Installation

NOTICE

Hazardous Voltage!

Disconnect allelectric power, including remote
disconnects beforeservicing. Follow proper
lockout/tagout proceduresto ensure the powercannot
be inadvertentlyenergized. Failure to disconnectpower
before servicingcould result in deathor serious injury.

NOTICE

Equipment Damage!

Applying excessive voltageto the thermostat will
permanently damage it.

To mountthe backplate:

1. Shut offthe power to allHVAC equipment. If the
security screwis used, remove it.Refer to the
illustration.

2. Pushthe coverthumb tabtorelease thecover fromthe
backplate asshown.

3. Route the wires throughthe openingin thebackplate.
Wires shouldbe markedto ensure properconnection
to terminals.

4. If mountingthe backplate directly toa wall surface,
hold thebackplate against the surfaceand then level
and markthe fastener locations.

5. Securethe backplateusing appropriatefasteners. The
thermostat shouldbe mounted level andplumb for
best airmovement through thethermostat enclosure.

6. Locate theterminal blocks from thepackaging (new
installation) orremove from pin header(existing
installation).

7. Connectthe wiresto theterminalblocks andthenpush
the terminalblocks onto the circuitboard pins.

8. Pushexcess wirethrough thehole inthe wallcavity or
into thejunction box.Do notcoil excesswire between
the thermostatand the backplate.

Configuration

NOTICE

Adverse Control System Behavior!

Improper configuration setupcould cause unwanted,
possibly adverse control system behavior. Be sure to
configure the thermostataccording to your system type.

To changethe installation configuration:

1. Apply electricalpower to the thermostat.

2. Determine theconfiguration options andthen write down the
selections orother notes on thetable in Panel 6.

3. To activateConfiguration Option Setup mode:

WARNING

Live Electrical Components!

The circuitboard isenergized. Have aqualified licensedelectrician
or otherindividual who hasbeen properly trainedin handling live
electrical componentsperform this step. Failureto follow all
electrical safetyprecautions when exposed tolive electrical
components couldresult in death orserious injury.
