Installation Instructions Document No. 129-416 October 5, 2009 Q-Series Outdoor Air Relative Humidity and Relative Humidity & Temperature Sensors Item Number 129-416, Rev. BA Page 1 of 2 Product Description The Q-Series Outdoor Air Relative Humidity, and Relative Humidity & Temperature Sensors monitor and transmit changes in humidity and temperature to the building control systems. These units are especially suited for applications where precise, stable humidity sensing is required. Standard models available are 2% and 2% certified, for both humidity only and combination humidity with temperature sensing. Sensors are offered with either 4 to 20 mA or 0 to 10 Volt output signals.

Appropriate wiring is one or more twisted pair or three conductor cables (plenum or non-plenum as required) within the maximum wiring run length for the humidity/temperature controller. The maximum recommended length is 750 feet (229 m). • Ensure that all wiring complies with National Electric Code (NEC) and local regulations. Installation 1. Determine where the sensor is to be located and install the Sun Shield, AQF3100, as shown in Figure 1. The installation surface determines which mounting components are to be used. NOTE: The shield must be mounted vertically as shown in Figure 1. 2. Remove sensor cover and install plug in knockout next to sensing probe. See Figure 1 (2). 3. Pull the field wiring through the conduit and into the sensor base. See Figure 2.
