The EWC CONTROLS OAS Outside Air Sensor provides precise real-time monitoring of outside air temperature for Zoned HVAC systems. This versatile sensor can be mounted on an outside wall or air duct, connecting to a Zone Control System, Economizer, or Smart Humidistat. It requires a dedicated 2 conductor 18AWG solid copper jacketed thermostat cable for connection, avoiding proximity to line voltage circuits. The sensor is designed for outdoor installation, away from direct sunlight or exhaust vents.
