Honeywell Thermostats TCC for Crestron Home™ driver

It is recommended that you save a configuration or golden configuration before installing any driver.

The concept of the instance number is the same as how it’s used in the Crestron SIMPL HVAC Scheduler module. The instance number is used to create a unique filename on the processor so that it stores the token information needed to make requests. In normal circumstances you can leave it as one. You would need to change the instance number if the thermostats were paired to separate user accounts and you wanted to provide them access to thermostats from both accounts. An example of this is if the main house thermostats are paired to one user account and the guest house thermostats are paired to a separate user account. If you want thermostats from both properties to show up, you would need to add 2 instances of the platform driver, and each instance would need a unique instance number to work properly.

The delay in drivers loading is attributed to the platform driver, which requires a minimum of 20 seconds to establish its drivers following a system reboot. This duration is essential to ensure synchronization with the processor's readiness for optimal functionality.

If the driver doesn't create the directory with the zone list, there are a few steps you can take to troubleshoot the issue:

• Verify the Location name: Ensure proper directory creation, confirm that you're using the exact location name (case-sensitive) used during the initial thermostat pairing with the user's Honeywell account, as the driver is sensitive to case and accuracy. If you're uncertain about the name, consult Honeywell’s documentation, user manual, or reach out to their support team for assistance. When you are getting the authorization code you can see the available locations to be used.

• Unpair and pair the thermostat: If you don't remember the location name or suspect that it might be incorrect, you can try un-pairing and re-pairing the thermostat again on the user's Honeywell’s account. This process typically involves accessing the settings menu on the thermostat and selecting the unpair or disconnect option. Once unpaired, follow the instructions provided to pair the thermostat again with the correct location name.
• Allow time for communication: After adding the thermostat to a room, it's important to wait for a sufficient amount of time for the driver to establish communication with Honeywell’s service. In some cases (especially systems with a large number of thermostats), it may take at least 1 to 2 minutes for the driver to properly communicate and create the directory with the zone list.
• The authorization code has a very short expiration time (approximately ~1 minute). Use a private browser tab if necessary. Many people obtain the authorization code first and then slowly go through the process to install the driver. Instead, go through the process of installing the driver and enter in all other information (license key). Then go through the process to obtain the authorization code and location name. Once you obtain that info, put it in the driver and proceed. The folder may not appear if the authorization code has expired or is invalid. Please note that the code is only valid for 1 minute and can be used only once. Avoid using the back button on your browser to request a new code.

If after all these steps the folder is still not showing up, then you may contact us via email. We may ask you to send us the user’s account credentials in order to properly troubleshoot the issue.

Unfortunately yes, if you add thermostats, you have to go through this process again. This is a security feature from Honeywell. The authorization only allows you access to the thermostats that have been allowed. Since the newly added thermostats were not allowed, the driver can’t get access to it. The process is similar to updating the driver. First, make sure you check the option to delete the configuration file in the driver’s Installer Setup option. Then uninstall the driver. If you don’t check the option to delete the configuration file, it will just pick up the old (now stale) authorization data and the new thermostat won’t show up. It’s recommended that you wait until all the thermostats have been installed before going through the process of getting them to work with this driver.

Not necessarily, when you first install the driver and enter the authorization code, if it’s successful, it will create a config file on the processor. This config file will remain on the processor unless you manually remove it. When you install a new version of the driver, leave the authorization code empty and it will automatically pick up the file and use the information in there to make its request. It is important that the instance number matches the previous driver.
