Q-Series Outdoor Air Relative Humidity 
and Relative Humidity & Temperature 
 
 
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.

Required Tools 
•  Phillips screwdrivers, sizes No. 1 and No. 2 
•  Medium flat-blade screwdriver 
•  Wire cutters/strippers 
•  Tape measure 
•  Medium-duty electric drill 
•  Drill bit for wall anchor hole 
•  Marker or pencil 
•  Two No. 10 screws and wall anchors 
Expected Installation Time 
30 minutes 
Prerequisites 
•  Ensure that the appropriate field wiring is 
installed. 
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.
