The VentCool whole house fan remote control and plug-in module is an add-on to be used with a
WTT wall control. The remote control uses temperature or a timer to control the whole house fan.
The wireless plug-in module is installed in the back of the WTT wall control.
In temperature control mode, the homeowner turns on the whole house fan and sets the comfort
temperature. The VentCool whole house fan will cool the home until the indoor temperature drops
just below the comfort temperature then turn off. A built-in safety timer will turn the fan off the
following morning in case the homeowner forgets. In timer control mode, the homeowner turns the
fan on and sets the timer interval. The fan will run for the time set then turn off. The RTT wireless
remote is also used to adjust the fan speed.

Things to Know
The Wireless Remote features a motion activated digital display
that lights up and updates as soon as it’s lifted. You may hear the
mechanism for the motion detection (a small ball bearing) when
you move the wireless remote.
When you turn the fan on or off or change settings using the
WTT Wall Control, the RTT Wireless Remote settings are updated
to reflect the settings in the WTT as soon as the remote is lifted.
When you turn the fan on or off or change settings using the RTT
Wireless Remote, the WTT Wall Control settings are updated to
reflect the settings in the RTT as soon as the RTT backlight goes off.
Wireless range is about 100 feet within the home.
Homes with plaster walls with steel lathe may experience wireless
communication interference when using wireless control.
Two “starter” AAA alkaline batteries are included. It’s highly
recommended that Lithium batteries be used for a much longer
battery life.

If On is not blinking and the RTT is in Temperature Control, make sure the
Set To temperature is a few degrees lower than the Indoor temperature. On
will blink when the fan is running.
The display indicates On but the fan is not running.
If On is blinking but the fan is not running, check the wiring from the
FC3JF fan control to the whole house fan.
If an outdoor temperature sensor is installed and the outdoor temperature
is above the limit set, whole house fan operation may be delayed. When
delayed, “LIMIT” blinks.
Changing the Batteries
When the LCD is dim or unlit, it’s time to change the two AAA batteries.
It’s highly recommended that the “starter” AAA alkaline batteries be
replaced with AAA Lithium batteries for longer battery life.
Unscrew the four screws on the back of the RTT and remove the back
cover. Change the batteries. Replace the back cover and secure with the
screws.
A replacement RTT can be ordered by contacting customer service. The
replacement RTT is linked to the WTT using Step 5 on page 3.
RTT was dropped and is no longer working.
