Fresh Air Ventilation
A fresh air ventilator is used to exchange stale indoor air for fresh
outdoor air. Fresh air ventilation can be customized with up to four
settings. The setting you choose for heating operation can be differ-
ent from the setting you choose for cooling.
HIGH: The fresh air ventilator will operate at high. This setting is rec-
ommended to help quickly remove unwanted odors.
LOW: The fresh air ventilator will operate at low continuously. This
setting is recommended for continuous operation in mild climates
with low humidity.
AUTO: The system will automatically vary the fresh air ventilator
speed to accommodate outdoor seasonal conditions and desired
indoor humidity and temperature settings. This setting is recom-
mended for cold, northern climates.
DEHUM: The system will operate the fresh air ventilator only if dehu-
midification is necessary. This setting is only available in heating.
Refer to the BASIC SETUP section of this manual to select your
fresh air setting. Please note that a fresh air setting will only appear
if a ventilator has been installed.

Questions and answers
heat button won't turn on
The heat button on the Carrier Infinity Control may not turn on due to several reasons:
1. System Mode – Ensure the thermostat is set to "HEAT" or "AUTO" mode. If it's in "COOL" mode, the heat button will not activate.
2. Temperature Setting – The set temperature must be higher than the current room temperature for heating to turn on.
3. Emergency Heat Mode – If the system is in emergency heat mode, the red HEAT button may behave differently.
4. LED Indicator – If the red LED adjacent to the HEAT button is not lit, the heating function may not be active.
5. System Malfunction – If the system is not responding, there may be an issue with the thermostat or HVAC system, requiring professional inspection.
