Systems and methods for providing network connectivity and remote monitoring, optimization, and control of pool/spa equipment

A system for monitoring and controlling a heating system comprising:

• a first pressure sensor configured to measure exhaust pressure of a venting system of the heating system;
• a second pressure sensor configured to measure a pressure of natural gas into the heating system;
• a current sensor configured to measure current of an electric motor of the heating system;
• a flow sensor configured to measure a flow rate of water into the heating system;
• and
• a control subsystem configured to:
• compare each of the measurements of the first pressure sensor, the second pressure sensor, the current sensor, and the flow sensor with at least one of a plurality of measurement thresholds,
• compare a determined difference between the measured exhaust pressure of the venting system and a stored last recorded measurement of the exhaust pressure of the venting system and a last recorded determined difference, and
• control operation of the heating system based on at least one of the comparisons by transmitting a diagnostic message to at least one of a display of the heating system and a remote device and terminating operation of the heating system.

A system for detecting a change in performance of a venting system of a heating system comprising:

• a pressure sensor configured to measure an exhaust pressure of the venting system, and
• a control subsystem configured to
• determine a difference between the measured exhaust pressure of the venting system and a stored last recorded measurement of the exhaust pressure of the venting system,
• compare the determined difference between the measured exhaust pressure of the venting system and the stored last recorded measurement of the exhaust pressure of the venting system and a last recorded determined difference, and
• control operation of the heating system based on at least one of the comparison and the determined difference relative to at least one of a plurality of predetermined pressure thresholds.
