*INSTALL NOTE: For optimum temperature sensor performance, the Bard CompleteStatTM must be mounted on an
interior wall and away from any heat sources, sunlight, windows, air vents, air circulation obstructions, and/or any other
cause of erratic or false temperature sensing.

Controller Installation: Mounting Controller

1. Complete rough-in wiring using a minimum 18 AWG solid-conductor control wiring, see Low Voltage Wiring

Diagrams in this Manual for exact number of conductors.

2. Turn the hex screws in the bottom and top of the controller clockwise (inward) until they clear the cover.

Remove base plate from controller.

3. Route completed wiring through base plate.

4. With the embossed “UP” arrows of the base plate pointing in the appropriate direction, fasten the base plate to

the desired wall location. A vertical/horizontal 2x4 wall handybox can be used for CO2-Sensing CompleteStat™,
and a vertical-only 2x4 wall handybox can be used for Non-CO2-Sensing CompleteStat™.

5. Make appropriate control wire connections (see Low-Voltage Wiring Manual) to terminal blocks.

6. Replace controller over base plate, being careful not to pinch/dislodge connections.

7. Turn hex screws in bottom/top of controller counter-clockwise (outward) to secure cover.

8. Enter button again to select/enter Aux Heat

9. Enter button again to highlight Aux Heat choices

10. Up/Down buttons to toggle through available choices…
 W/O Lockout – Auxiliary heat will activate regardless of compressor operation or outdoor air temperature (factory default)

- If W/O Lockout is chosen, proceed to set delay-on time

 Comp Lockout – Compressor locks out below the selected Outdoor Air Temperature. (Requires optional 8301-

061 Outdoor Air Temperature Sensor.)

 None – no auxiliary strip heat, controller will not energize W2

- If None is chosen, Left button (5x) to return to home screen

11. Down button to highlight Delay (mins)

12. Enter button to highlight default Delay minutes

13. Up/Down buttons to select the amount of minutes you would like to delay the electric heat before activation.

14. Enter button to save choice.

15. Left button (5x) to return to home screen.

Compressor Lockout Temperature – If you have chosen auxiliary heat strip configuration “Comp Lockout,” an
optional outdoor air temperature sensor will have to be installed/configured to specifically set the temperature at
which the compressor will no longer be allowed to operate. To install the 8301-061 Outdoor Air Temperature
Sensor, attach the leads to terminals “OAT” and “GND.” To set the compressor outdoor air temperature from
the home screen, press…
