Set the VENT Switch to Auto or On.
Vent Auto is the most commonly selected setting and runs the 
fan only when the heating or cooling system is on.
Vent On runs the fan continuously for increased air circulation 
or to allow additional air cleaning.

Press the SYSTEM button to select:

Calor: Thermostat controls only the heating system.

Off: Heating and Cooling systems are off.

Frio: Thermostat controls only the cooling system.

Auto: Auto Changeover is used in areas where both heating 
and cooling may be required on the same day. AUTO allows 
the thermostat to automatically select heating or cooling 
depending on the indoor temperature and the selected heat 
and cool temperatures. When using AUTO, be sure to set the 
Cooling temperatures more than 1° Fahrenheit higher than 
the heating temperature.

heating system.

thermostat you are replacing or the heat pump being 
installed with this thermostat requires a “B” terminal, to 
energize the  changeover relay in HEAT, the O/B option 
should be set at “B” position.
