INSTALLATION AND
OPERATION INSTRUCTIONS
PRECAUTIONS
CAUTION
!
To prevent electrical shock and/or equipment damage,
disconnect electric power to system at main fuse or
circuit breaker box until installation is complete.
This thermostat is intended for use with a low voltage system;
donotusethisthermostatwithalinevoltagesystem.Ifindoubt
aboutwhetheryourwiringismillivolt,line,orlowvoltage,have
itinspectedbyaqualiedheatingandairconditioningcontrac-
tor or electrician.
Donotexceedthespecicationratings.
Allwiringmustconformtolocalandnationalelectricalcodes
and ordinances.
Thiscontrolisaprecisioninstrument,andshouldbehandled
carefully. Rough handling or distorting components could cause
the control to malfunction.
WARNING
!
Do not use on circuits exceeding specified voltage.
Higher voltage will damage control and could cause
shock or fire hazard.
Do not short out terminals on gas valve or primary
control to test. Short or incorrect wiring will damage
thermostat and could cause personal injury and/or
property damage.
Thermostat installation and all components of the sys-
tem shall conform to Class II circuits per the NEC code.
Operator: Save these instructions for future use!

INSTALLATION
REMOVE OLD THERMOSTAT
1. Shutoffelectricityatthemainfuseboxuntilinstallationis
complete.Ensurethatelectricalpowerisdisconnected.
2. Removethefrontcoveroftheoldthermostat.With wires
still attached, removewallplatefromthewall.Iftheold
thermostathasawallmountingplate,removethethermostat
andthewallmountingplateasanassembly.
3. Identify each wire attached to the old thermostat using
the labels enclosed with the new thermostat.
4. Disconnectthewiresfromoldthermostatoneatatime.DO
NOT LET WIRES FALL BACK INTO THE WALL.
5. Installnewthermostatusingthefollowingprocedures.
ATTENTION!

of the thermostat.
• SIMULTANEOUS HEATING/COOLING SETPOINT STOR-

• CONFIGURATION MENU — Allows you to customize
certain thermostat options.
SETTING THE THERMOSTAT
This thermostat is very easy to operate. Set the SYSTEM
switch to either HEAT or COOL then press
or until the
temperature you want to maintain is shown on the right side
ofthedisplay.Ifyouwanttoturnthesystemoff,justmovethe
SYSTEMswitchtoOFF.
The FAN switch controls the fan operation. When the FAN
switch is set to AUTO,thefanwillcyclewiththefurnaceorair
