the LCD display and use the controls. If the built-in temperature sensor is being used to measure room temperature, place
the thermostat where the temperature is representative of the general room conditions. Avoid cold or warm air drafts,
radiant heat, and direct sunlight.
WARNING
: Risk of electric shock and property damage. Disconnect power supply before making electrical
connections. The installation is to be performed by a qualified electrician.
WARNING

precautions.
