Controlled setpoint recovery
First Claim
1. A process for controlling the operative setpoint temperature of a thermostat when the currently scheduled setpoint temperature is to change to the next scheduled setpoint temperature at a predetermined time in the future, said process comprising the steps of:
- determining whether the thermostat is to operate on the basis of a first or a second type of system for conditioning air being operatively connected to the thermostat;
selecting a predefined period of time during which the currently scheduled setpoint temperature is to change to the next scheduled setpoint temperature depending on whether the thermostat is to operate on the basis of a first or a second type of system for conditioning air being operatively connected to the thermostat;
determining when the current time is within the selected predefined period of time of the scheduled change time to the next scheduled set point temperature; and
changing the operative setpoint temperature of the thermostat by predefined amounts of temperature in calculated increments of time until the scheduled change time to the next scheduled setpoint temperature occurs whereby the operative setpoint of the thermostat gradually changes to the next scheduled setpoint during the selected predefined period of time.

Abstract
A process is disclosed for controlling the operative setpoint of a thermostat during transition from a currently scheduled setpoint temperature to the next scheduled setpoint temperature. The operative setpoint is changed by small amounts at calculated time intervals. The time intervals are a function of the transition periods allocated for different types of systems for air conditioning air that may be operatively connected to the thermostat as well as the difference between the currently scheduled setpoint temperature and the next scheduled setpoint temperature.

16. A process for controlling the operative setpoint temperature of a thermostat when the currently scheduled setpoint temperature is to change to the next scheduled setpoint temperature at a predetermined time in the future said process comprising the steps of:
-
determining whether the thermostat is to operate on the basis of a first or second type of system for conditioning air being operatively connected to the thermostat; determining when the current time is within a first predefined period of time of the next scheduled change time if the first type of heating or cooling system is indicated to be operatively connected to the thermostat; determining when the current time is within a second predefined period of time of the next scheduled change time if the second type of heating or cooling system is indicated to be operatively connected to the thermostat; changing the operative setpoint temperature of the thermostat by predefined amounts of temperature in calculated increments of time during the first predefined period of time if the first type of heating or cooling system is indicated to be operatively connected to the thermostat; and changing the operative setpoint temperature of the thermostat by predefined amounts of temperature in calculated increments of time during the second predefined period of time if the second type of heating or cooling system is indicated to be operatively connected to the thermostat. - View Dependent Claims (17, 18, 19)
