What is the Default Master Code on a Resideo PROA7?

The default Master Code for Resideo PROSeries panels is 1234. This includes the Honeywell Home PROA7 and PROA7PLUS and the Resideo PROA7C and PROA7PLUSC. The differences between the Honeywell Home and Resideo products is mostly cosmetic. Here, we'll show you how to update the Master Code.

The Honeywell Home PROA7 is just one (1) of a series of panels referred to as the PROSeries. This includes the Honeywell Home PROA7PLUS, the Resideo PROA7C and the Resideo PROA7PLUSC. The differences between the Non-PLUS and PLUS versions are numerous and you can view a comparison between them in this FAQ.

Predominantly, the Honeywell Home product line is marketed for residential systems while the Resideo product line is marketed for commercial use. That is why the Resideo panels have the letter C (for commercial) at the end of the panel name. Aside from the branding difference, which you can see in the image below, the major difference between the Honeywell Home and Resideo versions is that the Resideo panels offer the options for arming Away or Stay while the Honeywell Home versions offer the options to arm Away or Home.

The Master Code in the system is second only to the Installer Code when it comes to what it can access. While the Installer Code can be used to enter programming and the Master Code can't, pretty much every other function of the panel can be carried out using the Master Code. It can be used to change itself, and in fact, even the Installer Code cannot change the Master Code without the existing Master Code being entered. This prevents an installer from changing the Master Code without the user's knowledge. At least through keypad programming.

The Master Code has access to add, edit, or delete any user code, with the exception of the Installer Code. The Master Code itself cannot be deleted, only changed. The Master Code also has access to tools such as WIFI setup, adding a secondary keypad, system tests, and system information. The Master Code can also be used to view the event log.

To change the Master Code, perform the following steps:

1. Enter User Management. From the main screen of either a ProSeries panel or a PROWLTOUCH or PROWLTOUCHC, click the Menu icon (≡) at the bottom of the screen, then Settings > User Management > Enter Current Master Code > Click Master User.
   
   Important Note: You can also access this screen using the Installer Code (Default 4112). However, before you can save a new Master Code, you must enter the current Master Code. This is true even if you entered this screen using the current Master Code.


2. Edit Master Code. Once you are in the Master User profile screen, click the pencil icon to the right of the PIN. You will be prompted to enter the new PIN. Enter the desired 4-digit code. You will now be prompted to Confirm new PIN. Re-enter the desired 4-digit code. Assuming you enter the same 4-digit code both times, you will then be returned to the Master User profile screen. Press the Save button in the upper right. You will now be prompted to enter the existing Master Code. If you enter the correct code, the information will be saved and you can exit User Management, or go on to add or edit additional codes. If you enter the Installer Code or anything other than the existing Master Code, you'll receive an error and the change will not be saved.


3. Exit User Management. Once you have completed managing codes, you can return to the default screen by repeatedly pressing the back arrow (<) in the upper left of the screen, or by pressing the shield icon in the lower right of the screen. This will return you to the main Security Screen.
