A89WS-TH1: Air Temperature and Humidity Probe

A89WS-TO1: Air Temperature Probe

Note: The A89WS-TH1 and TO1 kits have a similar appearance and the hardware mounting is the same. The only
difference is that the A89WS-TH1 kit includes a humidity sensor in the air probe, and the A89WS-TO1 air probe does not.
For purposes of installation, the hardware assembly is the same.
Kit contains: Air sensor with cable, 2 screws, nuts.
Install the air sensor on the inside of the weather station mounting
arm with the probe facing down. The probe should be oriented
so that the sensor is in the vented sun shade area of the arm.
Use the two screws provided to attach the sensor to the arm.
Secure the screws using the nut on the
back of the arm. Tighten the screws
until the air sensor box is flush against
the back of the mounting arm.
Bring the yellow cable down the mast
and around to the control box. Plug
the cable into the connector labeled
"temp/humidity"
