Honeywell Pro Series Thermostat

How do I set up a heating and cooling schedule on my Honeywell Pro Series thermostat?

To set the schedule, press the Menu button and select 'Program.' For each mode (Heat or Cool), set the temperature and time for Wake, Leave, Return, and Sleep time blocks using the arrow keys. After setting the weekday schedule, set the weekend schedule separately. Press 'Done' or 'Run Schedule' to save your settings, and the thermostat will follow the programmed schedule.

Why is my Honeywell thermostat showing a 5-minute delay and not cooling?

When the thermostat blinks 'Cool On' while set to cool, it typically means the system is in a 5-minute delay mode to protect the compressor. Wait 5–10 minutes to see if cooling starts. If the system still doesn't cool, try turning the thermostat off, removing and reinstalling the batteries, then setting it to cool again. Also ensure the circuit breaker is on, the furnace door is closed, and the power switch is on.

Why does my Honeywell Pro Series thermostat increase the temperature on its own?

The thermostat may automatically increase temperature due to the Adaptive Intelligent Recovery (AIR) function, which learns how long it takes to reach the desired temperature and starts heating or cooling in advance to ensure comfort at the scheduled time. This function is enabled by default but can be disabled through the Menu settings if needed.

How do I remove a permanent or temporary hold on my Honeywell thermostat?

To remove a permanent hold, press the 'Run' button to cancel the hold and return the thermostat to its normal programmed schedule. To erase a temporary hold specifically, press the 'Cancel' button to remove the hold and return the thermostat to its scheduled program.

How do I change the batteries in my Honeywell Pro Series thermostat?

How do I switch my Honeywell thermostat to heating mode?
