13.23.1. Overview

The Single Zone Climate Aggregator component aggregates climate control requests from a single zone and calculates the flap positions and blower speed required to achieve the requested climate. It also monitors temperature sensors and detects faults.

13.23.2. Functions

	Title	Description
1	Aggregate Climate Requests	Aggregates the face, feet and screen flap position requests from a single climate zone into a single request. Calculates the required blower speed.
2	Calculate Flap Positions	Calculates the face, feet and screen flap positions based on the aggregated flap position request. Supports configurations with 2 or 3 flaps.
3	Detect Temperature Sensor Faults	Monitors the evaporator and vent temperature sensors and sets a fault flag if the sensor readings are outside the valid range.
4	Detect Flap and Blower Faults	Monitors the face, feet, screen and recirculation flap position feedback signals and the blower speed feedback signal. Sets a fault flag if a short circuit or open circuit is detected.
