Step 4

LOCATE AND MOUNT THE AUTOMATION SYSTEM COMPONENTS

1.Thermostats and sensors are to be located according installation instructions provided with the units. The thermostat has four configuration dip switches on the circuit board that must be set according to the equipment the thermostat will be controlling. Sensors have six configuration dip switches that must be properly set. The installation manuals provided with the products detail how the switches are to be set.

Review the Network Interconnection Worksheet (ILLUSTRATION 3) which shows how all the

communication components are connected together and ✍write down the location of, or a name for, each thermostat in the system. This will assist in the software

set-up. Additional copies are available in the back of this manual.

✍IMPORTANT!

THE FEW MINUTES SPENT WRITING DOWN

THE INFORMATION SUGGESTED IN THESE STEPS WILL SAVE A TREMENDOUS AMOUNT OF TIME DURING THE REST OF THE INSTALLATION.

2.Mount the zone control panel(s) if the HVAC system(s) is zoned. Refer to the zone control panel installation instructions.

3.The Aprilaire Distribution Panel must be mounted indoors in an accessible location such as a closet or utility room. All thermostats will be wired to the Distribution Panel, so adequate workspace will be important. There are wire access holes on the top, bottom, sides and back of the Distribution Panel.

4.The Model 8811 Aprilaire Protocol Adapter must be placed within six feet of the host computer or RS-232 port of the automation system. The Protocol Adapter does not get fastened down. All the cables and connectors needed to attach the Protocol Adapter to the computer or automation system are included with the adapter.

5.The Model 8027 Plug-in Transformer is used to power the communication system. The transformer is wired to the Distribution Panel. Locate this transformer in the same space as the Distribution Panel if possible.
