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.

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
