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.

• Left position: voltage output 0 - 10 V) factory

default.

• Right position: current output (0 - 20 mA)

2. UI - Selection of input signal type

• Left position: voltage input (0 - 10 V) factory

default.

• Middle position: current input (0 - 20 mA)

Issue

Power failure Check for proper supply voltage.

Check for wiring shorts; reset breaker.

Error message

Err1: An assigned input is not enabled or missing. All control loops, functions,

and outputs tied to this input will be disabled. Verify input connections, jumper

settings and parameter settings for the input involved.

Err3: A function refers to a disable input. Disable the function or enable the

input.

Err4: Internal failure. Product must be replaced.
