Security system with HVAC fault reporting

摘要

The performance of an HVAC system in a building is monitored by connecting a thermostat to an alarm system which is equipped to provide notification of alarm conditions through telecommunication or other direct means to some responsible entity. The alarm system access to telecommunications is employed to forward indicators of HVAC fault to predetermined offsite locations from where corrective action can be provided. The system includes a presumed fault condition processor which employs data from the thermostat to indicate to the alarm system that notification should take place.
