Why do thermostats have locking features?

The "lockout" feature is a relatively new invention in thermostats, even those from companies like Honeywell. The reason they were invented was simple: no one wants anyone messing with the thermostat. Instead of having to be constantlyReset your thermostatWhen the temperature is optimal, you can lock it so that your children cannot access it.

Are locking features available on all Honeywell models?

If you don't like the idea of ​​a locking feature on your thermostat, you're not alone. The good news is that you don't have to buy a Honeywell thermostat with a lockout feature. There are many Honeywell branded thermostats that do not have a lockout feature. If you don't have children, getting a non-locking thermostat is highly recommended.

That being said, all are Wi-Fi compatibleHoneywell-Thermostatehave a blocking function. So if you don't want to keep your screen locked, just unlock it and keep it unlocked.

When does it make sense to lock the thermostat?

The decision to lock the thermostat is often a situational matter. If any of the following apply, you should lock your thermostat:

  • You own a building used by multiple clients and you have the legal right to control the temperature.If you own an office, consider keeping it closed to save on costs. The same applies to the thermostats used in the common areas of the apartments.
  • You have children who like to play with the thermostat.Trust me, I know this pain well. I was a kid who wanted to play "super spy" by unlocking a secret code on a safe that was really just a thermostat on the wall.
  • You have an Airbnb.Most states allow you to lock the thermostats in an Airbnb. I don't think anyone will accuse you of making the switch to save money.

How to find instructions on how to unlock your Honeywell thermostat

In fact, most Honeywell lockable models also have specific unlocking instructions. The easiest way to find out how to unlock your specific model is to consult the instruction manual for the specific type of thermostat you have. If you are unsure of the model number of your thermostat, refer to the thermostat identification plate on the back of the thermostat.

If your owner's manual gives you different instructions than those listed here, simply follow the instructions in the owner's manual instead of those listed here. The guidance in your manual surpasses any other guidance you may have.

Can you change the access code for your thermostat?

Here's the odd thing about many of Honeywell's lockable thermostats: you can't actually change the access code that's set by default. So while you can lock your screen with a passcode, pretty much anyone who knows the default setting can change the temperature regardless of your intentions.

Why can't you change the access code for your thermostat?

To be honest we don't know. Some people suggested that this was Honeywell's method of ensuring you can change hands without locking out the new owner of your thermostat. Others have suggested that it's easier to program this way, or that it's a way to fail-safe set up a thermostat.

Should you always keep your thermostat unlocked?

While this largely comes down to personal preference, the truth is that most people don't need their thermostat locked most of the time. Most people don't bother turning up or changing the thermostat. If you have a home with a group of adults who can hear the rules, there's no reason to leave the thermostat locked.

What do the lockout settings on a Honeywell thermostat mean?

If you've been looking at the display, you've probably noticed that most Honeywell thermostats have three lock settings instead of two. Here's a summary of what each setting does:

  • IN.This activates all the features of a screen lock, meaning your thermostat can only be changed when you unlock it.
  • OUT OF.As the name suggests, this disables all features that come with the lock screen feature. If your lock is set to "OFF" anyone can change any setting that came with the thermostat.
  • PARTIALLY.You just have to have itsomeAre functions of your thermostat blocked? In this case, select this option. This gives users a little wiggle room to change some settings, but it doesn't give the thermostat a free hand.

If you have a faulty thermostat, try swapping the batteries to see if that helps. If it doesn't and you can't find a solution online, contact Honeywell Support. They are great for troubleshooting problematic thermostats.

What type of Honeywell thermostat do I have?

If you don't have the card handy, you can check the model number on the nameplate on the back of your thermostat. Once you get the model number, you can look up your model number online and get the full details of your model.

How can I tell if my Honeywell thermostat is working?

A working thermostatwill have an illuminated LED displayand it changes the temperature of your room according to the commands you send it. If you don't see any signs of lights, no sign of current flowing through the thermostat, or you just don't feel a change in temperature, you probably have a faulty thermostat. Make sure it works and then troubleshoot to fix it.
