Step 3

RUN THE REQUIRED WIRES (SEE ILLUSTRATION 2)

1.Run thermostat cable from each thermostat to the appropriate HVAC system or zone control panel. Use 4 through 8-conductor thermostat cable depending on the type of equipment and number of equipment stages. Run one more wire than would be required if connecting to a mechanical thermostat.

If you are using remote temperature or humidity support modules as part of your installation, now is the time to run the additional wires for these items. A separate Category 5 cable must be run from thermostat to support module.

2.At the HVAC/zone control system, use a piece of tape to label the location of the thermostat on the cable as you go.

3.Run Category-5, 4-pair twisted cable (8-conductor) from each thermostat to the Distribution Panel.

4.At the Distribution Panel, use a piece of tape to label the location of the thermostat on the cable as you go.

5.Run Category-5 wire from the Distribution Panel to the Protocol Adapter. If more than one Distribution Panel is used, run Category-5 wire between each panel.

6.Run two-conductor thermostat cable from the

Model 8027 Transformer to the Distribution Panel. You can use Category-5 wire, but you must use one pair of wires per terminal.
