*INSTALL NOTE: For optimum temperature sensor performance, the Bard CompleteStat
TM
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 CO
2
-Sensing CompleteStat™,
and a vertical-only 2x4 wall handybox can be used for Non-CO
2
-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.
