the jumper and move it up
one pin.
7. Check to be sure you have the correct fuse. The fuse is on the far
right side of the printed circuit board in approximately the verti cal
center.
