Claim 0:
1. A Heating, Ventilation, and Air Conditioning (HVAC) control system, comprising:
an HVAC controller configured to send control signals for operating one or more components of an HVAC system; and
a temperature control device operably coupled to the HVAC controller, comprising:
a memory operable to store HVAC control instructions, wherein the HVAC control instructions comprise:
a first plurality of settings for the HVAC system, wherein each setting in the first plurality of settings controls the operation of the one or more components of the HVAC system; and
a second plurality of settings for the HVAC system, wherein:
each setting in the second plurality of settings controls the operation of the one or more components of the HVAC system; and
access to the second plurality of setting for the HVAC system is restricted for a user by default; and

a processor operably coupled to the memory, configured to:
receive a temperature value;
determine a load demand value based on the temperature value;
determine a load capacity value for the HVAC system;
determine the load demand value is greater than the load capacity value for the HVAC system;
identify a first particular setting from among the second plurality of settings for the HVAC system in response to determining that the load demand value is greater than the load capacity value for the HVAC system;
output a message requesting permission to operate the HVAC system using the first particular setting;
receive a response approving permission to operate the HVAC system using the first particular setting; and
send a first trigger signal to the HVAC controller to operate the one or more components of the HVAC system using the first particular setting.
