Abstract
An HVAC controller may display a user query on the display of the HVAC controller, which queries the user as to whether a utility saver switch is installed and in use. The HVAC controller may take into account whether a utility saver switch is installed and in use when determining, logging and/or reporting out diagnostic faults of the HVAC system.
Claims25
An HVAC controller configured to control one or more components of an HVAC system, the HVAC controller comprising:
- a user interface including a display;
- a memory;
- an I/O block for receiving one or more signals from the HVAC system and for providing one or more control signals to the HVAC system;
- and
- a controller coupled to the memory, the user interface and the I/O block, the controller configured to:
- monitor one or more signals received from the HVAC system via the I/O block that are related to a current performance level of the HVAC system:
- determine if the current performance level of the HVAC system falls below a minimum performance level;
- wherein when the controller determines that the current performance level has fallen below the minimum performance level, the controller is further configured to display an alert on the display of the HVAC controller in combination with a user query that queries the user about a utility load saver switch.
