Claim:
1. A climate control system, comprising: a conditioning system for controlling air conditions of a space, the conditioning system comprising a thermostat for controlling operation of the conditioning system; a drain fitting coupling a condensate drain line to an air circulation unit of the conditioning system to thereby allow condensate water to drain from the air circulation unit through the drain line, the drain fitting comprising multiple sensors configured to detect a water level relative to the drain fitting; and a controller coupled to the sensors of the drain fitting; wherein the sensors are configured to output a signal to the controller indicative of contact with water, wherein the controller is configured to output a signal to the thermostat upon determining that the water level is indicative of the drain line being plugged or blocked, wherein the thermostat is operable to at least partly shut down the conditioning system upon receiving the signal from the controller indicating that the drain line is plugged or blocked, and wherein the multiple sensors include at least three sensors spaced radially around an opening defined by the drain fitting such that at least one of the sensors is positioned above a centerline of the opening and at least one of the sensors is positioned below the centerline of the opening regardless of a rotational position of the drain fitting.
