• Always turn off the thermostat before installing, removing, cleaning, or servicing; turn off the power at
the main power source by unscrewing fuse or switching off circuit breaker
• Do not switch to “Cool” if room temperature is below 50°F; this could damage your A/C system and
cause injury
• Do not install on voltages higher that 30 VAC
• All wiring must conform to local and national building and electrical codes and ordinances
• While cleaning, do not get soap directly on thermostat switches or LCD readout; only use a damp cloth
