US Patent 9631833 Climate control systems, and methods relating thereto

A climate control system includes a conditioning system for controlling air conditions of a space and a drain fitting coupling a condensate drain line to an air circulation unit of the conditioning system. The drain fitting includes multiple sensors configured to detect a water level in the air circulation unit relative to the drain fitting, and to output a signal to a controller indicative of contact with water. The controller is then configured to output a signal to a thermostat of the conditioning system upon determining that the water level is indicative of the drain line being plugged or blocked. The climate control system may also include a remote service provider system that allows remote interaction with the conditioning system.
