Safety, Installation, and Operation Manual
DriSteem TCI-W11-U-H, TCI-W11-U Humidistat
READ COMPLETE INSTALLATION INSTRUCTIONS BEFORE STARTING.
WARNING
1. Contact with energized electrical circuits can cause
serious injury from electrical shock. Disconnect
electrical power to the humidifier before starting
installation.
WARNING This product must be installed by a qualified heating and air conditioning contractor. Failure to do so can
result in serious injury from electrical shock or damage to product, and can void product warranty due to
possible product misapplication.
CAUTION
1. Do not set humidity higher than recommended or
moisture can accumulate, which can cause bacteria
and mold growth or dripping water into building
spaces. Dripping water can cause property damage;
bacteria and mold growth can cause illness.
2. Do not set humidity up to recommended levels if
there is condensation on the inside of windows.
Condensation damage
can result.
THESE INSTALLATION INSTRUCTIONS ARE FOR THE HUMIDISTAT ONLY!
For DriSteem humidifier installation, follow DriSteem humidifier installation instructions.

WARNING!
Live electrical components
During installation, testing, servicing
and troubleshooting of DriSteem
products, it may be necessary to work
with live electrical components. Have
a qualified licensed electrician or other
individual who has been properly
trained in handling live electrical
components perform these tasks.
Failure to follow all electrical safety
precautions when exposed to live
electrical components could result in
death or serious injury.

DRISTEEM TCI-W11 HUMIDISTAT INSTALLATION MANUAL
INSTALLATION
• Install the controller on an easily accessible interior
wall, approximately 1.5 m above the floor in an area
of average temperature.
• Avoid direct sunlight or other heat sources (e.g. above
radiators and heat emitting equipment).
• Avoid locations behind doors, outside walls,and below
or above air discharge grills and diffusers.
• Location of mounting is less critical if external sensors
are used.
• Ensure adequate air circulation to dissipate heat
generated during operation.
• Observe local regulations.
• Do not mount in a wet or condensation prone
environment.
INSTALLATION INSTRUCTIONS
1. Connect the wires to be connected to the terminals of
the power case according to wiring diagram.
2. Install the mounting plate to the flush mounting box.
Notes:
• Make sure the nipple with the front holding screw is
facing to the ground.
• Make sure the mounting screw heads do not stand out
more than 0.2" (5 mm) off the surface of the mounting
plate.
3. Ensure the jumpers are set correctly.
4. Slide the two latches located on the top of the front
part into the hooks at the upper side of the mounting
plate.
5. Carefully lower the front part until the interconnector
reaches the mounting-plate. Continue pressing in a
gentle way until the front part is fully connected. While
inserting the connectors, a slight resistance can be felt.
This is normal. Do not use excessive force.
6. With a Phillips-type screw driver of size #2, carefully
tighten the front holding screw to secure the front part
to the mounting plate. This screw is located on the
front lower side of the unit. There is no need to tighten
the screw too much.
JUMPER CONFIGURATION
Jumpers are mounted vertically only.
