Why Braemar Error Code Pops Up?

While the Braemar controller unit is operating your air conditioning system, it is also monitoring and controlling every aspect of the system’s performance. If anything unusual occurs during operation, the Braemar Networker will display a spanner symbol (Error Code).

How to fix the Braemar Error Code Problem?

Reboot your system

We strongly recommend that you should try resetting your system and see if it resolve the problem before spending money on a service call. 

You can do so simply by unplugging the unit from the PowerPoint, if you cannot locate the PowerPoint, just shut down your whole house power from the switchboard, leave it out for at least 5-10 minutes and turn the power back on.
