IMPORTANT SAFETY INFORMATION

WARNING: ELECTRICAL SHOCK HAZARD – Turn off power at the main

power source by unscrewing fuse or switching circuit breaker

to the OFF position before installing, removing, or cleaning

this thermostat.

WARNING: FIRE AND ELECTRIC SHOCK HAZARD – This device should be

installed by a qualified service technician with due regard

for safety as improper installation could result in a fire and

electric shock hazard.

WARNING: FIRE AND ELECTRICAL SHOCK HAZARD – This is a 24V AC

low-voltage thermostat. Do not install on voltages higher than

30V AC.

• Do not switch system to cool if the temperature is below 50°F (10°C). This can

damage your cooling system and may cause personal injury.

• Do not short (jumper) across terminals on the gas valve or at the system control

to test installation. This will damage the thermostat and void the warranty.

• Do not connect ground to any terminal in this unit.

• All wiring must conform to local and national building and electrical codes and

ordinances.

• Use this thermostat only as described in the manual.

become familiar with before programming.

The steps to properly program your SMART 2000 are:

• Determine which type of thermostat (programmable or manual) you have.

• Take the time to write down any temperature settings or start/stop times you

willbeusing,Table1-HeatingandTable2-Cooling.

Commercial: Single setpoint or two setpoints

Residential: Day/night setpoints or seven day with four events.

NOTE: The heat setpoint cannot be set higher than the cool setpoint and the

cool setpoint cannot be set lower than the heat setpoint.

• Review the Common Functions section.

• UsethesectionthatdescribesyourSMART2000(Residential,Commercial,or
