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-point point 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.

Electrical connections
Use normal cables maybe in an EMC-save environment. In an extremely impaired EMC environment use only twisted pair and
shielded cables for input /output connections. The operating voltage must comply with the requirements for safety extra-low
voltage (SELV) as per EN 60 730. Use safety insulating transformers 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 galvanically
connected. The TCI is designed for operation of AC 24 V max. 10 A safety extra-low voltage and is short-circuit-proof.
Supplying voltages above AC 24 V to low voltage connections may damage or destroy the controller or any other connected
devices. Additionally, connections to voltages exceeding 42 V endanger personnel safety.
Observe limits mentioned in the technical specifications. Local regulations must be observed!

Control loops (Parameters 1L00—1L08, 2L00—2L08; 1A00, 2A00, 1D01, 2D01)
TCI-C11 and TCI-C13 have 1 control loop (labeled 1L). TCI-C22 has 2 independent control loops (1L and 2L). Each control
loop may utilize 6 binary (on/off) and 2 PID control sequences. Control loops and sequences are activated when output
parameters are defined.
Standby set point shift (Parameters 1L07, 2L07)
This function shifts the set point for STANDBY (unoccupied) mode. The heating set point is reduced and the cooling set point
increased by a value set in parameters
Dead zone span (Parameters 1L08, 2L08)
Dead zone span lies between the heating and the cooling set point. It is selectable withparameters. A negative dead zone is
not possible.
Minimum and maximum set point (Parameters 1L01—1L04, 2L01—2L04)
The adjustable range of heating and cooling set points may be chosen individually
Cascade control (Parameters 1L06, 2L06)
TCI-C22 features 2 independent control loops with available cascade function. In cascade control the output of the primary
loop determines the set point of the secondary loop. The output of the set-point-providing primary loop is spanned between
the min. and max. set point limits of the secondary loop. Select the cascade parameter on Loop 2 (2L06) to make Loop 1
primary. Select the cascade parameter on Loop 1 (1L06) to make Loop 2 primary. In the secondary loop you choose to
cascade with 1) the reverse sequence, 2) the direct sequence, or 3) both the reverse and the direct sequence of the primary
loop. (Heating is a reverse sequence because output from the controller rises as temperature lowers. Cooling is a direct
sequence because output from the controller rises as temperature rises.) The following example of cascade control represents
a typical pressure independent VAV application where the temperature control loop (primary) determines the set point of the
air flow control loop (secondary).
Secondary Loop Airflow (Loop 2 - 2L) Primary Loop Temperature (Loop 1 - 1L)
Parameter 2L06=2
Cascade with reverse sequence of primary loop only Output 1L spanned between min. and max. set point limits
of 2L when 1L is reverse sequence.
Min. set point heating is 20% (2L01
)
Max. set point heating is 100% (2L02) Output of 1L is spanned between 20% and 100%.
When 1L output is 50%, 2L set point is 55%
When 1L output is direct (cooling) sequence, set point 2L is fixed to min. cooling set point limit (2L03)
Set point compensation – Set point reset (Parameters 1L05, 2L05 to enable; FU00—FU07 to configure input)
Shift the set point either towards the set
point minimum (negative shift) or the set
point maximum (positive shift)
depending on an external input signal.
This is done to compensate the set point
due to a change in the environment. It is
most commonly applied to outside
temperature. Summer-winter
compensation is activated through
parameters 1L05 or 2L05. Parameter
FU00 selects the compensation input
signal, either external temperature or
analog input. Winter compensation is
active when outside temperature drops
below the upper limit of winter
compensation (FU03). Depending on
parameter FU01, the set point is shifted
towards the heating set point min. or
max. Maximum compensation is reached
when the temperature reaches the lower limit (FU02). The actual set point will in this case be equal to the min. heating set
point limit for a negative shift or the max. set point limit for a positive shift. Summer compensation is active when the outside
temperature exceeds the lower limit for summer compensation (FU05). Depending on parameter FU04, the set point is now
shifted towards the cooling set point min. or max. It reaches its max. when the temperature equals the upper limit (FU06).

The Vector Controls PID control algorithm balances accuracy with stability to achieve a stable control loop. The PID
components are adjustable through parameters to suit the application. A narrow P-band increases sensitivity. A wider P-band
increases stability. A long interval (TI) slows reaction time and adds stability. A short interval increases accuracy but can
increase swinging tendency the risk of an unstable control loop. A low integral gain factor (KI) delays the response and
provides stability. A high integral gain factor increases response but can add instability. To prevent instability the P-band
should be extended whenever the integral is active. Once the integral is activated, the speed of the control reaction must fit
to the speed of the application; else the control result may be unsatisfactory.
Proportional (P-band)
•The deviation of the input to the set point which will result in 100% output.

TCI-C Universal Controller
INPUT CHARACTERISTICS
Universal Inputs (Parameters 1U00–1U12, 2U00–2U12, 3U00–3U12, 4U00–4U12)
TCI-C11 and TCI-C13 have 2 universal inputs (1U and 2U). TCI-C22 has 4 (1U, 2U, 3U, 4U). Each universal input
has jumpers, placed only vertically, on the back of the controller. Default is 0-10 VDC with the following options:
•Analog input 0-10VDC
•Analog input 0–20mA
•RT: Temperature input (NTC) or binary open/close contact input
Analog input
Analog inputs may be further customized with parameters:
•0–10v/0–2mA (1U00=1)
•2–10v/4–20mA (1U00=2)
The display value of the input signal should be specified according to the output range of the transmitter using
parameters for signal display minimum value (1U01) and signal display maximum value (1U02). For example:
4-20mA input signal, 0-200 Pa pressure transmitter
Min. display 1U01=0, Max. display 1U02=200
4 mA
0 P
12 mA
100 P
20 mA
200 P
•Values may be displayed with no unit or as: °C/°F %P
(1U04)
With a measuring range of 0–100 and a display value of 0-100, the resolution is 0.5 below 100, 0.2 below 50, and 0.1 below
25. A signal display value 0–100, therefore, is displayed with a resolution up to 0.1 for the input measurement and 0.5 for the
set point. In our example above 0–200 P is displayed with a resolution up to 0.2 for the input and 1.0 for the set point. With
the range parameter (1U03) larger numbers may be displayed: The allowable range of -50–205 may be multiplied 10 or 100.
The largest displayable values are -990–9999.
NTC Temperature Input
Place the jumper to RT for a passive NTC sensor input. Specified accuracy can
only be guaranteed using Vector Controls Sxx-Tn10 sensors. Range values
described above also apply to temperature inputs. Limiting the range increases
resolution.
Binary Input (open/close contact)
Set the jumper for the desired UI on the back of TCI to RT (remote
temperature). Set the parameter for the same UI to analog input (1U00). An
open contact reads as a high value (100%), a closed contact as a low value
(0%).
Alarm Settings on Inputs
Each input features low and high limit alarms. Each alarm is defined with a limit, a hysteresis and an enable parameter. The
limit specifies the input signal level required to trigger the alarm. Hysteresis is the difference between input signal and limit
required to return the alarm state to normal. The hysteresis parameter is shared between low and high limit alarms of the
same input. Once an alarm is triggered it will be displayed as text (see table below). The alarm text can be set to blink
continuously (even after the conditions that triggered the alarm are no longer active) until acknowledged by pressing the
OPTION button, or only when the conditions that triggered it are active (Parameter UP15).

Input signal filtering (Parameters 1U04–4U04)
Filtering prevents unwanted fluctuation of sensor signals. The controller measures signal inputs every second and creates a
final input signal based on a number of measured values and a digital low pass filter. The number of samples taken for the
filtered control signal can be selected with this parameter.Take into account that control speed decrease as the number of
samples taken for the filter increases.
Average, minimum and maximum over a range of inputs (Parameters 1U12–4U12)
This function calculates average, minimum, or maximum values over the selected inputs. When activated on universal input 3
(3U) and input 1 (1U) the inputs averaged will be 1U and 3U; The result of the averaging will may only be used for control or
display on the largest input of the group. In this example input 3 will carry the averaged value. Input 1 will show its measured
value. The measured value of input 3 is not visible. Inputs must be of same type and range. Disabled inputs will not affect the
result as they will be omitted from the calculation.
•Average calculates the average value of all the inputs involved.
•Minimum determines the input with the minimum value.
•Maximum determines the input with the maximum value.
It is possible to use different functions on different inputs. For example min of 1U and 3U and max of 2U and 4U. It is not
possible to use different functions on one input.

INPUT CHARACTERISTICS
Auxiliary functions of the universal input
Each function below may be activated with the universal input functioning as analog input (0/2–10v, 0/4–20mA), binary
open/close contact, or resistive temperature input (NTC). For binary open/close contact inputs a high value creates an open
contact (i.e. 100%), and a low value creates a closed contact a (i.e. 0%).
Summer/winter compensation (Control loop parameters 1L05/2L05, 1L01-1L04; input parameters FU00–FU07)
Select the control loop and set point you want to affect, and minimum and maximum set points for heating and cooling with
control loop parameters (see page 4). Input parameters shift the set point toward the minimum set point (negative shift) or
towards the maximum set point (positive shift).
Auto comfort–standby mode switch (Parameters FU08–FU11)
This function is used with key card switches, occupancy sensors, etc. Set input limit 1 and 2 with possibilities below. Example:
When Limit 2 > 1, switch comfort-to-standby at the lower value, standby-to-comfort at the higher value. Standby set point
shift value is determined by control loop parameters 1L07 and 2L07.
Enable–disable (Parameters FU12–FU19)
Enable or disable the controller based on desired input values, such as high or low temperature, occupancy sensor, window
contact, etc. Can be used as AND function where several conditions must be met before disable or enable. Time schedules do
not override, but manual override is permitted. Delay times may be assigned for both enable and disable (allows for the
controller to start before validation of operation values takes place). Set input limit 1 and 2 with options below. Example:
With FU16=OFF,and Limit 2 > Limit 1, switch enable-to-disable at Limit 1, disable-to-enable at Limit 2.
Auto heat–cool mode switch (Parameters FU20-FU23)
Switch between heating and cooling based on a universal input value. The input may be from a supply media (air or water) or
outdoor air temperature sensor. For supply media temperature we recommend switching to cooling at 28°C/83°F and to
heating at 16°C/61°F. For outdoor temperature we recommend switching to cooling at 28°C/83°F, and to heating at
16°C/61°F outdoor temperature. The change between heating and cooling is delayed to avoid rapid switching (factory default
5 min.) may be changed with parameter FU21. Heat-cool status of one control loop may also be determined by the heat-cool
state of the other loop with parameter FU20 (The control loop used to determine the heat /cool state of must be set to
demand-based heating and cooling (parameter 1L23 or 2L23 = OFF). Set limit 1 and limit 2 to switch between heating and
cooling mode with the options below. (Example: when Limit 2 is greater than Limit 1, switch heat to cool at the Limit 1, cool
to heat at Limit 2.) For binary open/close contact: open is a high value (100%), closed is a low value (0%).

Alarm Settings on Outputs
A control loop, special function, digital control or analog control sequence is not active until it has been assigned an output.
Alarm function (Parameters 1A08/1A09, 2A08/2A09, 1D06/1D07, 2D06, 2D07)
In the universals input we define low limit and high limit alarms. There are a total of
8 alarms for TCI-C22: For universal input number 1 (1U) we have ALA1 low limit
and ALA2 high limit alarms, on universal input 2 (2U) we have ALA3 low limit and
ALA4 high limit alarms, etc. With the output parameters we define the output we
want to assign an alarm to and how the output should respond to that alarm. The
output can be switched on (100%) or off (0%). The alarm takes precedence over
operating state and calculated output signal. Two parameters define the behavior of
the output based on an alarm: One parameter defines which alarm deactivates the output (0%), the other parameter defines
which alarm activates the output to 100%. Each alarm can be individually selected. Multiple alarms can be signed to one
output. Should one alarm be simultaneously selected to activate and deactivate the output, the one to de-activate has
precedence.
Analog outputs
TCI-C11 and TCI-C13 have 1 analog output (AO1). TCI-C22 has two analog outputs (AO1 an AO2). Each analog
output has jumpers, placed only vertically, on the back of the controller. Default is setting 0-10 VDC with option for
0-20mA. Parameters can be set to further customize analog input ranges—0-10v/0-2mA, 2-10v/4-20mA. Additional
custom ranges can also be created by setting minimum and maximum signal limits.
Auxiliary functions of the analog output
Manual (Parameter 1A00=4)
With the manual positioning feature you can position the output directly with a set point. The number of positioning steps can
be selected: 2, 10, 100.
Dehumidifying for 4-pipe systems (Parameter 1A00=3)
The maximum value is taken of both direct acting PI sequences (cooling and dehumidifying). Cooling will start to operate if
the humidity gets too high, even if there is no cooling need, thus the heating will be forced to come into play, which in turn
dehumidifies the air.
Minimum and maximum limits for heating and cooling mode (Parameter 1A02—1A05)
Individual minimum and maximum limits for heating and cooling mode may be assigned. Limitations in cooling mode are only
used if the analog output is assigned to a control loop and that control loop has its cooling sequence active. For any other
mode, the limitations for heating mode apply.
VAV Function (individual output limits for heating and cooling)
At peak cooling airflow set point is the max. amount
of air the VAV box is set to deliver. It may be
adjusted through the max. limit on the analog
output (1A06 or 2A06). As cooling requirements
decrease, airflow dwindles until it reaches its min.
set point. This set point will be based on the airflow
needed at design cooling and is typically 10% to 15%
of max. cooling airflow. Min. airflow can be adjusted
by the min. limit on the analog output (1A05 or
2A05). When it reaches this min., the system is in
its dead band and is neither heating nor cooling. As
the system moves into heating mode, airflow
increases until it reaches the max. air flow required for heating mode. This is typically 30 to 50% of max. airflow of cooling
mode. The parameter for this is called VAV function: maximum limitation in heating mode (1A04 or 2A04).
Minimum airflow in heating mode is adjusted with 1A03 or 2A03.
Sensor and set point feedback
Values of universal inputs as well as set points of control loops may be transmitted on the analog outputs. Minimum and
maximum value of the feedback value may be set for each output.

TCI-C Universal Controller
OUTPUT CHARACTERISTICS
Binary (digital) outputs
With Parameter 1D00 set to OFF (default setting) DO1 and DO2 are used as binary (digital) outputs. They may be used for
digital heating and cooling output stages, as pulse width modulation (PWM) outputs, or for auxiliary functions.
Dehumidifying in 4-pipe systems (Parameter 1D01=3)
The maximum value is taken of both direct acting sequences of LP1 and LP2 (Cooling and dehumidifying). Cooling will come
on when humidity is above set point even without cooling demand. Heating will then come on to dehumidify the air.
State functions (Parameter 1D01=5, 1D02)
State functions activate the output based on certain conditions with or without a demand for heating or cooling, in either
comfort or standby mode. In energy hold off mode (EHO) the output will be off.
•Output is ON if the controller is ON. (Parameter 1D02=0)
•Output is ON if the controller is ON and in heating mode. (Parameter 1D02=2)
•Output is ON if the controller is ON and in cooling mode.(Parameter 1D02=3)
•Output is ON if demand exists on any other output. Typically for fan-supported heating/cooling.
(Parameter 1D02=1)
Switch OFF delay (Parameter 1D03)
The time output remains ON after there is no more demand.
Switch ON delay (Parameter 1D04)
The time demand needs to be active before the output switches on. With state functions, all control outputs are disabled
during switch ON delay.
Fan indication
Fan symbol appears on the display when DO1 is active.
PWM outputs (Parameter 1D05, when 1D00=OFF)
Pulse width modulation (PWM) mode is enabled when setting a PWM cycle time of 1 second or above with Parameter 1D05.
(PWM cycle time can be set up to 1650 seconds. A cycle time of 0 disables PWM and sets the output to binary mode). In PWM
mode the binary output will be switched on-off once per cycle. The on and off times are calculated according to the PI settings
of the respective control sequence (Parameters 1L09–1L15, 2L09–2L15).
TCI-C11 and TCI-C22 use relays for the digital outputs. It is not recommended to use cycle times below 100 seconds as the
lifetime of the relays will be shortened with frequent switching. For PWM applications requiring cycle times below 100
seconds we recommend using TCI-C13 with TRIAC outputs.
3-point outputs (Parameter 1D00=ON)
With Parameter 1D00 set to ON DO1 and DO2 are changed into one 3-point output with control characteristic according to the
PID settings of the respective control sequence (Parameters 1L09–1L15, 2L09–2L15). The running time of the actuator used
needs to be specified with Parameter 1D03. Running time is defined as the time required for the actuator to run from fully
open to fully closed or vice versa. Actuators with a fixed running time are recommended. Once fully open or fully closed the
running time for the actuator is extended for a full run-time cycle. This will allow the actuator position to be synchronized in
case it has been moved during off time or an actuator with variable running time was used. Use switching difference,
Parameter 1D04, to reduce the switching frequency of the actuator. The actuator will only move if the difference to the
current actuator position is larger than this parameter.
