TCI-W-U Universal Controller
Applications
General
TCI-W11-U: 1 independent control loop, 1 internal temperature sensor, 1 universal input (analog/binary/temp), 2
binary outputs, 1 analog output
TCI-W22-U: 2 independent control loops, 1 internal temperature sensor, 2 universal inputs, 2 binary outputs, 1
analog output.
Internal temperature sensor standard. Add replaceable humidity element as required: AES3-HT-A2 (2%), AES3-
HT-A3 (3%), or AES3-HT-A5 (5%)
Flexible application configuration is made with a parameter-setting routine using the standard operation terminal.

Temperature sensors: Use Vector Controls NTC sensors to achieve maximum accuracy:SDB-Tn10-20 (duct), SRA-Tn10
(room), SDB-Tn10-20 + AMI-S10 as immersion sensor.
Actuators: Choose modulating actuators with an input signal type of 0-10 V DC or 4-20 mA (Min. and max.signal
limitations may be set with parameters.3-pointpoint actuators with constant running time are recommended.
Binary auxiliary devices (e.g. pumps, fans, on/off valves, humidifiers, etc):Do not directly connect devices that exceed
specified limits in technical specifications – observe startup current on inductive loads.

Warning! This device is intended to be used for comfort applications. Where a device failure endangers human life and/or
property, it is the responsibility of the owner, designer and installer to add additional safety devices to prevent or detect a
system failure caused by such a device failure. The manufacturer of this device cannot be held liable for any damage caused
by such a failure.
Failure to follow specifications and local regulations may endanger life, cause equipment damage and void warranty.

Warning:
Live Electrical
Components!
During installation,
testing, servicing and
troubleshooting of
Vector Controls
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.

Installation
Install the controller on an easy accessible interior
wall, approx. 1.5 m above the floor in an area of
average temperature.
Avoid direct sunlight or other heat sources, e.g. the
area 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
temperature 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
environments.

Use copper, twisted pair, conductors only. The operating voltage must comply with the requirements for safety extra-low
voltage (SELV) as per EN 60 730. Use safety insulating transformers class II with double insulation as per EN 60 742; they
must be designed for 100% ON-time. When using several transformers in one system, the connection terminal 1 must be
galvanic connected. TCI is designed for operation of AC 24 V safety extra-low voltage and is short-circuit-proof. Supplying

Active when changing set points. Large digits show input value. Small digits show set point. Vertical bars show analog
output value. Arrows in position 1, 2 and/or 3 show active binary (digital) output stages
Override of secondary set point in cascade control
If cascade control is active, withvariable air volume (VAV) for example,the user can override the primary loop and
manually select the set point of the secondary loop-the loop is now changed to constant air volume (CAV). Typically for
tuning the VAV system.This feature may be disabled with UP02.
While the secondary loop is displayed change the set point with UP/DOWN. Override Cascade symbol appears.
Press OPTIONto move back to the temperature loop and cancel cascade override.

Power Failure
All parameters and set points are memorized and do not need to be re-entered.
Upon return of power: SetParameter UP05to keep the unit off, switch on, or operation mode before power failure.
Clock and time schedule settings retained for 48 hours (after powered for at least 10 hours).
Error messages
Err1: An assigned input is not enabled or missing. All control loops, functions and outputs tied to this input will be disabled.
Err3: A function refers to a disabled input. Disable the function or enable the input.
Err4: Internal failure. Product must be replaced.
Verify input connections, jumper settings and parameter settings for the input involved.
Manual heat – cool change
To manually change heating or cooling mode press the OPTION key for more than 2 seconds. Access to manual heat – cool
