Installation with Use of
Optional House Electricity
Be sure to follow all local building codes
when installing the 110V outlet in the
attic. Best practice would be to consult an
electrical contractor.
To utilize the house electricity option
connect the Controller Module to an
AC outlet using the AC Power Adapter
provided.
DO NOT USE AN EXTENSION CORD FOR
THIS CONNECTION
Step 1
Complete steps
1-9 in the standard
installation instructions.
Step 2
Temporarily disconnect
wiring to the solar
connectors at the Controller Module.
Step 3
The AC Power Adapter comes with 4.5
feet of cord. Make sure the 110V outlet is
located within 4.5 feet. (DO NOT USE
AN EXTENSION CORD) (Figure 6)
Step 4
Connect the AC
Power Adapter to the
port on the Controller
Module as shown.
(Figure 7)
Step 5
Plug the AC Power
Adapter into the
110V power source
(outlet). (Figure 8) The
Controller Module
will display attic
temperature and relative humidity.
Step 6
¼" or ½" coaxial
staples can be used to
secure the wire to the
rafter (not provided).
(Figure 9)
Step 7
Reconnect the wiring to the solar
connectors at the Controller Module.
The Controller Module will now utilize
the solar panel AND house electricity to
optimize fan operation.
Power Source
1. Whenever available, solar power is
the default power source. On a typical
day with proper sunlight, the fan will
operate until sunset.
2. If solar power is not available, the fan
will not operate unless the Controller
Module is installed with the AC
Power Adapter connected to house
electricity. The fan will continue
operation in the following pre-set
mode for 10 hours:
i. ON for 15 minutes and OFF for 15
minutes in a 30-minute period. This
is the most effective air circulation
frequency to keep the attic
temperature close to the outside
temperature.
ii. The fan will run for a maximum
of 10 hours on intermittent house

electricity.
iii. The fan will run on solar power
whenever solar power becomes
available again.
iv. After 10 hours of running on
intermittent house electricity,
the fan will be turned off for up
to 8 hours, then turned back
on, assuming solar power is not
available during this period of time.
