Installation Options
Batteries
The Fan-Aspirated Temp/Hum Station is solar powered and is supplied with two NiCad
C-cell batteries. At your option you may decide to install either zero, one, or two C-cell
batteries.
• Install two fan batteries for maximum length of overnight aspiration but with
slightly lower average daytime aspiration.
• Install only one fan battery for some overnight aspiration but with slightly higher
average daytime aspiration.
• Install no batteries for maximum daytime aspiration and no nighttime aspiration.
Wireless Repeater
A wireless repeater (#7624 or #7625) can be used to extend the range of wireless trans-
mission between the station and the Vantage Pro console.
Maintenance
• Keep the surfaces clean, since the Fan-Aspirated Temp/Hum Station is less effec-
tive when the surfaces are dirty. Remove dust from the solar panel and the shield
with a damp cloth.
• Remove any debris obstructing air flow through the radiation shield, e.g., leaves,
twigs, webs, and nests.
• Avoid spraying insect killer of any kind into the radiation shield as this may dam-
age the sensors and the shield.
• Once a year: replace the motor (Part # 7758 or #7759), batteries (solar-powered
models only), and remove any debris lodged inside the unit.
