A method for remote control of structural appliances includes the steps of communicating a structural appliance with a server programmed to accept mobile device commands; communicating a mobile device with the server; issuing the mobile device commands from the mobile device to the server; converting the mobile device commands to structural appliance commands; and issuing the structural appliance commands from the server to the structural appliance, whereby wireless control of the structural appliance is established.

Method for wireless data exchange for control of structural appliances such as heating, ventilation, refrigeration, and air conditioning systems

A system for remotely monitoring and controlling an HVAC device includes a server which receives queries from an entry device and data from the HVAC device. Databases with information regarding the location and status of the HVAC devices reside on the server, as does a user name/password file, instead of in the entry device or the HVAC controller. Connection is provided over various communications links including the Internet, POTS, and GSM networks. A user with an entry device such as a handheld computer or cell phone using wireless access protocol (WAP) can change settings, obtain diagnostic information, and receive alarm messages about a plurality of HVAC devices.

Method and apparatus for connecting to HVAC device

An HVAC system is assigned a network identification for subsequent use within a communication network upon receipt of a formatted signal containing the network identification. The HVAC system stores the network identification in nonvolatile memory. The HVAC system also preferably stores a verification image of the communicated network identification so that any reading back of the network identification can be validated through comparison with the stored verification image.

Identification of HVAC systems in a communication network

HVAC control information is stored in a memory associated with a programmable processor in such a manner as to be recallable in a potentially high electrical noise environment. The HVAC control information is stored along with corresponding verification images in particular memory locations. The verification images for at least some of the HVAC control information have unique mathematical relationships with respect to the stored pieces of HVAC control information.

Noise tolerant HVAC system

HVAC control information is written in a particular manner to a memory associated with a programmable processor. The processor generates verification images of the information and stores the same along with the information in addressable memory locations. The stored information and its corresponding verification images is read back for verification as to having been correctly stored in addressable memory locations. A rewriting and rereading of the information and the respective verification images can occur up to a predetermined number of times if necessary to verify that the information and respective verification images have been correctly stored.

System for processing HVAC control information

Thermostat

An electronically controlled thermostat has an emergency power configuration which only provides long term emergency power to a real time clock. All other components of the thermostat function only for a limited period of time following a power outage. Emergency power to the other components is monitored during power outage with appropriate action being taken to assure that control information has been stored in nonvolatile memory before emergency power deteriorates to a critical level.
