Mounting Sub-Base to Wall

Be sure wires are routed through the center of the

base plate and are long enough to connect to ter-

minals.

Select and mark three holes.

NOTE: The three hole locations indicated at right

are recommended. The top location is an optional

mounting screw location.

A level may be used to ensure professional appear-

ance.

Attach base to wall using 3 screws provided. The

locations indicated provide the most secure mount-

ing and are recommended.

NOTE: Since moderate force is required when re-

moving the thermostat from the sub-base, the sub-

base must be securely attached to the wall.

Do not overtighten screws to avoid damaging the

sub-base.

1) Press tip of SnapSkru® an-

chor into drywall using #2 Phillips

screwdriver or screw gun. Drive

anchor clockwise into drywall until

anchor stops flush with wall.

2) Place sub-base over anchor

and insert screw.

3) Tighten screw flush with sub-

base. Screw “pops” open anchor,

locking anchor on wall.

Do not overtighten screws to avoid

damaging the sub-base.

If mounting to drywall, supplied SnapSkru® connectors must be used to mount the thermostat sub-base to

the wall. These connectors will ensure that the control is adequately supported.

NOTE: Since moderate force is required when removing the thermostat from the sub-base, a ﬁrmly mount-

ed sub-base is essential.
