Turn off 24 VAC power at the equipment circuit breaker
or at the system switch. Confirm that power is OFF.
2. INSTALL THERMOSTAT
Position the thermostat base against your wall, and
determine if the accessory wall plate is desired to cover
horizontal 2 x 4 electrical box if installed., if so install
accessory wall plate. Position the thermostat base
against your wall (or wall plate if used) and determine if
the new screw locations align with prior locations. If base
does not align with existing anchor holes, mark new screw
locations with a pencil.
Drywall: Drill 3/16” hole for the anchor
Plaster: Drill 7/32” hole for the anchor
Pull wires through opening in base and secure base
to the wall using provided screws.
