System and method for using ramped setpoint temperature variation with networked thermostats to improve efficiency
First Claim
1. A method for controlling a thermostat for energy savings comprising:
- monitoring one or more thermostats located in a structure with a remotely located server via a network, the remotely located server located remotely from the structure;
determining, with the remotely located server, an existing setpoint of the one or more thermostats and storing the existing setpoint in a database structure associated with the remotely located server;
automatically setting, with the remotely located server, a first setpoint of a repeating sequence of discrete setpoints based at least in part on the value of the existing setpoint;
determining, with the remotely located server, a number of discrete setpoints in the repeating sequence of discrete setpoints, wherein the repeating sequence of discrete setpoints is comprise different values than the first setpoint and storing the repeating sequence of discrete setpoints in the database structure;
automatically setting, with the remote server, subsequent setpoints in the repeating sequence of discrete setpoints in the one or more thermostats, based at least in part on the repeating sequence of discrete setpoints stored in the database structure;
automatically setting, with the remote server, the one or more thermostats to the first setpoint after completing a last setpoint in said repeating sequence of discrete setpoints; and
monitoring, with the remote server, whether one or more manual inputs are made to the one or more thermostats and directing the one or more thermostats to return to the first setpoint in the event one or more manual inputs at the one or more thermostats is detected.

Abstract
The invention comprises systems and methods for ramping setpoints on thermostats controlling HVAC systems. At least one thermostat is located inside a structure and is used to control an HVAC system in the structure. At least one remote processor is in communication with said thermostat and at least one database stores data reported by the thermostat. At least one processor compares the outside temperature at at least one location and at least one point in time to information reported to the remote processor from the thermostat. The remote processor ramps the setpoint on the thermostat so as to reduce the average spread between inside temperature and outside temperature in order to reduce energy consumption with affecting comfort. The remote processor takes into account the effect of weather conditions and occupant preferences in determining whether and when to ramp setpoints.

9. A method for controlling a thermostat for energy savings comprising:
-
accessing one or more thermostats located in a structure with a remotely located server via a network, the remotely located server located remotely from the structure; determining, with the remotely located server, an existing setpoint of the one or more thermostats and storing the existing setpoint in a database structure associated with the remotely located server; automatically setting, with the remotely located server, a first setpoint of a repeating sequence of discrete setpoints to a value based at least in part on the existing setpoint; determining, with the remotely located server, a number of discrete setpoints in the repeating sequence of discrete setpoints and storing the repeating sequence of discrete setpoints in the database structure; automatically setting, with the remote server, subsequent setpoints in the repeating sequence of discrete setpoints in the one or more thermostats based at least in part on the repeating sequence of discrete setpoints stored in the database structure; automatically setting, with the remote server, the one or more thermostats to the first setpoint after completing a last setpoint in said repeating sequence of discrete setpoints; and monitoring, with the remote server, whether an override is made to the one or more thermostats by and occupant and returning to first target setpoint in response to the override by the occupant.

10. A system for automatically varying temperature setpoints for an HVAC system comprising:
-
a remotely located server comprising one or more computer processors, the remotely located sever configured monitor one or more thermostats located in a structure via a network, the remotely located server located remotely from the structure; the remotely located server configured to determine an existing setpoint of the one or more thermostats and store the existing setpoint in a database structure associated with the remotely located server; the remotely located server configured to automatically set a first setpoint of the one or more thermostats to a target inside temperature for a conditioned environment of the structure based at least in part on the existing setpoint; the remotely located server configured to automatically set at least a second setpoint of the one or more thermostats to a target inside temperature for the conditioned environment of the structure, where said second target temperature differs from said first target temperature and wherein at least said first and second setpoints are stored in the database structure; the remotely located server configured to automatically set subsequent setpoints in the one or more thermostats in the repeating sequence of discrete setpoints to increments away from the first setpoint; the remote remotely located server configured to direct the one or more thermostats to cycle through said repeating sequence of discrete setpoints; and the remotely located server configured to monitor whether one or more manual inputs are made to the one or more thermostats; and the remotely located server configured to direct the one or more thermostats to return to the first setpoint in the event one or more manual inputs to the one or more thermostats is detected. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
