Access controlled thermostat system

A system for a user to control a thermostat temperature setting, comprising:

• a housing component enclosing the thermostat, the housing and thermostat being positioned on a hand-accessible wall;
• at least one display component for displaying temperature information and control information, the temperature information including at least the actual temperature, the control information including at least prompts and messages;
• an access controller component having:
• a plurality of user-operated keys, the keys including at least a plurality of numeric keys;
• a biometric reading device for receiving biometric information from the user;
• a memory for storing and accessing information entered by the user, the information including at least a master code, a password, and a biometric record of the user;
• the access controller component being operative to:
• accept a password, the password being keyed in by the user, the display then prompting the user to key in a new thermostat temperature setting if the password matches a password stored in the memory;
• reject a keyed in password if said password does not match a stored password, the display communicating the rejection;
• accept a biometric reading and compare the reading to the stored biometric record, the display then prompting the user to key in a new thermostat temperature setting if the biometric reading matches a biometric record stored in the memory;
• reject a biometric reading if said reading does not match the stored biometric record of the user, the display communicating the rejection;
• communicate the keyed in new thermostat temperature setting to the thermostat, the thermostat being adapted to adjust the temperature setting in response to the communication;
• and accept a keyed in master code if the keyed in master code matches the master code stored in the memory, the display then prompting the master code user to key in the user's choice of the access controller component functions the user desires to modify, and further prompting for keyed in entries to make those modifications, the available modifications at least including:
• modifying the acceptable passwords by adding new passwords or eliminating then stored passwords;
• and
• modifying the biometric record by adding new biometric records or eliminating then stored biometric records;
• reject a keyed in master code if the keyed in master code does not match the master code stored in the memory.

• communicate the keyed in new thermostat temperature setting to the thermostat, the thermostat being adapted to adjust the temperature setting in response to the communication;
• accept a keyed in master code if the keyed in master code matches the master code stored in the memory, the display means then prompting the master code user to key in the user's choice of the access controller function the user desires to modify, and further prompting for keyed in entries to make those modifications, the available modifications at least including:
• modifying the acceptable passwords by adding new passwords or eliminating then stored passwords;
• and
• modifying the biometric record by adding new biometric records or eliminating then stored biometric records;
• reject a keyed in master code if the keyed in master code does not match the master code stored in the memory.

A method to control access to a thermostat at least one user in accordance with parameters set by of an operator, the thermostat being enclosed in a housing, and a controller being in electronic communication with the thermostat, in electronic communication with at least one display for displaying alphanumeric characters, and in electronic communication with user-operable keys, the controller being programmable and having a memory, the method comprising the steps of:

• accepting a master code as entered by the operator using the keys;
• allowing access to the controller memory if the master code is valid;
• accepting the operator's choice of one function from a plurality of functions for which function parameters are to be changed, including at least the functions of setting a permanent password, setting a temporary password and its duration parameters, and setting biometric access parameters;
• if the operator chose setting a permanent password, prompting for keypad entry of at least one permanent password;
• accepting the operator's keypad entry of the at least one permanent password and storing the at least one permanent password in the memory;
• if the operator chose setting a temporary password, prompting for keypad entry of at least one temporary password and duration determinative -keypad entries for each of the at least one temporary passwords;
• accepting the operator's keypad entry of the at least one temporary password and duration determinative entries and storing the at least one temporary password and duration determinative entries in the memory;
• if the operator chose setting biometric reading parameters, prompting for a biometric reading of a biometric characteristic of the at least one intended user;
• accepting the biometric reading and storing the biometric reading in the memory as a biometric record;
• controlling access to keypad entry of a thermostat temperature setting by a user by:
• accepting the user's keypad entry of a password, if the entered password matches a stored permanent or temporary password, then accepting a keypad entry of a new thermostat temperature setting;
• rejecting the user's keypad entry of a password, if the entered password does not match either a stored permanent or temporary password, then displaying the rejection;
• accepting the user's provision of a biometric reading, if the biometric reading matches a stored biometric record, then accepting a keypad entry of a new thermostat temperature setting;
• rejecting the user's provision of a biometric reading, if the biometric reading does not match a stored biometric record.
