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.

Use copper, twisted pair, conductors only. The operating voltage must comply with the requirements for safety extra-low
voltage (SELV) as per EN 60730. Use safety insulating transformers class II with double insulation as per EN 60742; 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 24 VAC safety extra-low voltage and is short-circuit-proof. Supplying
voltages above 24 VAC to low voltage connections may damage the controller or other devices. Connection to voltages
exceeding 42 V endangers personnel safety.

parameters set using the standard operation terminal. There are two levels:
1. User/display parameters (password 0009)
2. Control parameters (password 00241)
Recommended set-up procedure:
1. Set jumpers on the back of the controller for inputs and outputs
2. Connect power supply and inputs
3. Make sure Celsius –Fahrenheit settings are correct (UP07)
4. Program input parameters
5. Program control parameters
6. Program output parameters
7. Program auxiliary functions and user settings
8. Test function of unit
9. Switch off power
10. Connect outputs
11. Test control loop

➔Set jumper for UI1 on the mounting plate: 0...10 VDC (default), 0...20 mA, or RT/DI (passive temperature NTC or
dry contact)
➔Match sensor range to input display. With a differential pressure transmitter having 0...200 Pa measuring range set
UO1 display minimum to 0 and U02 display maximum to 200. The allowable range value of -50...205 may be
adjusted with multipliers in U03. The largest displayable values are -990...9999. Limiting range increases resolution.
Applies to analog as well as passive temperature inputs.
➔For binary input (dry contact) set the jumper and parameter to RT/DI and change unit to % (1U04 = 1). An open
contact reads as a high value (100%), a closed contact as a low value (0%).
➔Enable / Disable an alarm. Setting the alarm enable to OFF will prevent the alarm from being displayed on screen. It
may never the less be used to control an output by setting the appropriate output alarm flags. This way, an alarm
limit may be used as interlock.
➔Specify the input value that triggers an alarm. Hysteresis is the difference between alarm level input and value
required to turn the alarm off. An alarm is displayed as text if enabled (see table). Alarm text can be set to blink
continuously until acknowledged by pressing the OPTION button or only while the alarm conditions are active (see
user parameter UP15).
➔Calculate mathematical functions over multiple inputs for loop control or display with xU12. In order to calculate
average, minimum or maximum between several inputs, make sure all the inputs are of identical type and range and
then activate the same function on xU12 on all the selected inputs. The largest input of the group selected will carry
the calculated value. For example: When average is activated on 2T12 and 1U12 = 1, the average is carried on UI2.
UI2 may now be used as input for control loops and it will show the average value of UI1 and TI2 combined. It is
possible to use different functions on different inputs.
➔The differential function may only be calculated on subsequent inputs. Such as TI2-UI1. The function must only be
activated on the minuend (TI2 in this example). The displayed value of the minuend will change into the difference:
TI2 in –UI1 = TI2 out. It is possible to have multiple differentials on one controller. It is not possible to reverse the
subtraction to UI1-TI2.

➔Economy mode set points: There are two possibilities to change the set point in economy mode: Shift it by L07 or
switch to the minimum set point limit in heating mode and maximum set point limit in cooling.
Economy mode may be disabled by setting UP06 to OFF.
➔Control loops and sequences are activated when output parameters are defined.
➔Cascade control
In cascade control (L06) the set point of the secondary loop is determined by the demand of the primary loop. The
set point of the secondary loop is calculated proportionally according to demand of the primary loop between
minimum and maximum set point limits. Cascade control is activated by setting the parameter XL06 of the secondary
control loop.
A typical application is a variable air volume system where the temperature output determines the pressure set point.
Cascade control example - VAV application
Primary loop = temperature (1L)
Secondary loop = airflow/pressure (2L)
Settings: 2L01 = 20%, 2L02 = 60%, 2L06 = 2
Depending on temperature set
point, the demand is calculated for
loop 1. For example 40%.
Based on demand of loop 1, the set point of pressure loop is calculated
proportionally between min (20%) and max (60%) pressure set point limits.
A demand of 40% will result in a set point of 36% in the above example.
➔Set point compensation
The set point compensation is typically used to compensate the set point due to a change in outside temperature. The
relationship to the input used to drive the set point compensation is defined in auxiliary functions FU00 to FU07.
➔Enable summer or winter set point compensation for this control loop with L05. Define the compensation range with
L26. L26 defines the full set point shift once the compensation input has reached its lower limit in winter mode or
upper limit in summer mode.
Setting the range parameter to 0 will activate the set point setback function: The setback function shifts the set point
toward the set point minimum or the set point maximum based on an external input value. Once the compensation
input has reached its lower limit in winter mode or upper limit in summer mode, the set point is fixed to the set point
minimum or maximum value. Commonly this is used for humidity control to avoid condensation on outside walls or
windows in very cold weather.

➔Proportional control (P-band)
The proportional control function calculates the output based on the difference between set point and measured value.
The proportional band (P-band) defines the difference between set point and measured value which will result in a
100% output. For example, with a heating or reverse 0...10 V control sequence, and a 2.0 °C (4.0 °F) P-band value,
at 10 V the controller will be 2.0 °C (4.0 °F) below set point. This is the working range of the proportional control
sequence.
Setting the proportional band to 0 disables proportional control.
➔Integral and differential control
Proportional control is in most cases a very stable control mode. The flaw of proportional control alone, however, is
that the set point is normally not reached. As the measured value gets closer to the set point, the output reduces
until it reaches a point, a fraction above or below the set point, where the output equals the load. To reach the set
point and achieve a higher level in comfort the integral/differential function should be activated.
Integral gain (KI) dynamically increases the output by the selected KI value every measuring interval TI until
the set point is reached. The challenge is to prevent hunting, where the output increases too fast, the temperature
overshoots the set point, the output goes to 0, the temperature undershoots the set point, and the cycle repeats itself.
Hunting may result if the integral gain is too high or measuring interval too short. Each system is different. To
prevent instability the P-band should be extended when integral gain is active (L14 or L15 set above 0).
Setting the integral gain to 0 disables integral and differential control.

➔Cumulative stage action (L16 = 0) is typically used in electric heat applications, and single stage action (L16 = 1) in
fan speed applications. Digital stage action (L16 = 2) is especially useful in electric heat applications to generate
three steps with just two outputs. For example: Step 1 = 100W, step 2 = 200W, step 3 = 300W.
➔Switching hysteresis (L21) is the difference between switching on and switching off. A small hysteresis will increase
the number of switching cycles and thus the wear on associated equipment.
➔With switching delay (L22) cumulative stages will not switch on simultaneously. With a sudden demand or initial
power stage 2 will not start earlier than 10 seconds (default value) after stage 1 has been initiated.

➔Set jumpers on the back of the controller: 0...10 VDC (default), or 0...20 mA. Further define analog outputs with A02.
Custom ranges can be created by setting minimum and maximum signal limits.
➔A control loop, special function, digital control or analog control sequence is not active until it is assigned an output.
➔Low and high limit alarms are defined with input parameters. With output parameters assign an
alarm to an output and select output state. The required output for each alarm can be
individually selected. Multiple alarms can be signed to one output. If one alarm is selected to
simultaneously activate and deactivate an output, the one to de-activate has precedence.
➔With manual positioning (1A00 = 4) position the output by time schedule or directly in 0.5%
steps. Setting 1A01 to 0 will disable manual positioning. The output will then only be controlled by time schedule.
➔With dehumidifying (1A00 = 3) the maximum value is taken of cooling and dehumidifying. When the humidity is too
high, cooling will continue to operate, even without a demand for cooling, to dehumidify the air and heating will
activate to maintain comfort.
➔Input values of inputs and set points of control loops may be transmitted on the analog outputs.
➔For VAV function individual minimum and
maximum limits may be assigned for cooling
and heating. In VAV applications maximum
cooling output matches the maximum air
volume the VAV box is set to deliver. As
demand for airflow in cooling mode decreases,
airflow dwindles until it reaches minimum
cooling output (1A05). This minimum will be
based on the airflow needed at design cooling
and is typically 10% to 15% of maximum
cooling airflow. When this minimum is
reached the system is in dead-band –neither
heating nor cooling. Minimum airflow in
heating mode is set with 1A03. As the system
moves into heating mode, heating airflow
increases until it reaches the maximum
heating output (1A04), typically 30 to 50% of
maximum cooling airflow.

➔With manual positioning (1d01 = 4) position the output directly (ON/OFF).
➔With dehumidifying (1d01 = 3) the maximum value is taken of cooling and dehumidifying. When the humidity is too
high, cooling will continue to operate, even without a demand for cooling, to dehumidify the air and heating will

➔State functions (1d01 = 5) 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.
➔Pulse width modulation (PWM) mode is enabled with 1d00. In PWM mode the digital 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
(see control loop Parameters L09...L15). TCI-W13 and TCI-W23 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 TCY-FT with TRIAC
outputs.

➔Summer/winter compensation changes the set point due to a change in an input value, typically, but not limited to,
an outdoor temperature input. Winter compensation starts when outside temperature drops below the upper limit of
winter compensation (FU03). At maximum winter compensation the actual set point will be equal to the control loop’s
maximum heating set point (L02). Summer compensation starts when outside temperature exceeds the lower limit
for summer compensation (FU05). At maximum summer compensation the actual set point will be equal to the
control loop’s maximum cooling set point (L04). Activate summer/winter compensation with control loop configuration
parameter (L05).
➔Use comfort/economy mode changeover with key card switches, occupancy sensors, etc. Set input limit 1 and 2 with
possibilities below. Example: When Limit 2 is greater than Limit 1, switch comfort-to-economy at the lower value,
economy-to-comfort at the higher value. Activate comfort/economy changeover with loop configuration parameter

➔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.

➔Switch heating/cooling state 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 16 °C/61 °F
and to heating at 28 °C/83 °F. For outdoor temperature we recommend switching to cooling at 28 °C/83 °F and to
heating at 16 °C/61 °F outdoor temperature. These recommendations are given as suggestions. The ideal settings
may be different on the actual project depending on climatic and system conditions.
➔The change between heating and cooling is delayed to avoid unnecessary switching (FU21). Heat/cool status of one
control loop may also be determined by the heat/cool state of the other loop (FU20= 5 or 6). The control loop used to
determine the heat /cool state must be set to demand-based heating and cooling with (L23). Set limit 1 and limit 2 to
switch between heating and cooling with options below. Example: When Limit 2 is greater than Limit 1, switch heat to
cool at 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%).
