1. An HVAC system including a local and remote monitoring and control system, comprising:
- A. an HVAC unit located on a site for heating or cooling a conditioned space located on the site;
B. a system for locally and remotely monitoring and controlling the HVAC unit including;
i. an interface board connected to the HVAC unit and wherein both the HVAC unit and the interface board are located on the site;
ii. a thermostat operatively connected to the interface board for sensing the temperature in the conditioned space and wherein, in a normal mode of operation, the interface board passes control commands from the thermostat through the interface board to the HVAC unit;
iii. an on-board display associated with the interface board for displaying selected system variables and including a user interface that enables a user to input commands into the interface board;
iv. a local user interface device locally located and operatively connected to the interface board for enabling a user to interact with the interface board;
v. a communications module connected to the interface board and configured to enable communications to one or more remote devices via the internet;
vi. a remote server site having one or more remote servers having a main computer program and configured to interact via the internet with the communications module; and
vii. wherein the one or more remote servers;
a. acquire data and information relating to the HVAC unit via the interface board, the communication module and through the internet;
b. detect and diagnose problems with the HVAC unit based on the data and information acquired; and
c. issue commands that include a command that preempts the thermostat from issuing commands to the HVAC unit via the interface board and further issues commands for modifying the operation of the HVAC unit.

Abstract
A system and process is provided for remotely monitoring and controlling an HVAC system. Data and information relating to an HVAC unit is transmitted from the HVAC unit via the internet to a remote server. The server is programmed to detect and diagnose problems with the HVAC unit and to respond by sending command signals to the HVAC unit that address the problems or modifies the operation of the HVAC unit.

2. A method of remotely monitoring and controlling an HVAC system, comprising:
-
receiving, by one or more remote servers located on a remote server site, data and information sent from an on-site HVAC unit through an interface board operatively connected to the on-site HVAC unit and through the internet; based on the data and information received by the one or more remote servers, detecting and diagnosing problems or operating conditions of the HVAC unit; interrupting commands being sent by an on-site thermostat to the on-site HVAC unit where the commands are sent by the thermostat through the interface board operatively connected to the HVAC unit; and directing corrective commands from the one or more remote servers via the internet and through the interface board to the HVAC unit and modifying the operation of the HVAC unit.
