Special functions
Auto Changeover (Setup Function 0300):
When set to Auto, the thermostat automatically selects heating or cooling depending on the indoor temperature. Heat and cool settings must be at least 2 degrees apart. If function 0380 is set to On, the heat and cool settings must be at least 5 degrees apart.
Remote Sensor (Setup Function 0340):
If an optional outdoor sensor is installed, the thermostat can display the outside temperature. If an optional remote indoor sensor is installed, the thermostat will display the temperature at the sensor location (the internal sensor in the thermostat is not used).
Adaptive Intelligent Recovery (Setup Function 0530):
Allows the thermostat to “learn” how long the furnace and air conditioner take to reach programmed temperature settings, so the temperature is reached at the scheduled time.
Compressor Protection (Setup Function 0580): Forces the compressor to wait a few minutes before restarting, to prevent damage. During this time, the message “Wait” flashes on the display. Dehumidification control (Setup Function 0380): TH8321 models monitor the indoor humidity level and automatically activate the cooling system to reduce humidity by lowering the temperature by up to 3 degrees below the current cool setting.
Heat Pump Temperature Lockout (with fossil fuel backup):
If the thermostat is installed with an optional outdoor sensor, you can select a compressor lockout temperature (Function 0350). When the outdoor temperature is below the lockout temperature, only the auxiliary heat operates. When the outdoor temperature is above the lockout temperature, only the compressor operates.
Heat Pump Temperature Lockouts (with electric heat backup):
If the thermostat is installed with an optional outdoor sensor, you can select a compressor lockout temperature (Function 0350) and/ or an auxiliary heat lockout temperature (Function 0360).
When the outdoor temperature is below the compressor lockout temperature, only the auxiliary heat operates. When the outdoor temperature is above the auxiliary lockout temperature, only the compressor operates.
If the outdoor temperature is between the compressor and auxiliary lockout temperatures, both the compressor and auxiliary heat can operate.

FAQs About Honeywell VisionPRO TH8000 Series Programmable Thermostats
Is there a battery in the Honeywell VisionPRO 8000?
Batteries: Three AAA alkaline batteries that can be replaced: When the 24-volt common is not used, power thermostats.
How do I program my Honeywell thermostat?
Setting the temperature on your Honeywell thermostat is simple if you have a manual thermostat. To adjust the temperature, simply press the up and down buttons. The temperature you set will remain until you change it again.
What happens if the Honeywell thermostat battery runs out?
A dead set of batteries renders your programmable thermostat inoperable, preventing you from controlling your HVAC system. You’ll also lose the pre-programmed settings on your thermostat. You’ll have no choice but to change the batteries if you get this far.
Is the Honeywell 8000 capable of controlling humidity?
To control humidification, dehumidification, or ventilation, use the VisionPRO 8000 thermostat, wall anchors, screws, and universal IAQ contacts.
What is the definition of Honeywell thermostat cycles per hour?
A cycle rate is the number of times a system will run in an hour at 50% capacity to maintain a given temperature. A cycle rate of 3 is recommended for high-efficiency (90%+) gas or oil-forced air systems. This means that the heating system will cycle no more than three times per hour.
What apps are compatible with Honeywell thermostats?
Users can use the Honeywell Total Connect Comfort app to remotely monitor and manage their heating and cooling systems at any time and from any location.
How do I change the setting on my Honeywell thermostat to automatic?
When it says “auto cool,” you must first press the mode button until the mode changes to “heat,” then use the + or – to change the heat set-point. Then, press the mode button to return to Auto Changeover mode.
How do you set a Honeywell thermostat manually?
Switch between fan-only, cooling, and heating modes by using the thermostat’s buttons. The temperature can be adjusted using the up and down arrow buttons. To save energy, program or schedule thermostats to work less while you’re away from home. Specific setting instructions can be found in your user manual.
How do I change the temperature on my VisionPro thermostat?
Replace the Thermostat Installing the battery backward for five seconds, pushing a recessed reset button with a pin or paper clip, or turning off the thermostat’s breaker for 30 seconds are all common methods for resetting a thermostat.
