Mounting
Contents
1. Complete rough-in wiring at each location prior
to the FlexStat’s installation. Cable insulation
must meet local building codes.
CAUTION
To prevent mounting screw heads from touching
the circuit board in the thermostat, use only the
mounting screws supplied by KMC Controls.
Using other screws may damage the FlexStat.
Do not turn screws in farther than necessary to
remove the cover.
2. If the cover is locked on the backplate, turn the
hex screws in the bottom and top of the FlexStat
CLOCKWISE
until they (just) clear the cover.
(See Illustration 1.) Pull the cover away from the
backplate (mounting base).
3. Route the wiring through the backplate.
4.
With the embossed “UP” and arrows toward the
ceiling,
fasten the backplate to a wall electrical
box. This FlexStat mounts directly on
vertical
2 x
4 inch boxes but requires an HMO-10000W wall
mounting plate for horizontal or 4 x 4 boxes.
5. Make connections to the terminal blocks. (See
Connections and Wiring on page 5
6. Push the FlexStat cover over the backplate
while
being careful not to pinch or dislodge any
wiring
. Back the hex screws (
counterclockwise
)
out of the brackets until they engage the FlexStat
cover and hold it in place.
