(D.) MOUNTING IN WALL ENCLOSURE
1.
Attach wires (as shown in FIGURE #1).
WARNING
Turn OFF circuit breaker or remove fuse(s) and test
that power is OFF before wiring. Wiring this control
live can cause serious risk of electrical shock
and/or damage the control, voiding the warranty.
FOR SAFETY, THIS PRODUCT MUST BE
INSTALLED IN A GROUNDED WALL ENCLOSURE. If
you are unfamiliar with methods of installing
electrical wiring, secure the services of a qualified
licensed electrician. USE ONLY COPPER WIRE, DO
NOT use aluminum wire with this device.
IMPORTANT
Read each step carefully and perform in sequence.
This control will not work or will become damaged
if wires are connected incorrectly. To prevent
damage, connect this control exactly as shown in
the installation diagrams, otherwise warranty will
be voided. Prior to wiring, straighten or clip ends of
wire such that ends of each wire are straight (if
using this control to replace an existing switch).
Strip wire insulation at the end of each wire to
expose 5/8 inch (16 mm) of copper. Where
instructed to make a connection, twist ends of
stripped wires together and twist a proper
connector clockwise until secure.
(C.) INSTALLATION STEPS
1. WARNING
To avoid fire or risk of electrical shock, turn OFF
power at circuit breaker or disconnect fuse. Test the
power is OFF before you begin wiring.
2. BEFORE YOU MOUNT THE CONTROL
(new installation) Install control in a 3½ inch deep
single-gang or multi-gang electrical wall enclosure.
OR (replacement of existing switch) remove
existing wall plate and switch device being
replaced.
3. ATTACH POWER WIRE, LIGHT WIRE, AND
FAN WIRE
Attach 120V AC 60Hz 3-wire power (Hot / Neutral /
Ground) inside the wall enclosure with a minimum
of 6 inch leads. Attach fan three wire leads inside
the wall enclosure also with minimum 6 inch leads.
If an existing power connection is used in an
existing wall enclosure you must confirm proper AC
120V Hot / Neutral / Ground are available.
4. CONNECT WIRING
General instructions for all configurations:
Make sure the wall enclosure, fan, light, and
control are properly grounded. (See FIGURE #1).
Make sure ground wire is securely fastened. Tighten all
ground screws or wire nuts securely. Use the proper
sized wire nut for #14 or #12 wire. Make sure to strip
back the copper wire 5/8 inch and twist wire and
nut clockwise.
(A.) ABOUT
This timer is designed to give you all the options, all the
control you need, to make sure your bathroom, laundry
room, sun room, or spa room gets all the ventilation it
should have. It's really two timers in one: A countdown timer
and a fresh home / Minutes Per Hour (MPH) timer ‒ and,
best of all, the two timers work together. The countdown
timer can be set anywhere from 5 to 60 minutes, and it
activates any time you manually turn the fan on. The MPH
timer can be set to anywhere from 0 to 60 minutes, and it
runs your fan for a set time every hour to expel stale air and
help you maintain good indoor air quality (just the thing for
complying with local indoor air quality standards, such as
ASHRAE 62.2). The MPH timer also sees when you've
used the countdown timer and knows not to run the fan for
a while if you've already done it. If you want to manually
shut the fan off when the MPH timer is running, you can do
that too, just by pressing the fan on/off button.
(B.) INSTALLATION INSTRUCTIONS
CAUTION

connection.
2. For indoor use only.
3. Do not exceed this control’s maximum electrical

4. Must be installed and used in accordance with
your local electrical codes.
5. If a bare copper or green ground connection is
not available in the wall box, contact a
licensed electrician for installation.
6. For use with permanently installed 120V AC
powered fans only.
7. Use only #14 or #12 copper wire connections.
