When Heat On or Cool On is flashing, compressor protection is engaged (see page 14).
Set the time and day
- Press the SET button, then press it to set the clock time.
- Press the SET button, then press to select the day of the week.
- Press RUN to save & exit.
Note: If the clock flashes, the thermostat will follow your settings for the Monday “Wake” time period until you reset the time and day.
Select the system setting
The SYSTEM switch can be set to control your heating or cooling system, depending on the season.
- Cool: Cooling system control.
- Off: All systems are off.
- Heat: Heating system control.
- Em Heat: Emergency & Auxiliary Heat control. The compressor is locked out. (Select models only.)
CAUTION: EQUIPMENT DAMAGE HAZARD.
To prevent possible compressor damage, do not operate the cooling system when the outdoor temperature is below 50°F (10°C).
Select the fan setting
- Set the FAN switch to Auto or On.
- In “Auto” mode (the most commonly used setting), the fan runs only when the heating or cooling system is on.
- If set to “On,” the fan runs continuously.
Save money by setting program schedules
It’s easy to program your system for maximum energy savings. You can program four time periods each day, with different settings for weekdays and weekends.
- Set to the time you awaken and the temperature you want during the morning, until you leave for the day.
- Set to the time you leave home and the temperature you want while you are away (usually an energy-saving level).
- Set to the time you return home and the temperature you want during the evening, until bedtime.
- Set to the time you go to bed and the temperature you want overnight (usually an energy-saving level).
Energy saving settings for maximum cost savings
This thermostat is pre-set to use energy-saving program settings. We recommend these settings since they can reduce your heating/cooling expenses. (See next page to adjust times and temperatures of each time period.)
To adjust program schedules
- Press SET until Set Schedule is displayed.
- Press to set your weekday Wake time (Mo-Fr), then press SET.
- Press to set the temperature for this time period, then press SET.
- Set time and temperature for the next time period (Leave). Repeat steps 2 and 3 for each weekday time period.
- Press SET to set weekend time periods (Sa & Su), then press RUN to save & exit.
Note: Make sure the thermostat is set to the system you want to program (Heat or Cool).
Program schedule override (temporary)
- Press to immediately adjust the temperature. This will temporarily override the temperature setting for the current time period.
- “Temporary” will appear on the display and the current program period will flash.
- The new temperature will be maintained only until the next programmed time period begins (see page 9).
- To cancel the temporary setting at any time, press RUN.
Program schedule override (permanent)
- Press HOLD to permanently adjust the temperature. This will override the temperature settings for all time periods.
- The “Hold” feature turns off the program schedule and allows you to adjust the thermostat manually, as needed.
- Whatever temperature you set will be maintained 24 hours a day, until you manually change it, or press RUN to cancel “Hold” and resume the program schedule.
Built-in compressor protection
- This feature helps prevent damage to the compressor in your air conditioning or heat pump system.
- Damage can occur if the compressor is restarted too soon after shutdown. This feature forces the compressor to wait 5 minutes before restarting.
- During the wait time, the display will flash the message Cool On (or Heat On if you have a heat pump). When the safe wait time has elapsed, the message stops flashing and the compressor turns on.
Early Start: This feature allows the heating or cooling to turn on before the program start time, so the temperature is reached at the time you set.
For example: Set the Wake time to 6 am and the temperature to 70°. The heat will come on before 6 am, so the temperature is 70° by the time you wake at 6. The next time period is displayed when the system is activated before a scheduled time period.
- Install two fresh AAA batteries when Lo Batt flashes on the screen. Lo Batt appears for 60 days before the batteries are depleted.
- Replace batteries once a year, or when you will be away for more than a month.
- Most settings are stored in nonvolatile (permanent) memory. Only the clock and the day must be set after you replace the batteries.
Set the System switch to Off before removing the batteries. Otherwise, the heating/cooling system could remain activated even when the batteries are removed.

FAQs About Honeywell Pro 2000 Series Horizontal Programmable Thermostat
What is the lifespan of a Honeywell thermostat?
Is it possible to use a Honeywell thermostat without batteries?
Yes, the Smart Thermostat can function without batteries. If no batteries are inserted and the thermostat is powered solely by alternating current, the thermostat will report a low battery (indicated by a caution sign and LOW BATTERY flashing on the display).
Is the Honeywell Pro Series battery-powered?
If the Honeywell T6 Pro Z-Wave Programmable Thermostat was wired to run on 24 VAC power when installed, batteries are not required. Install three fresh AA alkaline batteries as soon as the low battery alert appears to provide optional backup power.
Is the Honeywell Pro Series thermostat battery-powered?
Honeywell thermostats include a low battery warning light. You’ll have about 60 days to replace the batteries once this light turns on.
What’s the deal with my Honeywell Pro Series thermostat not cooling?
Check that the thermostat is set to cool mode and has a cooling set point lower than the room temperature. Check for cooling on the thermostat display, which is usually indicated by the words “cool on” or a snowflake icon. If these icons flash, it means that the thermostat is in delay mode, which can last up to 5 minutes.
What does the Honeywell thermostat do?
It works by sensing the air temperature, turning on the heating when it falls below the thermostat setting, and turning off when the set temperature is reached. Turning up the thermostat in a room will not cause it to heat up faster.
What is the highest temperature that a Honeywell thermostat can reach?
Temperature Range Configuration (F) Heat: 40 F to 90 F; Cool: 50 F to 99 F. Temperature Range Configuration (C) Temperature range: 4.5°C to 32°C; temperature range: 10°C to 37°C. Electrical ratings: 20 to 30 volts or 750 millivolts. The frequency is 50 hertz.
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.
Does the Honeywell thermostat work when the power goes out?
There is no internal battery in this thermostat. All program and installer configuration functions are saved on a chip and retained in the event of a power outage. It does use a supercapacitor for short-term clock retention.
Is it true that all Honeywell thermostats require AC power?
The common wire (C-Wire) delivers continuous power to Wi-Fi thermostats from heating (e.g., furnaces) and cooling systems (e.g. Air Conditioning systems). All Resideo Wi-Fi thermostats require C-Wires.
