Braeburn 229150 Instruction Manual

Automatic
229150
Digital Humidistat
Before Installing or Operating,
PLEASE READ ALL INSTRUCTIONS
In Automatic Mode, the Braeburn 229150 Digital Humidistat
will adjust humidity based on the outdoor temperature,
lowering the humidity in cold weather to reduce
condensation. The humidistat can operate in Manual Mode
to control humidity to a specific relative Humidity. In most
dwellings, Automatic operation is preferred to reduce
condensation on windows and within the structure.
Manual mode is necessary where the outdoor temperature
sensor cannot be installed. Manual mode may be desirable where valuable artwork, instruments
or woodwork demand constant humidity. The LCD Display is backlit and easy to read. The
humidistat can be mounted on an interior wall or on the return duct of the HVAC System.

PRECAUTIONS

This Humidistat must be installed by a Qualified Technician. Always turn off power to the HVAC
system prior to installing or servicing the humidifier or humidistat. Improper operation can
result in over or under humidification. Over humidification can result in condensation, structural
damage or mold. Condensation within a building's structure can cause a loss of structural
strength. Condensation can also enable mold and mildew growth resulting in personal injury
and damage to building structure and contents. Older and poorly insulated structures cannot
withstand the same humidity levels as newer well insulated buildings. Read these instructions
carefully. This humidistat requires a 24 volt, AC power supply. Improper voltage can cause
malfunction or damage to the control. The technical specifications for this product and the
contents of the user manual are subject to change without notice.

Duct Mount Installation

IMPORTANT: Use base without vents for
duct mount installation.
1. Choose an accessible location on the
main RETURN air duct at least 15 inches
from any duct bends.
2. Drill a 1 inch diameter hole in the center
of your desired mounting location.
3. Using the base as a template, mark
two mounting holes and rectangular
opening (for wires).
4. Using a 1/8 inch drill bit, drill two
mounting holes. Cut or drill out
rectangular opening for wires.
5. Secure base to the duct with supplied
sheet metal screws. Pull wires
through opening.
6. Connect wires (see "wiring") and then
attach humidistat body to base.

Wall Mount Installation

IMPORTANT: Use base with vents for
wall mount installation.
1. Choose a location in the living area
that is clear of drafts or excessive
amounts of humidity. Avoid mounting
near air ducts, doors or windows.
Do not install in bathrooms or kitchens.
2. Drill a 1 inch diameter hole in the center
of your desired mounting location.
3. Using base as a template, mark the
two mounting holes and rectangular
opening (for wires).
4. Using a 3/8 inch drill bit, drill two
mounting holes and gently tap in
supplied anchors. Cut or drill out
rectangular opening for wires.
5. Secure base to the wall with supplied
plastic anchors and screws. Pull wires
through opening.
6. Connect wires (see "wiring") and then
attach humidistat body to base.

Remote Sensor Installation

IMPORTANT: Keep remote sensor wires at
least 6 inches from line voltage wires.
1. If installing the optional outdoor remote
sensor, choose a location on the north or
east wall of the structure. Install above
the snow line away from air intakes or
exhaust sources.
2. Run two wire (22 gauge minimum) cable
from the humidistat SNSR1 and SNSR2
terminals to the outdoor location. Attach
wire to sensor regardless of polarity. Wire run should not exceed 200 ft.
3. Install the metal hanging bracket with the screws provided. Insert sensor into large
opening of bracket and sensor wire into small opening of bracket.
4. Use non-hardening caulk to plug any wiring holes after verifying operation of sensor.
