Abstract

A thermostatic control system having a configurable lock mechanism. The mechanism may be for preventing unauthorized or unintended operation of the thermostatic control system. The system may have a manual or an automatic lock out. If the manual or automatic lock out is not effected, the system may be configured to automatically effect a lock out after a certain period of time. To remove the lock out may require a coded entry. The lock out may be full or partial with respect to the functionality of the system. The lock out mechanism may be applicable to a wireless remote control of a thermostatic system; however, it may also be applicable, for instance, to a wall module thermostat.

Claims

1. A thermostat system comprising:

a thermostat module; and

a portable remote user interface unit having a connection to the thermostat module; and

wherein the portable remote user interface unit comprises a lock control mechanism for locking out control of the portable remote user interface unit by a user; and

wherein the lock control mechanism comprises a first partial lock which is manual; and

a second partial lock which is automatic; and

wherein a portion of the first partial lock which is manual for a set period of time and then becomes automatic.

2. The system of claim 1, wherein:

the lock control mechanism is selectively configurable configured for between manual and automatic lock;

if the lock control mechanism is configured for manual lock, then the portable remote user interface unit is manually locked for locking out control of the portable remote user interface; and

if the lock control mechanism is configured for automatic lock, then control of the portable remote user interface unit is automatically locked out after a configured period of time from a last operation on the portable remote user interface unit.

3. The system of claim 1, wherein the portable remote user interface unit further comprises:

a parameter sensor; and

a sensor parameter control mechanism.

4. The system of claim 3, wherein:

a partial lock of the portable remote user interface unit locks out the parameter sensor, the sensor parameter control mechanism, or another portion of the portable remote user interface unit.

5. The system of claim 3, wherein:

the thermostat module comprises an override control mechanism which is selectively configurable for either partially or completely overriding the portable remote user interface unit; and

if the override control mechanism control is configured for partially overriding the portable remote user interface unit, then partially overriding the portable remote user interface unit comprises either disconnecting the parameter sensor at the portable remote user interface unit, the sensor parameter control mechanism at the portable remote user interface unit, or another portion of the portable remote user interface unit.

6. The system of claim 1, wherein the thermostat module comprises a beeper mechanism for sounding a beeper in the portable remote user interface unit.

7. The system of claim 4, wherein:

both the full lock and the partial lock of the portable remote user interface unit are terminated with a coded entry at the portable remote user interface unit or the thermostat module; and

the portable remote user interface unit visually reveals its full lock or partial lock status.

8. The system of claim 7, wherein to remove either of the full lock or partial lock of the portable remote user interface unit, an uncoded entry to either of the portable remote user interface unit or the thermostat module is maintained for a specified period of time to remove the full lock or partial lock.

9. The system of claim 1, wherein the portable remote user interface unit comprises an override control mechanism that is configurable for overriding a certain portion or all of the functionality of the thermostat module.

10. The system of claim 7, wherein the lock control mechanism comprises an approach for coded entry recovery and/or change.

11. The system of claim 1, wherein the lock control mechanism is configurable for providing a full lock of the portable remote user interface unit.

12. A thermostatic control system comprising:

a thermostat;

one or more remote control units connected to the thermostat; and

wherein each of the one or more remote control units comprises a lock-out mechanism for disabling the respective remote control unit; and

wherein the lock-out mechanism can be configured at both the thermostat and the one or more remote control units.

13. The system of claim 12, wherein each of the one or more remote control units is assigned to a temperature control zone.

14. The system of claim 13, wherein each of the one or more remote control units has a manual lock-out or an automatic lock-out mechanism that locks out the remote control unit after a last active action on the remote control unit.

15. The system of claim 12, wherein each of the remote control units has a beeper which can be individually activated at the thermostat.

16. The system of claim 12, wherein each of the one or more remote control units comprises:

a parameter sensor;

a parameter control unit; and

wherein the lock-out mechanism disconnects the parameter sensor and/or the parameter control unit.

17. The system of claim 16, wherein if the lock-out mechanism is inactivated at the remote control unit or the thermostat, then the parameter sensor and the parameter control unit are reconnected.

18. A keylock system of a thermostat remote controller comprising:

a thermostat connected to a building air temperature control system; and

a remote controller connected to the thermostat and having a configurable lock-out mechanism; and

wherein the lock-out mechanism can be configured alternatively at either of both the thermostat and the remote controller, relative to;

electing between manual and automatic lock-out,

setting an amount of partial lockout, and

setting an amount of time before an automatic lockout occurs after usage of the remote controller.

19. The system of claim 18, wherein the lockout mechanism is configurable as to an amount of time for locking out the remote controller from a user after a last usage of the remote controller.
